• Why does subshell not inherit exported variable (PS1)?

  - by amn

  After some debugging I finally narrowed down the problem as to why my X session xterm prompt does not appear according to my PS1 setting. If I run sh -c env, it doesn't even show PS1 in the list. Why? export PS1='test' sh -c env # No PS1 in the list, default prompt appearance (shell name + version) Substituting sh with bash yields same result, alas the behavior appears to be the same for both shells/modes. As far as I understood from man bash, the environment resulting from command run by shell with -c should include the exported variables. And it does - exporting FOOBAR results in FOOBAR listed in env run by subshell. It appears that the story is different if the variable is PS1 however. What is going on? I want my prompt propagated throughout the process tree and system. For matters sake, it is set in /etc/profile.d/user.sh (a file I created myself) with the following: PS1='\u@\H \w \$ ' export PS1 I am running Arch Linux (updated yesterday.)

• Installing the Apple Root Certificate Authority on CentOS CLI

  - by Daniel Hollands

  I could be barking up the wrong tree here, but I'm looking for help on installing Apple's Root certificate (http://www.apple.com/certificateauthority/) on a CentOS server via the command line - which I need to send messages to their APNS system. The code I'm using for this purpose is a variation on this: https://github.com/jPaolantonio/SimplePush/blob/master/simplepush.php - which works perfectly well on a Windows server, but as soon as we try to use it on a CentOS one, it falls over. We're lead to believe this has something to do with not having the CA installed on our CentOS box - but all efforts to do so have failed. As the CentOS server is headless, we need the ability to do this via the commandline. Can someone help?

• Will Hotmail DELIVER to spam-friendly ISP?

  - by Oddthinking

  I have a user who is using Hotmail to communicate with one of our suppliers. Recently, Hotmail started bouncing emails to that address (while other ISPs are working fine.) Hotmail bounce messages contain very little details. Investigating, I found that the supplier's ISP has appeared on a blacklist of ISPs who do not do enough to prevent spamming from their users. (Note: Neither my user nor the supplier are mass-mailing.) In the circumstances, I can understand Hotmail declining to accept emails from the host, or accepting them but being quick to mark them as spam. However, I am surprised that they might refuse delivery. Does this sound plausible to you, or am I barking up the wrong tree?

• Migrating to LDAP

  - by Frank Brenner

  Hi Folks, I've started a new job at a house where they've got an amazingly unruly patchwork of Linux, xBSD, and OpenSolaris boxes. Every box has its own user auth using local /etc/passwd, etc. Users/Groups have differing uids/gids on each machine, and each machine has its own /home/ tree. (no central NAS /homes) My job is get get everything into an LDAP directory and use that for login auth. How do I get LDAP to deal with the differing uids/gids? Thanks.

• What XSS/CSRF attacks (if any) to be aware of when allowing video embeds?

  - by fireeyedboy

  I've been assigned a project for a website where users will be allowed to upload video's (using a YouTube API) but more importantly (for me) they will also be allowed to submit video embed codes (from numerous video sites, YouTube, Vimeo, etc. etc.). Having no experience with allowing users to embed video: How can I best protect against cross site scripting and/or cross site request forgery attacks specifically for video embedding? What are some of the common pitfalls to watch for? At a minumum I would think to strip all tags except <object> and <embed>. But I have a feeling this will not be enough, will it? If it is of importance, the environment will be: PHP/Zend Framework MySQL Bonuspoints: Is there a common minimum golden rule/code template for video embed codes that are valid across all video sites that I could use to filter the input?

• How do I handle a low job offer for an entry level position?

  - by user229269

  Hi guys! I recently graduated with MS in CS and I am excited because I just received a job offer from a company I really like for an entry-level sw engineer position. The thing is that, although the salary is not my priority and I care way more about gaining experience, their offer unfortunately is way below of what I expected. Actually after I did some research I realized that, comparing to the average salary range for the entry-level sw engineering positions in my area (one of the most expensive areas in the US) supposedly [X - Y]$ (where X is the lowest average and Y the highest), their offer is 20% below X! I wouldnt have a problem accepting an offer around X but this one is even lower than the lowest. Can I counter offer the X which is 20% more than what they offered me but at the same time is the minimum average? -- And mind you that I didnt even take under consideration the fact that I hold a MS degree which in many cases yields to a 5-10% more pay.

• purchasing source code from third party vendor

  - by Richard Friend

  Hi Our company uses some third party vendors to write some of our external facing web sites, however with one vendor we keep experiencing over inflated charges for simple changes and it has been decided to bring the product in-house. I have been tasked to provide a list of deliverables/checkpoints that would form a part of the agreement. what is the minimum you would expect if you are purchasing the source code of a product that you have paid for the development of, should we expect code for any custom libraries they may be using that were written not for us etc.. This is all written in .net so i am well aware we could just get the code via reflector, however i dont think my boss would go for this ;-)

• Re-measuring custom item renderer on a List

  - by leolobato

  I'm writing an Adobe Air client to a service similar to Twitter. On the timeline (List component) I have a custom item renderer which is basically a Canvas with a fixed-width Image and a Text control, which is multi-line. If the text is long enough to change the Canvas height, it will only be resized if I manually change the width of the Window, forcing a redraw of all renderers. If I simply scroll through the List, all "new" renderers will have the minimum height possible (which is the Image height). Any ideas on how to force the re-measurement of the renderer when I set it's data? Thanks in advance! :)

• Aes key length significance/implications

  - by cppdev

  Hi, I am using a AES algorithm in my application for encrypting plain text. I am trying to use a key which is a six digit number. But as per the AES spec, the key should be minimum sixteen bytes in length. I am planning to append leading zeros to my six digit number to make it a 16 byte and then use this as a key. Would it have any security implications ? I mean will it make my ciphertext more prone to attacks. Please help.

• Error debugging - Conversion from String to Double

  - by Jamie Taylor

  I'm doing some error debugging trying to get the errors on our website down to a minimum and there seems to be an error that is popping up quite a lot Conversion from string "" to type 'Double' is not valid. I'm unable to replicate this problem but I can see that it is happening. I've been looking through the code in one of the pages and strolled across this Dim varWeek As String If varWeek < 10 Then 'Do something' End If Could this be causing the problem as it is trying to see if a String is less than 10 which is an Integer? As I said before as I am unable to see this error in the first place so changing this to an Integer doesn't change anything on my system. Thanks.

• How do I catalog files on several external hard drives that I want to store off-line? OSX

  - by raudi

  My partner, an artist, has more than 10 external hardisks both USB and firewire and every 2-3 months a new one has to be added (She's working with videos and pictures) currently its 10TB and growing so too much for a affordable NAS. Right now the files are not indexed and I think can not be searched with spotlight because not all drives can be connected at the same time. So if she wants to search for a file, she has to guess which disk/disks (based mostly on the date) and then search several drives. Now I'm looking for a solution to index/catalog the drives, something like GentibusCD Cathy Disclib (all these solutions are unfortunately Windows only) Is there any software for OSX that will catalog all the hard drives, so she can search the catalog, find the files, and get the ID of the disk / disk name that has the content? Preferably something with a GUI so my partner can also use it easily Preferably with Thumbnails for pictures/videos (But even an equivalent to "tree /F /A" would be better than nothing)

• Tracking the linux config with git: how?

  - by Pierre

  I'd like to track my linux configurations with git. My idea is to have a branch for each server. /etc is not the only one directory to be tracked (I won't git init in '/etc' ) As far as I could see, it is possible to init a git for a distant directory. I tried this: # mkdir -p /git/.git # cd /git # git --work-tree=/ --git-dir=/git/.git init Initialized empty Git repository in /git/.git/ 1) Creating a new branch before everything is not possible # git branch server1 fatal: Not a valid object name: 'HEAD'. 2) adding a file in master/HEAD is not possible # touch README.md # git add README.md fatal: Unable to create '//.git/index.lock': No such file or directory how should I properly setup git to track my system-config ? Thanks. P.

• c program for this quesion

  - by sashi

  suppose that a disk drive has 5000 cylinders, numbered 0 to 4999. the drive is currently serving a request at cylinder 143 and the previous request was at cylinder 125. the ueue of pending requests in the given order is 86,1470,913,17774,948,1509,1022,1750,130. write a 'c' program for finding the total distance in cylinders that the disk arm moves to satisfy all the pending reuests from the current heads position, using SSTF scheduling algorith. seek time is the time for the disk arm to move the head to the cylider containing the desired sector. sstf algorithm selects the minimum seek time from the current head position.

• Why my browsers display XML files as blank pages?

  - by n1313

  Every time I open an XML file, all I get is blank page instead of tag tree. The file itself is correct and loads okay, I can see it via View Source or in the Firebug. I've tried turning off all my addons and tried running Firefox in safe mode, but the problem was not solved. I'm guessing that I've messed up my configuration somehow and Firefox now tries to render XML files as HTML ones. I've tried googling, but with no success. Help, please? UPD: example file: http://lj.lain.ru/3/1273657698603.sample.xml Also I've noticed that somehow all of the browsers on the machine are now acting the same, so I'm changing the question accordingly

• Why do we still have to use drive letters to identify file systems?

  - by Charles E. Grant

  A friend has run into a problem where they installed Windows 7 from an external drive, and the internal boot drive is now assigned to H:. Theoretically this shouldn't cause problems because there are programming interfaces for getting the drive letter for the system drive. In practice though, there are quite a few programs that assume that C: is the only possible location for the system directories, and they refuse to run with the system directories on H:. That's not Microsoft's fault, but it's a pain none-the-less. The general consensus seems to be that a re-install, setting the internal boot drive to C:, is the only way to avoid fix these problems. UNIX-like systems display all file systems in a single unified directory tree and mostly seem to avoid problems like this. Is it possible to configure a Windows system without reference to drive letters, or does the importance of backwards compatibility mean that Windows will be working with drive letters from now until doomsday?

• Php efficiency question --> Database call vs. File Write vs. Calling C++ executable

  - by JP19

  Hi, What I wish to achieve is - log all information about each and every visit to every page ofmy website (like ip address, browser, referring page, etc). Now this is easy to do. What I am interested is doing this in a way so as to cause minimum overhead (runtime) in the php scripts. What is the best approach for this efficiency-wise: 1) Log all information to a database table 2) Write to a file (from php directly) 3) Call a C++ executable, that will write this info to a file in parallel [so the script can continue execution without waiting for the file write to occur ...... is this even possible] I may be trying to optimize unnecessarily/prematurely, but still - any thoughts / ideas on this would be appreciated. (I think efficiency of file write/logging can really be a concern if I have say 100 visits per minute...) Thanks & Regards, JP

• Connecting Ingres from C

  - by avesus

  I need to connect to an Ingres supplied demodb through OpenAPI, both Ingres and C application running on windows. What i have done: Created a "node" in the Ingres Network Utility named "usernode". created user accounts in the Ingres installation (named "user" password "user") and in the Windows user management (the same creds.) Granted necessary privileges to the user in the database. In C code i have called IIapi_connect() function with an IIAPI_CONNPARM structure. Used members: co_target = "usernode::demodb", co_username = "user", co_password = "user" But IIapi_connect() call returns an error: "User provided a vnode as part of the database name (vnode::dbname), but connection information for that vnode is missing. Enter connection information for the vnode using NETUTIL." Anybody knows something that is a weird concept "node"? What are the minimum steps (in the database administration and the function parameters passing) necessary for the successful connect?

• How necessary is using PHP filters?

  - by Jamie

  I'm a relatively newbie to PHP and just making my way through the W3Schools tut. The tut makes a big point of saying you must always filter external data (i.e. cookies, form data etc). I'm writing a fairly simple system that talks with a third party Joomla extension. It's at a prototype stage where I'm just wanting to demonstrate the functionality in a minimum viable product. Basically, I'd like to know... what's the worst that could happen in I don't filter content. Are we talking 'I might get a bunch of spam', or 'a good hacker could get root server access'? Have hunted around online, but would love any of your experience / insight on the matter!

• How to integrate an open source C program instead of calling its executable through a system call?

  - by ihamer

  I have an executable (fossil scm) that is being invoked by my program externally through ::CreateProcess windows call. The stdout and stderr are then captured. Since the source code for fossil is available, I would prefer to create a static library out of it and issue calls directly. Currently, communication to fossil is done through the command line parameters, and the communication back is through the process return code, stdout and stderr. Fossil writes to stdout/err through printf and fprintf calls. What is the best way to solve this with minimum alteration of fossil source? Is there a reliable and cross-platform way to intercept stdout/err and send it into a memory buffer?

• Determine display or VNC session based on PID

  - by Daniel Kessler

  I frequently VNC into a server where we run many concurrent computationally intensive matlab processes. Sometimes, one of my processes misbehave, which I can see from top, but I have a hard time figuring out which VNC session it's running on, or more specifically, which display it's running on. Suppose I see that PID 8536 looks like a resource hog, and I want to investigate. Because it's a matlab session, I know there is likely an IDE open somewhere, and I want to check to see if anything important is happening before I kill it. We've solved this somewhat awkwardly in the past by identifying which PTY 8536 was launched from, then looking at a process tree to figure out things launched in that context, scrolling up, and seeing the VNC initialization. Seems like there must be a better way to go PID - X Display (or VNC Session).

• Geocoding service for a startup?

  - by Sologoub

  I'm working on an idea for a service that uses geocoded data (lat/lng) form a US address. Google maps API v3 has been awesome, until I read the terms of service and acceptable uses a little closer. The problem is that the terms seem to prohibit use of the maps API for any commercial use where the site is not freely accessibly to the public, such as a subscription based service. The alternative offered is Google Maps API Premier, but at $10,000 per year minimum, it's just not possible at this time. Same goes for services offered by Yahoo! and MS - initial fees are small for enterprises, but for a very early stage startup (not even a finished prototype yet!) it's just not doable. Geocoding process needs to be real-time and volume would be very small - user would enter address at setup time and only update it if needed. Any help is greatly appreciated!

• Mysql query taking too much time

  - by aditya

  I have problem related to mysql database. i am linux webserver admin and i am facing a problem with a mysql query. The database is very small. I tried to track in logs and found that a query is taking minimum 5 sec to respond . The first page of site is coming from the database. Client are using cms. when the server gets some number of hits database server starts to give response very slowly and wait time increases from 5 sec to several seconds. I checked slow query logs { Query_time: 11.480138 Lock_time: 0.003837 Rows_sent: 921 Rows_examined: 3333 SET timestamp=1346656767; SELECT `Tender`.`id`, `Tender`.`department_id`, `Tender`.`title_english`, `Tender`.`content_english`, `Tender`.`title_hindi`, `Tender`.`content_hindi`, `Tender`.`file_name`, `Tender`.`start_publish`, `Tender`.`end_publish`, `Tender`.`publish`, `Tender`.`status`, `Tender`.`createdBy`, `Tender`.`created`, `Tender`.`modifyBy`, `Tender`.`modified` FROM `mcms_tenders` AS `Tender` WHERE `Tender`.`department_id` IN ( 31, 33, 32, 30 ); } Every line in the log is same only there is diff in Query time. Is there any way tweak the performance?
