I am trying to take a look at the status of r7rs large but I cannot find any information
in scheme reports page, etc, just a talk from 2013. I searched around with google without success as well.
Is it still alive?
Where can I find information?
What would be the tentative date?
What is the progress at this point?
Thanks.
You can read about the R7RS process on the R7RS working group wiki. R7RS-large is listed under the "Working Group 2" section of the front page.
In particular, look through the StandardDocket and ConsentDocket sections. Standard docket is for stuff that's under discussion (and eventual voting). Consent docket is for generally-uncontroversial stuff that's likely to get into R7RS-large without having to be voted on.
There is no firm timeline that I am aware of (though I'm not part of the working group and do not speak for them). The standard docket is quite long, though, and they will have to process through most/all of it before you have anything that you can call R7RS-large.

I just started my college "adventures", and one of them is subject called operating systems. I must admit that the subject is the most boring ever. Last week, we got our first homework, and i do not know what to do as this is the first time ever i come up with Windows API functions or this topic in general. The task is very simple, we need to write very basic code in C that shows how does GetCurrentThread() work!!!???? I tried looking for solution online, but I could not find anything and our professor is not doing anything to help us. I found the use of functions like GetCurrentThreadID() but that is not what i need. Can somebody write simple program ( 20-30 lines of code ) which contains the use of this function (in C)?
Operating systems courses tend to suck because they take the simplest of concepts and try to make them convoluted.
Documentation for the GetCurrentThread () function is
https://learn.microsoft.com/en-us/windows/desktop/api/processthreadsapi/nf-processthreadsapi-getcurrentthread
What it does not explain is that the return value for the function is a "handle." Windoze uses handles somewhat as pointers to objects but where you cannot access the object directly.
So you call GetCurrent() thread and it returns a "Handle to the Thread." That handle can then be used to do things with the thread.
Here are the things you can do:
https://learn.microsoft.com/en-us/windows/desktop/ProcThread/process-and-thread-functions
Some of these function pages have short examples.
So you could do:
print ("Thread ID: %d\n", GetThreadID (GetCurrentThread())) ;
and have the ID of the current thread.

When running UserMailer.new.perform, my mailer is sent and I get an email almost right away, but when I use UserMailer.perform_async, it spits back an object number and I never receive an email.
Can someone please tell me why this is happening and what the difference between these two methods are?

I'm trying to write a small dictionary Ruby app where I can look up existing entries, add and remove entries (ALL ENTRIES ARE PUT INTO A HASH). So right now I'm creating a Dictionary class and I'm not quite sure what exactly should be 'initialized' method.
I'm still pretty new to Ruby, so if someone could explain what should be initialized at the beginning of a class I'd be extremely grateful.
How do you know what to initialize?
Time and experience. In general, #new should:
Initialize instance variables.
Configure any object defaults.
Register itself with observers.
Housekeeping tasks needed to reach a minimal "ready" state.
Sometimes an object needs to do a lot more work to be "ready" (whatever that means for your class), and #new can just as easily do too little as too much. Finding the right balance for your application is what matters, so feel free to open new questions here or on Code Review Stack Exchange with more concrete questions and some actual code.

What naming conventions do you use when creating work items in your task/bug tracking tools?
For example:
Do you prefix the items with an area/subject?
How do you begin scenarios/use cases? E.g., "The department manager can..."
How do you make it easier to detect duplicates?
Your project management, bug tracking and time management (if different from the pm tool) should follow the same pattern, no matter what the pattern is. I usually like to do a top down approach: project-application-page (for example: Amazon-Order Entry-Confirmation Page) - if the project/task management, bug and time management all follow the same pattern then you can track tasks to open issues to time spent easily. After the page you enter a short descriptive text of the issue. In the description area, you need to state:
environment (OS/browser)
version being tested
server environment (dev, QA, or production)
the bug (screen captures help greatly)
the expected results (what you expected to happen)
level of issue (show stopper to nice-to-have-but-will-never-get-done)

Some of the features I think it must include are:
Print Entire Solution
Ability to print line numbers
Proper choice of coding font and size to improve readability
Nice Header Information
Ability to print regions collapsed
Couple feature additions:
Automatically insert page breaks
after methods/classes
Keep long lines readable (nearly all
current implementations are broken)
Note: There are many reasons to need to print code... One very good one is escrow.
I use PrettyCode.Print for .NET. It does everything on your list, and more. (I use it for printing code excerpts for copyright registration paperwork, which is similar to your escrow case.)
It is a little slow to open a really big solution, but not unbearably so, and the output quality is excellent.
Try StarPrint's VSNETcodePrint
