  • Trouble subnetting...

    - by ???
    I have to learn how to subnet by hand for a test. And I'm having real problems doing it. I keep getting stuck. Here's an example: 138.248.184.17/18 - IP 255.255.192.0 - Subnet Mask 192 = 1100 0000 in binary And I know 184 in the IP address is the "octet of interest". OK I get that far...and then I'm lost. I know I need to set the network bits of 192(I think?) to all 0 for the network ID and then to all 1 for the broadcast ID. Problem is how do I know which part of 11000000 is network and which part is host?

  • What benefits does a game design degree have for a hobby game programmer?

    - by sm4
    I am interested in studying game design, not because I want a job in the games industry, but because I am interested in the subject itself. I read the following questions, but they mostly deal with the effects on your career in game industry. Should I consider a graduate degree in game development? Game Development Degree vs Computer Science Degree First I thought a game development degree could be beneficial. But from the websites of colleges that offer such degrees, I feel like its more about basic programming with examples from games. This college offers game design degrees, for example. My question is, can I benefit from such a degree when I already have a degree in Computer Science, I already know programming, I'm already developing a game and finally, I have this site to help me when I get stuck?

  • Direct DB to Web Server connection

    - by Joel Coel
    I have a database server sitting right underneath a virtual machine host server in the rack, and this vm host is primarily responsible for servers hosting a couple different web sites and app servers that all talk to databases on the other server. Right now both servers are connected to the same switch, and I'm pretty happy with the pathing. However, both servers also have an unused network port. I wondering about the potential benefits of using a short crossover or normal+auto mdix network cable to connect these two servers together directly. Is this a good idea, or would I be doing something that won't show much benefit and is just likely to trip up a future admin who's not looking for this? The biggest weakness I can see right now is that this would likely require a code change for each vm app to point to the new IP of the database server on this private little network, and if I have a problem with the virtual machine host and have to spin up it's guests elsewhere while I fix it I'll have to change this back before things will work.

  • Best tools to build an auction website

    - by Daniel Loureiro
    Can I get your feedback on the best tools to build an auction website with the following features: The site takes a commission (like 5%) on each transaction Each user can assign a rating (like 4.5 stars) to his completed transaction, and comment on the seller's profile. Accept payments in paypal and credit card I've been looking into Joomla! and JomSocial but they haven't convinced me much so far. I have some programming experience in C, Python and Java. If no CMS tools are of use I'd appreaciate if you could tell the best route to take in programming to get the auction site done.

  • Admin mode on Procurve Switches

    - by stefan.at.wpf
    Not being a network expert, I spent some time configuring my network, until I found my mistake: On my HP ProCurve Switch 1810G, I thought that "Admin mode" means whether the administrative interface can be accessed from this port. Well, it means whether the port is enabled or not. Extract from the help function: Admin Mode - Select to enable the port-control administration state. Click to enable and have the port participate in the network.(Default : Enabled ) Well, of course I didn't read the help, because I didn't doubt it's for the adminsitrative interface and suspected an error somewhere else. Anyway, I am wondering if that is a commonly used term for enabling/disabling ports or if HP just wanted to make my life harder? I can't understand why this option isn't just called "Enable port"!? Here's a screenshot of how it looks in the web interface (yeah, shame on me for using a web interface)

  • Next in Concurrency

    - by Jatin
    For past year I have been working a lot on concurrency in Java and have build and worked on many concurrent packages. So in terms of development in the concurrent world, I am quite confident. Further I am very much interested to learn and understand more about concurrent programming. But I am unable to answer myself what next? What extra should I learn or work on to inherit more skills related to Multi-core processing. If there is any nice book (read and enjoyed 'concurrency in practice' and 'concurrent programming in java') or resource's related to Multi-core processing so that I can go to the next level?

  • Creating and Using a jQuery Plug-in in ASP.NET Web Forms

    - by bipinjoshi
    Developers often resort to code reuse techniques in their projects. As far as ASP.NET framework server side programming is concerned classes, class libraries, components, custom server controls and user controls are popular code reuse techniques. Modern ASP.NET web applications no longer restrict themselves only to server side programming. They also make use of client side scripting to render rich web forms. No wonder that Microsoft Visual Studio 2010 includes jQuery library by default as a part of newly created web site. If you are using jQuery for client side scripting then one way to reuse your client side code is to create a jQuery plug-in. Creating a plug-in allows you to bundle your reusable jQuery code in a neat way and then reuse it across web forms. In this article you will learn how to create a simple jQuery plug-in from scratch. You will also learn about certain guidelines that help you build professional jQuery plug-ins.http://www.bipinjoshi.net/articles/aae84a03-b4a8-477d-b087-5b7f42935220.aspx

  • Connecting both WAN and LAN ports to the same hub

    - by C. Lee
    For some reason I wish to connect the WAN port and the LAN port on a router to the same hub and make the hub is connected to both networks, the Internet and a private network. Below is a diagram of the network configuration I'd like to build. I tried this and it didn't work as expected. PC 1 has no problem, but PC 2 cannot connect to the Internet. When I ping 192.168.0.1 from PC 2, all packets are lost. It works well when PC 2 is connected directly to the router. What's the problem with the network configuration above?

  • Finding work as a college student

    - by lightburst
    I'm a 3rd year CS student. I'm currently really, really, bored and tired of cheap school programming(I go to a fairly respectable(albeit not top) university in my country, but, really, it's not MIT) so I've been thinking about getting a part-time dev job for a long while now. I'm not some hotshot programmer or anything, but "Add/Delete XYZ class objects to list" or "Do this web feature/pattern in PHP" does get old after a few semesters. I also only learned(heard?) of programming when I entered college, so the duration of me being in contact with any code is short. I can't really apply as an intern as I have not accumulated the necessary credits yet to do that so I was thinking of selling myself as a part-time dev. I still need to go to school, and don't want to subject myself to living two lives. Plus, I think I'd have better chances considering my lack of things to write on the resume. The only language I know at heart is C (I've written several pointer-oriented stuff on my freshman year, which is apparently pretty leet(for some reason), or so Joel says. That sort of boosted my morale a bit) but I've worked with several other languages only for the sake of course work such as C#/Java/PHP/ASM. My only user-worthy project was a recursive quicksort simulator I wrote for class using GTK+ that used a textbox to output the progress. I also have not taken the compiler theory class yet, or my thesis. All that being said, I wonder if any legitimate software company(big or small) would hire somebody like me considering all that. If there are companies that do accept anybody like me, would I be doing programming or maybe just be a tester or something? Would anybody hire me as a dev at all? I know I don't have much(not even a degree) but what I lack in experience, I compensate with interest? I am less interested in websites and 'management' software(no offense or anything. also, most of the places here ONLY have those), and more into 'process driven'(I'm not sure how to call it) and system software. I have my eyes on a startup that sells basically an extension of Google Drive, but I feel like I'm too 'risky' for them. Oh, I'm also 19 if that means anything. We're not K-12 so kids go to college earlier than in the US.

  • Switch user from locked screensaver?

    - by desert69
    I'm having the same problem as this, but the answer from there doesn't work for me. Neither in my iMac upgraded from Lion to Mountain Lion (currently at 10.8), nor from a Mac Mini with Lion Server (10.7.4). I have "Show fast user switching menu as" enabled at "Users & Groups" Login Options, but when I have to login from screensaver, there's no option to switch user. How can I enable such an option? EDIT: I think I forgot to mention that we believe (just guessing) that it has to do with network accounts. We use network accounts here, and have that issue. My boss says he could solve this issue at his house's Mac, which don't use network accounts. Does it make a difference?

  • Maker Faire 2012 Attendees build with Java Technology

    - by hinkmond
    Looks like Daniel Green, systems engineer from Oracle, and the panel of Java experts had a successful Java Technology booth at this year's Maker Faire 2012. See: Maker Faire 2012 adds Java Here's a quote: "We made a huge impact for Java and Oracle, creating positive perception, building brand awareness, and introducing fun and engaging ways for future technologists to learn Java programming," says Michelle Kovac, Oracle director, Java Marketing and Operations. Good stuff, considering all the future developers of exploding robots and fire-breathing dragon metal sculptures attend the Maker Faire. They can blow up stuff with Java technology just as effectively as other programming languages. Hinkmond

  • How to enable printer settings over Jetdirect on HP 4100N

    - by zsero
    I have a HP 4100N printer and I am using it over network. Previously I was able to access the printer settings over internet, but now the only thing visible is Device Info and Networking. I can connect to the web server and I can set all the network related settings, but that's not what I want. There should be a supplies, config, print info, etc. page, what are not visible now. Can you tell me what setting should I set to enable this printer config page on the webserver? The printer is a HP 4100N and the network card is J4169A (Jetdirect 610n).

  • How to configure bind9 to route to host's IP

    - by Greg
    I'm running apache and bind9 on the same server. I would like to set a master zone to route back to this very machine's IP address without explicitly specifying it. Is this possible? If I use 127.0.0.1 for the A record, then when another computer on the network does an nslookup for mydomain.local, bind of course just returns the loopback ip (127.0.0.1) -- not the IP of the server. Is there to way to tell it to just return the network IP address for the server itself, as defined in /etc/network/interfaces?

  • Looking Under the Hood of ...

    - by rickramsey
    copyright 2012 Rob Lang Fair is fair. Our last post featured a conversation with the beautiful and talented Eva Mendez, so today we're featuring something for those of you who prefer the other gender of our fair species. This dude has quite the hardware challenge ahead of him. He hasn't begun to find out what's really under that hood. Life is much easier for you and me, thanks to Jeff Wright and Suzanne Zorn. They wrote a wicked cool article about Oracle VM Server for SPARC. Here's a little bit about it... Looking Under the Hood of Networking in Oracle VM Server for x86 Oracle VM Server for SPARC lets you create logical networks out of physical Ethernet ports, bonded ports, VLAN segments, virtual MAC addresses (VNICs), and network channels. You can then assign channels (or "roles") to each logical network so that it handles the type of traffic you want it to. Greg King explains how you go about doing this, and how Oracle VM Server for SPARC implements the network infrastructure you configured. He also describes how the VM interacts with paravirtualized guest operating systems, hardware virtualized operating systems, and VLANs. Finally, he provides an example that shows you how it all looks from the VM Manager view, the logical view, and the command line view of Oracle VM Server for x86. More Resources for Oracle VM Server for x86 If you liked Greg and Suzanne's paper, you can ...

  • MAAS/JuJu Clarifications

    - by ectoskeleton
    I really love the concept of MAAS underlying an OpenStack implementation, but there are a few questions about MAAS that I am not entirely clear on. Should all hosts be set to network boot at all times or after they have been registered and allocated as a service, should they boot to disk? After juju bootstrap is executed, I turn on the machine that has been allocated (note WoL isn't working, I suspect it's being blocked on the network), the machine boot's up and then juju status executes correct, agent running and all that good stuff. If I 'reboot' the machine (testing power failure/problem whatever), juju status comes back but the agent-state is no longer in running state, and so far I have to destroy the environment and restart. In all cases I have never been able to deploy any services to any of the other nodes. I deploy the service with juju, note which node it was assigned, and then start the system. The system just boots up into a basic node. If I SSH to it I have to enter password, so it's not setting up the ssh key or anything. This is on Ubuntu 12.04.1 LTS systems and HP GL360G7 hosts. The MAAS management server is running as a VM but all on the same network. At this point I am not sure if I am doing something wrong or if there is a problem somewhere else. Is the idea that anytime a host is rebooted it should be rebuilt from the ground up, or is something else going on behind the scene to tell it to boot the local image. If the latter, why doesn't the agent start on a system that has been successfully setup before (juju bootstrapped system)?

  • career advice for PhD scientist seeking to program?

    - by C SD
    I'm largely a self-taught programmer. In fact, I first started programming about half way through biophysics grad school, and even though I think I've done some pretty nice work, I've never worked as part of a 'serious' development team that had more than one or two other developers (and I wouldn't hesitate to call them equally inexperienced in software development as a profession). After finishing my PhD I applied to Google, on a lark, since I had some confidence in my abilities, if not necessarily my experience, and I was hoping to maybe slip in and absorb all the experience and talent I'd be surrounded with and become productive enough, quickly enough, that they wouldn't immediately regret their decision. I was excited to actually get invited to interview up at Mountain View (this was ~ mid 2008). Overall, my memory of the interview was very positive, but after close to a three month wait (is that normal?) they ended up turning me down. I wasn't too surprised or disappointed (aside from the uncomfortably long wait) given my unusual background and admitted lack of experience. I decided to continue as a postdoc, but focus on improving my skills rather than doing research. I've done about three years of that, and my honest assessment is that I've learned a ton more, but I really need more of a peer group to maintain or accelerate my growth. Google invited me to interview again about eight months ago, and the interview process went even better than the first time around (I thought), though they again declined to give me an offer. I have to admit this second rejection was much more discouraging. They had insisted I interview even after I mentioned to them that a move on my part was unlikely given that I had bought a house, gotten married, etc. since the first interview. I guess I was hoping they'd at least give me an offer that I could parlay into a more conventional, but still interesting, programming position close to home. So here I am, going on my third year out of grad school, a glorified postdoc and I'm starting to get pretty discouraged. Even though I could technically get 'back-on-track' for a career in science, I have been focusing the vast majority of this time on gaining programming experience rather than on research and publications. The problem is, whenever I look, most job listings have requirements that seem impossibly grandiose and I hesitate to apply. That, or the job/project seems incredibly dull. Ironically, applying to Google struck me as less intimidating. I suspect that either most people are just a lot less realistic than I am when it comes to assessing how long it will take for them to get up to speed, or they don't care; my fear is that I'm just woefully unqualified for any interesting, well paying work. IE: I'm confident I could switch fully back into C++ mode with a couple weeks work (I mostly use C,Python,C# daily) but I don't list myself as being 'proficient' in C++ on my CV, or applying for jobs that 'require' such knowledge. The few applications for which I did feel I was a legitimately good match have not elicited a response. I suspect the following things are potential problems with my application/CV and I would like feedback on: I don't have a CS degree. My BS was in biochemistry and molecular biology, my PhD in biophysics. I took a undergrad and grad level CS course at UCSD and completely killed them, but I don't know how to translate that to my CV effectively. I have a PhD, but it's not in CS... I've been debating if I should remove it from my CV, and wether or not it would then be misleading to list at least some of those years as some kind of 'programming' job (in many respects it was). I think there are sometimes strong stigmas associated with 'self-taught' programmers. I am certainly one of those. I even recognize that some of those stigmas hold a hint of truth, but I really do want to be an asset to a team. How do I communicate that even though I have been largely self-directing for ~8 years I can still take marching orders when needed? Do I just say so outright? Should I just become a lot less scrupulous about the whole process? anecdote: I have a friend who applied for positions where he completely fudged his qualifications to get past the first culling. He was much more honest and forthcoming about his actual qualifications when contacted and he still managed to get invited to a couple of interviews and even got some offers. His balls are larger than mine though.

  • What Is StreamInsight? A Primer for Non-Programmers

    - by Roman Schindlauer
    Are you trying to figure out whether StreamInsight might be something you could use, but you’re having trouble sifting through all the programming jargon that’s used to describe it? StreamInsight is, ultimately, a set of programming tools, and at some point it takes a programmer to implement a StreamInsight solution. But it really should be possible to get a handle on what StreamInsight is all about even if you’re not a programmer yourself. A new article published in the TechNet Wiki may be able to help: StreamInsight for Non-Programmers. It gives an overview of the technology, but it leaves out the C# references and relates StreamInsight to more familiar SQL databases and queries. Check it out. When you’re done there and are ready to dig a little deeper, take a look at Get Started with StreamInsight 2.1. That article should help you navigate through the StreamInsight official documentation and other resources. And, as always, you can post questions or comments here or on the TechNet Wiki. Regards, The StreamInsight Team

  • What can programmers learn from the construction industry?

    - by Renesis
    When talking with colleagues about software design and development principles, I've noticed one of the most common sources for analogies is the construction industry. We build software and we consider the design and structure to be the architecture. One of the best ways to learn (or teach) are through analyzing analogies - what other analogies can be drawn from construction? (whether already in common use in software or not). Please provide a description, or your personal experience, regarding how the programming concept is similar to the construction concept. [Credit to Programming concepts taken from the arts and humanities for the idea]

  • How to execute files on LAN drives in a Windows Domain

    - by matnagel
    We have a very small LAN here, but some peolpe here think we need Active Directory, though nobody knows how to maintain it. I am not in the position to change this. How can I get full access (on Linux it would be "execute" rights) also for files on network drives (the files are just on another machine next room) My account is in the group Administrators on a windows 2003 server Domain Controller. I cannot open simple MS Access 2000 Databases or CHM Files from network drives in the lan How to do that? Some policy setting? I want to change that once. It is useless. We have no distinction between local or network files here. I would have to copy everything to a local drive and then do what I want.

  • Add 802.11n to existing 802.11g environment

    - by Andrew Robinson
    I have a small home network that is currently running 802.11g. Two computers that are capable of 802.11n and two devices (a BlackBerry and a Skype phone) that are limited to 802.11g. I have a few neighbors running 802.11g but their signals are very weak. How big an impact will the two G devices have on N speeds? Will they pull the whole network back down to G? These two devices are hardly ever used where as the other N devices are heavily used. If I add an N router to the network (instead of replacing the G) and set my existing G router to use channel 1 with 20MHz bandwidth and then set the N router to use 6 & 11 for 40MHz will I eliminate the overlap and allow for full speed on both networks?

  • Bridge 2 routers

    - by Nathan Adams
    I have 2 Linksys WRT54GL routers flashed with DD-WRT. On each I have a different ISP, and thus a different private network. I would like to be able to talk to either network regardless of what network I am on. Example: ISP1 - Router1 - Client ISP2 - Router2 - Client What I would like to do is something like: ISP1 - Router1 - Client              ^              |              v ISP2 - Router2 - Client This would be ideally because then I don't need to introduce another device in the mix, unless I have to. But I guess the first question is - is this even possible?
