• Protocol Security With PPTP

  - by why

  I find these words in pptp client source : Summary by Peter Mueller PPTP is known to be a faulty protocol. The designers of the protocol, Microsoft, recommend not to use it due to the inherent risks. Lots of people use PPTP anyway due to ease of use, but that doesn't mean it is any less hazardous. The maintainers of PPTP Client and Poptop recommend using OpenVPN (SSL based) or IPSec instead. (Posted on [1]2005-08-10 to the [2]mailing list) But as far as i know, there are many people use PPTP as a VPN, because there is no need to install client on windows, what do you think about pptp ?

• Updating a gridview based on dundas chart callback

  - by Daud

  I have a dundas pie chart which when clicked issues a client callback which updates another chart associated with it. Basically its like a drill down thing. I also want to update my gridview based on the user's selection of the pie. But since the update of chart is being done using dundas client callback I'm unable to rebind my Gridview. Is there any way to do it? .

• How do you determine an acceptable response time for DB requests?

  - by qiq

  According to this discussion of Google App Engine on Hacker News, A DB (read) request takes over 100ms on the datastore. That's insane and unusable for about 90% of applications. How do you determine what is an acceptable response time for a DB read request? I have been using App Engine without noticing any issues with DB responsiveness. But, on the other hand, I'm not sure I would even know what to look for in that regard :)

• Any way to disable specific CPU sleep modes?

  - by Philippe

  I just got a new Toshiba Tecra S11 notebook, which has a Core i5 520M CPU, and it appears to suffer from a well-known problem: a high pitched noise when the CPU is idle. Googling around revealed that this is caused by a specific power-saving mode in the CPU. In most cases, C4 mode is blamed for the noise. So my question is: is it possible to disable C4 mode (or any other "sleep" mode) using some utility or BIOS setting? I don't mind if it hurts battery life. I'd appreciate any advice on this matter. It's driving me crazy.

• Is there a terminal that features sliding like guake and screen spliting like terminator on Linux?

  - by e-satis

  Sliding means I got the terminal always in background and I can call it with a shortcut, and it will slide down from the top of the screen like in Quake (which why the most known terminal implementing it is called guake). Splitting terminal means I can seen in one terminal tab several shells, like with screen or tmux. But I can also take the focus on each part of the terminal by clicking on it, not just with a 4 keys keyboard shortcut. Which terminator let me do. Is there a terminal that features both on Linux ? Even something I can pay for.

• SEAGATE Barracuda 7200.11 HDD not running

  - by Dane411

  After a huge research, I'm stuck at the beggining of getting my HDD data back. Whats happening to me is that in the moment when I plug the power wire to my external 1TB SEAGATE Barracuda 7200.11 ST31000333AS HDD Fw LC15, it makes the sound like it's spinning to almost full speed and then shuts down and spins up again, and so on. It's well known that those HDDs have a bad firmware that someday randomly fails. There are like 2 main problems identified, BSY (busy) state, and LBA0 error. Last time I connected it to power nothing happened, it didnt try to start at all, is it that so called bricked state? I guess my HDDs error is the first one, but I dont really know if what I described is that BSY state or not, neither I know how to check it. How could I know it? Thank you so much!

• How do I install and run Tomcat on port 80 as my only web server? (Rooted Ubuntu box)

  - by gav

  Hi All, tl;dr - I have a rooted linux box that I want to run tomcat on as a server (No Apache Web Server) how would you set this up avoiding common security pitfalls? I've written a Grails App that I want to run on a VPS I rent. The VPS has very little memory and I am using it for the sole purpose of running this application so I don't need the apache web server. This is my first venture into Server administration and I'm sure to fall into some well known traps. Should I use iptables to redirect requests from port 80 to 8080? Should I run tomcat as root or as it's own user? What configuration settings would be good for a low memory system expecting less than 10 concurrent users? Hopefully an easy one for you! Anyone who could link to a tutorial would be a personal hero destined for great things no doubt. Gav

  - by cake

  Hello In my work, I'm developing a Viewer client for a Offshore simulation server, using sockets to send the simulation data from the Simulator to de Viewer. But, the server uses Boost.asio as it's sockets library. As the client uses Qt for it's GUI, I was wondering if there is any problem in using de Qt Networking library for handling the sockets. Is there any compatibility issues? Thanks in advance, and sorry for my bad english.

• Internet Explorer 9 auto "feeling lucky" for gmail bing search

  - by Gareth Jones

  When Im at school and using school computers, i have to use has IE9. When I want to access my gmail, I type in "gmail" in the URL bar, and thus IE9 does a bing search. The page half loads (As in, loads just about every thing but the search results) and then opens my gmail, kinda like google's "i'm feeling lucky". My question is this: Why? IE9 doesn't have the URL of gmail, as i can watch the bing search load, and then the url changes to gmail, and it only happens for Gmail, having tired with searching Google and Facebook in the same method. The computer is running Windows 7 with Windows Aero disabled, and limited account privileges. While its a cool thing, I would like to known what causes it to happen. Thanks

• use of Lsh and Rsh keys in windows 7 calculator

  - by Tom

  Does anyone know the function of the Lsh and Rsh keys in Windows 7 calculator when it is in Programmer's mode. One would think it's meant to shift bits left and right, but that doesn't seem to happen: sometimes nothing happens, other times I get a 'Result not defined' message in the display. Has anyone figured it out yet, is this a known bug? While we're at it, does anyone have suggestions for a good calculator, one with a decent reference guide / user guide (windows help doesn't seem to give any hints on what any of the keys do, in any mode).

• How to set up Aptana Studio 3 with a Bitbucket private repo

  - by Titus

  I have just started playing around with Git and would like to push a personal project to a newly created, private repo on Bitbucket using Aptana Studio 3. I tried to use the Git integration in Aptana but I couldn't figure out where to enter my username and password for Bitbucket anywhere. I tried using the Team > Share Project context menu but that keeps throwing the following message: Warning: Permanently added the RSA host key for IP address '207.223.240.181' to the list of known hosts. Permission denied (publickey). fatal: The remote end hung up unexpectedly I'm pretty sure that's because my repo is private. However, I couldn't find a provision to provide any form of credentials for linking to a private repo. Any ideas?

• XNA/C# Game Settings (Menu?)

  - by PCAddict

  It's my first time trying to make anything really interesting in C# and I was trying to make a simple form or game screen where the user could define a custom resolution/screen ratio etc. or to automatically detect the max screen size/ratio and output? its my first game, so I was wondering if it was possible or if there would be any major issues with such, rather than just setting it to 1366x768 (the resolution of all of my computers). Thanks in advance for any assistance.

• Mac sees mangled filenames from Linux SAMBA share

  - by me2

  Certain filenames in my SAMBA shares from Linux are not getting transmitted properly. It's certain files in certain folders and it doesn't affect all folders or all files within a single folder. I can find no discerning pattern to the mangling but hoping that this is a known problem. No amount of reboot, restart, etc. will fix this problem. The filenames, when they get mangled, all end up in this form: 0JY4B3~H.M4V 0MBS1O~M.M4V 0NKDX9~R.M4V 0O0ZTA~A.M4V These are MPEG4 files. The extension remains intact. Any ideas?

• How to debug high memory usage by registry?

  - by bkr

  I have a windows 2008 r2 server running ADFS2 and some web apps that is having issues with low memory. Digging around I found that the 5.5 GB were being used under Kernel Memory (paged). Further digging with Poolmon, I discovered that the majority of that (5GB+) was being used by CM - configuration manager. Also known as the registry. I'm really now sure how to tell why the registry is using so much memory however, or how to release it? Looking at the physical registry files they don't appear that large. EDIT #1 Using the powershell script @ http://jdhitsolutions.com/blog/2011/05/get-registry-size-and-age/ confirms what I saw looking at the physical registry files, that they're relatively small Computername : (removed) Status : OK CurrentSize : 67 MaximumSize : 2048 FreeSize : 1981 PercentFree : 96.728515625 Created : 4/1/2011 11:38:02 AM Age : 454.23:41:28.2540682

• How do I remove a URL from Google without having to have a Google E-mail Account

  - by PP

  Really simple question. I do not want a Google account. I just want Google to stop making requests every 2 minutes for a URL it should never have known about (apparently Google harvests URLs from search requests as well as private e-mails, not just from actual web pages). But when I search Google help for removing URLs it appears I have to use their "webmaster tools" which require logging into a GMail account! How do I tell Google not to index my URL without becoming a customer? Note: I already return 404 for the URLs in question using a rewrite rule - this appears to make zero difference to the crawler which continually attempts to fetch the page every 2 minutes.

• How could I portably split large backup files over multiple discs?

  - by sourcejedi

  Context: I make backups / archives, primarily of photos. I'm experimenting with Bup, which is designed for backup to hard disk. Basically it creates Git repos which include packfiles of up to 1GB. But I still need last-ditch backups to keep offline and move offsite (and keeping them on read-only media is good too!). What are the options for archiving and splitting large files over several discs like CDs (and reading them back!)? I'd prefer methods which will stay readable in future. are portable e.g. to Windows. have known simple implementations, so I could re-implement them myself if necessary. (Using Bup packs will stretch my robustness budget. So I want to be confident about how other parts of the system would behave). I heard split archives are possible with both ZIP and 7-Zip. Is that right?

• Login sometimes failing immediately after restoring a database

  - by Ian Ringrose

  We have a set of automated tests that restore a database then run some .net code against the database. Sometimes after the database is restored the login from Ado.net fails. If I re-run the test, then the restore and login works OK. The restored database looks OK when viewed with Management Studio. This is only an problem on some machines. We are using SQL server 2008. Is there a known issue with a database restore “returning “ a very short time before the restored database is up and running.

• Biggest Delphi nitpicks

  - by Mason Wheeler

  What sort of minor annoyances do you run into using Delphi? I'm not looking for major issues such as "I want a 64-bit compiler." Just little things that can be easily worked around but still should have been implemented better so you don't have to work around them? Marking this CW. I'm more interested in the answers than the points.
