  • Improve Performance of char.IsWhiteSpace for ASCII inputs in .NET 3.5

    - by Tanzim Saqib
    IsNullOrWhiteSpace is a new method introduced in string class in .NET 4.0. While this is a very useful method in string based processing, I attempted to implement it in .NET 3.5 using char.IsWhiteSpace() . I have found significant performance penalty using this method which I replaced later on, with my version. The following code takes about 20.6074219 seconds in my machine whereas my implementation of char.IsWhiteSpace takes about 1/4 less time 15.8271485 seconds only. In many scenarios ex. string...(read more)

  • Launch 2010 Technical Readiness Unofficial Q&amp;A.

    - by mbcrump
    I had an email from one of my readers about the 2010 Technical Readiness Series. Please read below: Hi Michael, I noticed you blogged a while back that you were going to attend MS 2010 Launch event. I’m going to the session in Seattle on May 27, is it worth it to attend? Also, I’m wondering if they give any free software away like VS2010 Pro? Any decent vendors? Looking forward to hearing back from you. I decided this information would probably benefit several instead of just responding back to the reader. In case you are not aware, MS has a 2010 launch event showing VS2010, Office 2010, SharePoint 2010 and SQL Server 2008R2.  You can sign up for an event here: https://microsoft.crgevents.com/Register2010/Content/Event_Selection.aspx I’ve answered the questions asked below. Q: Is it worth going? A: It is if you have had little or no exposure to the latest 2010 products. Most people are familiar with VS2010, but have not seen SharePoint 2010 Office 2010 or Windows Phone 7. It is designed to get you up to speed very quickly. If you have watched most of the MIX videos and keep up with .NET in general, you will benefit more by having the ability to ask questions.    Q: Did you get any free software? A: No, only demos including: VS2010/Office 2010 – They give you a link to the url where you can download the trial version. Windows 7 Enterprise – You get a DVD with the trial version loaded. Q: Do they give away any cool swag? A: Just a Microsoft T-Shirt (XL). Q: What about the vendor selection? A: At the event that I went to, most vendors were pushing SharePoint products. There wasn’t a lot of variety in the selection. Most vendors were giving away the typical pens, buttons and stickers and trial software. If you have any other questions, feel free to contact me. I will answer and add to this un-official FAQ.

  • How can I keep current with Python coding style?

    - by vartec
    I've been using Python since version 2.2. I do pick up new language constructs like for example with statement or dictionary/set comprehensions. However, I've realized that even though I'm being consistent with PEP-8, for existing constructs I'm using old style, rather than new style (for example except Exception, e instead of except Exception as e). Is there a resource which would have either most current style guide, or even better a list of changes in Python's coding style?

  • Ok to target product names in adwords?

    - by Tom Gullen
    If I have widget company called "Widget Designer" and I have a direct competitor who has "Widgitator Version 5", am I allowed to target a campaign using the literal keywords "Widgitator"? Is this OK? Will they ever find out? Is it bad business? Update I can't really say what the words are, but this is a good example, if my product is called "Chair-o-matic" and it makes chairs, and a competitors is called "Chair Maker 5" can I target the keyword pair "Chair Maker"?

  • Failed 12.04 installation

    - by Rob Sayer
    I tried installing Ubuntu 12.04 today. Not an upgrade, a new installation. It didn't work. My computer specs: Computer: Compaq presario CQ-104CA OS: Windows 7 Home 64 bit CPU: AMD V140 BIOS: latest Graphics: amd m880g with ati mobility radeon hd 4250 Wireless: atheros ar9285 Internal HD:SATA I wasn't connected to the internet at the time ... I know of a number of people who have installed ubuntu unconnected and just updated later. It seemed to go normally until I got to the part where I chose to install dual boot linux/windows. Then, the screen went black and the following test appeared (I left out the [OK]'s): checking battery state starting crash report submission daemon stating cpu interrupts balancing daemon stopping system V runlevel compatibility starting configure network device security stopping configure network device security stopping cold plug devices stopping log initial device creation starting enable remaining boot-time encrypting devices starting configure network device security starting save udev log and update rules stopping save udev log and update rules stopping enable remaining boot-time encrypted block devices checking for running unattended-upgrades acpid: exiting speech-dispatcher disabled: edit /etc/default/speech-disorder At this point, the CD is ejected. Then nothing. If I press the return key, it boots Windows. I don't think that's what's supposed to happen. Thinking the cd media or dvd drive may have been faulty, I downloaded the .iso again and made a bootable USB stick, as per your instructions. This time there was no cryptic crash screen. It just booted windows. I can't find any log files it may have left. Thinking the amd64 version may have been the wrong one, I tried downloading the x86 version. Same thing, both from cd and usb drive. Note I downloaded both files twice. I doubt it was a corrupted d/l. This is supposed to be a simple, transparent install. I went to the time and trouble of looking up my devices and drivers re ubuntu beforehand, and was prepared to do some configuration, though I know someone who has the same wireless device and his worked righted out of the box. But I spent over 3 hours trying to install it with only the above to show for it.

  • Oracle Index Skip Scan

    - by jchang
    There is a feature, called index skip scan that has been in Oracle since version 9i. When I across this, it seemed like a very clever trick, but not a critical capability. More recently, I have been advocating DW on SSD in approrpiate situations, and I am thinking this is now a valuable feature in keeping the number of nonclustered indexes to a minimum. Briefly, suppose we have an index with key columns: Col1 , Col2 , in that order. Obviously, a query with a search argument (SARG) on Col1 can use...(read more)

  • cant connect to internet directly on ubuntu

    - by shubham
    I have dual booted machine windows 7 with ubuntu 12.10. I dont have direct internet access in ubuntu on wired network although direct connection works in windows7. I have to connect through a proxy on ubuntu, which works fine. This is not a ubuntu version related problem as i have been getting it from ubuntu 11.04. I want to know what difference is there in ubuntu and windows 7 which creates such results and how to fix it?

  • Create an ad-hoc connection that looks like a wifi connection from a router

    - by James
    I have a Vizio tablet (running a modified version of Android 2.3.2) which, for some reason or another, refuses to list Windows ad-hoc wifi connections on it's wifi connection screen. It can connect to wifi networks served from a normal router, but the wireless bit of my home router is broken, so I'd like to share the internet connection through my laptop's wifi card until the new router arrives. Is it possible to create an ad-hoc network in Ubuntu that looks like a normal wireless network to my tablet?

  • Intel Centrino Wireless N 1000 doesn't work on a Lenovo Z560

    - by Timetraveler
    I upgraded my Ubuntu 11.04 to 11.10 and my Wifi has stopped working. I have a Lenovo Z560 that has Intel centrino wireless-N 1000. I have searched various threads having similar problems for a solution and have no success. The wlan0 is not even showing up in rfkill. Please help me find a solution. I am giving below the output of various debug commands. Thanks in advance.
