• What is the best CPU I could get for my old setup?

  - by cmbrnt

  On my current not-so-good desktop computer, I'm currently running an Intel Core 2 Duo E6550-CPU, and I'm thinking of buying a newer one now that these must be cheap on E-bay and the like. Being a software guy, I'd be grateful for any help in identifying what CPUs that would fit my motherboard so I don't buy a processor which won't work with my computer. It might not be worth it however, since the SATA2-drive is currently what's bottlenecking my system, but I'm still curious about what could be done except for buying an SSD-drive. I'm providing screenshots of CPU-Z running, to help with the identification. My CPU- and motherboard info: http://i.imgur.com/YdO8x.png

• setting up synergy (multi-computer shared input devices) new to mac

  - by pedalpete

  I've just gotten a mac and the first thing I'm trying to do in setting it up for dev is to set-up synergy. I've run into countless issues, and am making progress, but that 'mac's just work' theory is getting tired really fast. I'd prefer running the mac as the server, as it's a desktop. why use my pc(laptop) as the server. So i downloaded synergy, and tried to edit the 'synergy.conf' file. First with textmate, then with apple script. Neither of these applications will open the file. Even after changing textmate to use plain text format and switching off a few other things to make it into a plain text editor. No good. Uh, isn't that what these script/text editors are for? Then I found SyneryKM which is a package to run synergy on osx. Took LOTS of fiddling, but I think I finally kinda got it figured out. I've got my pc & mac both running synergy. However, my pc will only connect to synergy using the ip address. No problem, however, my mac won't connect to itself as a synergy server using the IP address. If I use the ip address as a screen in the 'server configuration file', i get a 'Error: unknown screen name mymac'. I know this shouldn't be super complicated, and possibly not the place to find answers about synergy, but I couldn't find a better place, and there has been some talk of synergy here. Any chance somebody can help with this?

• Type of computer for a developer on the road

  - by nabucosound

  Hi developers: I am planning to be traveling through eurasia and asia (russia, china, korea, japan, south east asia...) for a while and, although there are plenty of marvelous things to see and to do, I must keep on working :(. I am a python developer, dedicated mainly to web projects. I use django, sqlite3, browsers, and ocassionaly (only if I have no choice) I install postgres, mysql, apache or any other servers commonly used in the internets. I do my coding on vim, use ssh to connect, lftp to transfer files, IRC, grep/ack... So I spend most of my time in the terminal shells. But I also use IM or Skype to communicate with my clients and peers, as well as some other software (that after all is not mandatory for my day-to-day work). I currently work with a Macbook Pro (3 years old now) and so far I am very happy with the performance. But I don't want to carry it if I am going to be "on transit" for long time, it is simply huge and heavy for what I am planning to load in my rather small backpack (while traveling, less is more, you know). So here I am reading all kind of opinions about netbooks, because at first sight this is the kind of computer I thought I had to choose. I am going to use Linux for it, Microsoft is not my cup of tea and Mac is not available for them, unless I were to buy a Macbook air, something that I won't do because if I am robbed or rain/dust/truck loaders break it I would burst in tears. I am concerned about wifi performance and connectivity, I am going to use one of those linux distros/tools to hack/test on "open" networks (if you know what I mean) in case I am not in a place with real free wifi access and I find myself in an emergency. CPU speed should be acceptable, but since I don't plan to run Photoshop or expensive IDEs, I guess most of the time I won't be overloading the machine. Apart from this, maybe (surely) I am missing other features to consider. With that said (sorry about the length) here it comes my question, raised from a deep ignorance regarding the wars betweeb betbooks vs notebooks (I assume tablet PCs are not for programming yet): If I buy a netbook will I have to throw it away after 1 month on the road and buy a notebook? Or will I be OK? Thanks! Hector Update I have received great feedback so far! I would like to insist on the fact that I will be traveling through many different countries and scenarios. I am sure that while in Japan I will be more than fine with anything related to technology, connectivity, etc. But consider that I will be, for example, on a train through Russia (transsiberian) and will cross Mongolia as well. I will stay in friends' places sometimes, but most of the time I will have to work from hostel rooms, trains, buses, beaches (hey this last one doesn't sound too bad hehe!). I think some of your answers guys seem to focus on the geek part but loose the point of this "on the road" fact. I am very aware and agree that netbooks suck compared to notebooks, but what I am trying to do here is to find a balance and discover your experiences with netbooks to see first hand if a netbook will be a fail in the mid-long term of the trip for my purposes. So I have resumed the main concepts expressed here on this small list, in no particular order: keyboard/touchpad feel: I use vim so no need of moving mouse pointers that much, unless I am browsing the web, but intensive use of keyboard screen real state: again, terminal work for most of the time battery life: I think something very important weight/size: also very important looks not worth stealing it, don't give a shit if it is lost/stolen/broken: this may depend on kind of person, your economy, etc. Also to prevent losing work, I will upload EVERYTHING to the cloud whenever I'll have a chance. wifi: don't want to discover my wifi is one of those that cannot deal with half the routers on this planet or has poor connectivity. Thanks again for your answers and comments!

• recommendation for good chassis (case) for first time PC builder

  - by studiohack

  I've been thinking about building my own machine for some time now, and whenever I look at the PC case market, it seems like cases are a dime-a-dozen. As a result, I'm wondering what cases Super Users would recommend in the areas of ease of use, cable management, cooling, etc...in other words, an all-around case for a first time PC builder. Thanks!

• Computer Networks UNISA - Chap 12 &ndash; Networking Security

  - by MarkPearl

  After reading this section you should be able to Identify security risks in LANs and WANs and design security policies that minimize risks Explain how physical security contributes to network security Discuss hardware and design based security techniques Understand methods of encryption such as SSL and IPSec, that can secure data in storage and in transit Describe how popular authentication protocols such as RADIUS< TACACS,Kerberos, PAP, CHAP, and MS-CHAP function Use network operating system techniques to provide basic security Understand wireless security protocols such as WEP, WPA and 802.11i Security Audits Before spending time and money on network security, examine your networks security risks – rate and prioritize risks. Different organizations have different levels of network security requirements. Security Risks Not all security breaches result from a manipulation of network technology – there are human factors that can play a role as well. The following categories are areas of considerations… Risks associated with People Risks associated with Transmission and Hardware Risks associated with Protocols and Software Risks associated with Internet Access An effective security policy A security policy identifies your security goals, risks, levels of authority, designated security coordinator and team members, responsibilities for each team member, and responsibilities for each employee. In addition it specifies how to address security breaches. It should not state exactly which hardware, software, architecture, or protocols will be used to ensure security, nor how hardware or software will be installed and configured. A security policy must address an organizations specific risks. to understand your risks, you should conduct a security audit that identifies vulnerabilities and rates both the severity of each threat and its likelihood of occurring. Security Policy Content Security policy content should… Policies for each category of security Explain to users what they can and cannot do and how these measures protect the networks security Should define what confidential means to the organization Response Policy A security policy should provide for a planned response in the event of a security breach. The response policy should identify the members of a response team, all of whom should clearly understand the the security policy, risks, and measures in place. Some of the roles concerned could include… Dispatcher – the person on call who first notices the breach Manager – the person who coordinates the resources necessary to solve the problem Technical Support Specialist – the person who focuses on solving the problem Public relations specialist – the person who acts as the official spokesperson for the organization Physical Security An important element in network security is restricting physical access to its components. There are various techniques for this including locking doors, security people at access points etc. You should identify the following… Which rooms contain critical systems or data and must be secured Through what means might intruders gain access to these rooms How and to what extent are authorized personnel granted access to these rooms Are authentication methods such as ID cards easy to forge etc. Security in Network Design The optimal way to prevent external security breaches from affecting you LAN is not to connect your LAN to the outside world at all. The next best protection is to restrict access at every point where your LAN connects to the rest of the world. Router Access List – can be used to filter or decline access to a portion of a network for certain devices. Intrusion Detection and Prevention While denying someone access to a section of the network is good, it is better to be able to detect when an attempt has been made and notify security personnel. This can be done using IDS (intrusion detection system) software. One drawback of IDS software is it can detect false positives – i.e. an authorized person who has forgotten his password attempts to logon. Firewalls A firewall is a specialized device, or a computer installed with specialized software, that selectively filters or blocks traffic between networks. A firewall typically involves a combination of hardware and software and may reside between two interconnected private networks. The simplest form of a firewall is a packet filtering firewall, which is a router that examines the header of every packet of data it receives to determine whether that type of packet is authorized to continue to its destination or not. Firewalls can block traffic in and out of a LAN. NOS (Network Operating System) Security Regardless of the operating system, generally every network administrator can implement basic security by restricting what users are authorized to do on a network. Some of the restrictions include things related to Logons – place, time of day, total time logged in, etc Passwords – length, characters used, etc Encryption Encryption is the use of an algorithm to scramble data into a format that can be read only by reversing the algorithm. The purpose of encryption is to keep information private. Many forms of encryption exist and new ways of cracking encryption are continually being invented. The following are some categories of encryption… Key Encryption PGP (Pretty Good Privacy) SSL (Secure Sockets Layer) SSH (Secure Shell) SCP (Secure CoPy) SFTP (Secure File Transfer Protocol) IPSec (Internet Protocol Security) For a detailed explanation on each section refer to pages 596 to 604 of textbook Authentication Protocols Authentication protocols are the rules that computers follow to accomplish authentication. Several types exist and the following are some of the common authentication protocols… RADIUS and TACACS PAP (Password Authentication Protocol) CHAP and MS-CHAP EAP (Extensible Authentication Protocol) 802.1x (EAPoL) Kerberos Wireless Network Security Wireless transmissions are particularly susceptible to eavesdropping. The following are two wireless network security protocols WEP WPA

• Why is Software Engineering not the typical major for future software developers?

  - by FarmBoy

  While most agree that a certain level of Computer Science is essential to being a good programmer, it seems to me that the principles of good software development is even more important, though not as fundamental. Just like mechanical engineers take physics classes, but far more engineering classes, I would expect, now that software is over a half century old, that software development would begin to dominate the undergraduate curriculum. But I don't see much evidence of this. Is there a reason that Software Engineering hasn't taken hold as an academic discipline?

• super() in Python 2.x without args

  - by Slava Vishnyakov

  Trying to convert super(B, self).method() into a simple nice bubble() call. Did it, see below! Is it possible to get reference to class B in this example? class A(object): pass class B(A): def test(self): test2() class C(B): pass import inspect def test2(): frame = inspect.currentframe().f_back cls = frame.[?something here?] # cls here should == B (class) c = C() c.test() Basically, C is child of B, B is child of A. Then we create c of type C. Then the call to c.test() actually calls B.test() (via inheritance), which calls to test2(). test2() can get the parent frame frame; code reference to method via frame.f_code; self via frame.f_locals['self']; but type(frame.f_locals['self']) is C (of course), but not B, where method is defined. Any way to get B?

• super-space-optimized code

  - by Will

  There are key self-contained algorithms - particularly cryptography-related such as AES, RSA, SHA1 etc - which you can find many implementations of for free on the internet. Some are written to be nice and portable clean C. Some are written to be fast - often with macros, and explicit unrolling. As far as I can tell, none are trying to be especially super-small - so I'm resigned to writing my own - explicitly AES128 decryption and SHA1 for ARM THUMB2. What patterns and tricks can I use to do so? Are there compilers/tools that can roll-up code?

• KBXXXXX does not apply, or is blocked by another condition on your computer

  - by Jason Banico

  I have uninstalled VS 2010 and many other apps that I don't use anymore, and reinstalled it after. I have also reinstalled VS 2010 SP1. I'm now down to 3 updates, of which I am getting the error: "KB2522890 does not apply, or is blocked by another condition on your computer." I have already disabled my antivirus and Windows Defender. It also happens to the other updates: VS10SP1-KB2529927-v2-x86 VS10SP1-KB2548139-x86 VS10SP1-KB2549864-x86 It is possible that Microsoft Update is right that they do not apply, as I only installed VS 2010 C# and Web development. Why is it recommending that I install them then?

• Unlimited and multi-computer online storage solutions with automatic backup

  - by JRL

  As the title says, what are the existing online storage solutions that provide: unlimited storage automatic backup and allow for an unlimited number of computers (use not tied to a single computer)? There are several existing questions on this site related to online storage solutions, but none that is specifically targeted to what I want, so I thought I'd ask the question. This wikipedia article lists some of them, are there others? How do they compare in terms of price, feature set and ease of use? Update: Kinda disappointed no one has any answers to this so far. JungleDisk looks promising, anyone have experience with it? Update 2: To answer the comments, what I'm looking for definitely DOES exist. These solutions all seem to fit the bill: BackMii CrashPlan DataPreserve Humyo JungleDisk KeepVault SpiderOak And some of them are quite cheap (CrashPlan is $100 a year). For unlimited space and computers, I'd say that's pretty good. Does anyone have experience with CrashPlan or any other of the above solutions?

• powerpoint make computer shut down on dell optiplex 760

  - by yael

  hello, At my office we upgraded group of computers to windows 7 + office 2010, few of us have problem that when we work on powerpoint - once in a while the computer suddenly shut down (with out any message). Some of us - has no such problems. We checked and fount that the people who experience problems - use Dell Optiplex 760 PC, and everyone that have no problems use other models. We also found out that the processors of the 760's are not the same - some are Intel E7400 and one is Intel E8400, so I suspect that maybe the mother board is the problem Does any one no this problem? Does any one have an idea about it? Any help will be appreciated. Thanks, Yael

• Computer starts, POSTs normal, no video

  - by Annath

  So, I recently tried to start up an old computer of mine. It would not power on, so I replaced the PSU. When I powered it on, all the fans spun up and the POST beeps indicated a normal startup. The problem was there was no video output. Every couple of minutes, I hear the post code again. I think it is restarting after POST, but without video I have no idea why. Does anyone have an idea as to why this is happening, and how to fix it? EDIT: The video card is a PCI-e card. There is no integrated graphics on the motherboard. If I remove the video card, the POST indicates a missing card. When I put it back, it goes back to normal, so I know that it recognizes that the card exists.

• Computer shutsdowns when trying to boot

  - by Zexanima

  I have an IBM ThinkCentre, and I was talking to someone on Skype when it suddenly just shutoff. When I rebooted it asked me to start windows normally or in safe mode, but as soon I choose an option (Any of them) it shuts back down. So I thought it was a problem with windows and tired booting from a Hirens disk, but same thing. I've been using this computer without problems for over a year know. Any idea's for me to try? Unfortunatly I don't have any powersupplies or extra RAM to switch out to try anything like that. EDIT I left it off for a while and it's booting to windows now. I would still like to know what might have been causing it to do that if you have any ideas.

• Connecting desktop computer to the internet through laptop wifi

  - by Josh

  Due to some home network complications I have had to move my router to a seperate part of the house, therefore the wired network I had set up can no longer work. Before I find the time to go out and buy a Wifi adapter for my desktop PC, I have a laptop that uses a built in Wifi card to connect to my router and this can connect to the internet, and I was wondering if I could somehow access the internet on my desktop PC via my laptop. I'm hoping for a not-so-complex solution as this will only be set up for a few days, but it is quite vital that my desktop computer gets internet access. Does anyone have experience in this sort of thing and can help me out? Thanks.

• moving dynamic disk from Windows to another Windows computer when original Windows is not available

  - by Andrei

  How do I mount dynamic disk on new system without access to the old OS ? I need to move Dynamic data disk from old Windows XP (Pro, SP3) system, where disk crashed, to new Windows system without having access to the old OS. On new system, Dynamic disk shows as "Dynamic - Foreign". Microfoft has instructions for moving Dynamic Disk [1]. But Microsoft assumes having access to the old system. But I do not have acess to the old system. I am struck with "Dynamic - Foreign" static of the disk on new system.

• Black Screen when Computer Boots

  - by BlueRaja

  I'm having a serious problem with my computer; I think I've narrowed it down to the motherboard, but I'd like a second opinion before I spend the money. Before I moved into my new apartment, my desktop was working fine; now, it just won't work. It will turn on, the fans will spin up, lights come on... but nothing appears on the screen. No POST, nothing. I've tried: A different monitor (both are VGA) A different video-card (both are DVI, PCIe) Three different, known-good VGA-DVI adapters The onboard video port (VGA) Reseating the memory, and trying only one stick Different, known-good wall-outlets Unplugging the HDD and CD-drive from both the motherboard and PSU Replacing the PSU Has anyone had this happen before? Perhaps it's a known problem with this motherboard? Any advice!? Here are my specs: A13G+ V3.0 motherboard 2 2-gig 800mhz DDR2 600-watt PSU two older Geforce video cards
