  • How does Python compile some its code in C?

    - by Howcan
    I read that some constructs of Python are more efficient because they are compiled in C. https://wiki.python.org/moin/PythonSpeed/PerformanceTips Some of the examples used were map() and filter(). I was wondering how Python is able to do this? It's generally interpreted, so how does some of the code get compiled while another is interpreted - and in a different language? Why not just compile the whole thing?

  • New SQL Server 2012 per core licensing – Thank you Microsoft

    - by jchang
    Many of us have probably seen the new SQL Server 2012 per core licensing, with Enterprise Edition at $6,874 per core super ceding the $27,495 per socket of SQL Server 2008 R2 (discounted to $19,188 for 4-way and $23,370 for 2-way in TPC benchmark reports) with Software Assurance at $6,874 per processor? Datacenter was $57,498 per processor, so the new per-core licensing puts 2012 EE on par with 2008R2 DC, at 8-cores per socket. This is a significant increase for EE licensing on the 2-way Xeon 5600...(read more)

  • Webdav stops working after a few seconds

    - by user214885
    With Ubuntu 13.10, I connect to two different OwnCloud installations and can browse for only a few seconds before it freezes the connection and stops working. When I try to reinstate the connection it fails to even ask for the password (Ubuntu was told to forget the password). I did check the webdav connection through Firefox on two computers and ES File Explorer on android. I know that this isn't a webdav problem and don't know what is happening in Ubuntu to stop being able to read the connection.

  • How to calculate the size of a project in the days-person unit of measurement?

    - by Will Marcouiller
    Once in a while I have read here and there the size of a project expressed in a matter of days-person or person-day. I may understand what this means, but I don't know on what do people base themselves to calculate it. What are the variables considered into this calculation? How these variables are used in the calculation formula? Otherwise, how to estimate it grossly, when something is missing from the formula's variables? Thanks! =)

  • PASS Summit 2012 Women In Technology Luncheon

    - by AllenMWhite
    My final stint at the Summit Blogger's Table(tm) is for the annual WIT luncheon. I do appreciate the honor that PASS conferred on me by inviting me to the "table" for the event, it's been a lot of fun (even if there were some moments that weren't.) Newly-elected board member Wendy Pastrick is the MC for this year's luncheon, and the panel consists of Stefanie Higgins, Denise McInerny, Kevin Kline, Jen Stirrup and Kendra Little. I'm pleased to say that I know each one of them except Stefanie Higgins,...(read more)

  • Efficient, partial, point-in-time database restores

    - by GavinPayneUK
    This article is about a situation that many of us could describe the theoretical approach to solving, but then struggle to understand why SQL Server wasn’t following that theoretical approach when you tried it for real. Earlier this week, I had a client ask about the best way to perform: a partial database restore, 1 of 1300 filegroups; to a specific point in time; using a differential backup, and therefore; without restoring each transaction log backup taken since the full backup. The last point...(read more)

  • What would another Ubuntu user's default font be?

    - by Gonzoza
    If I send an email from, say, Thunderbird, and have "Helvetica/Arial" set as my default outgoing font, then my assumption is that most of the world will read that email in Helvetica (Apple) or Arial (Windows). But what if I send that email to another Ubuntu user who does not have the MS core fonts installed? What will the email's font default to? Would Ubuntu override it with something like sans-serif, perhaps?

  • Cell Transitions in Excel 2013 Preview–Fixed

    - by simonsabin
    If you’ve downloaded Excel 2013 and been working with it you may have noticed the new cell transition feature. Not sure why they put it in, it feels a bit like the aero interface which I understand has been dropped in windows 8. What you may have found is that the transition is buggy, Excel hangs, of the transition is jumpy. Well I found the fix on http://answers.microsoft.com/en-us/office/forum/office_home-excel/hardware-acceleration-problem-with-excel-2013/894da202-48c0-4442-a371-955587c1b7c0 For...(read more)

  • SQL Server 2008 R2: StreamInsight changes at RTM: AdvanceTimeSettings

    - by Greg Low
    For those that have worked with the earlier versions of the simulator that Bill Chesnut and I constructed for the Metro content (the Highway Simulator), changes are also required to how AdvanceTimeSettings are specified. The AdapterAdvanceTimeSettings value is now generated by binding an AdvanceTimeGenerationSettings (that is based on your adapter configuration) with an AdvanceTimePolicy setting. public class TollPointInputFactory : ITypedInputAdapterFactory < TollPointInputConfig >, ITypedDeclareAdvanceTimeProperties...(read more)

  • Halloween: Season for Java Embedded Internet of Spooky Things (IoST) (Part 4)

    - by hinkmond
    And now here's the Java code that you'll need to read your ghost sensor on your Raspberry Pi The general idea is that you are using Java code to access the GPIO pin on your Raspberry Pi where the ghost sensor (JFET trasistor) detects minute changes in the electromagnetic field near the Raspberry Pi and will change the GPIO pin to high (+3 volts) when something is detected, otherwise there is no value (ground). Here's that Java code: try { /*** Init GPIO port(s) for input ***/ // Open file handles to GPIO port unexport and export controls FileWriter unexportFile = new FileWriter("/sys/class/gpio/unexport"); FileWriter exportFile = new FileWriter("/sys/class/gpio/export"); for (String gpioChannel : GpioChannels) { System.out.println(gpioChannel); // Reset the port File exportFileCheck = new File("/sys/class/gpio/gpio"+gpioChannel); if (exportFileCheck.exists()) { unexportFile.write(gpioChannel); unexportFile.flush(); } // Set the port for use exportFile.write(gpioChannel); exportFile.flush(); // Open file handle to input/output direction control of port FileWriter directionFile = new FileWriter("/sys/class/gpio/gpio" + gpioChannel + "/direction"); // Set port for input directionFile.write(GPIO_IN); } /*** Read data from each GPIO port ***/ RandomAccessFile[] raf = new RandomAccessFile[GpioChannels.length]; int sleepPeriod = 10; final int MAXBUF = 256; byte[] inBytes = new byte[MAXBUF]; String inLine; int zeroCounter = 0; // Get current timestamp with Calendar() Calendar cal; DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss.SSS"); String dateStr; // Open RandomAccessFile handle to each GPIO port for (int channum=0; channum And, then we just load up our Java SE Embedded app, place each Raspberry Pi with a ghost sensor attached in strategic locations around our Santa Clara office (which apparently is very haunted by ghosts from the Agnews Insane Asylum 1906 earthquake), and watch our analytics for any ghosts. Easy peazy.

  • How to mount a drive for other user than root?

    - by Ondra Žižka
    I've attached a SSD disk though USB. Then: sudo su - mkdir /mnt/hx chown ondra /mnt/hx mount /dev/sdb1 /mnt/hx # It's FAT32 now, but was the same with EXT4 The last command changes dir owner to root. Whenever I create a file in the root dir, I need to be root and root is the owner. Can I set different user as owner of the mounted dir? Or, simply said, ensure that user XY can freely read/write on the drive.

  • Just getting started in Spring and my preference is XML config over annotations. Correct or not?

    - by John Munsch
    After having read through some of the Spring docs my inclination is towards using a XML config file rather than annotations on the classes themselves. My reasoning is that by doing so you avoid tying your POJOs to a particular framework. Based on your experience with Spring, are there any advantages that XML configuration have over an annotation based configuration, and if not what are the disadvantages?

  • No Sync of Files in Android U1 folder

    - by Oldbwl
    My Desktop (Ubuntu 12.10) and Laptop (Win 7) happily sync files. The Ubuntu One folders are perfectly in sync. I have an Asus Transformer with the Ubuntu One app installed. I can read files from the cloud, and they download to a U1 folder. If I edit the files in the Asus (say a sheet in Kingsoft) it appears they never go back to the cloud unless I physically select the file to be uploaded. Is this correct?

  • What does this Express Edition look like, anyhow?

    - by TiborKaraszi
    Chances are that you rarely get to see the Express Edition of SQL Server if you mainly work with servers. This blog post is inspired from a forum discussion where some functionality is missing in SQL Server Management Studio (SSMS) and I suspected that the tools were installed as a Basic installation instead of Complete installation. So how do I check that? Difficult if I don’t have such an install to look at. I’m training this week and have a few spare machines to play with so I went ahead and installed...(read more)

  • Unable to boot windows 8.1 after installing Kubuntu 14.04

    - by user289452
    I just installed Kubuntu 14.04, and I cannot boot into the previously installed Windows 8.1. As I read everywhere, this shouldn't be a problem: Kubuntu should recognize that Windows is there. But every time I start Kubuntu boots without asking anything. Thank you for your answers! UPDATE: I realized that I run a chkdsk on the Windows' partition, and I didn't let it end, so it may be marked as "unclean" as written here: Problem to enter in NTFS partition Still struggling to make it work, though.

    I wanted to create an option in the context menu to set the clicked picture to current desktop background (just like in Windows). I read the the nautilus action help but I couldn't figure it out. This is by far the command I could craft: gsettings set org.gnome.desktop.background picture-uri file://$PWD/ What I need: A command that correctly sets the current image to be the desktop background This command should only appear to the proper files (picture extenstions like .jpg)
