• How (and if) to write a single-consumer queue using the task parallel library?

  - by Eric

  I've heard a bunch of podcasts recently about the TPL in .NET 4.0. Most of them describe background activities like downloading images or doing a computation, using tasks so that the work doesn't interfere with a GUI thread. Most of the code I work on has more of a multiple-producer / single-consumer flavor, where work items from multiple sources must be queued and then processed in order. One example would be logging, where log lines from multiple threads are sequentialized into a single queue for eventual writing to a file or database. All the records from any single source must remain in order, and records from the same moment in time should be "close" to each other in the eventual output. So multiple threads or tasks or whatever are all invoking a queuer: lock( _queue ) // or use a lock-free queue! { _queue.enqueue( some_work ); _queueSemaphore.Release(); } And a dedicated worker thread processes the queue: while( _queueSemaphore.WaitOne() ) { lock( _queue ) { some_work = _queue.dequeue(); } deal_with( some_work ); } It's always seemed reasonable to dedicate a worker thread for the consumer side of these tasks. Should I write future programs using some construct from the TPL instead? Which one? Why?

• Battery life if using GPS and background program

  - by StealthRT

  I was wondering if anyone has created an app that starts in the background and utilizes the GPS to gather the current Lat and Long every minute or so? If you have, would you please provide your battery times? As in, how long does your phone last until its all out of juice from just running that background app with standard cell phone programs. I'm trying to see if it would be worth the time to create an app for myself but if i work for 8 hours and dont have a way of charging my phone during that time then i dont want to be going home and it shut down on me since my app i would create works at my house. I need the app to work since it will see when i am in range of my home (from the GPS) and then send commands to my server at the house from my phone. So thats why it would need to be able to stay in the background doing a check every 1 minute or so. Or only turn on the GPS (Is is doable with iOS? & Android?) whenever its after 5pm each day so that it will minimize the load on the battery?!? Any help or suggestions would be great! Thanks!

• Why does the order of the loops affect performance when iterating over a 2D array? [closed]

  - by Mark

  Possible Duplicate: Which of these two for loops is more efficient in terms of time and cache performance Below are two programs that are almost identical except that I switched the i and j variables around. They both run in different amounts of time. Could someone explain why this happens? Version 1 #include <stdio.h> #include <stdlib.h> main () { int i,j; static int x[4000][4000]; for (i = 0; i < 4000; i++) { for (j = 0; j < 4000; j++) { x[j][i] = i + j; } } } Version 2 #include <stdio.h> #include <stdlib.h> main () { int i,j; static int x[4000][4000]; for (j = 0; j < 4000; j++) { for (i = 0; i < 4000; i++) { x[j][i] = i + j; } } }

• PHP site scheduling Java execution?

  - by obfuscation

  I'm trying to get started on combining my (slightly limited) PHP experience with my (better) Java experience, in a project where I need to allow uploads of Java source files to the server, which the server then executes Javac on to compile it. Then, at a set time (e.g. specified on upload) I need to run that once on the server, which will generate some database info for the PHP site to display. To describe my current programming abilities- I have made many desktop Java programs, and am confident in 'pure' Java, but so far have only undertaken a couple of PHP projects (including using the CodeIgniter framework). My motivation for using PHP as the frontend is because I know it is very fast, lightweight and I will be able to display the results I need very easily with it (simple DB readout). Ideally, the technology used should be able to be developed on a localhost (e.g. WAMP, Tomcat etc..) Is there any advice which you could give on what technology I should consider to use to bridge this gap, and what resources could help in using that technology? I have looked at a few, but have struggled to find documentation helping in achieving what I need.

• Python OOP - object has no attribute

  - by user1744269

  I am attempting to learn how to program. I really do want to learn how to program; I love the building and design aspect of it. However, in Java and Python, I have tried and failed with programs as they pertain to objects, classes, methods.. I am trying to develop some code for a program, but im stumped. I know this is a simple error. However I am lost! I am hoping someone can guide me to a working program, but also help me learn (criticism is not only expected, but APPRECIATED). class Converter: def cTOf(self, numFrom): numFrom = self.numFrom numTo = (self.numFrom * (9/5)) + 32 print (str(numTo) + ' degrees Farenheit') return numTo def fTOc(self, numFrom): numFrom = self.numFrom numTo = ((numFrom - 32) * (5/9)) return numTo convert = Converter() numFrom = (float(input('Enter a number to convert.. '))) unitFrom = input('What unit would you like to convert from.. ') unitTo = input('What unit would you like to convert to.. ') if unitFrom == ('celcius'): convert.cTOf(numFrom) print(numTo) input('Please hit enter..') if unitFrom == ('farenheit'): convert.fTOc(numFrom) print(numTo) input('Please hit enter..')

• No result when Rally.data.WsapiDataStore lacks permissions

  - by user1195996

  I'm calling Ext.create('Rally.data.WsapiDataStore', params), and looking for results with the load event. I'm requesting a number of objects across programs that the user may or may not have read permission for. This works fine for queries where the user has permissions. But in the case where the user does not have permission and presumably gets zero results back, the load event does not seem to fire at all. I would expect it to fire with the unsuccessful flag or else to return with empty results. Since I don't know that the request has failed, my program waits and waits. How can I tell if a this request fails to return because of security? BTW, looking at the network stats, I believe all my requests get a "200 OK" status back. Here is the method I use to create the various data stores: _createDataStore: function(params) { this.openRequests++; var createParams = { model: params.type, autoLoad: true, // So I can later determine which query type it is, and which program requestType: params.requestType == undefined ? params.type : params.requestType, program: this.program, listeners: { load: this._onDataLoaded, scope: this }, filters: params.filters, pageSize: params.pageSize, fetch: params.fetch, context: { project: this.project, projectScopeUp: false, projectScopeDown: true }, pageSize: 1 // We only need the count }; console.log('_createDataStore', this.program, createParams.requestType); Ext.create('Rally.data.WsapiDataStore', createParams); }, And here is the _onDataLoaded method: _onDataLoaded: function(store, data, successB) { console.log('_onDataLoaded', this.program, successB); ... I only see this function called for those queries for which the account has permissions.

• Multiple/Sub quries with codeigniter

  - by user1011713

  I just started with Codeigniter and this is driving me nuts. I have a query that determines whether a user has bought any programs. I then have to use that program's type category to run and determine how many times he or she has recorded a query in another table. Sorry for the confusion but the code hopefully makes sense. I'm having problem returning the two arrays from my Model to my Controller to onto the view obviously. function specificPrograms() { $specific_sql = $this->db->query("SELECT program,created FROM `assessment` WHERE uid = $this->uid"); if($specific_sql->num_rows() > 0) { foreach ($specific_sql->result() as $specific) { $data[] = $specific; $this->type = $specific->program; } return $data; } $sub_sql = $this->db->query("SELECT id FROM othertable WHERE user_id_fk = $this->uid and type = '$this->type'"); if($sub_sql->num_rows() > 0) { foreach ($sub_sql->result() as $otherp) { $data[] = $otherp; } return $data; } } Then in my Controller I have, $data['specific'] = $this->user_model->specificPrograms(); $data['otherp'] = $this->user_model->specificPrograms(); Thanks for any help.

• Can't push to git hub

  - by John

  I just completed chapter one of the Ruby on Rails Tutorial by Hartl. Posted about one minor hitch previously. Now I started chapter two. I swear I did everything by the book, but now when I try: git push -u origin master I get the following messages after entering my passphrase: ERROR: repository not found fatal: could not read from remote repository Please make sure you have the correct access rights and that the repository exists. When I down loaded heroku tools I think it installed a second version of ruby on my machine. In any case I now have two version listed under All Programs. Could this have screwed thing up? The two versions are Ruby 1.9.2-p290 and 1.9.3-p327. Also when I open the command prompt using 1.9.2 there is a wierd thing at the top before I do anything: 'C:\Program' is not recognized as an internal or external command, operable program or batch file. This is then followed by the normal prompt on the next line. I'm wondering if the use of my public keys have some how gotten screwed up. Any help would be appreciated.

• Detecting modifier keys held down during startup in OS/X (or Windows)?

  - by Tom Swirly

  I've searched here and not found any question that really covers this. I have a cross-platform Windows-OS/X application in which I'd like to be able to detect whether modifier keys like shift or control are being held down while the application starts up. We'd like to do this to allow the application to start up without reading its preferences file, in case that somehow gets corrupted (we saw in testing a prefs bug, now fixed, that made the window size 0 by 0, for example). We're using the excellent and comprehensive cross-platform C++ library named Juce. Unfortunately, Juce's master tells me that he believes this is impossible on OS/X at least since you only get keyboard events and there is no way to read the state of the keys unless something changes. Is this true? Or is there some way around this? I'm almost sure I've used Mac programs that used this mechanism to bypass their preferences. Or... stepping up one level... is there another solution to providing the functionality of "run the program but don't read the prefs file" other than "holding a key down while launching the program"? This is consumer software so we can't expect too much from the user. The final solution will end up being a cross-platform one so hints on the Windows side will also be appreciated. Thanks, and be well! I'll report in with progress on my end.

• SMB2 traffic crashes network?

  - by Phil Cross

  We've been having significant network slowdown issues over the past few weeks, primarily on a Friday morning. We run Windows 7 client machines, with Windows Server 2008 R2 servers. What generally happens is the network starts to slow down massively at 08:55 and resumes normal speeds at around 09:20 This affects everything on the network from logging on, resetting passwords, opening programs and files etc. On my client machine, Physical Memory usage remains at around 40% (normal) and CPU usage hovers around 0-10% idle. The servers show memory usage spikes massively and remains quite intense during the times mentioned above. I have taken several wireshark captures, both during the slowdown and when the network operates fine. One of the main things I noticed is the increase in SMB2 entries in the wireshark log during the slowdown. Record Time Source Destination Protocol Length Info 382 3.976460000 10.47.35.11 10.47.32.3 SMB2 362 Create Request File: pcross\My Documents 413 4.525047000 10.47.35.11 10.47.32.3 SMB2 146 Close Request File: pcross\My Documents 441 5.235927000 10.47.32.3 10.47.35.11 SMB2 298 Create Response File: pcross\My Documents\Downloads 442 5.236199000 10.47.35.11 10.47.32.3 SMB2 260 Find Request File: pcross\My Documents\Downloads SMB2_FIND_ID_BOTH_DIRECTORY_INFO Pattern: *;Find Request File: pcross\My Documents\Downloads SMB2_FIND_ID_BOTH_DIRECTORY_INFO Pattern: * 573 6.327634000 10.47.35.11 10.47.32.3 SMB2 146 Close Request File: pcross\My Documents\Downloads 703 7.664186000 10.47.35.11 10.47.32.3 SMB2 394 Create Request File: pcross\My Documents\Downloads\WestlandsProspectus\P24 __ P21.pdf These are some of the SMB2 records from a list of a couple of hundred which original from my computer with a destination of the fileserver. One of the interesting things to note is the last entry in the examples above is for a PDF file. That file was not open anywhere on my computer, or on anyone elses. No folders with the files in were open either. When I took another capture when the network was running fine, there were hardly any SMB2 entries, and the ones that were displayed were mainly from Wireshark. We currently have around 800 computers, 90 Macs and 200 Laptops and Netbooks. Our concern is if this traffic is happening on my computer, is it happening on other computers, and if so, would those computers be adding to the slow network issues? Again, this only happens during certain times. We're pretty sure its not the our antivirus. Is there anything to narrow down whats initializing this SMB traffic during the particular times? Or if anyone has any extra advice, or links to resources it would be appreciate.

• VMware Player loses internet connectivity

  - by Martha

  Periodically, the internet simply stops working in my virtual machine, and the only way I can get it working again is to restart the host computer. Since I use the virtual machine specifically for testing web pages, this is, shall we say, a bother. Details: I have Windows XP Pro running in VMware Player (v. 3.0.0 build-203739) on a Windows 7 host. It's set to NAT (shared IP address) because the firewall won't allow a bridged connection. Every couple of days or so, first the internet slows down to a crawl, then eventually it stops working altogether. Both VMWare and the virtual OS report that they are connected, everything looks just peachy, I can reach the internet from the host, but on the VM, all web pages time out and/or report that the server could not be found. (Browser-independent; tried with IE, FF, Chrome, Safari, and Opera.) When this happens, the only way I've found to restore the internet connectivity is to restart the host machine. Restarting the VM doesn't help, nor does refreshing network connections on either the host or the guest. (Although I'm not entirely sure I've found the proper way to refresh a network connection in Windows 7...) I have not noticed any predictability about when the problem occurs, i.e. it's not immediately after I do anything special. It seems to occur mostly after putting the host to sleep once or twice, but it has happened even if the host has been in continuous use. It also seems independent of when I start using the VM - sometimes, I wake up the VM and the internet is really slow in it, then eventually stops working altogether; other times, I wake up the VM, use it perfectly happily for a while, then suddenly the internet is gone. Does anyone know why this is occurring? Failing that, is there a workaround that's less drastic than restarting the host? (Windows 7 startup times are blazingly fast compared to previous versions of Windows, but it's still a hassle to close all my programs and reopen them again.) Edit: while badges overall are nice, the Tumbleweed badge isn't helping me to solve my problem. Hasn't anyone encountered anything even remotely similar?

• Windows XP SP3 - Library not registered error... IE8 not installing.

  - by Wesley

  Specs to put things in context: AMD Athlon XP 2400+ @ 1987 MHz / 2 x 512MB PC3200 DDR RAM / WD 160GB IDE HDD / 3DFuzion 128MB GeForce 6200 AGP 4x / FIC AM37 / Windows XP SP3 Just recently, I was unable to start Windows Media Player. I clicked it and the busy cursor came up, but then nothing happened. Also, I tried doing a search for a file, and same thing. It would show busy cursor then suddenly stop doing anything. I couldn't find it in the Processes of the Task Manager. (Perhaps I don't know what I'm looking for?) Also, I was trying to update my DirectX, which has been running something older than DX9 9.0c for a while now, except the installation fails due to "internal error". I think the failed DirectX installation has been like that for a while... (I remember trying to install DX9 9.0c a while back, but still failed.) The Windows programs not starting, I don't think I've ever had before... what could be the cause of these problems?! Thanks in advance. =) EDIT1: Weird thing now is that when I try to open User Accounts, I get a message saying "Wrong number of arguments or invalid property assignment." Also, when I'm trying to open services.msc, I'm getting a script error that says that "Library not registered." (Code: 0, URL: res://C:\WINDOWS\System32\mmcndmgr.dll/views.htm) Perhaps this is related to my other question, where I seemed to have an unregistered library of some sort. EDIT2: The DirectX End-User Runtime Web Installer freakishly worked and updated successfully. Now, I have focussed the question on the bigger problem. For WMP11, H&S, and Search, I click it once, get a busy icon for a second, and then nothing happens. Refer to EDIT1 for other problems. EDIT3: Seems that my problems may be related to some Internet Explorer Script Errors. So what I did was download the IE8 installer from the Microsoft website, but when I run it and get to the main portion of the installer, it just keeps looping on the Downloading step of the installation. The installer is still running, but I left it for at least 4 hours and the downloading step was still not finished. What is the problem? Also, I uninstalled Ubuntu 9.10 after these problems, but they still remain. EDIT4: I'm getting an active desktop recovery background on startup now. And within seconds my computer hangs again. EDIT3 explains main issue though.

• Windows 7 is shutting down unexpectedly, according to the logs.

  - by dlamblin

  Here's a message from my eventvwr EventLog (Windows Logs System): The previous system shutdown at 11:51:15 AM on ?7/?29/?2009 was unexpected. This is funny because I was wondering why the system shut down while I was playing Civilizations IV full screen. Now I know. It was unexpected. Has anyone encountered and resolved this? A little background: I am running Windows 7 RC inside VMWare Fusion 2 (just updated a few months back) on a MacBook (Bitterly not Pro) aluminum-body. Windows 7 occasionally will shut down. This isn't a quick turn-off, it's a shutdown where all the programs are exited, the system waits until they quit (and Civ4 doesn't prompt me to save), it even installed Windows Updates before restarting. And yes it is restarting right after the shutdown. Because I run a game in full screen mode I do not notice any dialog with a countdown timer or anything like that that might be a warning. As I have iStat on my dashboard widgets I can see about 8 temperature monitors. I have seen the CPU get up to 74C before, but during the shutdown, though it seemed hot to the touch (always is), it read 61C for the CPU, 60C for heatsink A, 50C for heatsink B and in the 30s-40s for the enclosure and harddrives. As I type this now, the temps are actually higher, so I don't think the temperature caused it. I have at least six such events dating first from 5/17 which was a week after installing Windows 7. I did find one information level warning from USER32 in the system log that says: The process C:\Windows\system32\svchost.exe (DLAMBLIN-WIN7) has initiated the restart of computer DLAMBLIN-WIN7 on behalf of user NT AUTHORITY\SYSTEM for the following reason: Operating System: Recovery (Planned) Reason Code: 0x80020002 Shutdown Type: restart Comment: And another 15 minutes before that from Windows Update: Restart Required: To complete the installation of the following updates, the computer will be restarted within 15 minutes: - Cumulative Security Update for Internet Explorer 8 for Windows 7 Release Candidate for x64-based Systems (KB972260) Which I think kind of explains it. Though I don't know why restarting after an update would create an error event of "shutdown was unexpected", isn't that pretty odd? Now, how do I set it to never restart after an update unless I click something. Application of solution: As fretje reminded me, there's a couple of configurable settings for this, in windows 7 they're much in the same place as in Windows 2000 SP3 and XP SP1. Running gpedit.msc pops up a window that looks like: Windows 7 has changed the order and added a couple of newer options I've italicized: Do not display 'Install Updates and Shut Down' in Shut Down Windows dialog box Do not adjust default option to 'Install Updates and Shut Down' in Shut Down Windows dialog box Enabling Windows Power Management to automatically wake up the system to install scheduled updates Configure Automatic Updates Specify intranet Microsoft update service location Automatic Updates detection frequency Allow non-administrators to receive update notifications Turn on Software Notifications Allow Automatic Updates immediate installation Turn on recommended updates via Automatic Updates No auto-restart with logged-on users for scheduled Automatic Updates Re-prompt for restart with scheduled installations. Delay Restart for scheduled installations Reschedule Automatic Updates schedule

• How to make Firefox use TCP for DNS

  - by miniBill

  I want to use TCP for DNS, to bypass my ISP's slow and broken DNS servers. I'm not using (and don't want to use) a proxy. Note: I want to use DNS over TCP because if I use it over udp, no matter what server I set, I get answers from my ISP's DNS. Notice that I will fiercely downvote whoever suggests: programs to do TCP over DNS, the setting in about:config to make DNS go over the proxy too: I'm not using a proxy, use another DNS: I've already set up Google as my DNS, but I get intercepted. Example of what I mean by saying intercept: $ dig @8.8.8.8 thepiratebay.se ; <<>> DiG 9.8.1 <<>> @8.8.8.8 thepiratebay.se ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 24385 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;thepiratebay.se.

• BAD DC transfering FSMO Roles to ADC

  - by Suleman

  I have a DC (FQDN:server.icmcpk.local) and an ADC (FQDN:file-server.icmcpk.local). Recently my DC is facing a bad sector problem so I changed the Operation Masters to file-server for all five roles. but when ever i turn off the OLD DC the file-server also stops wroking with AD and GPMC further i m also unable to join any other computer to this domain. For Test purpose i also added a new ADC (FQDN:wds-server.icmcpk.local) but no succes with the old DC off i had to turn the old DC on and then joined it. I m attaching the Dcdiags for all three servers. Kindly help me so that i b able to reinstall new HDD and it can go online again. --------------------------------------- Server --------------------------------------- C:\Program Files\Support Tools>dcdiag Domain Controller Diagnosis Performing initial setup: Done gathering initial info.

I have the server set to a static IP of 10.0.1.70 and for years it has been 192.168.1.70 - the IP apt-get is trying to use right now. I use privoxy and tor thus the 8118 port. Like I said it all worked until I changed the static IP from 192.168.1.70 to 10.0.1.70. I was forced to do so because of router issues. (Long and involved story, I didn't really want to change the IP because I know something like this would happen.) The setup for TOR/Privoxy requires that has you point Privoxy at TOR via 127.0.0.1:9050. Then point curl, etc to Privoxy via $HOME/.bashrc. Typically you would set the listen to IP for Privoxy to 127.0.0.1 but if you want it accessible to the rest of the LAN you set the IP to the server's LAN IP. Which I did a long time ago and was working fine until this morning. I have changed all instances of 192.168.1.70 to 10.0.1.70 in both /etc/privoxy/config and $HOME/.bashrc. What makes this really strange for me is that curl is working fine. I curl icanhazip.com and voila I get a new IP every 10 minutes or so. I curl CNN.com and I get the short but sweet permanently moved to www.cnn.com message I expect. Firefox works fine. Ping works fine. And I've tested all of this via Remote Desktop over my LAN. So the connection appears to be fine for everything except apt. I've also rebooted hoping that would clear 192.168.1.70 from apt. So the connection to the internet and DNS aren't an issue for these programs. And they are, as far as I can tell, using Privoxy/TOR just fine. The real irony here is that I've tried to open up Privoxy to go to Ubuntu's servers directly without going through TOR to speed up the downloads from Ubuntu (did this months ago). So somewhere that I have not been able to find, apt has stored the IP 192.168.1.70. And 192.168.1.70 is no longer valid. Thanks for the help

• How to deny the web access to some files?

  - by Strae

  I need to do an operation a bit strange. First, i run on Debian, apache2 (which 'runs' as user www-data) So, I have simple text file with .txt ot .ini, or whatever extension, doesnt matter. These files are located in subfolders with a structure like this: www.example.com/folder1/car/foobar.txt www.example.com/folder1/cycle/foobar.txt www.example.com/folder1/fish/foobar.txt www.example.com/folder1/fruit/foobar.txt therefore, the file name always the same, ditto for the 'hierarchy', just change the name of the folder: /folder-name-static/folder-name-dinamyc/file-name-static.txt What I should do is (I think) relatively simple: I must be able to read that file by programs on the server (python, php for example), but if I try to retrieve the file contents by broswer (digiting the url www.example.com/folder1/car/foobar.txt, or via cUrl, etc..) I must get a forbidden error, or whatever, but not access the file. It would also be nice that even accessing those files via FTP are 'hidden', or anyway couldnt be downloaded (at least that I use with the ftp root and user data) How can I do? I found this online, be put in the file .htaccess: <Files File.txt> Order allow, deny Deny from all </ Files> It seems to work, but only if the file is in the web root (www.example.com / myfile.txt), and not in subfolders. Moreover, the folders in the second level (www.example.com/folder1/fruit/foobar.txt) will be dinamycally created.. I would like to avoid having to change .htaccess file from time to time. It is possible to create a rule, something like that, that goes for all files with given name, which is on www.example.com/folder-name-static/folder-name-dinamyc/file-name-static.txt, where those parts are allways the same, just that one change ? EDIT: As Dave Drager said, i could semplify this keeping those file outside the web accessible directory. But those directory's will contain others files too, images, and stuff used by my users, so i'm simply try to not have a duplicate folders system, like: /var/www/vhosts/example.com/httpdocs/folder1/car/[other folders and files here] /var/www/vhosts/example.com/httpdocs/folder1/cycle/[other folders and files here] /var/www/vhosts/example.com/httpdocs/folder1/fish/[other folders and files here] //and, then for the 'secrets' files: /folder1/data/car/foobar.txt /folder1/data/cycle/foobar.txt /folder1/data/fish/foobar.txt

• Virtual Network Interface and NAT disables localhost access for MySQL and Apache

  - by Interarticle

  I'm running an Ubuntu Server 12.04, and recently I configured it to do NAT for my laptop. Since the server has only one NIC, I followed instructions online to create a virtual network device (eth0:0) that has a LAN IP address, then further configured iptables and UFW to allow internet sharing. However, just a few days ago, I discovered that one of the PHP pages hosted on the server failed for no apparent reason. A little digging revealed that the MySQL server started refusing connections from localhost. The same happened with a page (PhpMyAdmin) that was configured to be accessible only from localhost (in Apache2). The error, as shown by $mysql --protocol=tcp -u root -p looks like ERROR 1130 (HY000): Host '<host name of eth0>' is not allowed to connect to this MySQL server However, the funny thing is, I configured the mysql server to allow root access from localhost (only). Moreover, the mysql server listens only on 127.0.0.1:3306, as shown by: sudo netstat -npa | head Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN 1029/mysqld which means that the connection could have only come from 127.0.0.1 (Note that MySQL is working because I can still connect to it via unix domain sockets) In effect, it seems that all tcp connections originating from 127.0.0.1 to 127.0.0.1 appear to any local daemon to come from the eth0 IP address. Indeed, apache2 allowed me to access PhpMyAdmin after I added allow <eth0 IP address>. The following are my network configurations (redacted): /etc/hosts: 127.0.0.1 localhost 211.x.x.x <host name of eth0> <server name> #IPv6 Defaults follows .... /etc/network/interfaces: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 211.x.x.x netmask 255.255.255.0 gateway 211.x.x.x dns-nameservers 8.8.8.8 # dns-* options are implemented by the resolvconf package, if installed dns-search xxxxxxx.com hwaddress ether xx:xx:xx:xx:xx:xx auto eth0:0 iface eth0:0 inet static address 192.168.57.254 netmask 255.255.254.0 broadcast 192.168.57.255 network 192.168.57.0 /etc/ufw/sysctl.conf: #Uncommented the following lines net/ipv4/ip_forward=1 net/ipv6/conf/default/forwarding=1 /etc/default/ufw: DEFAULT_FORWARD_POLICY="ACCEPT" #Changed DROP to ACCEPT /etc/init/internet-sharing.conf (upstart script I wrote), section pre-start script: iptables -A FORWARD -o eth0 -i eth0:0 -s 192.168.57.22 -m conntrack --ctstate NEW -j ACCEPT iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT iptables -A POSTROUTING -t nat -j MASQUERADE Note again that my problem here is that programs cannot access localhost tcp services, from the server itself, and that access is blocked because the services have access control allowing only 127.0.0.1. I have no problem connecting (as in TCP connections) to services via tcp, even if the services listen only on 127.0.0.1. I do NOT want to connect to the services from another computer.

• What is a good method to solve cabal install problems?

  - by sp3ctum

  I've used the cabal package manager for Haskell programs to install libraries and new projects that I've cloned from some repositories. More often than not, I keep running into problems. Most projects make installing them seem super easy, but in my case that's not always true - sometimes they are very hard to get running. Some are so hard, in fact, that I've lost interest in the project solely because of not being able to install it. So instead of complaining, I'd like to ask what I should do to better this situation. I'd like to use my most recent problem as an example. I'm interested in trying out the Gitit project. It's a promising looking personal wiki that runs on various version control systems. So here's what I've done: Clone from Github run cabal install in the project directory like I'm told on the project install page: mika@eka:~/git/gitit$ ls BLUETRIP-LICENSE CHANGES HCAR-gitit.tex LICENSE Network README.markdown RELANN-0.6.1 Setup.lhs TANGOICONS YUI-LICENSE data expireGititCache.hs gitit.cabal gitit.hs plugins mika@eka:~/git/gitit$ cabal install Resolving dependencies... cabal: cannot configure happstack-server-7.0.7. It requires base64-bytestring ==1.0.* For the dependency on base64-bytestring ==1.0.* there are these packages: base64-bytestring-1.0.0.0. However none of them are available. base64-bytestring-1.0.0.0 was excluded because gitit-0.10 requires base64-bytestring ==0.1.* mika@eka:~/git/gitit$ So now I'm thinking: well, I'll install happstack-server on its own, maybe that will work: mika@eka:~/git/gitit$ cabal install happstack-server Resolving dependencies... Warning: happstack-server.cabal: Ignoring unknown section type: test-suite Configuring happstack-server-7.0.7... cabal: At least the following dependencies are missing: blaze-html ==0.5.*, hslogger >=1.0.2, monad-control ==0.3.*, network >=2.2.3, sendfile >=0.7.1 && <0.8, system-filepath >=0.3.1, text >=0.10 && <0.12, threads >=0.5, transformers-base ==0.4.* cabal: Error: some packages failed to install: happstack-server-7.0.7 failed during the configure step. The exception was: ExitFailure 1 So looks like there are some dependencies missing. But isn't installing these dependencies the whole point of using cabal in the first place? What should I do? File bug reports (to which project?), install the dependencies manually or something else? Bonus points for explaining what causes these kinds of problems.

• xterm not wrapping text properly

  - by mulllhausen

  I'm configuring both my gnome-terminal and xterm columns (i still haven't picked which of these I will be using) and I have a couple of issues I would like to fix: the typing area seems to be smaller (fewer columns) than the display area the typed text is not wrapping to the next line when it reaches the end - it just continues back around on the same line, overwriting the prompt (i have set a custom bash prompt with PS1 in case this is relevant) $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 7.1 (wheezy) Release: 7.1 Codename: wheezy $ echo $TERM xterm $ stty -a [peter@pc ~] $ stty -a speed 38400 baud; rows 52; columns 126; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = M-^?; eol2 = M-^?; swtch = M-^?; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0; -parenb -parodd cs8 hupcl -cstopb cread -clocal -crtscts -ignbrk brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl ixon -ixoff -iuclc ixany imaxbel iutf8 opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke $[peter@mine ~] $ # the column width only goes up to here ------------------------------------------------> the results are identical in both the xterm and in gnome-terminal 3.4.1.1 and as you can see, the output of the stty -a command goes right up to the edge of the screen, while the typing does not go that far. I have found that I can get the desired result by setting the columns to a very large number, eg: $ stty cols 1800 this fixes both problems. Is it the right way to go about solving this problem? Will this "break" any of the output from programs? So far I have tried top and stty -a and these seem OK. more info as requested in the comments i found that if i cat some input into a file then the columns actually strech the full width of the terminal window: [peter@mine applications] $ cat > /tmp/asd aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaasssssssssssssssssssssssssssssssssssssssssssssssssssssssssssqqqqqqqqqqqqqqqq qqqq does this imply that it is actually bash that is restricting the number of columns and not the terminal? if so then how to alter the number of columns in bash?

• How do I get the latest FastCGI and PHP versions to peacefully coexist on IIS 6?

  - by BHelman

  I have been going round and round trying to get any sort of PHP running on IIS 6. I somehow managed to successfully get version 5.1.4 running using the php5isapi.dll file. However, I want to upgrade a website to begin using a Content Management System. I have never dug into CMS before so I'm open to programs that are easy to use. I am currently looking into TomatoCMS and ImpressCMS - but that's beside the point. I have never done an installation with PHP before and I think I'm getting familiar with how it works. However the current situation is this. Microsoft's Web Platform Installer 2.0 installed FastCGI for me. I need to upgrade to PHP 5.3.1 for a CMS system. So I downloaded the Windows installer and let it go at it. After consulting several other blog articles, I believe I know how it is supposed to work but I am currently not having luck. THE SETUP *.php is a registered extension in IIS 6 for all websites (on Win 2k3). The application that it calls is C:\Windows\system32\inetsvr\fcgiext.dll, like it should. The fcgiext.ini config has the proper lines: [Types] php=PHP [PHP] ext=C:\program files\PHP\php-cgi.exe And the php.ini file also has the correct configs. All extensions are disabled and I changed the correct things for FastCGI. And everything is registered correctly with the PATH variable. Everything is exactly how it should be. BUT when I launch the "info.php" page () on another computer, I get the following error: FastCGI Error The FastCGI Handler was unable to process the request. Error Details: * Section [PHP] not found in config file. * Error Number: 1413 (0x80070585). * Error Description: Invalid index. HTTP Error 500 - Server Error. Internet Information Services (IIS) A quick Google search reveals that I have it all setup correctly as far as the INI's go and the mapping of the php extension. I am completely at a loss. Does anyone have any suggestions? Although the server is hosting three small websites, I don't really care what I have to do to it to get it to work.

• Is dual-booting an OS more or less secure than running a virtual machine?

  - by Mark

  I run two operating systems on two separate disk partitions on the same physical machine (a modern MacBook Pro). In order to isolate them from each other, I've taken the following steps: Configured /etc/fstab with ro,noauto (read-only, no auto-mount) Fully encrypted each partition with a separate encryption key (committed to memory) Let's assume that a virus infects my first partition unbeknownst to me. I log out of the first partition (which encrypts the volume), and then turn off the machine to clear the RAM. I then un-encrypt and boot into the second partition. Can I be reasonably confident that the virus has not / cannot infect both partitions, or am I playing with fire here? I realize that MBPs don't ship with a TPM, so a boot-loader infection going unnoticed is still a theoretical possibility. However, this risk seems about equal to the risk of the VMWare/VirtualBox Hypervisor being exploited when running a guest OS, especially since the MBP line uses UEFI instead of BIOS. This leads to my question: is the dual-partitioning approach outlined above more or less secure than using a Virtual Machine for isolation of services? Would that change if my computer had a TPM installed? Background: Note that I am of course taking all the usual additional precautions, such as checking for OS software updates daily, not logging in as an Admin user unless absolutely necessary, running real-time antivirus programs on both partitions, running a host-based firewall, monitoring outgoing network connections, etc. My question is really a public check to see if I'm overlooking anything here and try to figure out if my dual-boot scheme actually is more secure than the Virtual Machine route. Most importantly, I'm just looking to learn more about security issues. EDIT #1: As pointed out in the comments, the scenario is a bit on the paranoid side for my particular use-case. But think about people who may be in corporate or government settings and are considering using a Virtual Machine to run services or applications that are considered "high risk". Are they better off using a VM or a dual-boot scenario as I outlined? An answer that effectively weighs any pros/cons to that trade-off is what I'm really looking for in an answer to this post. EDIT #2: This question was partially fueled by debate about whether a Virtual Machine actually protects a host OS at all. Personally, I think it does, but consider this quote from Theo de Raadt on the OpenBSD mailing list: x86 virtualization is about basically placing another nearly full kernel, full of new bugs, on top of a nasty x86 architecture which barely has correct page protection. Then running your operating system on the other side of this brand new pile of shit. You are absolutely deluded, if not stupid, if you think that a worldwide collection of software engineers who can't write operating systems or applications without security holes, can then turn around and suddenly write virtualization layers without security holes. -http://kerneltrap.org/OpenBSD/Virtualization_Security By quoting Theo's argument, I'm not endorsing it. I'm simply pointing out that there are multiple perspectives here, so I'm trying to find out more about the issue.

• SQL Server 2008 R2 upgrade fails on upgrade rule check

  - by Tim

  I'm trying to upgrade an evaluation instance of SQL Server 2008 to a fully licensed instance of SQL Server 2008 R2. I made it most of the way through the installer, but I'm getting stopped at the Upgrade Rules page - the SQL Server Analysis Services Upgrade Service Functional Check is failing. The specific error I get: Rule "SQL Server Analysis Services Upgrade Service Functional Check" failed. The current instance of the SQL Server Analysis Services service cannot be upgraded because the Analysis Services service is disabled or not online. Please start the service and then run the upgrade rules check again. Simple enough - just need to start the service. Here's where it gets troublesome. When I open Services and go to start the SQL Server Analysis Services (MSSQLSERVER) service, it provides me the following message: The SQL Server Analysis Services (MSSQLSERVER) service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs. Trying from the command line as Administrator yields: PS C:\Windows\System32 net start MSSQLServerOLAPService The SQL Server Analysis Services (MSSQLSERVER) service is starting... The SQL Server Analysis Services (MSSQLSERVER) service could not be started. The service did not report an error. More help is available by typing NET HELPMSG 3534. I've tried changing the logon setting of this service to Administrator, a user with admin privileges, and both the Local System and Network Service accounts - nothing works. In addition, when I look at the service through the SQL Server Configuration Manager (also run as Administrator), attempting to change the logon setting for the service results in the message: The server threw an exception. [0x80010105] I have no need for analysis services themselves - all I need is for this one service to be running long enough to do the R2 upgrade, then it can shut down again. Any thoughts on how to get the Analysis Services service running? Update: Checking the event log, I found an error logged to the Application log from the MSSQLServerOLAPService. It has event ID 0, task category (289), and says: The service cannot be started: XML parsing failed at line 1, column 4: Unrecognized input signature.
