Canonical Design Team: Cueing up users

Planet Ubuntu - Mon, 2014-06-09 08:57

The bottom edge swipe gesture is simple and accessible for users, so it’s strategic for application developers. By giving instant access to the most needed settings, controls, and views through the bottom edge, app developers have a powerful tool for crafting more useful and usable experiences.

In earlier postings we’ve talked about how the bottom edge can be harnessed effectively, but helping users to get curious about this special place on the interface is the key to unlocking the full value of an app. The solution is simple and elegant: smart cues.

What is a cue?

On first glance, the bottom edge cue is just a tiny label space that pops up when an app is opened, looking much like a simple tab or handle. When the user grabs it, or simply swipes up, anywhere along the bottom edge, the edge is activated normally.

The cue component can stay on screen as a label, or retract to a minimal handle that doesn’t clog the screen or distract from the user’s primary task. Finally, and perhaps most interestingly, the cue can become an app indicator bar, reminder the user about which settings are currently selected.

How to cue

For many apps, the bottom edge is ideal for providing a simple, always-accessible way for users to compose a new item like a message, note or add to a list of things. A cue for this purpose can be as straight forward as a “Create New” text label that slides up when the app is loaded to remind users of the action, but then retracts neatly to either a simple handle, or altogether, as the user interacts with other parts of the application. The minimized cue can remain on top of the screen if desired, providing users with an unobtrusive but persistent cue.

Combination cue and indicators

While a simple cue such as “create new” may be just right sometimes, but in some cases where settings or controls are located in the bottom edge, cues can work even harder, providing the user with an indicator bar of current setting. For example, in the camera app, the bottom edge cue shows the current flash setting and whether GPS tagging of photos is enabled. If the user triggers the bottom edge, controls for all of these settings are revealed.

Please and cues

Before you finalize your app design, think about how the bottom edge can help you deliver the most pleasing and effective user experience. Part of this plan should include the best use of the bottom edge cue, either as a label, a settings indicator, or both. Make it easy for users to discover what the bottom edge can do, and get more from your application.

Ronnie Tucker: RoboLinux Smooths the Linux Migration Path

Planet Ubuntu - Mon, 2014-06-09 08:48

RoboLinux is an impressive traditional Linux desktop distro. It could be an ideal vehicle for both enterprises and SOHOs to make the migration to Linux.

It comes with a few extra features that solve some of the potential problems of leaving other desktop platforms. One of its more enticing migration tools is a preconfigured virtual machine add-on that greatly reduces the IT burden of setting up Windows XP or Windows 7 to run in a VM environment within the Linux distro.

The website gives the impression that RoboLinux is unique in that it lets you run Windows in a VM setting that is immune to viruses and malware. However, all Linux distros are immune to the targeting attacks of decades-old viruses, as well as new malware. Running Windows in a VM setting within any VM-capable Linux distro will achieve the same degree of safety for Microsoft Windows.

Mohamad Faizul Zulkifli: Load Balancing On Linux Using Nexthop

Planet Ubuntu - Mon, 2014-06-09 07:42
How to get faster internet connection for your workstations ? basically the more bandwidth, the low latency, the faster internet you will get. But it depends on your networking devices too. Using a gigabits ethernet adapter while using 10/100 Megabits of networking switches wont make your packet goes through faster (vise-versa)

The theory to get faster internet is to have faster networking devices, from network adapter, cables or high speed wireless router and also a fiber internet.

Load balancing is a technique to distribute packets to multiple gateways. Aim to optimize our available resources and the most important is to maximize throughput. Using multiple connections with load balancing instead of a single connections may increase reliability through redundancy.

On Linux operating systems, route command has many options. One of them are nexthop option. The next hop, or gateway, is the address of the next station to which the packet is to be sent on the way to its final destination.

If you are using both cable and wireless, operating system such as Linux or Windows will choose which one has the lowest latency to the gateway. In this case, cable will be always the winner.

How to maximize your available resources ? The command is simple, when you are connected to both cable and wireless, just type ip route del default scope global ; ip route add default scope global nexthop via 192.168.0.1 dev eth0 weight 1 nexthop via 192.168.1.1 dev wlan0 weight 1 && ip r

ip route del default scope global - to remove the default gateway that operating system has already choose for you based on the latency to the gateway.

ip route add default scope global nexthop via 192.168.0.1 dev eth0 weight 1 nexthop via 192.168.1.1 dev wlan0 weight 1 - this command will define your gateways for your selected network adapters. You will need to readjust your gateway addresses depending on your networks configuration. In my case, my gateway for my cable connection is 192.168.0.1 and my gateway for my wireless connection is 192.168.1.1. Please notice that my wireless adapter name is wlan0.

ip r - this command will show your gateways. You will see the outputs. For example,

root@linux:~# ip r
default
nexthop via 192.168.0.1  dev eth0 weight 1
nexthop via 192.168.1.1  dev wlan0 weight 1

This script will do the magic job. When i connects to my wifi, it will automatically runs the load balancing script.

#!/bin/bash

IF=$1
STATUS=$2

if [ "$IF" == "wlan0" ]
then
    case "$2" in
        up)
        ip route del default scope global ; ip route add default scope global nexthop via 192.168.0.1 dev eth0 weight 1 nexthop via 192.168.1.1 dev wlan0 weight 1
        ;;
   esacfi
Put it on /etc/NetworkManager/dispatcher.d/ and name it as 90loadbalance.sh. This "90" in the name of the script means that this script will be executed in the last 10% of all scripts if you have a bunch of scripts to execute. Dont forget to make it executable. 

p/s - if you use desktop computer, you can install wifi usb adapter. You can try to install 3 or 5 network adapter (wifi, ethernet) to your desktop or laptop and readjust the command depending on your devices and gateways. Practically it will work, but i never tried. You also can make the script to run periodically, persistently by putting it to the crontab.








Michael Lustfield: All I Know About Cast Iron

Planet Ubuntu - Mon, 2014-06-09 05:00

Cast iron cookware is considered some of the best and most amazing stuff that anyone could ever cook with. My grandma gave me a cast iron dutch oven a while back and I never had the chance to use it because it was rusty, too big to use, and I haven't been camping in a long time. She recently passed away and my grandpa let me have the cast iron cookware.

This landed me with a decent amount of cast iron cookware, most of which was rather rusty and just kinda bad looking. It's not that they weren't cared for. Cast iron is something that you need to keep using to keep a fresh coat of seasoning on. If you don't use it, the seasoning can become ineffective and then you wind up with air and moisture getting to it. Air, moisture, and iron make rust.

Cast iron is a challenge to restore but I guarantee the reward is worth the effort.

Why Cast Iron

Cast iron is amazing, but only if you understand why.

  • Can almost always be restored
  • Holds up to high heats (if heated evenly, like in an oven)
  • As non-stick as non-stick pans get
  • Is non-stick without the Teflon crap that can't handle higher heats)
  • Will last your lifetime
  • Can be found for very cheap
  • No soap! (Don't use it!)
  • Excellent heat distribution (the #1 point)
  • Retains heat extremely well (the other #1 point)
  • You get a little bit of iron in your diet
Identifying That Iron

So, you're going to buy cast iron or looking at some now or considering looking around for it or... whatever you're doing, I don't care. You have or want cast iron cookware. You should know what you're looking at and why you do or don't want it. I learned a lot in short order and here are my foot notes.

Much cast iron cookware is not marked with a brand. It takes some research to know what particular markings mean.

Common older brands:

  • Wagner
  • Griswold
  • Lodge
  • Birmingham Stove & Range (BSR)
Age

You're not likely to run across anything older than 1700.

If the cast iron has a "gate mark", it is older than 1900. Gate marks happened when the pan was broken out of the mold. Between 1875 and 1900, they were phased out by injecting the mold at the lip of the pan instead of the bottom.

Originally, cast iron was made to fit on top of a wood stove. Wagner, Griswold, BSR, and Lodge made stoves and then made the pans that would fit those holes. This is what the size printed on the pan means. It roughly means the diameter, but not always. For a time, they were produced with a heat ring which would set right inside of the hole to help keep the pan centered. The heat ring disappeared in the late 1970's.

If the heat ring is very neat to the edge of the pan and the pan has a sharp sloped edge, it was produced prior to 1950.

If it has "Made in <anywhere>" printed on the bottom, it's made after 1960.

"Wagner 1891 Original" was produced in the 1990's.

BSR changed from <number>/<letter> to "NO. <number>" in the 1950's.

Brand

If the brand isn't printed, these are some clues to who produced it. A pan may or may not have all of these characteristics. Example: A BSR pan either had the <number>/<letter> size or it had NO. <number> for size, but not both.

Lodge:

  • Three notches in the heat ring
  • Very rounded script used for the numbers
  • Used "SK" for Skillet
  • An extra handle opposite of the handle
  • Heavier than Wagner
  • Cornbread pan with an open hole

Wagner:

  • INCH and description "SKILLET" is spelled out completely
  • Typewriter style font

Griswold:

  • Angled handle (comes to a point)
  • Italic font for size

Vollrath:

  • The size is perpendicular to the handle

Chicago Hardware Foundry:

  • Dented surface (like a golf ball)

BSR:

  • Weight is between Lodge and Wagner
  • Extremely smooth surface
  • Solid round heat ring
  • Size will also have a letter or two (the mold letter)
  • Angled ridge on the bottom of the handle
  • "NO." number abbreviation
  • Cornbread pan without an open hole

Made in Asia:

  • Rough surface
  • Saucepan with wooden handle
  • Generally poor quality iron
  • Ridges on the top of the handle
  • No, they don't have lead in them

Everything listed here, except Asian cookware, is generally great quality.

Anything produced by Favorite Stove and Range (very light), Wapak (very light), or Martin Stove Company (very heavy) are also great brands. Most iron produced in Asia was done with low quality iron.

The New Stuff

New cast iron is fine and usually comes pre-seasoned. The quality is supposedly just as good as fifty years ago, however, the pre-seasoning means something to the pan. In order to properly pre-season, they need to make the pan rough so there is something for it to adhere to. This extra roughness causes sticking and isn't much fun to clean.

Many people will strip the seasoning off and then grind the pan smooth(er) and then re-season it. They usually feel that the seasoning they put on is better anyway. This is likely true. It's especially true if you do a great seasoning job. Pre-seasoning is usually done with soybean oil. This makes the older stuff much more enticing.

Cleaning Cast Iron

There is a lot on the internet about cleaning up cast iron and making it look pretty and amazing. Well, I tried a lot of it and a lot of it utterly sucks. I even bought a nice Dremel tool to clean it up. It's a great tool to have, but not useful for this job.

Electrolysis works, but it's not something I had handy or the motivation to build, so wasn't an option for me.

Really Bad

If your cookware is full of gunk, crap, rust, stuff, and other things, then it might very well fall into this category.

The best thing to do is clean it with a green scrubby pad as well as you can without water and then wipe it clean with a damp rag. Put it upside down in your oven and put the oven on self-clean. How long it stays in there depends on how bad the build-up is.

When it's done, LET IT COOL! If you force the oven door open too soon or open it after the oven has cooled but the iron hasn't, you risk a drastic change in temperature. This change can cause the cookware to either warp or crack. When taking the cookware out, everything that was caked on should just fall off. It might not be unwise to suck up the flakes on the pan with a vacuum hose before pulling them out. Yes, rust will remain.

Once out, wash the pan with cold water and soap. The soap will help remove any lingering oils and rust. Use a green scrubby pad and some mild dish soap. Once it looks shiny and new, rinse it extremely well. You don't want any soap to remain. Dry this extremely well right away or rust will form. Do not use warm water or the rust will come back faster.

You can now move on to seasoning it.

Not That Bad

If it's not in bad condition, you may get by with just scrubbing it well with a green scrubby pad and mild dish soap, then rinsing well with water, and drying immediately might be all you need.

Sometimes a soak in vinegar can help loosen some rust. Just remember that water is the enemy of cast iron. Keep it dry when not soaking.

If it's not bad, sometimes you can season right over top of tiny amounts of rust. When coating with oil, you'll actually take some of that thin layer too.

Seasoning

This one is tricky, there are thousands of methods out there and they're all basically the same but very different.

The oil/fat you use will make a big impact. If you choose something like Crisco that has a low smoke point you will have to bake it at a much lower temp and you end up with a softer finish.

After much research, I found that the best option is flax oil. Flax oil has a smoke point of 520 °F which means you can bake it at 450 °F without worry. Flax oil and the high temp produce a very hard seasoning that won't break down so easily over time and gives a very nice black appearance.

I chose organic flax oil because it had nothing else added. The other stuff I found had extra flavorings and I didn't want that inside the iron. I wanted just the flax oil.

Flax oil and linseed oil are basically the same thing, but they are very much not interchangeable. Don't try.

Just put a small amount of oil on the pan and coat the whole thing. Use the oil sparingly. You just want to get the whole piece wet with oil. Once you've hit every part of the pan, wipe it down with an absorbent paper towel. You should no longer see any streaks from the oil. This is key to making it look nice. If it's too thick, it will pool or drip.

Once your oven is pre-heated to 450 °F, you're ready to put your piece in the oven. Leave it in there for 30-60 minutes. Turn the oven off and let it cool with the door closed. Once it's cooled completely, take it out, put another thin layer of oil on it, wipe it down, and repeat the kiln process. You may need to repeat this process three times.

On your last baking cycle, leave it in the oven for up to two hours. This helps ensure your finish will be rock hard. On the last pass, just as it gets cold enough to handle carefully, I will flip the pan over and put just a small amount of oil on it where the iron touched the rack. I do this all inside the oven to prevent hitting the iron with too much cold air.

That's all there is too it! A lot of text here, but after doing it once, it's as hard as Crisco.

Once you have a good seasoning, just using it and caring for it is enough and you shouldn't have to ever season the inside again. It's possible you may have to touch up the bottom from time to time, but that shouldn't be anything more than baking it with some oil on the bottom.

Using Cast Iron

Now that you have you're cast iron cookware, know who made it, how old it is, and have seasoned it to perfection, it's time to cook with it!

The number one tip when using cast iron is to NEVER turn you're burner to high. This is exponentially more true with electric burners. If you put the pan on a very high heat, the bottom will heat faster than the rest of the pan. If this happens too rapidly, the edges won't have time to expand and the pan will warp. This isn't instant. Over time, it will ruin the pan. Electric burners tend to focus heat which makes this even easier to do.

Start your burner on low and let the pan warm up before turning up the heat. You shouldn't ever need to bring it up above medium or maybe medium high heat. High should be avoided like your crazy ex, especially with an electric range.

Obviously, you'll probably be cooking with oil. I recommend using either peanut or olive oil. Olive oil is a bit pricey but gives the best flavors and peanut oil is the best of the cheap options. They give great flavor and help maintain an amazing seasoning.

Once your up to temp, you'll stay there cast iron doesn't lose its heat just because you dropped something cool on it. It keeps a very nice consistent and even heat. That's part of why we love it so much.

If you want a steak that has an excellent crust, pre-heat a cast-iron pan to 400-500 °F (if you used flax oil) in an oven. Take it out out of the oven and sear the steak on both sides for three minutes each side. Put it back in the oven for another three minutes on each side. If you have two cast iron pans, one can be used to sandwich the meat and cook both sides at once.

The lower temp you cook your food at, the better it will end up. On medium-low heat, get some oil sizzling. Take stems off some portobello mushrooms and put them stem side down in the pan. Put them on the side of the pan and they'll cook themselves. Put a ground beef patty in there, wait a while, flip, wait, toss on a slice of cheese, take it all off, but don't stop! Take a bakery fresh bun, split it, and toast in the remaining oil. Now you're ready for the best burger ever. Bonus points for using grass-fed ground beef.

Make sure to not cook things too hot. If you do, grease will splatter and create a mess. This mess will probably form letters. It might look something like "I don't know what I'm doing."

Cleaning Cast Iron

You just finished your amazing meal and you realized what you've been missing in life. It wasn't a dog! Now you have to clean. Take a paper towel and wipe it down. Done. Stop arguing, you're done cleaning it!

If you really insist, you can let it cool, rinse with cold water, and wipe down again. Really, though, that's it.

Don't use soap unless you plan to start seasoning from scratch immediately. Just don't use soap. Absolutely NEVER EVER use the dish washer. NEVER! Did I make my point well enough? Don't ever do it! Want to clean everything off of it and start from scratch? Still, don't ever use the dishwasher.

Conclusion

Well, there we have it. Everything I know about cast iron at the moment is right here. I hope this will help many others learn to love cast iron cookware and care for it properly.

Paul Tagliamonte: adventures in android

Planet Ubuntu - Sun, 2014-06-08 18:31

I’ve been learning about android development over the last few weeks, and I think I’m slowly getting the hang of best practices.

It’s a bit tough, there’s a lot of stuff that’s not super Java-idomatic that’s become Android-idiomatic, so getting over that stuff has been interesting.

I’ve been finding that Android tends to re-implement most things in a similar enough way, but always with some small tweak that feels kinda funny.

It’s working well enough, and I’m hoping that I can clean up a few android libraries to deal with some of the OpenGov datasets I’m interested in.

If anyone has any tips on proper handling of what to make a fragment, and what activities should look like, I’d really love posts about that.

It seems like sometimes I have a 1-to-1 mapping of Fragments to Activity, but I want to keep it a fragment for large devices.

Anyway, best practices welcome.

02:08 | WELCOME and INTRO:

Welcome to our new studio recording format. Here are a couple of pictures from the recording:

 

02:35 | Since Last Time

  • Tony - Starting to get used to his new life of leisure by getting very busy doing lots of stuff.  He attended a local computer auction and bought a couple of Lenovo X200s laptops and have been playing with these.  Also He’s been getting frustrated with LMDE, as he said on the last show he’s been having issues with audio in LMDE.  He’s now found out that it gobbles up HDD space, only installed this system about 3 months back on a 160Gig HDD which should give loads of space for applications and updates but he has started to get the low disc space warning. Even having transferred all the data he can off the drive to other storage and given the remaining space taken up in the home folder is only around 7Gb The OS has swallowed up nearly 130 Gb of space. In the end he had to reinstall Mint 16 to regain a workable system.
  • Les - Has spent a lot of time in recent months working with a class of young hackers from Mere Side Primary School in Blackpool. They designed, built and tested an emergency beacon power by Raspberry Pi and PiGlow from Pimoroni. They entered a competition from PA Consulting to find the best use of technology for the environment. It was our first time in the competition, and they came second in our group, a great result for the children. He have also been working with the Department for Work Pensions, hosting a hackday using robotics and the Raspberry Pi using Pibrella from Pimoroni which is an awesome piece of kit for £10.
  • Olly - Well it’s been a roller coaster couple of months for him, he left his old job as some of you who follow him on social media may have seen he has set up a business with a very good friend of his to provide a complete IT, Data & Telephony support service to startup and medium sized businesses including a package they’ve dubbed “Business In A Box”.  The good news for this podcast is they have made a commitment to run their business and deliver their services utilising Free and Open Source Software wherever possible, so lots more reviews of software and hints and tips will be shared on the show as they set things up and get settled in, so far they’ve setup a VPS running the company website, mail server, file server utilising NFS, LDAP and Samba (their Admin Assistant/Bookkeeper uses Windows so they needed to share files with her).  Shortly they’ll be setting up a PBX using Asterisk so they can have a business number they can stay connected to anywhere.  This is going to be quite a challenge for business partner Matt as he comes from a Microsoft and Proprietary Unix background and uses a lot of Apple products for personal stuff, including an Iphone and a MacBook Pro. So far he seems to be taking to it well, using the Motorola Moto G as a defacto business handset (we know it’s technically not FOSS software!!) he’s quite impressed with the quality of the phone for the money and how much android has come on since he last saw it, which would be around 1.4.  they have also procured Lenovo ThinkPad X240s and installed Linux Mint with Cinnamon Desktop Environment on them which Matt likes, he has also been experimenting with installing Ubuntu Server edition on a few bits of old redundant hardware as we will more than likely be using it for a standard VPS build, more about that later.

25:28 | LINUX LABS – Ubuntu 14.04 Testing

  • This experiment was a test of installation and usability of Ubuntu 14.04 on 3 different hardware specifications.
  • First was the minimum requirements, an “emachine” Intel Celeron 700Mhz with 768Mb RAM.
  • The Second was the preferred specification for running Unity Desktop a Compaq Intel Pentium 4 1.6Ghz with 768Mhz RAM
  • The Third was a reasonably modern specification of a Lenovo ThinkPad X220 with a 1.8Ghz Intel Core 2 Duo Processor with 2Gb RAM
  • We used the Ubuntu 14.04 32Bit DVD ROM install media.
  • After an hour of waiting for the installation to complete on the emachine PC we declared it lost as the installer had made no discernible progress what so ever.  We then downloaded the Lubuntu 14.04 32Bit installation media and tried again with that.
  • The Lubuntu installation also failed, which is meant to be a lightweight distro!!
  • The Compaq managed to install 14.04 but that was about as good as it got, it took 10 minutes to boot to the Login prompt, another 5 minutes to get the desktop and Unity dash to load.  It ran pretty sluggishly from then on.
  • The only real success was the Lenovo, which installed in around 20 minutes and ran pretty smoothly.

  • We didn’t get time to test the usability of the OS due to the time spent installing the various flavours of Ubuntu

39:01 | REVIEW - Official Ubuntu Server Book Third Edition by Kyle Rankin & Benjamin Mako Hill

  • This book is recommended as a no experience required introduction to the most common Linux/Ubuntu Server technologies. http://www.amazon.co.uk/Official-Ubuntu-Server-Book-Edition/dp/0133017532
  • The first part of the book takes you through the history of GNU/Linux and the history of Ubuntu and Canonical includes some of the structure a organisational decisions in the Introduction, 26 pages of it!! this seems a little superfluous as I don’t think anyone who’ll pick this book up will be unfamiliar with Ubuntu/Canonical or will read this section as they are looking for a technical guide to administering Ubuntu Server.
  • The next few chapter take you through the installation process, disk partitioning explaining the different types of partition and disk system formats and why you choose one over the other, also a brief guide to the file structure of the Linux operating system.
  • Then look at various server roles which you will select for your server, these are preconfigured profiles for packages and software to be installed so that a server can perform a particular role, such as mail server, web server, DNS and so on.
  • The book then moves onto installing specific software to undertake a specific server task such as email and web server walking you through installing Postfix, Dovecot and Apache.  The book does discuss some of the options available to you during installation and configuration but it does guide you towards the a standard setup that you would expect for most situations.
  • In summary if you are relatively new to Linux servers and want a first timers approach where you can get up and running fairly quickly with things like running a webserver then this a great book for you, well explained with a very straight forward approach.  But I would add a word of caution here, more complicated operations such as running a mail server I would move on to something more detailed after reading this book such O’Reilly’s Postfix & Dovecot books as you do need quite and in-depth knowledge of the subject.

Ronnie Tucker: Linux Kernel 3.10.41 LTS Is Available for Download

Planet Ubuntu - Sun, 2014-06-08 09:00

The latest version of this branch of the stable Linux kernel, 3.10.41, has been announced by Greg Kroah-Hartman and comes with quite a few changes and fixes.

The amount of changes and enhancements for this branch of the Linux kernel is rather large and the developers have added numerous drivers and other improvements. This is an LTS release and it’s likely that it will be updated for a long time.

If you are using any of the versions released until now in the Linux kernel 3.10.x branch, it’s recommended that you update to this current version.

Ronnie Tucker: LibreOffice 4.3 Beta 2 Is Now Available for Testing

Planet Ubuntu - Sun, 2014-06-08 08:43

The developers from The Document Foundation have released a new build in the LibreOffice 4.3 Beta branch, bringing even more changes than the latest update in the series. It looks like 4.3 will be quite interesting, but it’s going to take a while until it’s released.

Some fixes, according to the changelog, are the upper margin of the multi-page floating table for WW8 import has been fixed, the wrong text position in grouped list has been corrected, the direct formatting for numbering in .DOCX is now handled correctly, and numerous other fixes have been implemented.

Remember that this is a development version and it should NOT be installed on production machines. It is intended for testing purposes only.

Adnane Belmadiaf: How I Did Make The Ubuntu HTML5 Range Slider

Planet Ubuntu - Sat, 2014-06-07 16:00

Last week while i was attending the Canonical Client Sprint in Malta, i start looking into re-lifting some components like the CheckBox/Switch and the Slider, so in this post i'll explain how i did implement the new the Slider.

The first thing that needs be done is to remove the default styles using -webkit-appearance: none.

input[type=range] { -webkit-appearance: none; }

Now we can start adding our CSS styles, Webkit/Blink provides an easy way to style the thumb using the pseudo class ::-webkit-slider-thumb but first we need to remove the defaul styles.

input[type=range] { -webkit-appearance: none; background: linear-gradient(to right, rgba(175, 175, 175, 0.3) 0%, rgba(175, 175, 175, 0.3) 100%); background-position: center; background-size: 99% 4px; background-repeat: no-repeat; -webkit-appearance: none; width: auto; height: 36px; border-radius: 1px; overflow: hidden; margin-top: 5px; margin-bottom: 5px; } input[type=range]::-webkit-slider-thumb { -webkit-appearance: none; }

Now let's style the thumb :

input[type=range]::-webkit-slider-thumb { -webkit-box-shadow: inset 0 1px 0 rgba(0, 0, 0, 0.2); box-shadow: inset 0 1px 0 rgba(0, 0, 0, 0.2); -webkit-box-sizing: border-box; box-sizing: border-box; -webkit-appearance: none; background-color: #fff; pointer-events: none; border-radius: 3px; width: 16px; height: 16px; position: relative; }

At this point we are still missing the oragne fill color, unfortunatly Webkit/Blink doesn't provide any pseudo class to style this area like IE does, so i have tried to combine the pseudo class ::-webkit-slider-thumb and :before to create this effect.

input[type=range]::-webkit-slider-thumb:before { position: absolute; top: 6px; left: -2000px; width: 2000px; height: 4px; background: #dd4814; content: ' '; }

Ronnie Tucker: PlayCanvas 3D WebGL Game Engine Now Open Source

Planet Ubuntu - Sat, 2014-06-07 10:00

PlayCanvas is the “world’s easiest to use WebGL Game Engine”. It’s free, it’s open source and it’s backed by “amazing” developer tools. Well now isn’t this interesting.

It has been worked on for the past 3 years and now it is under the MIT license, so you can pretty much do with it as you see fit. Now it is just a matter of getting browser developers to make the experience less annoying to game inside a browser and the OS you use becomes a little less relevant.

Ronnie Tucker: Ubuntu MATE Flavor Could Arrive Soon, Prototype Looks Great Already

Planet Ubuntu - Sat, 2014-06-07 09:46

Ever since the introduction of Unity, some of the Ubuntu users have been pining after GNOME 2, the desktop environment in use until Ubuntu 11.04 arrives. It looks like it had a lot of fans and a part of the Linux community is still hoping that the good days will return.

Martin Wimpress, a MATE Desktop team member, took it upon himself to make an Ubuntu prototype featuring MATE, which greatly resembles the old style used by Canonical until 2011.

This is just preliminary work and it’s more like an experiment than anything else, but the developer had help from Canonical’s Alan Pope and he left a message saying that something interesting might come out of this: “there’s something cooking and it smells delicious. Thanks to Alan Pope for the help.”

Jamie Strandboge: Application isolation with AppArmor – part IV

Planet Ubuntu - Fri, 2014-06-06 20:20

Last time I discussed AppArmor, I talked about new features in Ubuntu 13.10 and a bit about ApplicationConfinement for Ubuntu Touch. With the release of Ubuntu 14.04 LTS, several improvements were made:

  • Mediation of signals
  • Mediation of ptrace
  • Various policy updates for 14.04, including new tunables, better support for XDG user directories, and Unity7 abstractions
  • Parser policy compilation performance improvements
  • Google Summer of Code (SUSE sponsored) python rewrite of the userspace tools
Signal and ptrace mediation

Prior to Ubuntu 14.04 LTS, a confined process could send signals to other processes (subject to DAC) and ptrace other processes (subject to DAC and YAMA). AppArmor on 14.04 LTS adds mediation of both signals and ptrace which brings important security improvements for all AppArmor confined applications, such as those in the Ubuntu AppStore and qemu/kvm machines as managed by libvirt and OpenStack.

When developing policy for signal and ptrace rules, it is important to remember that AppArmor does a cross check such that AppArmor verifies that:

  • the process sending the signal/performing the ptrace is allowed to send the signal to/ptrace the target process
  • the target process receiving the signal/being ptraced is allowed to receive the signal from/be ptraced by the sender process

Signal(7) permissions use the ‘signal’ rule with the ‘receive/send’ permissions governing signals. PTrace permissions use the ‘ptrace’ rule with the ‘trace/tracedby’ permissions governing ptrace(2) and the ‘read/readby’ permissions governing certain proc(5) filesystem accesses, kcmp(2), futexes (get_robust_list(2)) and perf trace events.

Consider the following denial:

Jun 6 21:39:09 localhost kernel: [221158.831933] type=1400 audit(1402083549.185:782): apparmor="DENIED" operation="ptrace" profile="foo" pid=29142 comm="cat" requested_mask="read" denied_mask="read" peer="unconfined"

This demonstrates that the ‘cat’ binary running under the ‘foo’ profile was unable to read the contents of a /proc entry (in my test, /proc/11300/environ). To allow this process to read /proc entries for unconfined processes, the following rule can be used:

ptrace (read) peer=unconfined,

If the receiving process was confined, the log entry would say ‘peer=”<profile name>”‘ and you would adjust the ‘peer=unconfined’ in the rule to match that in the log denial. In this case, because unconfined processes implicitly can be readby all other processes, we don’t need to specify the cross check rule. If the target process was confined, the profile for the target process would need a rule like this:

ptrace (readby) peer=foo,

Likewise for signal rules, consider this denial:

Jun 6 21:53:15 localhost kernel: [222005.216619] type=1400 audit(1402084395.937:897): apparmor="DENIED" operation="signal" profile="foo" pid=29069 comm="bash" requested_mask="send" denied_mask="send" signal=term peer="unconfined"

This shows that ‘bash’ running under the ‘foo’ profile tried to send the ‘term’ signal to an unconfined process (in my test, I used ‘kill 11300′) and was blocked. Signal rules use ‘read’ and ‘send to determine access, so we can add a rule like so to allow sending of the signal:

signal (send) set=("term") peer=unconfined,

Like with ptrace, a cross-check is performed with signal rules but implicit rules allow unconfined processes to send and receive signals. If pid 11300 were confined, you would adjust the ‘peer=’ in the rule of the foo profile to match the denial in the log, and then adjust the target profile to have something like:

signal (receive) set=("term") peer=foo,

Signal and ptrace rules are very flexible and the AppArmor base abstraction in Ubuntu 14.04 LTS has several rules to help make profiling and transitioning to the new mediation easier:

# Allow other processes to read our /proc entries, futexes, perf tracing and
# kcmp for now
ptrace (readby),
 
# Allow other processes to trace us by default (they will need
# 'trace' in the first place). Administrators can override
# with:
# deny ptrace (tracedby) ...
ptrace (tracedby),
 
# Allow unconfined processes to send us signals by default
signal (receive) peer=unconfined,
 
# Allow us to signal ourselves
signal peer=@{profile_name},
 
# Checking for PID existence is quite common so add it by default for now
signal (receive, send) set=("exists"),

Note the above uses the new ‘@{profile_name}’ AppArmor variable, which is particularly handy with ptrace and signal rules. See man 5 apparmor.d for more details and examples.

14.10

Work still remains and some of the things we’d like to do for 14.10 include:

  • Finishing mediation for non-networking forms of IPC (eg, abstract sockets). This will be done in time for the phone release.
  • Have services integrate with AppArmor and the upcoming trust-store to become trusted helpers (also for phone release)
  • Continue work on netowrking IPC (for 15.04)
  • Continue to work with the upstream kernel on kdbus
  • Work continued on LXC stacking and we hope to have stacked profiles within the current namespace for 14.10. Full support for stacked profiles where different host and container policy for the same binary at the same time should be ready by 15.04
  • Various fixes to the python userspace tools for remaining bugs. These will also be backported to 14.04 LTS

Until next time, enjoy!

Chris J Arges: using kgraft with ubuntu

Planet Ubuntu - Fri, 2014-06-06 18:50
New live kernel patching projects have hit LKML recently [1][2], and I've taken the opportunity to test drive kGraft with the Ubuntu kernel. This post documents how to get a sample patch working.
A Simple ExampleFirst, I had to take the patches from [3] and apply them against the ubuntu-utopic kernel, which is based on 3.15-rc8 as of this post. They cherry-picked cleanly and the branch I'm using is stored here [4]. In addition to applying the patches I had to also enable CONFIG_KGRAFT. A pre-built test kernel can be downloaded here [5].

Next, I created a test VM and installed the test kernel, headers, and build dependencies into that VM and rebooted. Now after a successful reboot, we need to produce an actual patch to test. I've created a github project [6] with the sample patch; to make it easy to clone and get started.

sudo apt-get install git build-essentialgit clone https://github.com/arges/kgraft-examples.git
cd kgraft-examples
make

The code in kgraft_patcher.c is the example found in samples/kgraft [7]. Now we can build it easily using the Makefile I have in my project by typing make.

Next, the module needs to be inserted using the following:

sudo insmod ./kgraft_patcher.ko

Run the following to see if the module loaded properly:

lsmod | grep kgraft

You'll notice some messages printed with the following:

[ 211.762563] kgraft_patcher: module verification failed: signature and/or required key missing - tainting kernel
[ 216.800080] kgr failed after timeout (30), still in degraded mode
[ 246.880146] kgr failed after timeout (30), still in degraded mode
[ 276.960211] kgr failed after timeout (30), still in degraded mode
This means that not all processes have entered the kernel and may not have a "new universe" flag set.  Run the following to see which processes still needs to be updated.

cat /proc/*/kgr_in_progress

In order to get all processes to enter the kernel sometimes a signal needs to be sent to get the process to enter the kernel.

An example of this is found in the kgraft-examples [6] called 'hurryup.sh':

#!/bin/bash
for p in $(ls /proc/ | grep '^[0-9]'); do
if [[ -e /proc/$p/kgr_in_progress ]]; then
if [[ `sudo cat /proc/$p/kgr_in_progress` -eq 1 ]]; then
echo $p;
sudo kill -SIGCONT $p
fi
fi
done

Here is checks for all processes that have 'kgr_in_progress' set and sends a SIGCONT signal to that process. 
I've noticed that I had to also send a SIGSTOP followed by a SIGCONT to finally get everything synced up.
Eventually you'll see:
[ 1600.480233] kgr succeeded
Now your kernel is running the new patch without rebooting!

Rhonda D'Vine: No Portland

Planet Ubuntu - Fri, 2014-06-06 12:55

This year's debconf in portland will happen without me being there. As much as I would love to be at home again, I won't be able to afford it. As much as I'd liked to help to keep portland weird, a discussion led to the feeling that I'm not welcome there and along that lines made me miss the deadline for sponsorship request due to not being very motivated to push for it because of that. And without sponsorship I won't be able to afford it, given that I need to save up for my upcoming move.

This also means I won't be able to host the Poetry Night. I hope that someone will be picking up that ball and continue it. Personally I am more motivated than ever to start writing again, given that there is currently a Bus Bim Slam (Bus Tram Slam) happening over here in Vienna and I try to attend as much stations as possible, and there will be a Diary Slam during this year's FemCamp Vienna.
I'm indifferent on whether the Debconf Poetry Night should be recorded or not. On the one hand it would be great to see people performing, on the other hand it might shy away certain personal poems that one wouldn't want to have out in the wild. Whoever picks it up, think about that part.

I wish everyone luck in Portland, and I'm looking forward to yet another great job by the video team so I can follow a few talks from at home. It sort of breaks my heart to not be able to hug you lot this year, and I wish you a great conference. We'll meet again next year in Heidelberg!

Canonical Design Team: Making ubuntu.com responsive: dealing with responsive images (10)

Planet Ubuntu - Fri, 2014-06-06 09:30

This post is part of the series ‘Making ubuntu.com responsive‘.

Deciding how you’re going to handle responsive images is a big part of most responsive projects — also, one that usually causes many headaches!

We had really interesting discussions within the team to try to find out which options were out there, being used by other people, and whether those solutions could be useful (and possible) for us.

There is a range of solutions and opinions on this matter, but ultimately it’s all down to the content and types of images your website actually has to handle, and the technical and resource limitations of your team.

We tried to keep an open mind as to what would be possible to achieve within a very small timeframe: we wanted to find a solution that would work for our content, that would be achievable within our deadlines, and obviously, that would improve the experience of the visitors to our site.

Making an image inventory

Before discussing any potential solutions, it’s important to understand exactly what type of images are used on your site, how they are created, who creates them, how they are added to the site and in which locations, how the images play with the content and whether there are different levels of importance (UI icons, purely decorative images, infographics, editorial images, etc.).

You might realise you only use UI icons and vector illustrations, or that all your images are decorative and secondary, or even that all your images are photos commissioned to professional photographers and photojournalists that add great value to your content and designs. It’s only after doing this inventory that you’ll have sufficient information to decide what to do next and what your site needs.

On ubuntu.com there are five different types of image assets:

  • Pictograms: from an existing set of pre-approved pictograms, created in various formats, in a small subset of colours
  • Illustrations: usually created using two or more pictograms, or in a similar style, in vector format
  • Photography: these can be product shots of devices, screengrabs of our operating system and applications, and sometimes other types of photographic images
  • Logos: not only Ubuntu and Canonical’s own logos, but several partner logos
  • Backgrounds: these can be anything from dot patterns to textured backgrounds

Pictograms, illustrations, photography, logos and backgrounds are part of the image arsenal of ubuntu.com.

The pictograms and illustrations are always created in vector format and can easily be exported to an SVG. Similarly, many of the logos we use on the site can be sourced in an SVG format, but many times this isn’t possible. The photography and backgrounds used on the site, however, are usually provided to us in bitmap format, that lose definition when scaled up.

With this inventory in mind, we knew we’d have to come up with different solutions for the different types of assets rather than a single solution for all images.

Scalable vectors: pictograms, illustrations and logos

We investigated the possibility of creating a font for our icons and even started this process, but quickly decided that the lack of consistent browser support wasn’t acceptable.

The decision to move from GIF and PNG icons to SVG was relatively straightforward for us, as all our icons and pictograms are created in vector format from the outset. This would allow us to have crisp, scalable icons in most browsers, whether the device has a retina screen or not.

It was at this point that we thought it would be a good idea to finally introduce Modernizr into our toolset. With Modernizr we could target browsers that don’t support SVG and serve them with a PNG image replacement.

We did run into some browser support issues, mainly with Opera Mini which doesn’t support background-size (necessary if you’re scaling the same image asset instead of creating copies at different sizes) but does support SVG. To solve this problem, Ant wrote a JavaScript snippet that detects Opera Mini and adds the class .opera-mini to the body of the document. He will be covering this in more detail in a following post in this series.

Opera Mini’s SVG rendering issues.

We have explored the possibility of dynamically changing the colours of our SVG pictograms, but haven’t yet found a solution that is compatible across browsers — we’re open to suggestions!

Bitmap formats: photography and backgrounds

This is where things usually get trickier: how do you create a balance between serving users the best quality image they can get and saving their bandwidth?

Ideally, we’d have had the time to add the ability of images to be called on the fly in the size needed, so that the user didn’t have to download a size that was not intended for his or her screen size. This is something that we still want to work on, but just couldn’t justify to be added to the scope of this first iteration of the responsive transition.

Eventually we decided to use Imager.js — made by the BBC News developers — for responsive imaging in the markup. We chose this solution as it has simple syntax and is being used in production on high traffic websites, so it was proven to work. It seemed like a simple solution that fit our needs. In simple terms, the script runs through the page, looking up placeholder elements and replacing them with the closest available image size based on the width of the container.

CSS helper classes

We’ve created three CSS classes that can be used to hide/show images and other elements according to the size of the viewport:

  • .for-small: only shows in the smallest media query viewport
  • .for-medium: only shows in the small and medium media query viewports
  • .not-for-small: doesn’t show in the smallest media query viewport

These classes give us enough flexibility to decide which images should be visible based on our breakpoints in cases where we need more control. This means if we change the breakpoints, the classes will inherit the change.

File size

Initially we were planning on creating several versions of the images on the site, for small, medium and large screen sizes, but we found out that some of the current images on the site had a much larger file size than they needed to — for example, some transparent PNGs were being used when transparency was not a requirement.

With the limited time available, we opted for focusing on reducing file sizes as much as possible for existing images as a priority. This way, we’d make our pages smaller but small higher density screens would still see crisp images, since at smaller sizes they’d be reduced to about half their original size.

You can see a comparison of the file size per section of the site before and after this process.

Section Size before Ubuntu 14.04 LTS release (KB) Size after Ubuntu 14.04 LTS release (KB) Homepage 434 193 About 1460 1787 Cloud 2809 2304 Desktop 3794 2571 Download 2921 3990 Management 991 1102 Partners 2243 2320 Phone 6943 2021 Server 1483 636 Support 679 480 Tablet 3318 1829 TV 603 733

We obtained these sizes using a combination of YSlow and PhantomJS.

Some of the sections were expanded for the Ubuntu 14.04 LTS release in April, which justifies some of the increases. The desktop, phone and tablet sections, however — the worst offenders — saw a significant reduction in file size, mainly from switching to the most appropriate file format instead of all PNGs.

Another way to create more consistency and file size savings across the site was the introduction of a pictogram and logo package. Instead of creating pictograms ad-hoc as needed, we now have a defined set of pictograms in a central location that can be reused across the site, in all its different colour variations. Because the pictograms and many of the logos are provided in an SVG format, they can be scaled to the size that is needed.

Ideas for the future

Despite the visible improvements, there are plenty of things we’d still like to explore in the way we handle images in a responsive world.

We are currently working on an asset server that will allow us to dynamically request different sizes and formats of assets (for example, SVG to PNG), which we can offset, crop, etc., right from the src property, also being far more cacheable with long expiry times. It will also make it easier to share assets, as they will be located at a permanent URL and will become findable through a database and metadata, which should encourage reuse.

These were the solutions we came up with and worked best with your timescales and resources. We’d love to hear how you’ve handled images in your responsive projects too, so let us know in the comments!

Benjamin Kerensa: Speaking at OSCON 2014

Planet Ubuntu - Fri, 2014-06-06 05:52

Mozillians at OSCON 2013

In July, I’m speaking at OSCON. But before that, I have some other events coming up including evangelizing Firefox OS at Open Source Bridge and co-organizing Community Leadership Summit. But back to OSCON; I’m really excited to speak at this event. This will be my second time speaking (I must not suck?) and this time I have a wonderful co-speaker Alex Lakatos who is coming in from Romania.

For me, OSCON is a really special event because very literally it is perhaps the one place you can find a majority of the most brilliant minds in Open Source all at one event. I’m always very ecstatic to listen to some of my favorite speakers such as Paul Fenwick who always seems to capture the audience with his talks.

This year, Alex and I are giving a talk on “Getting Started Contributing to Firefox OS,” a platform that we both wholeheartedly believe in and we think folks who attend OSCON will also be interested in.

#OSCON 2014 presents “Getting Started Contributing to Firefox OS” by @bkerensa of @mozilla http://t.co/f1iumzhg1q

— O’Reilly OSCON (@oscon) May 14, 2014

 


And last but not least, for the first time in some years Mozilla will have a booth at OSCON and we will be doing demos of the newest Firefox OS handsets and tablets and talking on some other topics. Be sure to stop by the booth and to fit our talk into your schedule. If you are arriving in Portland early, then be sure to attend the Community Leadership Summit which occurs the two days before OSCON, and heck, be sure to attend Open Source Bridge while you’re at it.

The Fridge: Renewed call for 12:00 UTC Membership Board Nominees

Planet Ubuntu - Thu, 2014-06-05 18:04

At the end of April we called for nominations to the Membership Board, this board oversees the addition of people to Ubuntu Members, needless to say we, and we would hope you, believe this to be an important part of the Ubuntu Community.

Since then the Membership Board has received some nominations, however, up to now all the received nominations are for the 22:00UTC board.

So… we are in need of people that are able to fulfill this important job specifically for the 12:00UTC.

If you fulfill the requirements to be nominated AND can do so at the all important time slot please consider either nominating yourself or somebody else (please confirm they wish to accept the nomination and state you have done so), please send a mail to the membership boards mailing list (ubuntu-membership-boards at lists.ubuntu.com) by Friday, June 20th. You will want to include some information about yourself (or the applicant you are nominating) and a launchpad profile link.

To recap on the requirements for this position

  • be an Ubuntu member (preferably for some time)
  • be confident that you can evaluate contributions to various parts of our community
  • be committed to attending the membership meetings at 12:00UTC
  • broad insight into the Ubuntu community at large is a plus

Additionally, those sitting on membership boards are current Ubuntu Members with a proven track record of activity in the community. They have shown themselves over time to be able to work well with others and display the positive aspects of the Ubuntu Code of Conduct. They should be people who can discern character and evaluate contribution quality without emotion while engaging in an interview/discussion that communicates interest, a welcoming atmosphere, and which is marked by humanity, gentleness, and kindness. Even when they must deny applications, they should do so in such a way that applicants walk away with a sense of hopefulness and a desire to return with a more complete application rather than feeling discouraged or hurt.

Without sufficient people to run the 12:00 UTC session we are in a position where it is possible that we’ll be forced to move to running only one session for Ubuntu Membership. We’d hate to see this happen, but if so, the Community Council will work closely with the Membership Board to make sure we serve the needs of the APAC region, possibly through a modified membership application process for people who are unable to attend the 22:00 UTC session.

Elizabeth K. Joseph, on behalf of the Ubuntu Community Council
