• Programming a trading strategy

  - by Rob

  Excuse me if I'm not descriptive enough, as I do not have much of a background when it comes to these things: How would I go about coding a primitive trading strategy and link it to some sort of artificial trading environment? Where do I start, and what are some other essential questions I should be asking? I am interested more in doing this because it interests me than making returns. Ideally it utilizes random/historical market data and doesn't actually execute any real trades. My background: I'm almost done my undergrad degree in computer science, and have had intro finance and economic courses. Familiar mostly with C and Java.

• System stuttering caused by hard drive

  - by LukLed

  My system keeps freezing for about 1-2 second every time I try to do something. For example, when I enter URL in browser, it freezes and starts working after few seconds. It is probably related to hard drive. I installed HD tune and when benchmark is in progress, causing constant disk use, everything works fine in background, there are no lags. What can be the reason of this issue? My hardware is Acer Aspire 7740G-6969 running on Windows 7.

• What package (helper app) does recoll need to index images?

  - by hobs

  The File->Show_missing_helpers menu item in the recoll GUI mentions the following missing helper (among others): Perl::Image::ExifTool (image/gif image/jpeg image/png image/tiff image/x-xcf) Per the recoll user manual I installed the perl image exif tool (and library): sudo aptitude install libimage-exif-perl libimage-exiftool-perl but recoll still lists the missing helper and fails to index images. uname -a: Linux AlSSD 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

• Does performing a System Refresh keep these folders?

  - by crayzeedude

  Alright, let's make this simple. I'm really contemplating performing a system refresh. What I've been looking for all over is if the process keeps some certain folders. Namely my Documents, Pictures, Videos, Downloads, and Desktop folders. There's some real valuable stuff in there, and I really want to know if refreshing my PC will keep these intact. Also, there is an application located at C:\Pesterchum that I would like to keep intact. Should I back it up, then copy it back into its original location after the refresh? Or will it be left untouched?

• APC has no system cache entries

  - by lazzio

  I have 2 web servers to provide PHP websites. One server is : Apache + PHP-FPM + APC The other : Apache with MPM-itk + APC. For both of these servers, APC has no cache system entries but only users cache entries as you can see on the screenshot. APC with only users cache entries APC configuration is : apc.cache_by_default 1 apc.canonicalize 1 apc.coredump_unmap 0 apc.enable_cli 0 apc.enabled 1 apc.file_md5 0 apc.file_update_protection 2 apc.filters apc.gc_ttl 3600 apc.include_once_override 0 apc.lazy_classes 0 apc.lazy_functions 0 apc.max_file_size 2 apc.mmap_file_mask apc.num_files_hint 1000 apc.preload_path apc.report_autofilter 0 apc.rfc1867 0 apc.rfc1867_freq 0 apc.rfc1867_name APC_UPLOAD_PROGRESS apc.rfc1867_prefix upload_ apc.rfc1867_ttl 3600 apc.shm_segments 1 apc.shm_size 256 apc.stat 1 apc.stat_ctime 0 apc.ttl 7200 apc.use_request_time 1 apc.user_entries_hint 4096 apc.user_ttl 7200 apc.write_lock 1 Does anyone know why APC acts like this and how to make it work well ? Thank you for your help!

• Why does DirectX use a left-handed coordinate system?

  - by greyfade

  I considered posting on Stack Overflow, but the question strikes me as being far too subjective since I can't think of a reasonable technical explanation for Microsoft's choice in this matter. But this question has bugged me for so long and the issue keeps coming up in one of my projects, and I have never actually seen an attempt at explaining this: OpenGL uses a right-handed coordinate system, where the +Z part of the world coordinate system extends toward the viewer. DirectX uses a left-handed system where the +Z part of the world coordinate extends into the screen, away from the viewer. I never used the Glide API, so I don't know how it worked, but from what I can gather, it uses a left-handed system as well. Is there a technical reason for this? And if not, is there some conceptual advantage to a particular handedness of a coordinate system? Why would one choose one over the other?

• Most common Apache and PHP configuration for portable Web Applications

  - by Mahan

  I always create web application using PHP but I always distribute and deploy my works to different kinds of server platforms and web server configurations. Thus I always encounter problems in deployment because some features are enabled and others are disabled. And my question, is there a standard web server configuration that is commonly used by most of web servers worldwide? covering the aspects of reliability, security and maintainability?

• Linux- passwordless ssh from system (root) script

  - by redmoskito

  What's the easiest way to have a system script (running as root) execute remote commands over ssh? I've written some scripts that execute commands remotely via ssh, and they work great when I run them as myself, as I've set up ssh-agent and keys for passwordless login. I'd like to call these when my laptop docks and undocks. I've been successful at running arbitrary scripts when docking/undocking, but since the ACPI event scripts run as root, trying to run my ssh script fails during authentication. I tried using sudo with the -u and -i flags to simulate running the script as my user, e.g.: sudo -u redmoskito -i /home/redmoskito/bin/remote_command which successfully finds my private key and tries to use it, but the ssh-agent credentials are still missing, so it still needs my passphrase.

• Terminal Server 2003 Login Issue - Insufficient system resources exist to complete the requested ser

  - by LP

  Afternoon. We have three identical terminal servers running Windows Server 2003 SP2, on these servers there are about 250 concurrent users logged on. We're running Roaming Profiles on a central server running Active Directory which cache the profiles locally on each terminal server as well. When one, and just that one, user tries to login she gets this error message (roughly translated from Swedish): "You could not be logged in becouse your principle could not be registered. Check that you're connected to the network or ask your administrator Insufficient system resources exist to complete the requested service." Anyone have an idea about this? I'm stumped ... Best Regards LP

• Why is my system using port 4?

  - by Kathleen

  I have Windows 7 and have noticed that my system is using port 4 to connect to a lot of different IP addresses. When it connects to them it is not for very long before it moves to another IP address. One night I sat and wrote down as many as I could and started checking whois to see where they were and they were from all over the world. I don't understand this. When I did a search on the net with this question. The only info I could come up with was, that port 4 is used by the US Army and a list of port assignments listed it as "unassigned". If anyone has any clues to what is going on... I would greatly appreciate any info I could get.

• Ubuntu 10.04 LTS Minimal requirements (special)

  - by BDX

  I have a PC with 512MB of RAM, an Intel Pentium 4 processor(2GHz), SiS 651 video card(32MB) and a SiS C-Media AC'97 sound controller. I know that my video card is not and will not be supported for Linux. But I wonder if my PC is able to install and start Ubuntu, not just 10.04 LTS, because I'm willing to download 12.04 LTS when it's released. Will unity work? I searched on the internet but I couldn't find a good answer. Thanks in advanced.

• Minimal backup for Windows 7 system recovery [migrated]

  - by JIm

  There might not be an answer to this, but for a home Win7 system, what files/directories must be backed up to recover after a windows crash? I can reinstall software, and I keep data files elsewhere. When I use acronis home backup software to backup my "critical" files it seems to choose the entire partition. Updates are mostly browser cache files and the like. Or, after a crash, should I just reinstall windows. I dread the hours of windows updates that would require. Thanks.

• Ubuntu Server 11.10 AMD64: Installation of graphical desktop changes kernel!?

  - by MindGap

  I've a Ubuntu Server 11.10 amd64 installation that needed a graphical desktop to execute some visual apps. While searching for the correct way to achive this, I noticed that there was a lot of people saying that invoquing the gnome desktop installation (apt-get install ubuntu-desktop) would switch from server to desktop kernel. Is this true!? I've checked and the kernel seems to remain unchanged after the install. I need to be sure of this because the desktop flavoured kernel doesn't seem to support the ServeRaid 8K controller sitting on my IBM server and I have no ideia on how to enable support for it. (I'll be grateful if someone could point me a good guide on how to install ubuntu when the storage controller is not detected) Any comment on this matter will be greatly appreciated! Good linuxing!

• Ubuntu freezes while working

  - by webid4me

  Ubuntu on my laptop has frozen multiple times in last 6-7 months. Its not frequent but I can not relate the freezing to anything which I was doing. Today it froze again when I was taking notes in class - approximately at 12:00 PM. During the freeze both mouse and keyboard stopped working. I tried Alt-Ctrl-F1, Alt-Ctrl-F2 etc without any success. After that I waited few minutes & then I restarted the laptop. I checked /var/log/syslog and /var/log/kern.log and it seems that it did not log anything (I was not able to understand most of it). Please let me know if you can find something unusual at around 12:00 PM. Is there any other log which might be useful? Here are the /var/log/syslog and /var/log/kern.log files.

• A more reliable and more flexible sp_MSforeachdb

  - by AaronBertrand

  I've complained about sp_MSforeachdb before. In part of my "Bad Habits to Kick" series in 2009-10, I described how I worked around its sporadic inability to actually process all of the databases on an instance: http://sqlblog.com/blogs/aaron_bertrand/archive/2010/02/08/bad-habits-to-kick-relying-on-undocumented-behavior.aspx I lumped this in a "Bad Habit" category of relying on undocumented behavior, since - while the procedure does have rampant usage - it is, in fact, both undocumented and unsupported....(read more)

• Hard drive self monitoring system

  - by Hoorayo

  I have a 500GB HDD on my desktop, and there are two partitions as C and D. The computer would not start and shows me a error message. Notice - Hard drive self monitoring system has reported that a parameter has exceeded its normal operating range. Dell recommends you that you back up your data regularly. A parameter out of range may or may not indicate a potential hard. So I took the hdd out of the desktop and made a USB external HDD. My laptop recognizes the hard drive as “I” drive and “J” drive. I am able to click “J” and see folders and files. But there is no response when I click “I” while it makes weird clicking sound. Can anyone explain why I drive doesn't work while J drive works on same physical hard drive? Is there anyway that I can fix?

• Turning a running Linux system into a KVM instance on another machine

  - by Charles

  I have two physical machines that I wish to virtualize. I can not (physically) plug the hard drives from either machine into the new machine that will act as their VM host, so I think that copying the entire structure of the system over using dd is out of the question. How can I best go about migrating these machines from their hardware to the KVM environment? I've set up empty, unformatted LVM logical volumes to host their filesystems, with the understanding that giving the VMs a real partition to work with achieves higher performance than sticking an image on the filesystem. Would I be better off creating new OS installs and rsyncing the differences over? FWIW, the two machines to be VM'd are running CentOS 5, and the host machine is running Ubuntu Server 10.04 for no particularly important reason. I doubt this matters too much, as it's still going to be KVM and libvert that matter.

• Enterprise Data Center System Admin/Engineer to Server Ratio

  - by Bob

  I know there have been similar questions asked over the last few months however looking at a Data Center Operations and know there are some really smart people out there that might be able to help. Looking for some staffing best practices based on first hand experience and was hoping that there is some experience in this area that can provide "best practice" application: Three High Availability (99.99% plus) Enterprise Level Data Centers geographically dislocated, one manned 24x7x365, one lights out, one co-location running HOT-HOT-HOT supporting a global community. More than 2,000 operating systems consisting of 95% Windows, 5% Linux and Solaris, 45% virtualized, more than 100TB storage. No desktop support, no Network Administration (administrated separately), running N+1 and serving more than 250 Billion page views annually. Based on experience what has been your experience with Server to "Data Center System Administrator/Engineer" ratio? Thanks in advance for your responses.

• Synchronizing Mysql Table Schema [on hold]

  - by user1122069

  I have some difficulty keeping track of my SQL changes in a text file in SVN. One solution that I am aware of is to put the SQL queries in files (1.sql, 2.sql...) and to manually load each file at the proper time. Besides missing commas, the process is too cumbersome when builds become more frequent. I have actually taken to asking a co-worker to send me his SQL changes on Skype and we just apply the changes immediately on our local, development, and production servers (using three PhpMyAdmin tabs). I have seen several GUI tools mentioned in similar questions on SO, but these are actually more work and less automated than the aforementioned methods. Is there any standardized process by which this is done in an automated way? I can only guess that large companies build their own mechanisms of keeping track of database schema changes (yet I can't find a word about it - maybe they use files?). This question was closed as off-topic on Stack Overflow, so I am re-posting it here.

• Do control groups improve system performances?

  - by qdii

  According to this website, enabling cgroups in the kernel can boost performances by sharing resources in a better way. In particular, the conclusion states that:  Nevertheless, with a little trial and error, cgroups can help you improve the efficiency of your systems’ resource usage and avoid downtime due to overusage of a single service. Kernel seeds, however, recommend to deactivate them altogether. They say: Consider these [kernel] settings poison. They remain nothing but system slow-downs. They are all off by default [in the proposed kernel config file]. Who should I trust?

• IIS is not accepting connections after WIndows system update

  - by user78102

  I've been running a web site for the past year on Windows Home Server 2008 R2. After the March 2012 system updates, the site is no longer accessible to clients. They see this error: website is online but isn't accepting connections. Ping tests to the FQDN of the server are successful and NSLOOKUP returns the correct result. The Internet connection tests out good from the server. I have not changed my internet connection (Comcast Business Internet) or my router configuration (I forward incoming requests from the outside to port 80 of the local IP address of the server). I have tried: Disabling the Windows Firewall. Rebuilding the OS and configuration. I still have the problem. How can I resolve this?

• Low Level Software and Devices

  - by user271619

  I'm looking at a new chapter in my career. I'm a web developer, but now I'm starting to play around with C, compilers, and things I didn't have to work with before. It's all very intriguing! As I'm getting more and more into the "lower level" arena, I'm wondering how devices (mice, printers, webcams, microphones, etc...) are controlled, managed, detected, or used in general with software. I ask because I'm really having a hard time finding straightforward documentation online describing or giving examples of how hardware interacts with software. Does someone know of decent sites that can get me started learning this?

• Open source Entity-Component game [on hold]

  - by Papavoikos

  I've been reading a lot about entity-component design but every article talks about the philosophy behind such design, leaving a lot of details and implementations outside. I'm looking for an open source game that uses the entity-component design so I can study the concrete implementations and see how they deal with things such as How (and if) they deal with inter-component communication How much logic each component has or doesn't have How a subsystem can change it's behavior depending on an entity's state (the screen darkens depending on the player's health)
