• What undergraduate course to choose for a mature programmer returning to study

  - by Dve

  I have been developing applications (mostly web-based) for almost 10 years now and have learnt pretty much everything I know through experience (and the internet!). I wouldn't call myself an advanced programmer, but I am quite proficient in several languages (C#, Javascript, Ruby, HTML/CSS etc) and spend a quite a bit of time working on personal projects and reading countless books & articles. I am looking to emigrate to Canada, hopefully Vancouver (im from the UK) and one way would be on a student visa, if I was going to be studying for a minimum of 2 years. Having never been to university or achieved anything higher than A-Levels I am quite tempted by this path. The thought of learning is more exciting to me now than it was 10 years ago! What would be people recommend as a good undergraduate course to take that would complement this career path? Would Math be beneficial, if so which area of Math? TL;DR What undergraduate course/area of study would complement 10 years of (mostly web-based) programming experience?

• Network connection delay after installing indicator-network

  - by Adrian

  Ok, so here's the thing,I installed wingpanel in UBUNTU 10.10, i removed the gnome-panels (yes, both). In the wingpanel itself there's no NETWORK indicator, so i google it and in some forums, some guy wrote that you have to install "indicator-network". I did it, and it solved the network indicator in the wingpanel, BUT now everytime i turn on my computer, the connection takes like 2 minutes or more to connect, when before installing this thing it did it immediately. How can i solve this? any help?

• nm-applet gone?

  nm-applet seems to have disappeared from my system. I am running 12.10.

• Educational, well-written FOSS projects to read, study or discuss

  - by Godot

  Before you say it: yes, this "question" has been asked other times. However, I could not fine many of such questions and not that easily, and those I found had similar results. What I'm trying to say that there are no comprehensive lists of well written Open Source projects, so I decided to set some requirements for the entries (one or possibly more): Idiomatic use of the language in which they are written The project should be lightweight. Not as in "a few kbs", as in "clean" and possibly following the UNIX philosophy, making an efficient use of resources and performing its duty and nothing more. No code bloat, most importantly. Projects like Firefox and GNOME wouldn't qualify, for example. Minimal reliance on external, non-standard libraries, with exceptions for some common FOSS libraries (curses, Xlib, OpenGL and possibly "usual suspects" like gtk+, webkit and Boost). Reliance on well-written libraries is welcome. No reliance on proprietary software - for obvious reasons (programs that rely on XNA, DirectX, Cocoa and similar, for example). Well-documented code is welcome. Include link to web interfaces to their repositories if possible. Here are some sample projects that often pop up in these threads: Operating Systems Plan 9 from Bell Labs: More or less, the official "sequel" to UNIX. Written in C by the same people who invented C! NetBSD: The most portable BSD implementation, written in C and also a good example of portable and organized code. Network and Databases Sqlite: Extremely lightweight and extremely efficient, one of the best pieces of C software I've seen. Count the lines yourself! Lighttpd: A small but pretty reliable web server written in C. Programming languages and VMs Lua: extremely lightweight multi-paradigm programming language. Written in C. Tiny C Compiler: Really tiny C compiler. Not really comparable to GCC or Clang but does its job. PyPy: A Python implementation written in Python. Pharo: OK, I admit it, I'm not really a Smalltalk expert but Pharo is a fork of Squeak and looked rather interesting. Stackless Python - An implementation of Python that doesn't rely on the C call stack - written in C (with some parts in Python) Games and 3D: Angband: One of the most accessible roguelike codebases around here, written in C. Ogre3D: Cross-platform 3D engine. Gets bloated if you don't skip the platform-specific implementation code, otherwise is a pretty solid example of good C++ OO. Simon Tatham's Portable Puzzle Collection: Title says it all. Other - dwm: Lightweight window manager. Written in C. Emulation and Reverse Engineering - Bochs: x86 emulator, written in C++ and tiny enough. - MAME: If you want to see C at one of its lowest levels, MAME is for you. May not be as clean as the other projects but it can teach you A LOT. Before you ask: I didn't mention Linux because it has become quite bloated in the last few years, Linus has also confirmed it. Nonetheless, it'd be a great educational read the same, even if for other reasons. Same for GCC. Feel free to edit or wikify my post. I hope you won't lock my question, I'm only trying to organize a little community effort for the good of all those people who want to enhance their coding skills.

• Neural Network settings for fast training

  - by danpalmer

  I am creating a tool for predicting the time and cost of software projects based on past data. The tool uses a neural network to do this and so far, the results are promising, but I think I can do a lot more optimisation just by changing the properties of the network. There don't seem to be any rules or even many best-practices when it comes to these settings so if anyone with experience could help me I would greatly appreciate it. The input data is made up of a series of integers that could go up as high as the user wants to go, but most will be under 100,000 I would have thought. Some will be as low as 1. They are details like number of people on a project and the cost of a project, as well as details about database entities and use cases. There are 10 inputs in total and 2 outputs (the time and cost). I am using Resilient Propagation to train the network. Currently it has: 10 input nodes, 1 hidden layer with 5 nodes and 2 output nodes. I am training to get under a 5% error rate. The algorithm must run on a webserver so I have put in a measure to stop training when it looks like it isn't going anywhere. This is set to 10,000 training iterations. Currently, when I try to train it with some data that is a bit varied, but well within the limits of what we expect users to put into it, it takes a long time to train, hitting the 10,000 iteration limit over and over again. This is the first time I have used a neural network and I don't really know what to expect. If you could give me some hints on what sort of settings I should be using for the network and for the iteration limit I would greatly appreciate it. Thank you!

• "Hostile" network in the company - please comment on a security setup

  - by TomTom

  I have a little specific problem here that I want (need) to solve in a satisfactory way. My company has multiple (IPv4) networks that are controlled by our router sitting in the middle. Typical smaller shop setup. There is now one additional network that has an IP Range OUTSIDE of our control, connected to the internet with another router OUTSIDE of our control. Call it a project network that is part of another companies network and combined via VPN they set up. This means: They control the router that is used for this network and They can reconfigure things so that they can access the machines in this network. The network is physically split on our end through some VLAN capable switches as it covers three locations. At one end there is the router the other company controls. I Need / want to give the machines used in this network access to my company network. In fact, it may be good to make them part of my active directory domain. The people working on those machines are part of my company. BUT - I need to do so without compromising the security of my company network from outside influence. Any sort of router integration using the externally controlled router is out by this idea So, my idea is this: We accept the IPv4 address space and network topology in this network is not under our control. We seek alternatives to integrate those machines into our company network. The 2 concepts I came up with are: Use some sort of VPN - have the machines log into VPN. Thanks to them using modern windows, this could be transparent DirectAccess. This essentially treats the other IP space not different than any restaurant network a laptop of the company goes in. Alternatively - establish IPv6 routing to this ethernet segment. But - and this is a trick - block all IPv6 packets in the switch before they hit the third party controlled router, so that even IF they turn on IPv6 on that thing (not used now, but they could do it) they would get not a single packet. The switch can nicely do that by pulling all IPv6 traffic coming to that port into a separate VLAN (based on ethernet protocol type). Anyone sees a problem with using he switch to isolate the outer from IPv6? Any security hole? It is sad we have to treat this network as hostile - would be a lot easier - but the support personnel there is of "known dubious quality" and the legal side is clear - we can not fulfill our obligations when we integrate them into our company while they are under a jurisdiction we don't have a say in.

• How to send raw data over a network?

  - by youllknow

  Hi everyone! I've same data stored in a byte-array. The data contains a IPv4 packet (which contains a udp-packet). I want to send these array raw over the network using C# (preferred) or C++. I don't want to use C#'s udp-client for example. Does anyone know how to perform this? Sorry for my bad English and thanks for your help in advance!!!

• Network / Internet diagnostic tool to locate an error?

  - by Jesper

  Hi, I’m facing some difficulties with the Internet / network at my work and I have trouble locating the precise error and when and how it occurs. The problem is that the client machines in the house sporadic is disconnected to the Internet. I’m some what new so I haven’t that much inside in the network and apparently neither has my predecessor. What I am requesting and hoping you guys knows about is, if there exist some kind of network monitor tool I can install and run and it will periodically check the network, the Internet connection etc. and record to logs. Then, if there suddenly arises a problem some time of the day in some part of the network or the Internet connection, I can check it perhaps the next day. I’ve just downloaded and installed Microsoft Network Monitor 3.3 application and hopeful it can give me some answers on where the instability is located but I still would like a tool to make different checks and test in some time interval. Do anyone know about such a program or another kind of performance / diagnostic tool / method I can use? Sincere Jesper

• Make Network Manager use bridge for PPPoE instead of only working on ethernet?

  - by Azendale

  My ISP uses PPPoE on their DSL connections. I use Network Manager to connect to this using a bridged modem connected to eth0. Often, I want to test networking things, so a set myself up a KVM machine with a tap interface. I can then connect these interfaces to to virtual 'switches' by adding them to bridges. (I work for my ISP). Sometimes, I want to test cases where the PPPoE is connected more than once. For this, I would like to be able to add eth0 to my 'switch' (a bridge) so the VMs can have a 'bridged modem' connection to the internet. But I would like to still be able to run the PPPoE for my computer at the same time. Which means that I need to get network-manager to run PPPoE over the bridge (or eth0). The problem is that it considers eth0 (and the bridge) 'not managed' by network manager, so it refuses to use it. So, how can I have network manager dial PPPoE over a bridge?

• Bridging: Loosing WLAN network connection with 4addr on option - Why?

  - by WitchCraft

  Question: For use with my Xen VM, I need to create a virtual network interface (vif) that is bridged to wlan0. If in /etc/network/interfaces I add auto xenbr0 iface xenbr0 inet dhcp And then later do brctl addif xenbr0 wlan0 I get this error message. can't add wlan0 to bridge xenbr0: Operation not supported I found out that Linux won't let you bridge a wireless interface in managed mode at all unless you enable the 4addr option (needed to recompile iw): iw dev wlan0 set 4addr on Afterwards brctl addif xenbr0 wlan0 works, and brctl show shows xenbr0 as bridged to wlan0. Unfortunately, as soon as I execute iw dev wlan0 set 4addr on my entire network connection is gone (no connection). As soon as then I execute iw dev wlan0 set 4addr off I reconnect and it works again. If I re-execute 4addr on, it breaks again, if I execute 4addr off, it works again. Unfortunately, I can't just turn 4addr on, activate the bridge and then turn it back off (error: device not ready). Does anybody know why I loose my connection ?

• Wireless Network Issue, Disconnecting Randomly From Network

  - by Surfer513

  I'm having an odd problem with my wireless network. Here is the background information: Server (Windows Server 2008) 1 to 10 end user machines connecting to the network Layer 3 Access Point (Asus WL-330 gE) connected to ethernet of Server and all machines connect to the network via the AP The end user machines get a connection to the server with no problems initially. But then connections are randomly lost throughout the day to the server/network. The wireless NICs of the machines still see the wireless network but are unable to connect to it. Then after some time the connection is regained automatically. I initially thought there was a problem with this particular AP, but then I took the same make/model AP out of storage and still ran into the problem. Any ideas what could be causing this??? Very confusing that the wireless nics on the end user machines can still see the network but not connect, and that the connections are randomly lost/gained. Thanks in advance!

• Configure a wireless network that accepts any WPA2-PSK network key

  - by Michel

  I recently bought a UART WiFi module ( this one ) and configured it with right SSID but wrong password( and I don't know what it is ). The problem is that I can't reset this module to its manufacture settings and I can't connect to this module via serial port to configure it with some wire or cable. But I'm sure that my module is trying to connect my access point but with wrong network key ( because in logs of my access point I can see my module that trying to connect but it can't ) So, I wonder to know is there any way to create or configure a network (using some access point or something else) based on WPA2 Personal security that accepts any WPA2-PSK passwords ? Or is there any other solution for this problem ? If no, is there anyway to see what password this module using to connect to that network ? ( If yes, then I can change password of my network to that password and access to this module's admin panel ) I tried create an open network ( without any security key ) but my module just searches for WPA2 based networks ( I think ).

• Not able to access other machines on network

  - by TheVillageIdiot

  Hi I'm running Windows 7 Enterprise (32bit) on my laptop. For some time I'm not able to access other machines using \\192.168.xxx.xxx. I've installed VM Ware player on my machine few days back but I don't remember if it happened just after that or there is some other reason behind it. EDIT:- I've disabled VMWare Bridge Protocol but still no effect. Please help me. PS:- I've used both wireless and wired networks. Network sharing is enabled and I can ping other machines but cannot access network shares. I get following message: \\xxx.xxx.xxx.xxx You might not have permission to use this network resource. Contact the administrator of this server to find out if you have acess permissions. The request is not supported. EDIT (2):- Network Discovery, File and Printer Sharing, Folder sharing are all on.

• Why is it bad to map network drives in Windows?

  - by Beeblebrox

  There has been some spirited discussion within our IT department about mapping network drives. In particular, it has been said that mapping network drives is A Bad Thing and that adding DFS paths or network shares to your (Windows Explorer/Libraries) Favourites is a far better solution. Why is this the case? Personally I find the convenience of z:\folder to be better than \\server\path\folder', particularly with cmd line and scripting (of course I'm not talking about hard-coded links, naturally!). I have tried searching for pros and cons of mapped network drives, but I haven't seen anything other than 'should the network go down, the drive will be unavailable'. But this is a limitation of any network-accessed storage... I have also been told that mapped network drives poll the network when the network resource is unavailable, however I haven't found more information on this. Wouldn't this still be an issue with other network access mechanisms (that is, mapped Favourites) whenever Windows tries to enumerate the file system (for example, when a file/folder picker dialog is opened)? -- Do network drives poll the network any more than a Windows Explorer library/favourite?

• Keep Xubuntu Network Manager from overwriting resolv.conf

  - by leeand00

  How do I keep Xubuntu 11.10 from overwriting resolv.conf everytime I reboot my machine? Everytime I reboot, I get an overwritten resolv.conf that has the words # Generated by Network Manager and no nameservers specified. I ran the following to get rid of Network Manager, but it's still replacing my resolv.conf when I restart the machine. sudo apt-get --purge remove network-manager sudo apt-get --purge remove network-manager-gnome sudo apt-get --purge remove network-manager-pptp sudo apt-get --purge remove network-manager-pptp-gnome

• SQL SERVER – Vacation, Travel and Study – A New Concept

  - by pinaldave

  Quite often when developers go to training sessions they either find it very boring because of study or great because they treat it as a vacation. There should be a perfect balance between study and extra activities. Studying is Boring Studying is very hard. Nobody likes to study, very few people are going to list “studying” as one of their favorite hobbies.  Already my young daughter knows she doesn’t want to study, and I don’t want to either.  If you read my blog regularly you know that I am always saying that we need to be students for life.  However, all philosophy aside, if you are put in a room with an instructor to study for eight hours a day, you are going to feel bored, uncomfortable, and unhappy.  I was a trainer myself, and I understand that all-day study sessions are no fun – even for the trainer.  I always tried to be entertaining, but even eight hours of jokes and laughter is tiresome.  Eight hours at a comedy club would be boring after a little while – and if we can’t even enjoy fun stuff for eight hours straight, how can we expect to study for eight hours straight? Studying for Career or Certification Even those who have advanced degrees and went to college for years, or even decades, find studying hard.  There is a difference between studying for a career and studying for a certification.  At least to get a degree there is a variety of subjects, with labs, exams, and practice problems to make things more interesting.  You can also choose your major and what you want to spend your time studying.  For certification you do not have this luxury.  You have to learn and memorize specific parts, and there is no option to change your major if you don’t like it.  Your option is to gain your certification, or fail.  Many people will find that last option unacceptable. Studying at Vacation We have established: eight hours of uninterrupted study is boring.  That is why I am so excited about what my very good friend is doing with Koenig Solutions.  His whole goal was to make classes that are intensive but not in a traditional format.  He adds in aspects of the vacation.  It is true that you will study and sit with instructors for six or eight hours a day, but in the mornings and evenings you can go out and see the sights in exotic locations.  He has chosen the locations for his training courses for their proximity to tourist attractions like the Himalayas, the Taj Mahal, and Goa, India’s most popular resort town.  Every location has access to great experiences like river rafting, safari tours, or meditation.  There are five locations to choose from: Dehli, Dehradun, Shimla (close to the Himalayas), Goa Beach, and Dubai.  After a day of classes and hours of sight-seeing, you will be more than ready to return to campus tired and ready to study.  This is the kind of study I can do! My friend’s point is that studying and fun can still go hand-in-hand.  How many times have we heard a professor say this?  But this time it is true.  There is great fun in learning in exotic locations.  If you want to travel in India and are interested in also taking the opportunity to learn something, let Koenig Solutions know.

• Why are two indicator-network versions being worked on?

  - by Daniel Rodrigues

  Some months ago, on the road to Ubuntu Maverick, a new system indicator, network (with connman as a backend), started to be developed. The plan was to get it into UNE and release it with no notifcation area. Unfortunately it didn't make it into the final version. However, continued efforts are still being made to improve it, and I'm getting regular updates. From a blueprint from the last UDS, I read that the plan was to ship no notification area and only indicators. For that, it was defined that nm-applet (backend: NetworkManager) should be ported to the appindicator library. Today I discovered that those efforts are going on and a initial version is available for testing, available from Matt Trudel PPA (Natty only). So, my questions is, to whoever has the necessary info: wouldn't it be easier to join efforts and concentrate the work in just one version (probably NetworkManager backend, as that's the official plan), instead of breaking those efforts apart and hampering both testing and developing? Both indicators are being developed by Canonical engineers, and that really doesn't make much sense. So, any Canonical engineer willing to clarify this?

• 12.04 wired network doesn't work RTL8111/8168B

  - by laket

  its a fresh 12.04 install 64bits. wifi works fine, wired stays off with cable connected and network-manager shows as if cable is disconnected. Turning off networking lights up my network-cards leds, turning networking on shuts off the leds and no communication is possible. I already tried, turning off the network-manager (sudo service network-manager stop) and setting up my eth0 manually, as soon as I switch off the network-manager my leds light up, but after setting up manually eth0 (sudo ifconfig eth0 10.2.10.114 netmask 255.255.0.0 up) the leds turn off again. I am still dual booting with 10.04 where I have no issues at all, leaving the cable connected all time to my notebook and a switch.

• How do I ban a wifi network in Network Manager?

  - by Chris Conway

  My wifi connection drops sometimes and, for some reason, Network Manager attempts to connect to my neighbor's network, which requires a password that I don't know. The network in question is not listed in the "Edit Connections..." dialog and I can find no reference to it in any configuration file, but still the password dialog pops up every time my main connection drops. Is there a way to blacklist a wireless network so that the Network Manager will never attempt to connect to it? Or, equivalently, how can I remove the configuration data that causes the Network Manager to attempt to connect to this particular network?

• Adding network share as the system account breaks Win7 backup to network

  - by ChrisBenn

  (On Win7 Ultimate x64 SP1) So I've been using Win7 backup to \192.168.0.100\Backup\main-desktop\ for awhile without issue. Yesterday I tried to setup crashplan to synchronize my dropbox folder and a network share. I then found out that crashplan, as it runs under the system account, can't see my user mapped drives. So I created a startup script net use O: \192.168.0.100\Documents /USER:192.168.0.100\username password and set it to run, on startup, after the network interface is up, as the system account. (the username & password are the same for the net use script above, the locally logged in user, and the explicit username/password entered in windows backup). I woke up this morning to find error flags from the windows backup and get "Network location cannot be used" (0x800704B3). If I disable the startup task & reboot then windows backup works fine. I'm not sure why having a mapped drive for another user is killing windows backup (same server, different folder). I can work around the issue by using another program to synchronize the two folders, but I'm completely in the dark as to why this happens (and it's 100% repeatable). Uninstalling the crashplan client doesn't change anything - it's the net use run under the system account that breaks win7 backup (to a network location).

• How should I study programming languages?

  - by gcc

  I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter).

• Which network performance management software do you use?

  - by Jamie Keeling

  Hello, I am looking at the various options available for network performance management software, some of the solutions I've found so far are: Proprietary: HP - ProCurve Universal: SolarWinds - Orion Open Source: OpenNMS I am trying to discover the benefits of each package over the other and reasons as to why you would go for one (Such as size of the network, overall cost etc..). I'm curious as to which ones other people use and why? Each customer has their own needs and requirements and it would be great to hear some of yours. Thank you for your time.
