  • Why does an EXE file that does *nothing* contain so many dummy zero bytes?

    - by Lambert
    Hi, I've compiled a C file that does absolutely nothing (just a main that returns... not even a "Hello, world" gets printed), and I've compiled it with various compilers (MinGW GCC, Visual C++, Windows DDK, etc.). All of them link with the C runtime, which is standard. But what I don't get is: When I open up the file in a hex editor (or a disassembler), why do I see that almost half of the 16 KB is just huge sections of either 0x00 bytes or 0xCC bytes? It seems rather ridiculous to me... is there any way to prevent these from occurring? And why are they there in the first place? Thank you!

  • Pressing zero key brings up lock/switch user screen in W7

    - by qinghua
    This issue started after my cat walked all over the keyboard... Whenever I press the "zero" key, the screen goes black and I'm taken to the lock/switch user screen. The other functions of the key work fine - it can produce ) and / like usual. Numlock is off, and as far as I know, my computer doesn't have Function Lock. If I log out of my user account and sign in as a guest, the "zero" works again, but if I create a new user profile, it doesn't work. I get the same issue when I hit "zero" using the on-screen keyboard. My keyboard layout is set to US English. I've uninstalled and reinstalled the ATK package, and updated my keyboard drivers. I have an ASUS U43JC-X1 laptop running Windows 7, and I haven't installed any new programs lately.

  • SharpDX and game engines, back to zero?

    - by Baboon
    I'm a desktop developer (I mainly do WPF for a living) but I want to make games as a hobby. So a few months ago, I started reading blogs, gamedevSE, you name it. I understand in the C++ DirectX world, you have engines such as Unity3D with designers and whatnot, but as much as I'm ok to spend months understanding game development, I'd prefer to stay with my comfy C#. So I thought I'd develop my first games in /C#/DirectX through SharpDX But then, I can't use game engines anymore, since they're made for C++DirectX and not SharpDX. (ok, I could do P/Invokes but that defeats the purpose of SharpDX). I do know about XNA, and I also do know I can't publish to the marketplace with it (and quite frankly, I don't really want to learn an API that is in jeopardy). So how do you conceal writing games in C# and using existing game engines instead of reinventing the wheel? wait for ports? So I've found out the following: After doing the first tutorials of MOgre and digging around, it seems MOgre gives you the worse of both worlds: . You can't port it with Mono because it directly references a C++/CLI dll (Ogre) and C++/CLI isn't supported by Mono. And since it's not C++ itself, you can't make a pure build. Which, as far as I understand, means I'd be stuck on windows (and not even WinRT/Metro compatible), without capability of porting anything to mobiles or other OS (Mac/Linux). Even though it looks really nice to develop with MOgre, I'd like to learn something a little more open to future broadening. On the other hand, MonoGame seems to be a rewrite of XNA with SharpDX which sounds very promising: Mono allows me to easily port my games to other platforms, mobiles included. SharpDX allows me to access the latest DirectX versions XNA would be my first choice if only MS showed some hope for the future It really looks like MonoGame is nothing else than XNA on SharpDX. Axiom looks good too but I lack info on the subject (and pages with poor design don't give me a good feeling about an API...) XNA with SunBurn looks good: It should be portable to Mono (can anyone with experience give us feedback on that?), thus multi-platform. It's then marketplace-able since Mono itself is. Did I miss something or are 2) and 4) my best options (aside from the fact Mono doesn't support any XAML)?

  • Keep website and webservices warm with zero coding

    - by oazabir
    If you want to keep your websites or webservices warm and save user from seeing the long warm up time after an application pool recycle, or IIS restart or new code deployment or even windows restart, you can use the tinyget command line tool, that comes with IIS Resource Kit, to hit the site and services and keep them warm. Here’s how: First get tinyget from here. Download and install the IIS 6.0 Resource Kit on some PC. Then copy the tinyget.exe from “c:\program files…\IIS 6.0 ResourceKit\Tools'\tinyget” to the server where your IIS 6.0 or IIS 7 is running. Then create a batch file that will hit the pages and webservices. Something like this: SET TINYGET=C:\Program Files (x86)\IIS Resources\TinyGet\tinyget.exe"%TINYGET%" -srv:dropthings.omaralzabir.com -uri:http://dropthings.omaralzabir.com/ -status:200"%TINYGET%" -srv:dropthings.omaralzabir.com -uri:http://dropthings.omaralzabir.com/WidgetService.asmx?WSDL - status:200 First I am hitting the homepage to keep the webpage warm. Then I am hitting the webservice URL with ?WSDL parameter, which allows ASP.NET to compile the service if not already compiled and walk through all the operations and reflect on them and thus loading all related DLLs into memory and reducing the warmup time when hit. Tinyget gets the servers name or IP in the –srv parameter and then the actual URI in the –uri. I have specified what’s the HTTP response code to expect in –status parameter. It ensures the site is alive and is returning http 200 code. Besides just warming up a site, you can do some load test on the site. Tinyget can run in multiple threads and run loops to hit some URL. You can literally blow up a site with commands like this: "%TINYGET%" -threads:30 -loop:100 -srv:google.com -uri:http://www.google.com/ -status:200 Tinyget is also pretty useful to run automated tests. You can record http posts in a text file and then use it to make http posts to some page. Then you can put matching clause to check for certain string in the output to ensure the correct response is given. Thus with some simple command line commands, you can warm up, do some transactions, validate the site is giving off correct response as well as run a load test to ensure the server performing well. Very cheap way to get a lot done.

  • Zero bytes on home partition

    - by Michael Z
    I decided to replace the hard drive on my machine running Ubuntu 12.04 LTS . After using the new hard drive for a few days, I noticed that the new hard drive has bad sectors. So I decided to plug my old hard drive back in. First, I plugged both hard drives in and copied some data files from the new hard drive to the old one. After unplugging the new hard drive, I booted the computer with the old hard drive, and here I got a surprise: I can see 0 bytes available on my /home partition! The df utility shows that the /home partition has 0 available bytes. I have tried to move some files. But I still has 0 bytes on /home! However, GParted correctly shows that the available size is near 2Gb. UPDATE 1: To my surprise, System Monitor shows me that approximately 2 Gb are free and 0 bytes are available on the /home partition. It's slightly shocked me! Are "free" and "available" not the same? Any help is really appreciated!

  • Google Webmaster Tools Index dropped to Zero [closed]

    - by Brian Anderson
    Earlier this year I rebuilt my website using ZenCart. Immediately I saw a drop in index status from 59 to 0. I then signed up for Google Webmaster Tools and noticed the Index status took a dramatic drop and has never recovered. I have worked to add content and I know I am not done, but have not seen any recovery of this index since. What confuses me is when I look at the sitemap status under Optimization it shows me there are 1239 submitted and 1127 pages indexed. Most of my pages have fallen off page one for relevant search terms and some are as far back as page 7 or 8 where they used to be on the first page. I have made some changes in the past week to robots.txt and sitemap.xml, but have not seen any improvements. Can anyone tell me what might be going on here? My website is andersonpens.net. Thanks! Brian

  • How to achieve zero down time

    - by Hiral Lakdavala
    For an application we want to achieve zero database and application down time using Active Active configuration. Our dB is Oracle Following are my questions: How can we achieve active active configuration in Oracle? Will introducing Cassandra/HBase(or any other No SQL dbs) cloud help in zero downtime or it is only for fast retrieval of data in a large db? Any other options? Thanks and Regards, Hiral

  • Defend zero-based arrays

    - by DrJokepu
    A question asked here recently reminded me of a debate I had not long ago with a fellow programmer. Basically he argued that zero-based arrays should be replaced by one-based arrays since arrays being zero based is an implementation detail that originates from the way arrays and pointers and computer hardware work, but these sort of stuff should not be reflected in higher level languages. Now I am not really good at debating so I couldn't really offer any good reasons to stick with zero-based arrays other than they sort of feel like more appropriate. I am really interested in the opinions of other developers, so I sort of challenge you to come up with reasons to stick with zero-based arrays!

  • Perl pattern matching with zero width assertion

    - by Simone
    Hi everyone, I can't get why this code work: $seq = 'GAGAGAGA'; my $regexp = '(?=((G[UCGA][GA]A)|(U[GA]CG)|(CUUG)))'; # zero width match while ($seq =~ /$regexp/g){ # globally my $pos = pos($seq) + 1; # position of a zero width matching print "$1 position $pos\n"; } I know this is a zero width match and it dosn't put the matched string in $&, but why does it put it in $1? thank you!

  • ActionScript display zero value

    - by bwong
    It seems the number Datatype handles zeros and nulls the same. I need to display a zero value on the screen, but AS displays nothing. When it's saved, the value is saved as a zero, and therefore shows up zero on the screen. Is there a way to display the zero value using a new object? public class myObject{ private var numVar:Number } My AS file: var temp:MyObject temp.numVar = 0; When I debug, temp.numVar contains a value of 0, but does not show anything on the UI. If this object is then saved to the DB, and then displayed to the UI, it shows a 0. My question is - how do I get temp.numVar to display 0 before persistenting it to the DB?

  • Windows 7 won't load unless other harddrives "disconnect"ed in UEFI shell

    - by lmz
    I have three disks, one GPT partitioned containing Windows 7 and Debian, the other MBR partitioned containing CentOS, and the other one MBR partitioned, empty. It used to work (loading Windows boot manager using rEFIt) but now after installing CentOS and OpenIndiana on the second drive, Windows won't boot. The logo is displayed briefly and then a text mode scrollbar "Loading files", then back to the rEFIt menu. The only thing that makes it work is if I drop into the UEFI shell and run disconnect XX where XX is the device handle of the other hard drives (obtained from running devices). This makes me think that the bootloader is getting confused about where the Windows partition is. Is there any information on how the Windows UEFI boot loader finds the Windows partition, or is there any logging I can turn on to help troubleshoot this issue?

  • Files on ext4 on Drobo with corrupt, zero-ed out blocks

    - by Patrick
    I have a 2TB ext4 file system (Ubuntu running Linux kernel 2.6.31-22-server x86_64). This file system is the second drive on a Drobo box plugged in via USB. We've not had problems on the first drive (Drobo limits drive size to 2TB due to some OS limitations, so if you have more space than that it appears as two separate drives). I am sharing this files with Samba (smbd 3.4.0) with a mix of Windows and Linux workstations. Recently we've been experiencing some data corruption in multiple files. In many cases I have an un-corrupt original file stored on one of the workstations. These are binary files of various formats, (e.g. SQLite, but others as well). I used "split" to split a corrupt and uncorrupt file into 4096 byte chunks (this is the block size of the ext4 file system). I then ran md5sum on pairs of chunks and discovered that the chunks matched in many cases and in every case where they did not match, the corrupt chunk was a solid chunk of zeroes (620f0b67a91f7f74151bc5be745b7110 for what it's worth). I'm trying to track down a culprit but am a bit at a loss. I don't believe Samba is at fault since I'm using it without issue on the first drive exported by the Drobo. What can I do to narrow this down and find out what's going on?

  • TrueCrypt-ed Windows XP reseting administrative password

    - by Predrag Punosevac
    I have inherited a laptop running Windows XP 64bit professional from a former system admin of my Lab. The laptop is encrypted with TrueCrypt and luckily I have a password for TrueCrypt and can boot and login into the guest account. However this is where my problems starts. There are four account on the laptop three of which do have administrative privileges. However nobody of two formers members of the lab and one current member remember their passwords. I was given the assignment of recovering 2TB of data from that laptop. How does one go about reseting administrative password in Windows in particularly in the presence of TrueCrypt? If you are wondering I have never used Windows in my life so the only thing I usually with any Windows machine is just wipe out entire HDD and install OpenBSD.

  • Problems when loop over a series of ssh-ed commands

    - by Jack Medley
    I have a series of server machines which I want to run the same command on. Each command takes hours and (even though I am running the commands using nohup and setting them to run in the background) I have to wait for each to finish before the next starts. Here is roughly how I have set it up: On the host machines: for i in {1..9}; do ssh RemoteMachine${i} ./RunJobs.sh; done Where RunJobs.sh on each remote machine is: source ~/.bash_profile cd AriadneMatching for file in FileDirectory/Input_*; do nohup ./Executable ${file} & done exit Does anyone know of a way such that I dont have to wait for each job to finish before the next starts? Or alternatively a better way of doing this, I have a feeling what I am do is fairly sub-optimal. Cheers, Jack

  • MySQL based authentication with crypt()ed password fails in Apache 2.2

    - by Fester Bestertester
    I'm trying to set up a simple CalDAV/CardDAV server with a Radicale backend and an Apache 2.2 frontend. So far, it's all nice and simple, but I can't get the MySQL based authentication to work. I'd like to authenticate users against an existing MySQL database, and I need the REMOTE_USER variable to be set (pretty much like in the configuration examples for Radicale). I've tried mod_auth_mysql, which authenticated the users nicely, but failed to set the REMOTE_USER variable. The newer alternative seems to be mod_authn_dbd, which doesn't seem to like the crypted passwords in the MySQL database. According to the documentation, crypted passwords should work, so maybe I'm just missing a simple parameter. The configuration looks like this: DBDriver mysql DBDParams "sock=/var/run/mysqld/mysqld.sock dbname=myAuthDB user=myAuthUser pass=myAuthPW <Directory /> AllowOverride None Order allow,deny allow from all AuthName 'CalDav' AuthType Basic AuthBasicProvider dbd require valid-user AuthDBDUserPWQuery "SELECT crypt FROM myAuthTable WHERE id=%s" </Directory> I've tested the query, it works fine. And as mentioned before, mod_auth_mysql worked nicely against the same database, but didn't set the required variables. Am I just missing some configuration parameter? Or is mod_authn_dbd just not the right tool to achieve what I want?

  • Zero sized tar.gz file found inside a tar.gz file

    - by PavanM
    My current directory contains a single file like this- $ls -l -rw-r--r-- 1 root staff 8 May 28 09:10 pavan Now, I want to tar and gzip this file like $tar -cvf - * 2>/dev/null |gzip -vf9 > pavan.tar.gz 2>/dev/null (I am aware I am creating the zipped file in the same directory as the original file) When I run the above tar/gzip commands around 20 times, a few times I observe that the final tarred and zipped file pavan.tar.gz file has a ZERO sized pavan.tar.gz file. I am not sure from where is this zero sized file coming into the archive from. Note: I am NOT running tar/gzip commands on an already existing tar.gz file. I always make sure that the directory has only one file before running the commands On googling, as described here, I suspected that the tar.gz being created was also part of the file being archived. But in my case, gzip is the one who's creating the final file and by the time gzip runs, tar should be done tarring. This is happening on AIX but I've used Linux tag too, to draw more attention, as I guess the problem is platform independent.
