• Cannot access or open Facebook messages [migrated]

  - by Ehsan Mamakani

  I was up to sending a very long message, about 90,000 characters, to a friend, I tried several times but I got an error sending the message. Finally, I think part of my message was sent because I could see the characters in my message list under my friend's name. When I clicked the name to see my whole message it wouldn't load the message. And now I can't access any of my messages and I get this message from Facebook: Sorry, messages are temporarily unavailable. Please try again in a few minutes. How can I get access to my messages and conversations again?

• How to relink user folders in Windows 7

  - by Jonathan

  The short story: Win7 lost track of my user folders location (desktop, my documents, my pictures etc...). They now reside on a different partition. How can I relink these folders? The long story: The way I partition my drives is: C: - SSD drive for Windows and Program Files D: - A large regular hard drive for all my user data The first thing I do after a fresh Win7 install is move my user folders to D:, by right clicking on these folders under C:\users\username\, choosing the Location tab and clicking on Move. I've just completed encryption of D: using TrueCrypt. It shows a lot of warnings before the encryption process, but (hrrmm...) it does not mention the fact that after encryption the data is located on a new drive letter, say E: This broke Win7's links to my special user folders. How can I relink these folders?

• PDF booklet printing

  - by Diego

  I have a Samsung ML-2851nd printer (laser, duplex) When printing booklets from PDF files, what is best? Printing with "standard" Page Scaling from Reader, and selecting Booklet printing from the Printer Properties Using the Booklet Printing option from Reader, and only selecting "Print on Both Sides" in the Printer Properties. If I go with the first option, can I use Page Scaling "None" to get bigger text or will it cause any problems? (Fit to printable area shrinks to 93%, I'm using A4 paper) If I go with the second one, what's the correct setting: "Flip on Long Edge" or "Flip on Short Edge"? Thanks!

• How secure is the encryption used by Microsoft Office 2007?

  - by ericl42

  I've read various articles about Microsoft's Office 2007 encryption and from what I gather 2007 is secure using all default options due to it using AES, and 2000 and 2003 can be configured secure by changing the default algorithm to AES. I was wondering if anyone else has read any other articles or know of any specific vulnerabilities involved with how they implement the encryption. I would like to be able to tell users that they can use this to send semi-sensitive documents as long as they use AES and a strong password. Thanks for the information.

• Mini-ITX board for AM3 Athlon X4 600e processor.

  - by Kamil Zadora

  Hello, I am planning to build a PC to control a robotic platform that I am building (about 50% complete). I need more power than ATOM platform could bring, as the robot will need to do on the fly image processing to work as intended. I was considering using Athlon X4 600e as it is rated 45W Maximum output. Probably underclocked it would go lower than 30-35W. I do not I'am at very long battery life, but the 17Ah, 12V battery should keep it running for few hours. My problem is: motherboard. I am space limited so I am looking for a nice mini-itx AM3 motherboard to match the processor. It is hard to find many tests about power usage of the motherboards itself (for example, when using the same processor on different motherboards, test are usualy done in the opposite matter). Could you provide any motherboard examples or suggest what chipset to look for? Thank you in advance.

• china and gmail attacks

  - by doug

  "We have evidence to suggest that a primary goal of the attackers was accessing the Gmail accounts of Chinese human rights activists. Based on our investigation to date we believe their attack did not achieve that objective. Only two Gmail accounts appear to have been accessed, and that activity was limited to account information (such as the date the account was created) and subject line, rather than the content of emails themselves.” [source] I don't know much about how internet works, but as long the chines gov has access to the chines internet providers servers, why do they need to hack gmail accounts? I assume that i don't understand how submitting/writing a message(from user to gmail servers) works, in order to be sent later to the other email address. Who can tell me how submitting a message to a web form works?

• Loggon to Internet Hotspot from within Linux Terminal

  - by Saif Bechan

  For internet I use a local Hotspot service. I have internet when I start my browser and fill in my username and password. This stays as long as I do not shut down my PC for a while. I run some virtual machines, centos, debian, from the command line. I run these just for small test purposes, nothing special, and security is not an issue for me at all. I want to have these VM's connect directly to the hotspot if this is possible. So they each have there own IP. I have enough hotspot accounts to do so. I can do this with a bridged connection in VMware which works find with a GUI. But I run these OS's from the command line. I only need to know a way how to get the hotspot to validate my credentials. Is there a way of doing this without having a gui.

• Remote desktop sessions - Unwanted automatic log off after period of time

  - by alex

  I'm having an issue whenever I connect to any of our servers via RDP - After a certain period of time, it seems to close these sessions, closing all the applications i had open etc... This is particularly annoying if I am running a long process - for example, copying a file - it cuts it off... I then re-connect via RDP, and it effectively loads a new session. Is this set somewhere in Group Policy? Or somewhere else? This is happening on Windows 2008 (it may also be on our 2003 servers, although I haven't noticed...)

• Is Joel Test really a good gauging tool?

  - by henry

  I just learned about Joel Test. I have been computer programmer for 22 years, but somehow never heard about it before. I consider my best job so far to be this small investment managing company with 30 employees and only 3 people in IT department. I am no longer with them but I had being working there for 5 years – my longest streak with any given company. To my surprise they scored extremely poor on Joel Test. The only two questions I would answer “yes” are #4: Do you have a bug database? And #9: Do you use the best tools money can buy? Everything else is either “sometimes” or straight “no”. Here is what I liked about the company however: a) Good pay, they bragged about it to my face and I bragged about it to their face, so it was almost like a family environment. b) I always knew big picture. When writing a code to solve particular problem there were no ambiguity about the business nature of that problem. Even though we did not always had written specs we could ask business users a question anytime, often yelling it across the floor. I could even talk to executives any time I felt like doing it: no appointment necessary. c) Immediate feedback. Once we implement a solution and make business users happy they immediately let us know that, we (programmers) become heroes of the moment. d) No red tape. I could always buy any tools I deem necessary, and design solutions the way my professional judgment dictates. e) Flexibility. If I had mid-day dental appointment that is near my house rather than near the office, I would send email to the company: "FYI: I work from home today". As long as one of 3 IT guys was on the floor (to help traders in case their monitors go dark) they did not care where 2 others are. So the question thus becomes how valuable Joel Test is? Why bother with it?

• Getting into driver development for linux [closed]

  - by user1103966

  Right now, I've been learning about writing device-drivers for linux 3.2 kernel for about 2 months. So far I have been able program simple char drivers that only read and write to a fictitious dev structure like a file, but now I'm moving to more advance concepts. The new material I've learned about includes I/O port manipulation, memory management, and interrupts. I feel that I have a basic understanding of overall driver operation but, there is still so much that I don't know. My question is this, given that I have the basic theory of how to write a dev-driver for a piece of hardware ... how long would it take to actually develop the skills of writing actual software that companies would want to employ? I plan on getting involved in an open-source project and building a portfolio. Also what type of beginner drivers could I write for hardware that would best help me develop my skills? I was thinking that taking on a project where I design my own key logger would easy and a good assignment to help me understand how IO ports and interrupts are used. I may want to eventually specialize in writing software for video cards or network devices though these devices seem beyond my understanding at the moment. Thanks for any help

• Tale of an Encrypted SSIS Package in msdb and a Lost Password

  - by Argenis

    Yesterday a Developer at work asked for a copy of an SSIS package in Production so he could work on it (please, dear Reader – withhold judgment on Source Control – I know!). I logged on to the SSIS instance, and when I went to export the package… Oops. I didn’t have that password. The DBA who uploaded the package to Production is long gone; my fellow DBA had no idea either - and the Devs returned a cricket sound when queried. So I posed the obligatory question on #SQLHelp and a bunch of folks jumped in – some to help and some to make fun of me (thanks, @SQLSoldier @crummel4 @maryarcia and @sqljoe). I tried their suggestions to no avail…even ran some queries to see if I could figure out how to extract the package XML from the system tables in msdb:   SELECT CAST(CAST(p.packagedata AS varbinary(max)) AS varchar(max)) FROM msdb.dbo.sysssispackages p WHERE p.name = 'LePackage'   This just returned a bunch of XML with encrypted data on it:  I knew there was a job in SQL Agent scheduled to execute the package, and when I tried to look at details on the job step I got the following: Not very helpful. The password had to be saved somewhere, but where?? All of a sudden I remembered that there was a system table I hadn’t queried yet: SELECT sjs.command FROM msdb.dbo.sysjobs sj JOIN msdb.dbo.sysjobsteps sjs ON sj.job_id = sjs.job_id WHERE sj.name = 'Run LePackage' The result: “Well, that’s really secure”, I thought to myself. Cheers, -Argenis

• Error with TextMate 2 --shell-escape and gnuplot 10.8.2

  - by Manuel

  I have had TM 1.X since a long time ago, but a week ago I updated my system to Mountain Lion 10.8.2 and installed TM2. The problem is that I write with LaTeX, and sometimes I use gnuplot for the graphs (I installed gnuplot with macports). But now it doesn't work because the --shell-escape doesn't work, this is the error message I get: Package pgfplots Error: Sorry, the gnuplot-result file '"untitled 2.pgf-plot.table"' could not be found. Maybe you need to enable the shell-escape feature? For pdflatex, this is ' pdflatex -shell-escape'. You can also invoke ' gnuplot .gnuplot' manually on the respective gnuplot file.. And then, looking around I discovered that it's not just gnuplot but everything which needs --shell-escape. Question What happened? How can I get TM have the correct rights so this works? It worked right in Snow Leopard with TM 1.5.

• OBJECT_Name parameters and dbid

  - by steveh99999

  If you've been using SQL Server for a long time, you may have been used to using the OBJECT_NAME system function in the past - especially useful when converting table IDs into table names when querying sysobjects and sysindexes..... However, if you're an old-school DBA  - did you know since SQL 2005 service pack 2 it  accepts a  second parameter ? database_id.. For example, this can be used to summarize some useful information from sys.dm_exec_query_stats. When reviewing SQL Server performance - it can be useful to look at the most heavily used stored procedures rather than inefficient less frequently used procedures.  Here's a query to summarize performance data on the most-heavily used stored procedures across all databases on a server  :-SELECT TOP 20 DENSE_RANK() OVER (ORDER BY SUM(execution_count) DESC) AS rank, OBJECT_NAME(qt.objectid, qt.dbid) AS 'proc name', (CASE WHEN qt.dbid = 32767 THEN 'mssqlresource' ELSE DB_NAME(qt.dbid) END ) AS 'Database', OBJECT_SCHEMA_NAME(qt.objectid,qt.dbid) AS 'schema', SUM(execution_count) AS 'TotalExecutions',SUM(total_worker_time) AS 'TotalCPUTimeMS', SUM(total_elapsed_time) AS 'TotalRunTimeMS', SUM(total_logical_reads) AS 'TotalLogicalReads',SUM(total_logical_writes) AS 'TotalLogicalWrites', MIN(creation_time) AS 'earliestPlan', MAX(last_execution_time) AS 'lastExecutionTime' FROM sys.dm_exec_query_stats qs CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) AS qt WHERE OBJECT_NAME(qt.objectid, qt.dbid) IS NOT NULL GROUP BY OBJECT_NAME(qt.objectid, qt.dbid),qt.dbid,OBJECT_SCHEMA_NAME(qt.objectid,qt.dbid)

• Setting page parent to a private page in Wordpress 2.8

  - by Gareth Simpson

  I have a site developed in Wordpress 2.7 that makes extensive use of private pages as the parents of public pages. The private pages are never meant to be seen, they are just there to act as containers for the other pages. Since upgrading to Wordpress 2.8, it seems this isn't possible any more. Private pages no long show up in the drop box of pages I can use as a parent, and if I edit a page with a private parent, it loses the parenting information. Is there anything I can do about this?

• Diagram that could explain a state machine's code?

  - by Incognito

  We have a lot of concepts in making diagrams like UML and flowcharting or just making up whatever boxes-and-arrows combination works at the time, but I'm looking at doing a visual diagram on something that's actually really complex. State machines like those that parse HTML or regular expressions tend to be very long and complicated bits of code. For example, this is the stateLoop for FireFox 9 beta. It's actually generated by another file, but this is the code that runs. How can I diagram something with the complexity of this in a way that explains flow of the code without taking it to a level where I draw every single line-of-code into it's own box on a flowchart? I don't want to draw "Invoke loop, then return" but I don't want to explain every last detail. What kind of graph is suitable to do this? Is there already something out there similar to this? Just an example of how to do this without going overboard in complexity or too-high-level is really what I want. If you don't feel like looking at the code, basically it's 70 different state flags that could occur, inside an infinite loop that exists to a label based on some conditions, each flag has it's own infinite loop that exists to a label somewhere, and each of those loops has checks for different types of chars, which then runs off into various other methods.

• DopeWarz 2010

  - by Theo Moore

  A few (6?) weeks ago, I started a project that I've always wanted to do. I am doing a re-write of the old VB6 game DopeWars with a partner in crime. I loved that game and spent many, many hours wasting time playing it years ago. I liked it so much, I even registered it (it was $5...even then, that wasn't much to spend). The VB6 version itself was a port of the old DOS game DrugWars (never go to play that). I needed a game project to work on as it's been far too long since I've done any game work. There is surprising amount of logic built into the game (there is the way I'm writing it, anyway) with what is really a minimal interface. My design goal was to have an object model that could be easily adapted to any interface and so far, I've managed to do that. I am even considering a web-based version that could run via Facebook (no clue how to do that...yet). I've enlisted the help of one of my DBA buddies to work on the interface while I am working on the object model. So far, this arrangement has gone well. The logical separation of concerns allows for us to collaborate easily. Once we get to the Facebook step, it will be great to have a DBA "on staff" to help that part off of the ground. The object model is probably about 60% complete with quite a bit of testing to go. More on this as we go....

• When did Red Hat start shipping PHP 5.3 with 5.x?!?

  - by Jason

  Okay this is a PSA more than a question because I know the answer: January 13, 2011. See: https://rhn.redhat.com/errata/RHEA-2011-0069.html Colour me surprised though, didn't hear anything about in the blogosphere until I got a Security Errata notice today. I have been using the REMI repo for this in the past but will switch over to the Red Hat blessed PHP 5.3. Don't down-vote me bro! I'll select as the best answer the source that broke the news first (other than Red Hat of course). People have wanted this for so long I'm just amazed that it's finally happened!

• Mysterious winamp ratings that come from nowhere

  - by Phenom

  Winamp gives the option to rate songs. This is not a new feature. Everytime I would reinstall Windows and reinstall Winamp my ratings would all go away as expected, and I would have to re-rate everything. However, this time when I reinstalled Winamp, after using it for a few days, songs would appear in my top rated list as being rated. Some of these I remember rating a long time ago before I reinstalled Windows, and some of these I don't remember ever rating. Where are these ratings coming from?

• Upgrade Mysql to 5.5 with cPanel

  - by Merrill

  I have a cPanel installed on a CentOS server and it includes an old version of Mysql. Has anyone tried upgrading Mysql to 5.5 on a cPanel managed server? If so, I would really like some guidance. I read, on the cPanel forum, that it's not supported and one user complained, after manually upgrading his version of Mysql, cPanel automatically removed it, but that was a long time ago. Also, I'm a newbie to Linux, so please forgive any dumb questions. Help... Thanks.

• Boot failure after update and system crash 11.10

  - by Alubuntu

  I'm using: Dell XPS M1330 laptop, Ubuntu 11.10 32bits, single boot (only Linux OS), Virtualbox (with Windows XP on virtual machine). System crashed while working with a very heavy image on GIMP (and Virtualbox was on). During the same session, I made an automatic system update, but don't know what was exactly updated. After the crash the system doesn't boot. Always freezes on terminal screen but at different stages, ""Starting CUPS printing spooler/server", "Checking battery state", "mountall: plymouth command failed", etc. Sometimes indicates [failed] in some of the processes and sometimes they're all [ok]. Did a Boot info summary with boot-repair and gave me this report http://paste.ubuntu.com/1050743/ This is not a new install, have been using it for almost 6 months...though since last month it couldn't halt..it started shutting down and stopped at black screen with fan on and on/off light still on (I used to finish the shutdown process by forcing halt with a long-press of the power button). I don't know if these has anything to do with the boot failure. Is there anyway I can solve this issue (the boot failure) or make some sort of system check to find out what is the cause of the problem? I wasn't sure if this was the right place to ask the question, so I also did it at https://answers.launchpad.net/ubuntu/+question/201004

• Advantages of Singleton Class over Static Class?

  Point 1)Singleton We can get the object of singleton and then pass to other methods.Static Class We can not pass static class to other methods as we pass objectsPoint 2) Singleton In future, it is easy to change the logic of of creating objects to some pooling mechanism. Static Class Very difficult to implement some pooling logic in case of static class. We would need to make that class as non-static and then make all the methods non-static methods, So entire your code needs to be changed.Point3:) Singleton Can Singletone class be inherited to subclass? Singleton class does not say any restriction of Inheritence. So we should be able to do this as long as subclass is also inheritence.There's nothing fundamentally wrong with subclassing a class that is intended to be a singleton. There are many reasons you might want to do it. and there are many ways to accomplish it. It depends on language you use.Static Class We can not inherit Static class to another Static class in C#. Think about it this way: you access static members via type name, like this: MyStaticType.MyStaticMember(); Were you to inherit from that class, you would have to access it via the new type name: MyNewType.MyStaticMember(); Thus, the new item bears no relationships to the original when used in code. There would be no way to take advantage of any inheritance relationship for things like polymorphism. span.fullpost {display:none;}
