• Whole continent simulation [on hold]

  - by user2309021

  Let's suppose I am planning to create a simulation of an entire continent at some point in the past (let's say, around 0 A.D). Is it feasible to spawn a hundred million actors that interact with each other and their environments? Having them reproduce, extract resources, etc? The fact is that I actually want to create a simulation that allows me to zoom in from a view of the entire continent up to a single village, and interact with it. (Think as if you could keep zooming in the campaign map of any Total War game and the transition to the battle map was seamless, not a change of the "game mode"). By the way, I have never made a game in my entire life (I have programmed normal desktop applications, though), so I am really having trouble wrapping my head around how to implement such a thing. Even while thinking about how to implement a simple population simulator, without a graphical interface, I think that the O(n) complexity of traversing an array and telling all people to get one year older each time the program ticks is kind of stupid. Any kind help would be greatly appreciated :) EDIT: After being put on hold, I shall specify a question. How would you implement a simulation of all basic human dynamics (reproduction, resource consumption) in an entire continent (with millions of people)?

• Ubunto 12.10 Boots to purple screen

  - by Ric

  I know this question has been tackled in a couple different threads but I've tried what I could from those and have not resolved the issue. I have just a basic understanding of this system so feel free to talk down to me or explain this like you would to a 5 year old. Let's start from the beginning. My son has a computer built by an IT friend of mine (we moved so he can't help any more). It had Windows XP running on it and it just stopped working correctly. This same friend had built a laptop for me with Ubuntu which I liked so I thought I'd put a new OS on my sons computer and it may work better. I downloaded Ubuntu 12.10 onto a USB drive and loaded it onto his computer. I followed all the prompts, it installed, I restarted the computer, it gives me the option of which OS to pick. I pick Ubuntu and it seemingly loads. The desktop comes up with just the basic pinkish Ubuntu background but that is it. There are no icons. I can't right click anywhere to create a file. Left clicking the mouse does not create a square when moved. Alt + F2 doesn't do anything. I can open a terminal but any of the commands I have seen in previous threads do not correct any issues. What else can I do, or what resources are available to fix this problem? I don't know if there are additional files on the USB drive that I need to access or what. Also, one of the problems we were having with my sons computer is that windows would only load to a blank screen. It runs accordingly in safemode and my install of Ubuntu was through safemode of Windows XP.

• How to package static content outside of web application?

  - by chinto

  Our web application has static content packaged as part of WAR. We have been planning to move it out of the project and host it directly on Apache to achieve the following objectives. It's getting too big and bloating the EAR size resulting in slower deployment across nodes. Faster deployment times. Take the load of Application Server Host the static content on a sub domain allowing some browsers (IE) to load resources simultaneously Give us an option to use further caching such as Apache mod_cache apart from the cache headers we send out to browsers. We use yuicompressor-maven-plugin to aggregate and minimize JS file. My question is how do package and manage this static content out side of the web application? My current options are. New maven war project. Still use the same plugin for aggregation and compression. Just a plain directory in SVN and use YUI/Google compressor directly. Or is there a better technology out there to manage static content as a project?

• Pair Programming, for or against? [on hold]

  - by user1037729

  I believe it has many advantages over individual programming: Pros By pairing senior with relatively junior staff, the more junior can get up to speed with both project and computing experience, and the senior will re-think the problem in order to communicate with the junior, thus re-checking his own thinking (rubber duck principle!). At least 2 people will know about any single piece of work, if one person is away the other can cover, or if some one leaves a project knowledge transfer is easier. Two brains on a complex task is more effective, communication keeps the work free flowing and provides redundancy in decision making. Code is effectively reviewed as its being written, no need for a separate reviewing phase which requires a context switch as someone who has not been working on the piece in question would be required to understand and review the related code. Reviewing code on your own which you haven't written or architected is not fun, hence counter productive. Cons Less bandwith for performing tasks, lets say we have 4 devs, pair programming requires 2 devs per task, so we would be doing 2 tasks concurrently as a posed to 4. I believe this "Con" does not stand up as the pair programmed task would complete sooner and comes with a review built in for free! Ie the pair programming task would be more efficient and thus free up resources earlier. Less flexibility to chop and change tasks as two developers are tied into a task, when flexibility is required this could be a problem.

• How can I configure the embedded wireless card in a Toshiba Satellite Pro 4600 to work under Lubuntu 10.10?

  - by MoLE

  I'm struggling to get the embedded wireless card in this laptop to work. In 7.10 (gutsy) it worked fine. Now I'm trying to get 10.10 (maverick) working on it, and am using the Lubuntu flavour due to the low resources of this laptop. The hardware: Appears to be an embedded pcmcia card. pccardctl ident gives: Socket 0: product info: "TOSHIBA", "Wireless LAN Card", "Version 01.01", "" manfid: 0x0156, 0x0002 function: 6 (network) The default kernel recognises the card and loads the orinoco_cs driver. orinoco_cs 0.0: Hardware identity 0005:0002:0001:0002 orinoco_cs 0.0: Station identity 001f:0001:0006:000e orinoco_cs 0.0: Firmware determined as Lucent/Agere 6.14 Then for some reason, the driver isn't happy with this and gives: orinoco_cs 0.0: Hardware identity 0005:0002:0001:0002 orinoco_cs 0.0: Station identity 001f:0002:0009:0030 orinoco_cs 0.0: Firmware determined as Lucent/Agere 9.48 All seems ok until I try to associate with my access point using Network Manager. eth1: Lucent/Agere firmware doesn't support manual roaming repeated about 10 times then NM gives up. According to the linuxwireless.org wiki page on this driver, this is a known issue, and I quote: Known issues Roaming and WPA_supplicant Lucent/Agere firmware doesn't support manual roaming On the Agere cards, roaming is controlled by the firmware instead of userspace. You will get the above message if userspace attempts to associate with a specific AP rather than by SSID. If you are using wpa_supplicant use ap_scan=2 mode. NetworkManager uses wpa_supplicant, so the above also applies. At this point my google-fu has failed me, and I can't find how to configure network manager to use the mystical "ap_scan=2" mode via wpa_supplicant. I have tried the following suggested solutions (from launchpad or the forums) deleting the agere* files from /lib/firmware using wicd instead of network manager combining both blacklisting the orinoco_cs driver in an attempt to force use of the hostap_cs driver instead (in case it is a prism2 card). Obviously none of them have worked for me. Any hints on how to perform the suggested workaround above? Edit: I have also confirmed working on 8.10 (intrepid) live CD.

• Can certain system-hungry modules be disabled in Ubuntu?

  - by Ole Thomsen Buus

  Hi, Let me add some context: I am currently using Ubuntu 9.10 64-bit (Desktop) on a relatively powerful stationary PC (Intel Core i7 920, 12GB ram). My purpose is highspeed imaging with a pointgrey Grashopper machine-vision camera (for research, PhD project). This camera is capable of 200 fps at full VGA (640x480) resolution. The camera is connected using Firewire (1394b) and the drivers and software from Pointgrey works great. I have developed a console C++ application that can grap a certain number of frames to preallocated memory and after this also save the grapped frames to harddrive. Currently it works fine but sometimes I am observing a few framedrops (1-3). When this happens I reset the experiment and repeat the recording and usually i am lucky the second time with no framedrops (the camera-driver has a internal framecounter that I am using). Question: I usually go to tty1 and use "sudo service gdm stop" to disable the graphical frontend. It seems to release some memory though that is not my main concern. My concern is CPU resources. Are there other system hungry modules that can be disabled temporarily such that the CPU gets less busy on Ubuntu 9.10? At some point in the future I will update to 10.10. Should I perhaps option for the server edition instead? Thanks.

• No MAU required on a T4

  - by jsavit

  Cryptic background One of the powerful features of the T-series servers is its hardware crypto acceleration, which dramatically speeds up the compute intensive algorithms needed to encrypt and decrypt data. Previously, administrators setting up logical domains on older T-series servers had to explicitly assign crypto resources (called "MAU" for historical reasons from the T1 chip that had "modular arithmetic units") to domains that had a significant crypto workload (say, an SSL based web server). This could be an administrative burden, as you had to choose which domains got the crypto units, and issue the appropriate ldm set-mau N mydomain commands. The T4 changes things The T4 is fast. Really fast. Its clock rate and out-of-order (OOO) execution that provides the single-thread performance that T-series machines previously did not have. If you have any preconceptions about T-series performance, or SPARC in general, based on the older servers (which, it must be said, were absolutely outstanding for multi-threaded applications), those assumptions are now obsolete. The T4 provides outstanding. performance for all kinds of workload, as illustrated at https://blogs.oracle.com/bestperf. While we all focused on this (did I mention the T4 is fast?), another feature of the T4 went largely unnoticed: The T4 servers have crypto acceleration "just built in" so administrators no longer have to assign crypto accelerator units to domains - it "just happens". This is way way better since you have crypto everywhere by default without having to manage it like a discrete and limited resource. It's a feature of the processor, like doing an integer add. With T4, there is no management necessary, you just have HW crypto everywhere all the time seamlessly. This change hasn't been widely advertised, and some administrators have wondered why there were unable to assign a MAU to a domain as they did with T2 and T3 machines. The answer is that there is no longer any separate MAU, so you don't have to take any action at all - just leave the default of 0. Summary Besides being much faster than its predecessors, the T4 also integrates hardware crypto acceleration so its seamlessly available to applications, whether domains are being used or not. Administrators no longer have to control how they are allocated - it "just happens"

• Wireless connection disconnects and reconnects with a Netgear WNA1000

  - by William Berkenkamp

  Ever since I made the permanent switch from Vista to Ubuntu i've had wireless connectivity problems. From watching the network manager when it disconnects it seems like it turns off the receiver for some reason. Could it be bad drivers? I used their install software and the site doesn't really offer driver downloads. The adapter is a Netgear WNA1000 if memory serves, and I don't know much about the router except that it's a Motorola Surfboard. And I figure this might help a bit *-network description: Ethernet interface product: RTL8101E/RTL8102E PCI Express Fast Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:01:00.0 logical name: eth0 version: 01 serial: 00:1b:b9:a7:39:a4 size: 10Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm vpd msi pciexpress bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half firmware=N/A latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:40 ioport:d800(size=256) memory:feaff000-feafffff memory:feac0000-feadffff *-network description: Wireless interface physical id: 1 bus info: usb@2:1.1 logical name: wlan0 serial: 00:26:f2:8b:fb:38 capabilities: ethernet physical wireless configuration: broadcast=yes driver=carl9170 driverversion=3.2.0-24-generic-pae firmware=1.9.4 ip=10.0.0.36 link=yes multicast=yes wireless=IEEE 802.11bgn I have tried installing WICD and it didn't fix the problem.

• How much overhead is there in persistent connections?

  - by nynex

  Ok so I'm musing over a little side project I want to start. Essentially its a multi-session web based FTP client. Multi-session in that you can log into several FTP servers at the same time and perform operations like moving a file from one FTP server to another. I'm doing this mainly to brush up on the new webdev technologies, particularly websockets. I'm using node.js + socket.io to keep a persistent bi-directional connection between the web browser and the web server. The web server will also have persistent connections to each FTP server the user has logged into. So if there are 100 concurrent users each logged into 5 ftp accounts, the web server will have 100 websocket connections + 500 ftp connections. Is servicing 600 connections a lot? I know it depends on the hardware resources of the server but is something like this doable on a budget? Are there more efficient means of doing something like this? I know its unlikely that this project will really get popular but I want it to scale well regardless. Thanks for any help, I've still got a lot to learn.

• Opportunities in Cloud Computing

  - by Paul Sorensen

  A recent article from CIO Journal indicates that there is an extreme labor shortage (in certain technology areas) that is is leading to upward pressure on wages for IT Workers. This represents a great opportunity for those with certain skill-sets, among which include Java (Oracle certification is mentioned specifically). The article points out that a key driver of the labor shortage is the expansion of cloud computing. Cloud computing is set up to make life extremely simple for end-users, but the model pushes the complexity to back-end systems which are sophisticated, enterprise-level computing stacks (Oracle has an extensive set of cloud computing solutions). These complex systems require very highly-skilled IT professionals (the best-of-the-best) to successfully develop, implement, administer and maintain them. What this mean for you is that there is opportunity for those who have the appropriate skills at the appropriate levels. If you want to be a part of this opportunity you should do a self-assessment of your own skill-sets and experience. Based upon your results you can decide where it would be most appropriate to spend your time and resources for the highest return on your investment. By expanding and sharpening your skills and by gaining greater experience you will be better prepared to take advantage of career opportunities (like this) that come along periodically. As you evaluate your needs remember that Oracle University has a tremendous selection of high-quality eduction offerings (including training and certification) that can you help move your career forward. Thanks and best of luck!

• Turn O&M Operations into Optimized Projects with Oracle Primavera

  - by mark.kromer

  Oracle enterprise project portfolio management with Primavera is much more than optimizing project performance and eliminating project failure on new projects, capital programs, etc. A very common use case that we see is small-scale frequent and recurring projects based on on-going operations and maintenance. As opposed to assigning resources to various activities when you are building a new network infrastructure, for example, Oracle has teamed-up the Primavera and eBusiness Suite teams to provide direct integration for work orders from Oracle's Enterprise Asset Management (eAM) system to populate into Primavera P6 project schedules. So now that your network infrastructure build-out project is complete, planners and operations managers can use the world-class what-if and scheduling capabilities in Primavera tools to assign work orders, maximize resource utilization and to reuse templates for typical O&M operations in Primavera and share that back to the operations teams using eAM for maintenance. Also, large-scale maintenance operations related to large assets in the asset lifecycle will include phase-outs, shutdowns and turn-arounds which are classic maintenance projects, as opposed to building something new, that Oracle Primavera with Oracle e-Business Suite provides full coverage to optimize your ALM processes in your business. Read more about these new capabilities from Oracle in the ERP space from the Oracle eAM data sheet.

• Google Chrome on Ubuntu 12.04 not rendering webpages correctly

  - by sumit_gt

  I am facing some serious web page rendering issues with Chrome. It is more prominent during javascript based animations and stuff on websites like youtube. I have tried removing chrome using (sudo apt-get purge google-chrome-stable) and then reinstalling it. But the problems still persist. The same webpages work correctly on firefox on ubuntu and chrome on windows. The problem only shows up when I use chrome on ubuntu. I think the issue has started after I updated to the latest version of Chrome. I have used Chrome previously on this machine without any problems. I have attached a image that demonstrates the issue. What could possibly be the problem?

• How to indicate to a web server the language of a resource

  - by Nik M

  I'm writing an HTTP API to a publishing server, and I want resources with representations in multiple languages. A user whose client GETs a resource which has Korean, Japanese and Trad. Chinese representations, and sends Accept-Language: en, ja;q=0.7 should get the Japanese. One resource, identified by one URI, will therefore have a number of different language representations. This seems to me like a totally orthodox use of content negotiation and multiple resource representations. But when each translator comes to provide these alternate language representations to the server, what's the correct way to instruct the server which language to store the representation under? I'm having the translators PUT the representation in its entirety to the same URI, but I can't find out how to do this elegantly. Content-Language is a response header, and none of the request headers seem to fit the bill. It seems my options are Invent a new request header Supply additional metadata in a multipart/related document Provide language as a parameter to the Content-Type of the request, like Content-Type: text/html;language=en I don't want to get into the business of extending HTTP, and I don't feel great about bundling extra metadata into the representation. Neither approach seems friendly to HTTP caches either. So option 3 seems like the best way that I can think of, but even then it's decidedly non-standard to put my own specific parameters on a very well established content type. Is there any by-the-book way of achieving this?

• Dim (NEARLY blank) laptop screen, secondary screen works - why?

  - by LIttle Ancient Forest Kami

  My laptop screen is (almost) black while my secondary screen is fine. I believe it to be backlight / brightness related. Problem description it starts when I start the laptop system loads and works fine, just screen has problems I can see the screen though very faintly / dimly - it's hard to see anything which ain't very white e.g. starting screen has big Thinkpad logo in white, large font - I can see it, though very dimly second screen works very well Official backligtht debugging: using acpi setting as prescribed there for Thinkpads didn't help I can see an entry in /sys/class/backlight/ and it changes when I press hotkeys for brightness (current backlight power for instance goes up or down) acpi-off didn't helpm neither did acpi_backlight=vendor Hardware data Laptop is Thinkpad Edge with glossy screen. 4 processors, 2 cores, exemplary CPU data from cat /proc/cpuinfo reports Genuine Intel i5 (M 480 @ 2.67GHz). OS is Ubuntu Lucid, 10.04 LTS, 64-bit, with Linux generic kernel (2.6.32-44) and GNOME 2.32.2 (though I doubt there lies the problem). $ lspci | grep VGA 01:00.0 VGA compatible controller: ATI Technologies Inc M92 [Mobility Radeon HD 4500 Series] $ lshw -C display *-display description: VGA compatible controller product: M92 [Mobility Radeon HD 4500 Series] vendor: ATI Technologies Inc physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 32 bits clock: 33MHz capabilities: pm pciexpress msi bus_master cap_list rom configuration: driver=radeon latency=0 resources: irq:33 memory:c0000000-dfffffff(prefetchable) ioport:2000(size=256) memory:f0300000-f030ffff memory:f0320000-f033ffff(prefetchable) Driver I was NOT running any proprietary drivers, just checked with "Hardware drivers". There is one for ATI that is suggested there, though I didn't need it so far. UPDATE: changing the driver to proprietary one (ATI/AMD FGLRX) didn't help. Tried and failed Resetting / running on power or battery / charging / getting rid of static electricity / warming up *doesn't help* This is NOT a blank-screen problem, at least it isn't following official Ubuntu black-screen diagnostics - I can see my screen, though barely. What I will try next: - check last updates I've made - IIRC I am running on nomodeset already, but will verify this Any ideas how to proceed best? What is most probable cause?

• How do I debug xorg/fglrx related system freezes on Ubuntu 12.10?

  - by racerror

  My brand new system is randomly freezing and I don't know how to debug the issue. System: AMD A10-5800k Asus F2A85-M motherboard Integrated Radeon HD 7660D 8gb Samsung ddr3 1600 Ubuntu 12.10 Gnome shell / Unity (issue exists in both) xorg.conf (relevant parts): Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:0:1:0" Option "TexturedVideoSync" "on" Option "UseFastTLS" "2" EndSection Section "Screen" Identifier "aticonfig-Screen[0]-0" Device "aticonfig-Device[0]-0" Monitor "Monitor0" DefaultDepth 24 Option "UseEDID" "False" Option "ExactModeTimingsDVI" "True" Option "NoBandWidthTest" "true" Option "ModeValidation" "AllowNon60hzmodesDFPModes, NoEDIDDFPMaxSizeCheck, NoVertRefreshCheck, NoHorizSyncCheck, NoDFPNativeResolutionCheck, NoMaxSizeCheck, NoMaxPClkCheck, NoEDIDModes" Option "UseEDIDDPI" "False" Option "UseEDIDFreqs" "0" Option "NoLogo" "True" Option "Coolbits" "1" Option "metamodes" "DFP-0: 2560x1440_60 +0+0" SubSection "Display" Depth 24 Modes "2560x1440" EndSubSection I ran memtest on my ram and it checks out fine. I have tried using the latest fglrx and fglrx-beta. I have loaded 3.6.x kernel. I do not see anything relevant in dmesg, kern.log, syslog, .xsession-errors or Xorg.log. I cannot ssh into the machine when frozen from another machine. I know that system resources not being stressed when the crashes happen. It seems that video and any gaming (very simple graphics games) contribute to the freezes most frequently. However, I have experienced the crash before when just using Chrome. I suspect the crashes are xorg/fglrx related, but I have no evidence to back that up. Where should I look? What should I grep for? What should I try next?

• What to learn after standard C++?

  - by Luca Cerone

  I switched to C++ a few months ago, learning its syntax, the main features of the STL and what you can usually find in a "learn C++" manual. Now I would like to go further. What would be your recommendations? I would like to know what to learn next (not only about the language, but also debugging, frameworks etc. etc.) I know probably the answer depends on the specific needs of each user, so here is a list of mine: Cross Platform development Developing GUI for my programs Develop extendible software, allowing the use of plugins Use of scientific libraries Interact with databases (mainly MySQL) Having server/client functionalities (I'd like users of my programs to interact through internet.. as you might have guessed I am not a programmer by training so I might have used the wrong terms.. if so I apologize for that). Of course I know it takes time, but I would like to have a good list of references and resources to start (both books and websites are ok). Thanks a lot for your help!

• Any examples of fair mmo games with quick completion

  - by Keith Player

  I'm looking for some example games for inspiration that allow from 10 to a large number of players at a time and can be completed in 10 to 30 minutes. I'm looking for something that would have extremely low bandwidth and not be dependent on chance or luck (i.e one player can't gain an unfair advantage because the computer put them in a better position). Realized on the way home that more clarifications might have been helpful. I'm looking to develop a pay-to-play competition that would allow a large number of players to compete in a relatively short period of time. One way would be to have an mmo that can be completed in 30 minutes, another way would be if you could have 10 person games that finish in under 5 minutes and then have the winners compete against each other until a winner is decided. I'm interested in any genre that would make for a fun/interesting game that doesn't depend on luck, so all players should have the same choice/availability of activities/resources and follow the same rules. Some possible games that could possibly be modified into what I want, would be bztanks (too easy to create a bot), diplomacy (takes too long), risk, some chess like game. I was just wondering if there are other game types to the ones I have been considering.

• How to join the World of Programming? [closed]

  - by litebread

  Name's Vlad and I am currently on my third year of Community College, studying Computer Science with emphasis on Programming in C++ and Networking. I have completed a few programming courses with general ease, but have not gained advanced understanding of programming through school. None of my friends are serious programmers working in the industry. Being an active lurker on many programming websites, and in general tech oriented sites I have noticed how little I know about the industry, the lingo and terminology. (I have no clue how Git hub works, but I generally understand what its for). So I am looking for help as to where I should look for information on the programming world and the industry in which I a very interested. By that I mean, what sites I should utilize to gain information on programming practices, introduction to advanced C++ and resources that simply introduce a 20some programming noob. I like programming, but I haven't dug my hands deep into it yet, I want to start to do so before I transfer to a University. All in all, where do I find information on becoming an actual programmer (Information that lays out a path). Thank you for reading. Have a great day!

• Structure of a .NET Assembly

  - by Om Talsania

  Assembly is the smallest unit of deployment in .NET Framework.When you compile your C# code, it will get converted into a managed module. A managed module is a standard EXE or DLL. This managed module will have the IL (Microsoft Intermediate Language) code and the metadata. Apart from this it will also have header information.The following table describes parts of a managed module.PartDescriptionPE HeaderPE32 Header for 32-bit PE32+ Header for 64-bit This is a standard Windows PE header which indicates the type of the file, i.e. whether it is an EXE or a DLL. It also contains the timestamp of the file creation date and time. It also contains some other fields which might be needed for an unmanaged PE (Portable Executable), but not important for a managed one. For managed PE, the next header i.e. CLR header is more importantCLR HeaderContains the version of the CLR required, some flags, token of the entry point method (Main), size and location of the metadata, resources, strong name, etc.MetadataThere can be many metadata tables. They can be categorized into 2 major categories.1. Tables that describe the types and members defined in your code2. Tables that describe the types and members referenced by your codeIL CodeMSIL representation of the C# code. At runtime, the CLR converts it into native instructions
