  • Benchmarking CPU processing power

    - by Federico Zancan
    Provided that many tools for computers benchmarking are available already, I'd like to write my own, starting with processing power measurement. I'd like to write it in C under Linux, but other language alternatives are welcome. I thought starting from floating point operations per second, but it is just a hint. I also thought it'd be correct to keep track of CPU number of cores, RAM amount and the like, to more consistently associate results with CPU architecture. How would you proceed to the task of measuring CPU computing power? And on top of that: I would worry about a properly minimum workload induced by concurrently running services; is it correct to run benchmarking as a standalone (and possibly avulsed from the OS environment) process?

  • Understanding how to create/use textures for games when limited by power of two sizes

    - by Matthias Reisner
    I have some questions about the creating graphics for a game. As an example. I want to create a motorbike. (1pixel = 1centimeter) So my motorbike will have 200 width and 150 height. (200x150) But the libgdx only allows to load sizes with the power of 2?! (2,4,8,16,...) First I thought about that way. I will create my bike with the size (200x150) and save it as png. Than I will open it again (e.g. with gimp) resize the image to a size which uses values with power of 2 (128x128). I will load that as texture in the programm and set width as 200 and height as 150. But wouldn't it be a problem? Because I will lose some pixel information when I make the first conversation.?! Isn't it?

  • Can't boot after power failure - 14.04 - GRUB even doesn't showup

    - by Nateowami
    Packages were updating when somehow the power failed (battery fully charged and power got disconnected). Now it won't boot. It doesn't even get as far as GRUB. The bios says it can't boot and press any key to retry. Fortunately all data is backed up and I can boot a live SD. Now what do I do? Model: Dell Latitude D630 Dual-boots with Windows 7, but since GRUB doesn't show up that's not bootable either. Thanks in advance for any help!

  • Lenovo u400, Ubuntu 12.04. Sudden reboots / power down

    - by Victor Neo
    I've recently bought a Lenovo u400 (http://www.lenovo.com/products/us/laptop/ideapad/u-series/u400/) and installed Ubuntu 12.04 on it. Everything works fine (I've installed the proprietary ATI drivers for switchable graphics) except that I get a random power down or reboot either while surfing the web or watching videos. Monitoring the temperature with sensors, the laptop never goes into any critical zone but still may power down or reboot once in a while. Is there any logs that I should check and any particular message I should take note of? EDIT: This happens to me as well. This also happens without proprietary drivers activated.

  • Unleash the Power of JavaFX

    - by Angela Caicedo
    It seems that it was just yesterday that we were getting ready for JavaOne 2012.  Now it's over, but it's definitely a great time to go back and watch the sessions you missed, and learn some of the latest news about Java.   For this JavaOne, I presented two sessions and one HOL, all of them related to JavaFX: JavaFX Extreme GUI Makeover Building JavaFX Interfaces with the Real World Unleash the power of JavaFX If you couldn't join us for these sessions, just follow the links and you can watch the videos on demand. For the HOL I've created a repository at GitHub, as many of the attendees wanted to keep the material.   In this repository you can find the lab document, the NetBeans projects for each exercise and it's appropriate solution.  Hope you enjoy! I created and presented a HOL called:  Unleash the power of JavaFX.  In this blog entry I would like to provide you

  • Lost power during upgrade, how do I recover?

    - by Ryan McClure
    I was attempting to update my 11.10 install to 12.04beta. During the install step, I accidentally lost power to my laptop (the power cable came unplugged) and it shut down. Whenever I go to boot now, I can select my install via Grub and it loads up to where the sign-in should happen, but I get a display that looks like what you see as soon as you shut down. It looks like it locks after checking for the battery. Is there anyway, with or without Live media, to restore my machine's install/update to 12.04 but still keep my settings/applications/files?

  • Is text-only mode a saving or a problem for battery savings?

    - by Robottinosino
    A friend is flying to the US from Europe and asked me a very thought-provoking question, which I am not remotely able to answer with substance so I am asking it here: How to absolutely maximise battery life on an Ubuntu (laptop) install? do not rush to mark this as duplicate, there is an important point here: does -GNOME- help or worsen battery life? Let me provide some context: The only task he needs to perform is: edit text files in Vim. He is unsure whether running GNOME will drain his battery life more or actually save him some battery life given the smarts of GNOME's power management features like "switch this peripheral to -power save- after X minutes..." (GNOME might just be a configuration front-end for settings that are governed by command-line utils for all I know?) He could perfectly well boot the system in text-only mode and use the automatic 6 virtual consoles for his needs, if that's a saving at all over running tmux (I think so because of all the smart buffering/history/etc the latter does by default?) Exactly how would you advise him to run his laptop during his flight? What I told him already: power off WiFi in the BIOS, not from the "GUI" power off Bluetooth switch off the courtesy light and use low monitor brightness play music off of his phone, not mp3blaster do not use his tiny portable mouse (and do not attach any other USB gimmicks like "screen light", etc) stop development services he will not be using, especially apache2, tomcat, dovecot, postgresql, etc. Potentially: - switch off his cron jobs? (he does an rsync + tar + 7za of his "work in progress" every so often) I think the above is standard stuff one could get off StackExchange, and with many duplicates... the core of this question is, I think: __ will running Ubuntu in text-only mode be a saving in terms of battery life or a problem? why? (provide some technical arguments) __ I think it will be a saving but I am also scared about "other things" detecting and enabling advanced chipset power management features only when some services are started.. and fear these "services" may be off in text-only mode?

  • Restricted Flow Of Power

    - by user13827
    I'm sure all is fine, but i need some reassurance. Last month my company launched consolidated two of their websites into one new website. www.fdmgroup.com and www.fdmacademy.com into a newly designed www.fdmgroup.com. Because the FDM Academy grew as it's own brand we decided not to just forward the domain to the fdmgroup website, but instead just mirror the new FDM Group website and use a canonical tags to the FDM Group domain (so the link juice will pass to the FDM Group domain pages) The website has be live for nearly a month and i don't believe any power has passed down through the FDM Group website to it's deeper pages even though 301 redirects from the legacy group and academy domains in place. I am also seeing the same problem on the FDM Academy domain, but i expect to see this as every page has a canonical to the same page on the Is there anything which is restricting the flow of power through the site, or am i just being impatient. Thanks in advance Jon

  • 13.10 Desktop - Stop Suspension on Lid Closure

    - by bpmitche
    I'm having a problem with power management settings on my ASUS K52-F Laptop. Upgraded from 13.04 to 13.10 earlier today; closing the laptop lid puts the laptop into suspension (even on AC Power - tried fixing it in gnome power settings, tried fixing it in Cinnamon power settings, tried changing it in DCONF-Editor, but no matter where I change the setting the laptop lid still suspends). After resuming from suspend, I restore to the gnome window/login manager (instead of Cinnamon login manager). Wifi doesn't reconnect, but the icon in Cinnamon shows that I'm connected. IFCONFIG shows that the interface is up and working normally, but still not reconnecting. ifconfig wlan0 down / up doesn't change anything. Any help would be greatly appreciated.

  • Power scheme faulty [closed]

    - by user40287
    Hi, I use a laptop. When I take the power cable out to run on batteries, the screen darkens, as it is no longer so bright, to save on battery power. When I put the power cable back in, the screen brightens back to it's original brightness. However, I have since replaced the power cable, and the screen remains darkened. How do I regain the original brightness? Thanks, Steve

  • Power Law distribution for a given exponent in C# using MathNet

    - by Eric Tobias
    Hello! I am currently working on a project where I need to generate multiple values (floats or doubles preferably) that follow a power law distribution with a given exponent! I was advised to use the MathNet.Iridium library to help me. The problem I have is that the documentation is not as explicit as it should be if there is any! I see multiple distributions that fit the general idea of the power law distribution but I cannot pinpoint a good distribution to use with a certain exponent as a parameter. Does anybody have more experience in that matter and could give me some hints or advice?

  • Acer Aspire Timeline - Power control application?

    - by th3dude19
    I recently purchased an Acer Aspire Timeline 3810TZ notebook. It comes equipped with 2 modes, one for power saving (screen is dimmer, etc) and another for when connected to a power source. However, I'd like to control the settings for power save mode (specifically to make the screen a bit brighter) but the system didn't seem to ship with an app installed to modify these settings. Browsing the support site proved unsuccessful also. Anything out there I can do to control the notebook's power save settings?

  • Filter zipcodes by proximity in Django with the Spherical Law of Cosines

    - by spiffytech
    I'm trying to handle proximity search for a basic store locater in Django. Rather than haul PostGIS around with my app just so I can use GeoDjango's distance filter, I'd like to use the Spherical Law of Cosines distance formula in a model query. I'd like all of the calculations to be done in the database in one query, for efficiency. An example MySQL query from The Internet implementing the Spherical Law of Cosines like this: SELECT id, ( 3959 * acos( cos( radians(37) ) * cos( radians( lat ) ) * cos( radians( lng ) - radians(-122) ) + sin( radians(37) ) * sin( radians( lat ) ) ) ) AS distance FROM stores HAVING distance < 25 ORDER BY distance LIMIT 0 , 20; The query needs to reference the Zipcode ForeignKey for each store's lat/lng values. How can I make all of this work in a Django model query?

  • Power surge PC damage: How can I test all components of my PC without access to a second computer?

    - by Doug T.
    Ever since we had some crazy power surges last week my 64 bit Windows 7 PC has been acting strange. My USB network adapter disconnects from the wireless and can't detect the signal. I have to disable/reenable the adapter to detect it again. Also my wife has reported that the PC has rebooted a few times while I'm not sitting at it. Today I finally caught the reboot while I was using the PC. I got this blue screen of death. Stop Code 0x00000109: "Modification of system code or a critical data structure was detected." I followed the advice at the linked article and ran a memory test. I used memtest86 and its already found around 300,000 errors out of 8 gigs of ram. Now I'm worried -- what are the odds this is isolated to just my memory and not just a system wide problem? Isn't there a good chance that many other components are fried? More importantly, how can I test those other components? Are there tools similar to memtest I can use to test my motherboard/video card/power supply? If these are vender specific, is it typical for vendors to provide testing tools?

  • Ubuntu 12.04 does not recognize Kingston DT108 16GB memory

  • Can Current Backflow from Powered Hub's Adapter & cause PC Damage?

    - by SuperUserMan
    Getting this short: Can current flow from a powered USB hub's power adapter (lying 10 Meter away) back to computer via usb port and cause damage to Computer components like mobo, etc? What should be my concerns? Using a 2 Amp 5V Power adapter to power a 10m Long Active Repeater USB extension cable with 4 port HUB & plugging into PC's Front port, causes PC Chassis fan to keep running (thought slower than regular speed) Front Chassis HDD & power LED to turn on (though bit dim) may be other things which i cant detect/see at chip level, in motherboard?? All this even after PC is shut down (bit scary) More detail (in case still want to read): To run 4 High power (needing 450 mAmps) Wifi Adapters, far away from PC, Bought Active Repeater USB Extension Cable with 4 Ports & power port at far end http://www.ebay.com/itm/33FT-USB-2-0-Male-to-Female-Extension-Cable-Hub-Splitter-Adapter-with-4-USB-Port-/390846115254 Then added a locally bought 2 Amp 240V AC to 5V DC Power Adapter and plugged into USB hub which is a part of & situated at far end of a 10 Meter Active Repeater usb extension cable. Even 4 Wifi Adapters run fine (appear to) using this setup, but running chassis fan, dimly lighted Power & HDD LED, even when PC is switched off is bit scary and surely mean 5V & some current is flowing all though that 10 meter extension cable into my USB port & powering stuff. Can this cause damage? and what should be my concerns. Of course I can't switch off the power adapter (lying 10 meters away from PC) every time I switch off my PC to prevent this.

  • Why did Embarcadero make me sign a waiver?

    - by Peter Turner
    Just signed in to the Embarcadero Developer Network and got this: EXPORT CONTROLS ON EMBARCADERO SOFTWARE Your EDN membership and access to Embarcadero Software is subject to your agreement to and compliance with the following terms: -You agree that U.S. export control laws govern your use of the Embarcadero Software. -You are not a citizen, national, or resident of, and are not under control of, the government of Cuba, Iran, Sudan, North Korea, Syria, nor any country to which the United States has embargoed or prohibited export. -You will not provide or export Embarcadero Software, directly or indirectly, to the above mentioned countries nor to citizens, nationals or residents of those countries. -You are not listed on the United States Department of Treasury lists of Specially Designated Nationals, Specially Designated Terrorists, and Specially Designated Narcotic Traffickers, nor are you listed on the United States Department of Commerce Table of Denial Orders. -You will not provide or export the Embarcadero Software, directly or indirectly, to persons on the above mentioned lists. -You will not use the Embarcadero Software for, and will not allow the Embarcadero Software to be used for, any purposes prohibited by United States law, including for the development, design, manufacture or production of nuclear, chemical or biological weapons of mass destruction. I think it's BS, but what craziness is forcing companies like Embarcadero to hold developers to these very high standards? Also, what is "Embarcadero Software"? Does that mean I can't put a benign videogame on a website that may have a runtime that might be downloaded by a Iranian who love scrabble. Or does "Embarcadero Software" refer to anything I develop using Delphi.

  • Can computer crashes and reboots mean weak power supply?

    - by TomA
    Recently I replaced the videocard in my PC for a newer, faster one. All games work perfectly but I get random system crashes and reboots. This happens even when the system is almost idle (browsing, playing music). It never happened with the old card. All drivers are up-to-date. Is it possible that the power supply is not powerful enough for the new card?
