  • Best Ruby Git library?

    - by Jeff Welling
    Which is the best Git library in Ruby to use? Git, Grit, Rugged, Other? Background: I'm the current maintainer of TicGit-ng which is a distributed offline ticket system built on git, and I've read and heard over and over again that Grit is the one I should use because it supersedes the Git gem, but there seems to be either a lack of documentation or a lack of features because myself and others have failed in trying to switch from the deprecated-but-functional Git to the newer Grit gem.

  • Printing PowerPoint slides in black and white

    - by John Paul Cook
    When I do SQL Server training, sometimes students want to print all of the PowerPoint slides and use them for note taking during class. For such purposes, the background is usually better off being suppressed. This is most efficiently done by changing Print Settings as shown below: Personally I recommend that people take notes directly in the slides instead of printing them. PowerPoint has a notes area. If you do want to print slides and notes, once again use the Print Settings to specify this:...(read more)

  • Import FBX with multiple meshes into UDK

    - by Tom
    I used this script to generate a few buildings that I was hoping to import into UDK. Each building is made of about 1000 separate objects. When I export a building as FBX and import the file into UDK it breaks it up into its individual objects again, so I was wondering how I would avoid this. Whether there was a tool to combine all of the objects into one mesh automatically before exporting or if I could prevent UDK from breaking them upon import.

  • SQL Azure Security: DoS Part II

    - by Herve Roggero
    Ah!  When you shoot yourself in the foot... a few times... it hurts! That's what I did on Sunday, to learn more about the behavior of the SQL Azure Denial Of Service prevention feature. This article is a short follow up to my last post on this feature. In this post, I will outline some of the lessons learned that were the result of testing the behavior of SQL Azure from two machines. From the standpoint of SQL Azure, they look like one machine since they are behind a NAT. All logins affected The first thing to note is that all the logins are affected. If you lock yourself out to a specific database, none of the logins will work on that database. In fact the database size becomes "--" in the SQL Azure Portal.   Less than 100 sessions I was able to see 50+ sessions being made in SQL Azure (by looking at sys.dm_exec_sessions) before being locked out. The the DoS feature appears to be triggered in part by the number of open sessions. I could not determine if the lockout is triggered by the speed at which connection requests are made however.   Other Databases Unaffected This was interesting... the DoS feature works at the database level. Other databases were available for me to use.   Just Wait Initially I thought that going through SQL Azure and connecting from there would reset the database and allow me to connect again. Unfortunately this doesn't seem to be the case. You will have to wait. And the more you lock yourself out, the more you will have to wait... The first time the database became available again within 30 seconds or so; the second time within 2-3 minutes and the third time... within 2-3 hours...   Successful Logins The DoS feature appears to engage only for valid logins. If you have a login failure, it doesn't seem to count. I ran a test with over 100 login failures without being locked.

  • How do I get an Canon Pixma MP150 to print?

    - by Radu Erdei
    I succesfully installed my Canon Pixma MP150 printer (and scanner) in Ubuntu 12.04, made it the default printer, but i cannot print anything. Watching the printing queue, i see that the printer receives my documents but just for a few seconds after which the queue gets empty without anything getting actually printed. I tried to print from large pdf's to quite tiny txt files. I reinstalled the printer from cups web-based interface (127.0.0.1:631) but again, no luck. Any ideea on the matter?

    - by Heihachi
    When i am hitting Super + W and choosing one of active window it opens. But when i am mazimizing another minimized window i am getting blank black window, if i minimize then maximize it again it works. Tried 340.24 drivers - but they are totally unusable because of interface corruption in firefox, thunderbird, libreoffice. 331.89 seems stable except this annoying black window.

  • Criteria for selecting timeout value?

    - by stijn
    Situation: a piece of software reads frames of data from a file in a seperate thread and puts it on a queue, emptied by another thread. That second thread periodically checks on the queue and fails rather gracefully, by showing an error message stating the read timed out, if no data is available within a certain amount of time. Initially this timeout was set to 200mSec. There was no real reasoning behind that constant though, but it worked fine. We measured on a couple of machines and for large data frames, larger than what would be used by customers, a read took like 20mSec whith no other load on the machine. However one customer now gets timeout errors now and then (on the second try all is fine, probably the file is in cache or the virus scanner leaves it alone). The programmers are like 'well, yeah, but that customer's machine is full of cruft, virus scanners, tons of unneeded background processes etc'. Of course the customer is like 'hey this should just work, shouldn't it'? While the programers have a point, since the software is heavy enough to validate the need for a dedicated machine, that does not make the customer happy. Increasing the timeout to 2 seconds, for example, solves the problem. But I'd like to make a proper decision now instead of just randomly pick some magic constant that is probably ok in 99% of cases. What criteria should be used for that? We could just pick a large number, but that feels wrong. (and then we end up with a program that has the horrible bahaviour of hanging when trying to read from a disconnected drive for instance, whereas we'd rather make it show an error right away). Or we could make the timeout value a user setting, but then we need to ducument it clearly and even then not all customers are tech savy enough to really understand what it does. Or we could try and wait until another customer reports timeouts and increase the value again. And again. Until we find something ok for 99.99% of the cases.. Any good practice for this type of situation?

  • Ubuntu 13.10 upgraded from 13.04 issues

    - by Andrew Sadach
    The keyboard stopped working after a while, I started using 13.04 again VIA USB because I am waiting for the keyboard issues that 13.10 has to get an update. 13.04 had tons of issues I didn't care about because most of it worked. Now almost none of it works. There's even a huge amount of graphical errors. Others have had these issues I've noticed while looking at the similar questions area next to this text box, but my question is can I downgrade 13.10 to 13.04?

  • 3 tips for SQL Azure connection perfection

    - by Richard Mitchell
    One of my main annoyances when dealing with SQL Azure is of course the occasional connection problems that communicating to a cloud database entails. If you're used to programming against a locally hosted SQL Server box this can be quite a change and annoying like you wouldn't believe. So after hitting the problem again in http://cloudservices.red-gate.com  I thought I'd write a little post to remind myself how I've got it working, I don't say it's right but at least "it works on my machine" Tip...(read more)

  • Windows Server 2003 network boogey men every DBA should know

    - by merrillaldrich
    Recently I was again visited by my old friends TCP Chimney and SynAttackProtect . (Yeah, sometimes I feel like I mostly blog about 5-year old problems, but many of us as DBA's have to work on older versions or older systems, and so repeat older problems :-). This has been written about before, but as I BinGoogled around I noticed you are more likely to find the documents if you search for the cause, and not the symptoms. Most people who face a problem, of course, know the symptoms but not the cause....(read more)

  • Is it normal to think about a design problem for days with no code written? [closed]

    - by Kim Jong Woo
    Sometimes I stare blankly into space or sketch ideas and write some pseudo codes on paper. Then I scratch it out and start again, then when I think I have the correct solution for the problem I begin writing the code. Is it normal to think for days without writing any code? Is this a sign that I am approaching the problem entirely wrong? It makes me nervous to not getting any tangible code written in my IDE.

  • Can't set music library in Banshee

    - by user1783674
    Recently I noticed that my music doesn't get copied to my music folder when I open files in Banshee and drag them to the library. I opened preferences and the music library folder drop down was empty. I set it back to my music library and tried again: still didn't work. My preferences shows no music folder and I tried setting it to several other folders, neither would stay selected after closing the preferences. What's going on here? Thanks.
