• How to get a stable, snappy UI using threads?

  - by Thomas Ahle

  I recently watching this video on Google Chrome with great interest. It explains that Google Chrome uses one thread for IO, one for opening files and one for intermodule communication. I think I may be able to use something similar for my own - currently quite messy - application. I wondered if there were any good articles on best-practices or patterns for such threaded divisions of tasks?

• Is there a Javascript cron implementation somewhere that I'm missing?

  - by user173491

  I'm aware of timing issues in Javascript, how its not exact/off by milliseconds etc, but I need something to at least attempt to do browser-based scheduling. In terms of features, I'm thinking something along the lines of scheduling patterns described here: http://www.sauronsoftware.it/projects/cron4j/manual.php#p02 Anything out there? I've done google searches and haven't found any implementation worth nothing.

• When knowledge of "multithreading" is specified in a C++ job description, what is the expectation?

  - by Vaibhav Khattri

  I understand it should cover threading primitives (mutex, semaphore, condition variables etc.) plus design patterns (such as those specified in POSA2). But what's more? Every project has its own multithreading scenarios and one may have not dealt with those that the job is expecting?. So how does one build their knowledge and prove that they have the ability?

• Table in DB for generating primary keys?

  - by Sapphire

  Do you ever use a separate table for "generating" artificial primary keys for DB (and why)? What I mean is to have a table with two columns, table name and current ID - with which you could get new "ID" for some table by simply locking the row with that table name, getting the current value of the key, increment it by one, and unlock the row. Why would you prefer this over standard integer identity column? P.S. The "idea" is from Fowlers Patterns of Enterprise Application Architecture, btw...

• a good resource or book for architecting object-oriented software

  - by Ygam

  I have looked at a couple of books and all I have looked at were just discussing the technicalities of OOP. By technicalities I mean, here's a concept, here's some code, now get working. I have yet to see a book that discusses the architectural process, what are the ways of doing this, why doing this is bad, how to actually incorporate design patterns in a real-world project, etc. Can you recommend a good resource or book? I am mainly programming with PHP but a language-agnostic book/resource would do :)

What would be the optimum way of doing this in Perl across all the platforms? On Windows, xcopy is one such solution. On unix platforms, is there a way to do this in Perl?

• Real World Examples of read-write in concurrent software

  - by Richard Fabian

  I'm looking for real world examples of needing read and write access to the same value in concurrent systems. In my opinion, many semaphores or locks are present because there's no known alternative (to the implementer,) but do you know of any patterns where mutexes seem to be a requirement? In a way I'm asking for candidates for the standard set of HARD problems for concurrent software in the real world.

• python copytree with negated ignore pattern

  - by Chris H

  I'm trying to use python to copy a tree of files/directories. is it possible to use copytree to copy everything that ends in foo? There is an ignore_patterns patterns function, can I give it a negated regular expression? Are they supported in python? eg. copytree(src, dest, False, ignore_pattern('!*.foo')) Where ! means NOT anything that ends in foo. thanks.

• I'm still learning OOP. Any tips on staying unbiased and pragmatic?

  - by marcdev

  I keep reading about defficiencies and issues with languages. Specifically, I'm learning PHP and Javascript, but I see it everywhere. This question arose while reading Javascript: The Good Parts and PHP Objects, Patterns and Practice. While understanding and avoiding easy pitfalls, is there a way I can learn the fundamentals of OOP and discover solid programming practices without overlooking important areas (or simply becoming jaded)? I'm sure I'll have plenty of opportunity to learn from mistakes!

• CHKDSK error code 766f6c756d652e63 3f1

  - by BenjiWiebe

  On a Windows 7 computer, running chkdsk /r /f C: in repair mode, it gives the error, Unspecified error 766f6c756d652e63 3f1. or something like that. I have tried the following: uninstalling all antivirus software scanning with MalwareByte's Anti-Malware doing a Disk Cleanup running Disk Defrag booting TRK and running fsck -t ntfs (gives error Unsupported case. and not implemented). I have also tried a System Restore, but there is a Temporary Internet file that appears to be in all restore points, and that file must be corrupted or something, because System Restore always grinds to a halt when it gets to that file. What should I try next? Thanks in advance.
