--- layout: post title: Installing Crouton on an SD Card Instructions by Craig Errington date: 2014-06-06 18:54:07.000000000 -07:00 categories: - Blog tags: [] status: draft type: post published: false meta: geo_public: '0' author: ---
crouton script, from SD card
Updated some of the instructions below
So, I’ve just been shown how to install the XFCE chroot environment onto an SD card.. (I will include instructions for internal and external). These instructions supercede all previous ones, as a lot of fixes are incorperated by the Crouton developer, and are no longer needed.
So now, you can run ChromeOS, a full Ubuntu with an XFCE desktop, literally at the same time, switch between them with a key stroke, and not use up any of the internal storage of your Chromebook…
These instructions are written for the ARM Chromebook – they will work for other devices BUT be very careful and figure out the name of your SD card using “sudo fdisk -l” before following anything below – anywhere you see “/dev/mmcblk1″ you should substitute for your SD card name.
First up, if you’re like me, you’ll want to remove your original chroot, and start again with the SD.
So first command:
1
sudo delete-chroot precise
Making an EXT4 Partition on your SD Card
(ignore this whole section it you want to install internally, I’ll give you a shout when it’s time to join back in!)
This assumes you want to use the whole SD. If you have another computer, instead of using your Chromebook – this can be replaced with “insert SD in computer, make EXT4 partition with gparted”…But this is written with the assumption you’ll be using an ARM chromebook for *all* steps.
Get into a shell
This is destructive to your SD card, kiss its content goodbye (or back it up)
First, we’ll just check the name of our SD card:
1
sudo fdisk -l
On the ARM chromebook it’s /dev/mmcblk1
Next wee’ll unmount any partitions mounted on the SD
1
sudo umount /dev/mmcblk1*
Next we’re going to create a new partition table on the SD card.
1
sudo parted /dev/mmcblk1
This will take you into the ‘parted’ application, where we can create the new table.. Execute the following line and then click enter
1
mktable msdos
Type “yes” when asked and hit return. Then type “quit” and click enter.
Reboot the chromebook to clear the mount points and stuff… (Do it, seriously)
Get back into a shell
Now we’re going to create a linux partition onto the SD card
1
sudo fdisk /dev/mmcblk1
This will take you into the ‘fdisk’ application.
Type the following in order:
1
2
3
4
n
p
1
8192
If you now execute:
1
sudo fdisk -l
you will see your new partition (notice that it’s the name of the drive with “p1″ added to the end, this will be different on the non-arm devices….), but now we need to put a file system onto it..
Execute the following command to install an ext4 filesystem:
1
sudo mke2fs -t ext4 /dev/mmcblk1p1
Eject your card
Re-insert it
Done…. Your card now has a working ext4 filesystem and we’re ready to install crouton onto it..
OK, at this point, you have a working SD Card
OR if you’re installing internally, **this is where you join back in with the instructions***
We’re back to the basics of crouton now…
First, download the script (for the most up to date download, go here: https://github.com/dnschneid/crouton – at the top of the page, you will see a link like http://goo.gl……. I’m not posting it here as it changes regularly, and these instructions need to stay up to date…)
Make sure before you download it that you delete any previous versions of the script that you might have (just in case you use an old one)..
Back in a shell, once the script is downloaded, execute:
FOR SD CARD PEOPLE::
1
sudo sh -e ~/Downloads/crouton -t xfce -p /media/removable/External\ Drive
(careful with this location – if you’re familiar with linux use your “tab” key to complete the location, it’s easier and always accurate…)
OR FOR INTERNAL DRIVE INSTALL::
1
sudo sh -e ~/Downloads/crouton -t xfce
Wait for the process to complete..Answer any prompts (like your name, and password)
Now, to launch into your new desktop, the commands are:
FOR SD CARD USERS
With SD card inserted, open a crosh window -> ctrl+alt+t
Enter the shell by typing “shell”
Type
1
2
cd /media/removable/External\ Drive/bin
sudo bash startxfce4 -c /media/removable/External\ Drive/chroots/
FOR INTERNAL INSTALLS
1
sudo startxfce4
Then to switch between the two desktops, just use the following key combo:
CTRL + ALT + SHIFT + “Back”
Enjoy!!

| 5.6 DRAFT ADDITION TO DOCUMENTATION |
|---|
| This feature has additional or changed functionality in Unity 5.6. The link below is first draft document of that addition or change. As such, the information in this document may be subject to change before final release. See first draft Light Modes documentation. |
The Mesh Renderer takes the geometry from the Mesh Filter and renders it at the position defined by the object’s Transform component.
| Property: | Function: |
|---|---|
| Cast Shadows | If enabled, the Mesh creates shadows when a shadow-casting Light shines on it. The options are On and Off to enable/disable shadows, Two Sided to allow shadows to be cast from either side of the mesh (ie, backface culling is not taken into account) and Shadows Only (that is, the shadows should be visible, but not the Mesh itself). |
| Receive Shadows | If enabled, the Mesh displays any shadows being cast upon it. |
| Motion Vectors | If enabled, the line has motion vectors rendered into the Camera motion vector Texture. See Renderer.motionVectors in the Scripting API reference documentation to learn more. |
| Materials | A list of Materials to render the model with. |
| Light Probes | Probe-based lighting interpolation mode. |
| Reflection Probes | If enabled and reflection probes are present in the Scene, a reflection Texture is picked for this GameObject and set as a built-in Shader uniform variable. |
| Anchor Override | A Transform used to determine the interpolation position when the Light Probe or Reflection Probe systems are used. |
Meshes imported from 3D packages can use multiple Materials. All the Materials used by a Mesh Renderer are held in the Materials list. Each sub-Mesh uses one Material from the Materials list. If there are more Materials assigned to the Mesh Renderer than there are sub-Meshes in the Mesh, the first sub-Mesh is rendered with each of the remaining Materials, one on top of the next. This allows you to set up multi-pass rendering on that sub-Mesh - but note that this can impact the performance at run time. Also note that fully opaque Materials, simply overwrite the previous layers, causing a decrease in performance with no advantage.
A Mesh can receive light from the Light Probe system and reflections from the Reflection Probe system depending on the settings of the Use Light Probes and Use Reflection Probes options. For both types of probe, a single point is used as the Mesh’s notional position probe interpolation. By default, this is the centre of the Mesh’s bounding box, but you can change this by dragging a Transform to the Anchor Override property (the Anchor Override affects both types of probe).
It may be useful to set the anchor in cases where a GameObject contains two adjoining Meshes; since each Mesh has a separate bounding box, the two are lit discontinuously at the join by default. However, if you set both Meshes to use the same anchor point, then they are consistently lit. By default, a probe-lit Renderer receives lighting from a single Light Probe that is interpolated from the surrounding Light Probes in the Scene. Because of this, GameObjects have constant ambient lighting across the surface. It has a rotational gradient because it is using spherical harmonics, but it lacks a spatial gradient. This is more noticeable on larger objects or Particle Systems. The lighting across the GameObject matches the lighting at the anchor point, and if the GameObject straddles a lighting gradient, parts of the GameObject look incorrect.
To alleviate this behavior, set the Light Probes property to Use Proxy Volume, with an additional Light Probe Proxy Volume component. This generates a 3D grid of interpolated Light Probes inside a bounding volume where the resolution of the grid can be user-specified. The spherical harmonics coefficients of the interpolated Light Probes are updated into 3D Textures, which are sampled at render time to compute the contribution to the diffuse ambient lighting. This adds a spatial gradient to probe-lit GameObjects.

template<class C>
class qsense::AutoPtr< C >
AutoPtr is a "smart" pointer for classes implementing reference counting based garbage collection.
To be usable with the AutoPtr template, a class must implement the following behaviour:
- A class must maintain a reference count.
- The constructors of the object initialize the reference count to one.
- The class must implement a public duplicate() method: void duplicate(); that increments the reference count by one.
- The class must implement a public release() method: void release() that decrements the reference count by one, and, if the reference count reaches zero, deletes the object.
AutoPtr works in the following way:
- If an AutoPtr is assigned an ordinary pointer to an object (via the constructor or the assignment operator), it takes ownership of the object and the object's reference count remains unchanged.
- If the AutoPtr is assigned another AutoPtr, the object's reference count is incremented by one by calling duplicate() on its object.
- The destructor of AutoPtr calls release() on its object.
- AutoPtr supports dereferencing with both the -> and the * operator. An attempt to dereference a null AutoPtr results in a error that will cause application termination. AutoPtr also implements all relational operators. Note that AutoPtr allows casting of its encapsulated data types.

[swift-evolution] What about garbage collection?

Technically speaking, reference counting is a form of garbage collection, but I get what you mean. Since there are multiple forms of GC, I'll assume that you mean a generational mark and sweep algorithm like you’d see in a Java implementation.
> It seems to me that the two principal upsides of reference counting are that destruction is (essentially) deterministic and performance is more easily predicted.
Yes, deterministic destruction is a major feature. Not having to explain what finalizers are (and why they shouldn’t generally be used) is a pretty huge. Keep in mind that Swift interops with C, so deinit is unavoidable for certain types.
More pointedly, not relying on GC enables Swift to be used in domains that don’t want it - think boot loaders, kernels, real time systems like audio processing, etc.
We have discussed in the passed using hybrid approaches like introducing a cycle collector, which runs less frequently than a GC would. The problem with this is that if you introduce a cycle collector, code will start depending on it. In time you end up with some libraries/packages that works without GC, and others that leak without it (the D community has relevant experience here). As such, we have come to think that adding a cycle collector would be bad for the Swift community in the large.
> However, it comes with many downsides:
>

Most garbage collectors have write barriers, which execute extra code when references are updated. Most garbage collectors also have safe points, which means that extra instructions get inserted into loops.
> object references cannot be atomically updated
This is true, but Swift currently has no memory model and no concurrency model, so it isn’t clear that this is actually important (e.g. if you have no shared mutable state).
> heap fragmentation
This is at best a tradeoff depending on what problem you’re trying to solve (e.g. better cache locality or smaller max RSS of the process). One thing that I don’t think is debatable is that the heap compaction behavior of a GC (which is what provides the heap fragmentation win) is incredibly hostile for cache (because it cycles the entire memory space of the process) and performance predictability.
Given that GC’s use a lot more memory than ARC systems do, it isn’t clear what you mean by GC’s winning on heap fragmentation.
> the closure capture syntax uses up an unreasonable amount of mindshare just because of [weak self]
I think that this specific point is solvable in others ways, but I’ll interpret this bullet as saying that you don’t want to worry about weak/unowned pointers. I completely agree that we strive to provide a simple programming model, and I can see how "not having to think about memory management" seems appealing.
On the other hand, there are major advantages to the Swift model. Unlike MRR, Swift doesn’t require you to micromanage memory: you think about it at the object graph level when you’re building out your types. Compared to MRR, ARC has moved memory management from being imperative to being declarative. Swift also puts an emphasis on value types, so certain problems that you’d see in languages like Java are reduced.
That said, it is clear that it takes time and thought to use weak/unowned pointers correctly, so the question really becomes: does reasoning about your memory at the object graph level and expressing things in a declarative way contribute positively to your code?
My opinion is yes: while I think it is silly to micromanage memory, I do think thinking about it some is useful. I think that expressing that intention directly in the code adds value in terms of maintenance of the code over time and communication to other people who work on it.
> Since Swift doesn't expose memory management operations outside of `autoreleasepool`, it seems to me that you could just drop in a garbage collector instead of reference counting and it would work (for most purposes).
>
> Has a GC been considered at all?
GC also has several *huge* disadvantages that are usually glossed over: while it is true that modern GC's can provide high performance, they can only do that when they are granted *much* more memory than the process is actually using. Generally, unless you give the GC 3-4x more memory than is needed, you’ll get thrashing and incredibly poor performance. Additionally, since the sweep pass touches almost all RAM in the process, they tend to be very power inefficient (leading to reduced battery life).
I’m personally not interested in requiring a model that requires us to throw away a ton of perfectly good RAM to get an “simpler" programming model - particularly on that adds so many tradeoffs.

I was browsing through the caffeine vault and noticed the estimated fatal dose in humans is one to four grams, depending on body weight and tolerance.
At the time, I was an inexperienced novice drug user. As a child, I could drink a 12-pack of cola and not feel any stimulant effects whatsoever. I began taking Vivarin in moderate doses (three or four pills) at school to initiate a pseudo-mania state of mind or to mimic the effects of crystal meth (so I thought). On April Fool’s Day, I was bored and took four Vivarin during a lunch period on an empty stomach. Having taken the same number of pills the previous week with no side effects, I was confident that exceeding this dose “slightly” would have no consequences. Approximately twenty minutes later, I popped four more.
When lunch period ended, I headed for class with a mild stomachache. I wasn’t aware what I had gotten myself into and assumed it would take care of itself. Within ten minutes, I knew something was seriously wrong when the nausea grew worse. Some of my classmates began to show concern as I no longer could contain myself to act like a civilized student and displayed symptoms of physical discomfort. My body was burning, sweating, and shaking uncontrollably and the room became a dizzy spin.
Luckily, we weren’t doing much in class, and I asked my teacher if I could call my mother because I felt sick. He granted permission and gave me advice not to trust cafeteria food. As I waited outside for my ride, I spewed out yellow vomit. When my mom arrived, I still had the urge to throw up. I lied to her about my illness and blamed it on the cafeteria food. Having no significant prior history of drug abuse, she believed me. Once or twice (I don’t remember exactly) she pulled over to let me puke.
My sickness grew even worse when I came home. I cancelled my drum lessons and went straight to bed with a bucket near me. You can imagine the amount of sleep I got was next to none. My parents were convinced it was food poisoning, but I knew the truth. I called my girlfriend at the time for comfort since I felt she would understand being fairly knowledgeable about drugs. When I informed her what was going on, she initially thought it was an April Fool’s joke since it was April 1st. It didn’t take her long to figure I was in a state of delirium and sheer agony. Boy, I sure wish I were joking.
I puked and dry-heaved many times over, more than I ever have that night. Uncontrollably shaking, I mumbled and pleaded for the misery to go away, but it didn’t for at least twelve hours. It was a slice of purgatory torment. I don’t think I came close to dying, but I definitely came to the realization how simple caffeine, if not taken as directed, can make you really sick.
Since that crazy night on April Fool’s Day, more than six years later, I still have a strong sensitivity to caffeine. Now I easily feel the psychoactive stimulant effects from only drinking one cola, but I suppose this is normal. I believe while drugs generally cause a person to develop a tolerance, substances also have the potential to induce a reverse tolerance if taken in extreme.

The 2000-2001 draft season for the FGL is now open [no it's not]. Within your limited budget and restricted floorspace, you are trying to hire the best virtual graphics research lab possible. You can spend up to 400 Quatloos and have room to hire 12 people for the next year for your lab. You can hire from a list of 517 people. These people are researchers who have been authors of one or more SIGGRAPH papers in the past five years, 1996-2000. Each person is given a cost in Quatloos, based on their past performance. The deadline for hiring your lab is midnight of January 10, 2001, same as the SIGGRAPH 2001 papers deadline. You can enter more than once, and only your last entry will be used.
Your performance is judged by how your people do at SIGGRAPH 2001. If one of your researchers is an author on a SIGGRAPH 2001 technical paper, you receive 60/(# of authors) points. If one of your researchers is the first author on a technical sketch (not a paper), you receive 20 points. Sum up the points and that's your performance rating. Come in first in the field of contenders and you may win a 1.9 GHz laptop with a GeForce5 or win a Playstation 9. Key word: "may".
For more information and all the good jokes, see last year's contest page and last year's results.
If you're ready for action and adventure, HIRE

Error handling patterns provide guidance on how to present error messages depending on the context.
Make error and warning messages short and succinct, and use a conversational, human-voice approach. When possible, offer a solution along with an explanation of why the error or warning is occurring. Use the error component to provide a consistent user experience with error messages.
Errors can frustrate users and sometimes indicate serious problems, so be thoughtful and helpful with the wording. Limit the use of "please" and "sorry," be careful about how you use "can't" and "don't" (and avoid "you can't" and "you don't"), and avoid humor.
Don't rely on a single sensory characteristic of components such as shape, size, visual location, orientation, or sound to describe an error or offer a solution. "Above" and "below" are fine for referencing content in the appropriate reading order for the language used as long as the reference isn't ambiguous.
Error messages should be as specific as possible to help the user determine what is wrong.
The error message images apply to different scenarios and should be used accordingly.
Use this image for:
Use this image for:
Use this image for:
Use this image for:
Do not use an image for errors:
A variety of page-level errors can occur, usually due to system failures rather than user actions. The error component includes default content that applies to most scenarios, and the content can be customized if necessary to be more precise or prescriptive.
For information about validation and error handling on forms, see the form design guidelines.
Modals usually have plenty of space to display error messages, so use the error component.
Tabs that are used as a secondary navigation usually have views with plenty of available space to display error messages, so use the error component.
Tiles have limited space and may not be important to users' immediate tasks, so exclude the images and buttons and only display error messages in order to minimize the visual weight.
Since background processes run outside the current page context, use toasts to notify the user of an error with a background process. Toasts appear regardless of which page users are on and persist as they navigate through the system.

US Told To 'Stop Flexing Muscles' In South China Sea
China urged the United States to not to "provoke and escalate tensions" in the region.
by Tom SablesAmerican aircraft carrier USS Theodore Roosevelt in the South China Sea (Picture: US Department of Defense).
China has told the United States to 'stop flexing muscles in the South China Sea', during closed-door talks between defence officials.
Representing the two world superpowers, US Defense Secretary Mark Esper and Chinese Defense Minister Wei Fenghe met in Bangkok to discuss tense relations.
According to a spokesperson, Mr Fenghe called on the US not to "provoke and escalate tensions" in the waters - which are rich in oil and gas reserves.
China claims most of the busy waterway, with military outposts on several artificial islands.
The US believes China of trying to intimidate Asian neighbours such as Brunei, Malaysia and Vietnam - also with claims to some shares of the sea, through large-scale militarisation.
The United States Navy regularly carries out “freedom of navigation” operations close to Chinese-occupied islands.
During the meeting, which Mr Esper has called an effort towards continued relations "focused on maintaining the international rules-based system" followed for decades, Mr Fenghe said:
"We [call on] the U.S. side to stop intervening in the South China Sea and stop military provocation in the South China Sea."
One day prior to the meeting, Mr Esper accused Beijing of "increasingly resorting to coercion and intimidation to advance its strategic objectives" in the area.
During the meeting, the pair also discussed recent protests in Hong Kong and democratic Taiwan - which is claimed by China.
Mr Fenghe said China would "not tolerate any Taiwan independence incident".
China has previously threatened to attack Taiwan if it moves towards independence.
The previous day, as Mr Esper criticised China's intimidation strategies, China marked the start of Taiwan's presidential election campaigns by sailing a carrier group into Taiwan Strait.

After my last post on [What I Hate About Mercurial][hate], seydar commented
that I should contribute a patch to add untrack/forget functionality.
It's a very, very simple change and I'm not sure if it will even make it into
the core repository, but even so it gave me a chance to figure out how to set
up a decent development environment for hacking on Mercurial. I figured that
other people might find that information useful so I decided to write this.
[hate]: http://stevelosh.com/blog/entry/2009/5/29/what-i-hate-about-mercurial/
[TOC]
About This Guide
----------------
This is meant to be a guide to get yourself set up to work on Mercurial's code
base and contribute your work back to the community. It's *not* a guide for
actually working on the code.
I'm going to go ahead and assume a few (small) things:
1. You're running OS X or some form of Linux. If you're using Windows, I'm
sorry, but I just don't use it enough to really help.
2. You've got [Python][] installed.
3. You've got a copy of Mercurial installed in some way (MacPorts, apt-get,
source, etc).
4. You're familiar with (and have clients for) IRC and email.
If those things are true, let's get started. The entire process should take
between 15 and 45 minutes, depending on how comfortable you are with bash,
Python, and Mercurial itself.
[Python]: {{links.python}}
Join the Community
------------------
The first step to contributing is to join the community. Things will probably
go more smoothly if other developers have seen your name before and those
other developers are a great resource if you get stuck.
Join the [#mercurial channel on Freenode][irc]. A lot of other Mercurial
developers hang out in there and it's a good place to go if you want some
really quick feedback. Take a few minutes and [register your nick][register]
on Freenode, just because it's a good thing to do.
You should also [subscribe][] to the Mercurial development [mailing list][].
That's where you're going to be sending your work, so it's good to start
getting an idea of how people use the list as soon as possible.

Grab the Source
---------------
Now you'll want to grab the Mercurial source code so you can start changing
it. The repository you almost certainly want to clone is the [crew
repository][].
Several people (listed [here][crew members]) have write access to this and
it's where most changes go before they're pulled into the main Mercurial
repositories. Your want your changes to apply cleanly to the tip of crew if
you want them to have the best chance of being accepted.
Go ahead and clone it somewhere on your machine (replace `hg-crew` if you
prefer a different name for the folder):
:::text
hg clone http://hg.intevation.org/mercurial/crew hg-crew
It's going to take a little while. Mercurial might be fast but its repository
has over 8,600 changesets. While you're waiting you can move on to the next
step.

Set Up virtualenv
-----------------
This might not seem like it's necessary, but trust me, it's a good thing to
do. It will make things easier down the road, I promise.
No, *really*, take ten minutes and do this. You'll thank me.
[virtualenv][] is a tool that lets you create separate Python development
environments that are isolated from each other. The packages and binaries for
one won't contaminate the others. It will make testing our work on Mercurial
painless.
Open a new terminal window while the crew repository is busy cloning. Install
virtualenv in the usual Python fashion:
:::text
sudo easy_install virtualenv
Now install the [virtualenvwrapper][] tool:
:::text
sudo easy_install virtualenvwrapper
This is a nifty little shell script that makes working with virtual
environments much more pleasant. Before you can use it, you'll need to source
it into your `~/.bashrc` or `~/.bash_profile` file, as well as choose a place
to stick the environments themselves:
:::bash
export WORKON_HOME=$HOME/lib/virtualenvs
source /(path to python)/bin/virtualenvwrapper_bashrc
As you can see, I prefer to put the `virtualenvs` folder inside my `~/lib`
folder. You can change that to any place you like.
You'll also need to replace the `(path to python)` with the actual path to
wherever Python is installed on your system. If you're not sure, here's a
simple, slow, and horribly inefficient but effective command to figure it out:
:::text
find / -name 'virtualenvwrapper_bashrc' 2> /dev/null
Once you've got the necessary lines in your `~/.bashrc` you can close that
terminal window.

[virtualenvwrapper]: http://www.doughellmann.com/projects/virtualenvwrapper/
Set Up A Public Repository
--------------------------
This isn't strictly required, but it's polite and only takes a minute or two.
If you've already got a method of sharing your repositories (using hgwebdir
with your website, for example) go ahead and use that.
If not, head over to [BitBucket][], sign up for an account if you don't
already have one (it's free), and create a new public repository there. I've
named mine [hg-crew-sjl][] to be explicit about what it contains, but that's
not terribly important.
Why bother doing this when you're just going to email your work anyway? Some
people (myself included) find it easier to pull changes from another
repository than to apply them from emails. It also gets your changes out into
a public place so other developers can view and modify *your* modifications.
It's also nice to have an easily accessible clone of your personal repository
if you're not at your own machine and want to do some more work.
[BitBucket]: http://bitbucket.org/
[hg-crew-sjl]: http://bitbucket.org/sjl/hg-crew-sjl/
Set Up Your Local Clone
-----------------------
By now the crew repository should be finished cloning to your local machine.
The first thing we want to do is set up the paths so we can push and pull
easily. Modify the `.hg/hgrc` file inside that repository (*not* your
`~/.hgrc` file!) to look like this:
:::ini
[paths]
default = http://bitbucket.org/(username)/(repo name)/
crew = http://hg.intevation.org/mercurial/crew
Replace `(username)` with your BitBucket username and `(repo name)` with the
name of the BitBucket repository, obviously.
Now you can run `hg push` to push any changes you commit locally to your
public BitBucket repository, and `hg pull crew` to grab new changes from the
crew repository.
Build Mercurial
---------------
Make sure you're in your local crew repository, and run:
:::text
make local
This will build Mercurial from the source files. It should finish fairly
quickly. Once that's done, run the tests to make sure everything is working
correctly:
:::text
make tests
Those will take a long time to run. While you wait, move on to the next step.
Create a Virtual Environment for Mercurial Development
------------------------------------------------------
While the test suite is running you're going to make a new virtual environment
to use for testing your changes to Mercurial. First you need to create it, so
open up a new terminal window and run:
:::text
mkvirtualenv hg-dev
You can name it something else if you don't like `hg-dev`. Notice how your
shell prompt now has `(hg-dev)` prepended to it? That's there to remind you
that you're working in that environment.
Creating the environment automatically puts you into it for that shell
session. To get into it in the future you'll use:
:::text
workon hg-dev
Now you need to link the Mercurial libraries you're going to change to this
environment, so you can use it to test your code. Run the following three
commands:
:::text
ln -s (full path to crew)/mercurial $WORKON_HOME/hg-dev/lib/python2.6/site-packages/
ln -s (full path to crew)/hgext $WORKON_HOME/hg-dev/lib/python2.6/site-packages/
ln -s (full path to crew)/hg $WORKON_HOME/hg-dev/bin/
Replace `(full path to crew)` with the *full* path to your local crew
repository, and `hg-dev` with the name of your virtual environment (if you
named it differently than I did).
Why Bother With a Virtual Environment?
--------------------------------------
It's probably the most work in this entire process, so why did I insist you
set it up? Watch this:
:::console
sjl at ecgtheow in ~/src/hg-crew-sjl on default
$ hg --version
Mercurial Distributed SCM (version 1.2.1)
Copyright (C) 2005-2009 Matt Mackall and others
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
sjl at ecgtheow in ~/src/hg-crew-sjl on default
$ workon hg-dev
(hg-dev)
sjl at ecgtheow in ~/src/hg-crew-sjl on default
$ hg --version
Mercurial Distributed SCM (version 7956a823daa3)
Copyright (C) 2005-2009 Matt Mackall and others
This is free software; see the source for copying conditions. There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
(hg-dev)
sjl at ecgtheow in ~/src/hg-crew-sjl on default
$
Look at the version numbers. Notice how they changed?
**You can now use** `workon hg-dev` **to make the** `hg` **command run
Mercurial with your changes!**
This makes it simple to test your work as you go. I keep two terminal windows
open while working on the Mercurial source:
* One is in my local crew repository to diff, commit, etc with the standard
version of Mercurial.
* The other is in a test repository. I've run `workon hg-dev` to switch to my
modified version so I can try out my changes.
Get To Work!
------------
That's it for the initial setup. Now you can start adding all the wonderful
features you have in mind. A simple workflow might go something like this:
1. Open two terminal windows and use `workon hg-dev` in the second one to
switch to the virtual environment.
2. Make some changes to the Mercurial codebase.
3. Test your changes in the second terminal window.
4. Repeat 3 and 4, using the first terminal window to commit to the local
repository as you go.
Once you're finished with your shiny new feature, how do you get it into the
main Mercurial code so we can all benefit from it?
Modify the Test Suite
---------------------
Before you go off and submit a patch, you need to make sure it works with the
current tests. You can run the tests by going to the repository and using:
:::text
cd tests
python run-tests.py
It's going to take a while, just like before. If you changed something that
modifies the output of a command it will probably break some of the existing
tests. That's alright, but you'll need to fix them to reflect your changes.
The simplest way to do this is to use the `--interactive` flag:
:::text
python run-tests.py --interactive
Using `--interactive` will prompt you each time a test fails and ask if you
want to accept the new output as the "correct" output. This makes it simple to
update the existing tests to take your changes into account.
Obviously you should **only accept these updates if they make sense**. Pay
attention to the output and make sure you didn't accidentally break something!
Add to the Test Suite
----------------------
If you've implemented an entirely new feature (as opposed to just modifying an
existing one) you should add some tests of your own. This will make sure no
one else will inadvertently break whatever you've added.
There's a nice [guide][test-guide] to this on the Mercurial site. Follow it to
add some tests for your changes.
From what I've heard it's preferable to append to an existing set of tests (if
it makes sense) instead of adding a brand new test file -- the tests run
pretty slowly and adding new files make them even slower.
[test-guide]: http://www.selenic.com/mercurial/wiki/WritingTests#Writing_a_shell_script_test
Email Your Patches to the Mailing List
--------------------------------------
You've finally got your code working and updated the tests. It's time to share
your changes with the rest of the Mercurial developers.
If you want your patches to get accepted, you should take the time to read the
[guide to contributing changes][] and the [guide to making successful
patches][] on the Mercurial site. They're short but contain most of what you
need to know.
[guide to contributing changes]: http://www.selenic.com/mercurial/wiki/ContributingChanges
[guide to making successful patches]: http://www.selenic.com/mercurial/wiki/SuccessfulPatch
I prefer to use the [patchbomb][] extension to email the patches because it
takes care of the formatting for me. To enable and configure it you'll need to
make some additions to your `~/.hgrc` file:
:::ini
[extensions]
hgext.patchbomb =
[email]
method = smtp from = Your Name
[smtp]
host = smtp.youremailhost.com username = yourusername tls = True
You'll need to tweak those settings with your own email address, mail server,
and so on. Once that's done, you can have patchbomb package up your changes
and email them out:
:::text
hg email --rev (your first revision):(your last revision)
The command will guide you through filling out some more information, and then
send out the patches. `hg help email` has a lot more information on how to use
it.
I usually email them to myself first just in case I mess up a revision number
and email six thousand changesets. Flooding my own inbox is much better than
flooding the list's.
[patchbomb]: http://www.selenic.com/mercurial/wiki/PatchbombExtension
That's It, Now Go Contribute!
-----------------------------
That's about the extent of my knowledge on contributing to Mercurial. As I
said before, I've only done one patch so far, but I wanted to write this while
everything about setting up the environment was fresh in my mind.
If any of the other Mercurial developers would like to chime in and suggest
corrections or additions -- or if anyone has any questions -- I'll be happy to
update the post. I hope it's helpful!

Apple Store discontinues support for iOS 11 devices - Gizchina.com
by Efe UdinApple Store discontinues support for iOS 11 devices
3 (60%) 2 votes
If your Apple device is still running on iOS 11, then its time to upgrade to iOS 12 at least. Technically, we all need the App Store support for our devices to work in full throttle. We need the App Store to either get new apps or upgrade older apps. Now, recent reports show that the Apple Store has discontinued its support for iOS 11 devices.
Since May this year, the Store applications have focused on improvements and performance enhancements. But it’s worth noting that Apple has quietly removed support for the iOS 11 system, and now its Store app supports iOS 12 systems at the minimum. In addition to the inability to download apps, users who already have the app will also need to upgrade to iOS 12 and above to open the Apple Store.
Apple Store app allows you to purchase the latest Apple products and accessories in a more personalized way. You get recommendations based on the Apple products you own and you also find out which accessories are compatible with your device. In addition, users can easily upgrade from their current devices to a new iPhone device (with terms and conditions of course). Furthermore, the Store App allows users to track orders anytime, anywhere, sign up for an interactive course in the store and even use Apple Pay to checkout from your iPhone.

Actions, Resources, and Condition Keys for Amazon Redshift
Amazon Redshift (service prefix: redshift
) provides the following service-specific resources, actions, and condition context
keys for use in IAM permission policies.

Topics
Actions Defined by Amazon Redshift
You can specify the following actions in the Action
element of an IAM policy statement. Use policies to grant permissions to perform
an operation in AWS. When you use an action in a policy, you usually allow or
deny access to the API operation or CLI command with the same name. However,
in some cases, a single action controls access to more than one operation. Alternatively,
some operations require several different actions.
The Resource column indicates whether each action supports resource-level permissions. If
there is no value for this column, you must specify all resources ("*") in the
Resource
element of your policy statement. If the column includes a resource type, then
you can specify an ARN of that type in a statement with that action. Required
resources are indicated in the table with an asterisk (*). If you specify a resource-level
permission ARN in a statement using this action, then it must be of this type.
Some actions support multiple resource types. If the resource type is optional (not
indicated as required), then you can choose to use one but not the other.

Ripple Price Analysis: XRP Goes Back Up To $0.23, Can Christmas Come Earlier?
by Yaz SheikhSummary
- XRP has seen an increase of 4.25% this week as it reaches $0.23.
- The cryptocurrency broke above a steep descending channel that was apparent in November.
- It continues to remain above the strong 3000 SAT support against BTC.
Key Support & Resistance Levels
XRP/USD
Support: $0.2150, $0.20, $0.1850
Resistance: $0.2345, $0.2520, $0.27
XRP/BTC:
Support: 3000 SAT, 2900 SAT, 22853 SAT
Resistance: 3200 SAT, 3325 SAT, 3500 SAT
XRP/USD: A Break Above The Descending Price Channel
The daily chart shows XRP bouncing from the strong support at $0.2150 toward the start of December. The cryptocurrency had been trapped within a steep descending price channel for the entire period of November and broke above this after rebounding at $0.2150.
XRP now faces strong resistance at $0.2345 and must break above $0.24 to see an intermediate bullish run. The support at $0.2150 can be expected to hold moving forward, but a break below would turn the market bearish.
XRP Short Term Price Prediction
If the buyers continue to push XRP above $0.2345, immediate higher resistance is expected at $0.24. Above this, resistance is located at $0.2520, $26.50 (100-days EMA), and $0.27 (bearish .618 Fib Retracement). On the other hand, if the sellers push the market lower, support is expected at $0.215. Beneath this, support lies at $0.205, $0.20, and $0.185.
The RSI is trading at the 50 level which shows indecision within the market. However, the Stochastic RSI is in overbought conditions and is primed for a bearish crossover signal which would send the market lower.
XRP/BTC: Stron Above 3000 SAT
Against BTC, XRP continues to remain above the 3000 SAT support as it trades at 3050 SAT.
For the cryptocurrency to turn bullish against BTC, XRP must break above the resistance at 3325 SAT (November highs). If it was to fall beneath the 3000 SAT support, the market would be considered as bearish.
XRP Short Term Price Prediction
Looking ahead, if the buyers push the market higher we can expect immediate strong resistance at 3115 SAT and 3185 SAT (100-days EMA). Above this, resistance lies at 3325 SAT and 3500 SAT. Alternatively, toward the downside, initial support lies at 3000 SAT. Beneath this, support lies at 2900 SAT (.618 Fib Retracement), 2850 SAT, and 2752 SAT.
The RSI has poked above the 50 level to show the bulls are weakly in charge of the momentum. Furthermore, the Stocahstic RSI recently produced a bullish crossover signal which helped XRP bounce higher from the 3000 SAT support.

I am a moderate who agrees with certain views from each party. However, both parties have strayed so far to the extremes that I don't feel like I have a real choice anymore, and I know there are many other people who feel the same way. I've found in my relatively short lifetime that when two sides are very far apart, 80% of the time the best course of action is somewhere in between. Right now, the loudest sides of both parties drown out any calls from moderates to have civil dialogue and actually create compromises. There are many reasons why this has happened (media and social media bubbles on both sides, the current primary system weeding out moderates, etc...), but one of the primary factors is partisan gerrymandering leading to non-competitive districts. This independent redistricting commission gives me hope that it's possible to make non-partisan districts that are truly competitive and where each citizen's vote has the same impact no matter where they reside. I'm a firm believer in the statement "citizens should choose their representatives, not the other way around," and this commission, if run correctly, is a good step in the right direction for this state. It's one of the few ways I've seen available for moderate citizens like me to be involved in a meaningful way, and I would be honored to be a part of this effort. There are certainly other steps that would need to be taken to help raise the bar of dialogue, but this is a step in the right direction.
I would act as a check to any extremes from both parties. My main focus would be to create districts that are fair for all citizens, regardless of party. I've spent years managing ~30 employees at a drilling company, and I've also started my own business. Both experiences have trained me to be patient, listen more, and then find the best and fairest solution moving forward. There are many times when friends or family of a particular party complain about the other side, and while I may agree with their points, I'll often act as the Devil's advocate for the opposite party. I feel very strongly that the vast majority of people are reasonable when they're not yelling or getting yelled at, and it's this kind of civil dialogue that I will help promote if I'm on the commission.
I'm an engineer by training and am very comfortable with numbers and fact-based problem solving. I often make spreadsheets for my own use, like with analyzing real estate deals, budgeting/saving, projecting sales for a new product, and many other situations. I use these spreadsheets and the resulting information to guide personal and business decisions, not the other way around.

Char is a primitive type for storing and processing single 16-bit Unicode characters. A char literal is a single character enclosed in single quote marks like: 'A', 'b', '8'.
Some features of this data type:
There are some examples of characters:
char a = 'a'; // the 'a' character
char b = 'a' + 1; // the 'b' character
char d = 'b' + 2; // the 'd' character
char ch1 = 101; // the 'e' character
char ch2 = '\u0040'; // the '@' character
If you'd like to find the code of a character, see the Unicode table.
Remember:
char ch1 = '1'; // the character '1'
char ch2 = 1; // it's another character from the unicode table, it’s not the same as '1'
Some characters are used to control computer devices. They are known as the escape sequences or control sequences. They consists of more than one element, but they are considered as a single character.
The most widely used escape sequences:
See the following code example:
System.out.print('\t'); // make a tab
System.out.print('a'); // prints 'a'
System.out.print('\n'); // go to the new line
System.out.print('c'); // prints 'c'
The output:
a
c
All five arithmetic operations ( +, -, *, /, %) are admissible for characters. These operations are performed on the codes of the characters:
char b = 'a' + 1; // in the unicode table the next after 'a' is 'b'
char zero = 48; // '0'
char one = '0' + 1; // in the unicode table the next after '0' is '1'
char ch = '1' + '2'; // the result is 'c', not '3' because the operation sums codes
The class Character has some useful methods for processing characters. Some of them are given below:
Let's see an examples for the listed methods:
boolean isDigit = Character.isDigit('1'); // true
boolean isLetter = Character.isLetter('4'); // false
boolean isLetterOfDigit = Character.isLetterOrDigit('E'); // true
boolean isUpperCase = Character.isUpperCase('A'); // true
boolean isLowerCase = Character.isLowerCase('1'); // false
char upperCaseA = Character.toUpperCase('a');
The class contains many other methods, see here.
