• What shall I include in a 10 week web technologies course?

  - by Iain

  In September I will be teaching a university module on web technologies. This session will be available to 1st year (freshman) students who don't necessarily have any programming knowledge or know how the web works. In the 2nd semester I will be teaching Flash, which is my specialism, so I know exactly what I am going to teach, but in the 1st semester I will be teaching them web standards technologies - HTML, CSS, JS, jQuery, PHP and MySQL. Where I need advice is how to proportion the emphasis for each part, and which parts of each technology to cover. Another real issue I'm struggling with is how much of the bad old ways should I teach them? Do they need to know about bold as well as strong, etc. UPDATE: based, on your feedback I will only be teaching the latest version of everything - CSS3, HTML5 etc. I'm not sure exactly how long the semester will be but I'm guessing about 10-12 weeks. Each session is a 2 hour lab. Obviously there's only so much I can cover in that time and it will be up to the students to go a research this stuff properly on W3 schools etc. My ideas so far were: Lesson 0 - Course intro and overview of the current tech landscape. What is out there, what will we be learning, what won't we. What is a web server, URL etc. Looking at different example websites and discussing how they work. Lesson 1 - HTML basics (head, body, title, img, table, a, lists, h1, strong etc) Lesson 2 - CSS for styling and layout - fonts, webfonts, float etc Lesson 3 - Intro to programming JS (variables, loops, conditionals, functions) Lesson 4 - more JS programming fundamentals, DOM manipulation Lesson 5 - jQuery - making things fly about and look cool Lesson 6 - XML and Ajax Lesson 7 - PHP basics - syntax, server-side principles Lesson 8 - PHP and MySQL - forms, logins, saving user info Lesson 9 - don't know Lesson 10 - don't know Please let me know if you think this is the right order, what have I missed, how to use any spare sessions etc. Thanks :) UPDATE BASED ON RESPONSES: Thanks for all your responses - some great stuff. To be absolutely clear, this is not a computer science course, it is a practical module on a creative technology course. The emphasis definitely has to be on making cool things work rather than understanding how the backbone of the internet works. That can come later, if the students are interested. At the end of the module I would like the students to be able to produce a web page or pages that does something cool, using some or all of the technologies I cover. Many of these topics are of course far beyond the scope of a 2 hour session, however I do not have the option of reducing the syllabus, I will just have to explain what the technology does and encourage the student to research it in their own time.

• How do I remove/uninstall a corporate VPN?

  - by Metro Smurf

  I have a corporate VPN installed on one of my Windows XP systems that I'd like to completely uninstall. There are no programs listed in the add/remove programs dialog matching the corporate VPN name or similar. I can find the VPN being launched from here: C:\Documents and Settings\All Users\Application Data\Microsoft\Network\Connections\Cm\<Company Name> I can see the VPN connection under network connections: Name Type Device Name Connection Manager ------------------- Connection to <Company Name> Connection Manger WAM Miniport (PPTP) Do I just need to delete the connection from Network Connections? And delete the directory? Or?

• Serializing Data Structures in C

  - by src

  I've recently read three separate books on algorithms and data structures, tcp/ip socket programming, and programming with memory. The book about memory briefly discussed the topic of serializing data structures for the purposes of storing it to disk, or sending it across a network. I can't help but wonder why the the other two books didn't discuss serialization at all. After an unsuccessful web/book search I'm left wondering where I can find a good book/paper/tutorial on serializing data structures in C? Where or how did you learn it?

• Solution for lightweight LAN peer discovering?

  - by DevilWithin

  I built a library for purely cross-platform programming. My games made with it run fine in Android , Pc, Linux, Mac etc. The networking capabilities are provided by ENET library, therefore all communication between my apps is not TCP or UDP compatible, but only in the custom protocol, even tough its based on the UDP ultimately. I don't think its possible to do what i want with ENET, thats why I ask here for help! Lets say I have the same game running in my Android phone, my laptop and my pc. They are all in the same wifi network, and therefore in a LAN, whether its Wifi hotspot(?) or the household router. I need each of those 3 peers to discover the other two in the network. This is meant only to find the IP of alive apps in the LAN network, to be able to host multiplayer games between them. I can only think of one effective way to do this, UDP broadcast, wait responses, but if that is the solution, i need something small, since its the only purpose of the implementation. Other way could be to try to connect to all IPs in the LAN address subrange, but I don't think the OS would be with me on this one :p Sorry for the long question!

• Host a subdomain from an IIS7 server on another server

  - by brennanmur

  I am running a network with two server, one running SBS 2008 which hosts a majority of the network services (DNS, DHCP, Exchange, IIS, DC, AD...), including the primary webpage at mydomain.com. The other server is a linux box running an apache web server. I'm trying to set the apache server to host the site site2.mydomain.com. I have changed the DNS settings on the first server so that site2.mydomain.com can be accessed from the internal network, but I cannot access site2.mydomain.com from the internet. I have tried using server farms and application request routing cache, as described on this page, http://forums.iis.net/t/1156458.aspx, but I still can't access site2.mydomain.com from the internet. I don't have much experience with web servers, I usually just administer local networks, so I'm not sure if I'm going about this the right way. Any help or suggestions would be much appreciated.

• How should I organise classes for a space simulator?

  - by Peteyslatts

  I have pretty much taught myself everything I know about programming, so while I know how to teach myself (books, internet and reading API's), I'm finding that there hasn't been a whole lot in the way of good programming. I am finishing up learning the basics of XNA and I want to create a space simulator to test my knowledge. This isn't a full scale simulator, but just something that covers everything I learned. It's also going to be modular so I can build on it, after I get the basics down. One of the early features I want to implement is AI. And I want to take this into account as I'm designing my classes so I can minimize rewriting code. So my question: How should I design ship classes so that both the player and AI can use them? The only idea I have so far is: Create a ship class that contains stats, models, textures, collision data etc. The player and AI would then have the data for position, rotation, health, etc and would base their status off of the ship stats.

• SSL Certificate for local web server

  - by Firefly

  Is it at all possible to create a self-signed certificate for use on multiple machines on a local network which would stop the browser complaining it is not a trusted site? We have a product which is basically a computer running lighttpd to serve a web interface for configuring the computer (sort of how a router has a web interface). There can also be many of these machines running on the same network with dynamic IP's. What I basically want to do is enable SSL for extra security but I don't want people who are on the local network to be given a browser warning about the certificate not being trusted. Is this at all possible?

• Another Exchange 2003 to Exchange 2010 mail flow issue

  - by Ryan Roussel

  During a migration recently, we came across another internal mail routing issue.  The symptoms were identical to my previous post about Exchange internal mail routing.  Mail was flowing from 2010 to 2003, from 2010 to the internet, but not from 2003 to 2010.   I went through the normal check list looking at permissions, DNS, and the routing group connectors.  I verified that both servers listed in the routing group connectors were the routing master in their respective routing groups through the 2003 ESM.  I also verified that inheritable permissions were enabled for the Exchange 2003 server object in the schema.  No luck with either.   For my previous post about this issue in which inheritable permissions were the culprit: Exchange 2010, Exchange 2003 Mail Flow issue   And for Routing Group issues: Exchange 2007 Routing Group Connector Mayhem   I finally enabled logging on the SMTP virtual server on Exchange 2003 and the Default Receive Connector on 2010 and sent a few test e-mails where I found 2003 was having issues authenticating to 2010.  By default 2003 uses Exchange Server Authentication to communicate to 2010. The exact error was: 4.7.0 Temporary Authentication Failure which was found in the SMTP logs on the Exchange 2003 side   After scouring based on this error, I found the solution:   The Access this computer from the network user rights in the local computer policy on the Exchange 2010 server were changed from the default.  The network administrator had modified the Default Domain policy and changed this user right assignment to only list Domain Users.   The fix was to clear this setting in the Default Domain policy,  force gpupdate to refresh the group policy settings, then ensure the appropriate users and groups were listed.   This immediately fixed the problem and the Exchange 2003 server was able to route mail to the Exchange 2010 mailboxes.   The default user rights assignments for Access this computer from the network On Workstations and Servers: Administrators Backup Operators Power Users Users Everyone On Domain Controllers: Administrators Authenticated Users Everyone More can be found here: http://technet.microsoft.com/en-us/library/cc740196(WS.10).aspx

• Windows 7 PPTP VPN problem

  - by Marco Martins

  Hi, I'm currently using an win 7 as an network server at my home. I've created some shared folders wich can be accessed easily from any pc on my network (win and mac computers) recently I decided to turn on the win 7 pptp to access remotely to my server from anywhere. the problem is with that on, on my router my server ip change, acording to my ipconfig on the cmd my router gets the ip from a "PPP adapter RAS (dial in)". when that happens I cannot access to the shared files over the lan on my mac, but i can connect to the vpn but again can't access to my files. (i've tried connecting to the vpn from another network and it worked, even the file share) anyone can help me? thanks

• Two VPN (internet) connections rounting (win2003)

  - by tmp3128

  Here is my setup: - win2003 server (ISA installed) with 3 NICs:   1) internal network   2) ISP 1 (default) network (DHCP enabled)   3) ISP 2 (backup) network (DHCP enabled) - several "normal" PC within internal net - one "special" PC within internal net Both ISP 1 and ISP 2 provide access to internet and their resources thru their VPN connections. The goal is to enable all "normal" PCs to use internet from ISP_1's VPN connection and "special" should use only ISP_2's VPN connection. Futhermore all "normal" and "special" PCs should have access to several servers accesible only thru ISP_2's VPN connection. I have some thoughts how to achieve this but I want to be certain because everything should be configured as quickly as posible, avoiding significant downtime. windows-server-2003 isa routing vpn

• Learning the basics

  - by Kevin

  I am a Linux server administrator first and foremost... Having said that, I have been asked by a former high school teacher of mine to teach students a bit about programming. Like any Linux administrator, I know my fair share of Python and Bash. The problem is that I know NOTHING about the lower level stuff like "machine code" and compilation. The main purpose of this series is to teach programming, not computer science, so I don't need a graduate degree's level of knowledge for this, they will be learning Python first and foremost. However, I would like to learn enough to at least broach the subject with them, any ideas where I can learn that kind of stuff relatively quickly?

• What is Pseudocode?

  - by Jae

  I've seen a lot of mentions of Pseudocode lately, on this site and others. But I don't get it: What is Pseudocode? For example, the Wikipedia article below says "It uses the structural conventions of a programming language, but is intended for human reading rather than machine reading." Does this mean that it isn't actually used to make programs? Why is it used? How is it used? Is it considered a Programming Language? See the above Wikipedia quote. Is it commonly known/used? Anything else... I honestly don't know where to start with this. I have Googled it and I've seen the Wikipedia article on the topic, but I still don't fully understand what it is.

• What kind of position matches my skills, experience and interests? [closed]

  - by Ryan

  I work in a large firm and my current job covers a variety of different duties. Due to several factors I am seriously considering finding a new job (hours, pay-cut, limited career growth). I have worked for the company nearly 4 years and almost 2 years ago I transitioned into more of a business analyst role (previously I was working in a client facing role for our audit group). In this role I have overseen all aspects of the development of a large scale re-platforming of our firm's key tool in analyzing investment portfolios. I gathered requirements, wrote specs, designed the UI and functionality, worked closely with developers (onshore and offshore) to see to it the implementation was correct, managed schedules and was the lead tester. This is a large scale system used by thousands of people around the world. I've also written Excel macros, reports in SQL, given trainings, written technical manuals, interfaced with senior managers and partners, etc. I've been on a couple interviews sporadically, most of which were for positions aimed at higher management consulting type positions, dealing with strategy, overall process management, project management, etc. What really interests me is the technical stuff and overseeing a project from beginning to end (although I would rather not have to do so many of the tasks on my own). I genuinely like a lot of what I do, but the company culture and attitude towards overworking people combined with my recent pay-cut (my overtime was cut due to a promotion to a higher level) has lead me to want to seek work elsewhere. The problem is - what type of work could I realistically do? I feel like traditional business analysis is too much business and not enough tech stuff, and I've really taken a shine lately to beefing up my programming abilities and creating small programs to automate things around work. I also feel that because my actual years of experience as a business analyst (figure 1.5 years realistically) puts me at a junior level doing a lot of grunt requirements gathering, when the work that I have been doing with my current company is more in line with what a Program Manager does (depending on your definition I guess). So in reality, when I'm job hunting I get a bit perplexed because I feel like the traditional BA stuff wouldn't really suit me, and even if it did it's usually something along the lines of 5-10 years experience for the type of work that is similar to what I've done (and I've also found most BA jobs to be contract only which at the moment I'm not too keen on). Program Manager is something that interests me, but again I feel like the experience is lacking because that's a much more senior position. Am I in some kind of career no-man's land? Any idea what would best suit me given my experience and abilities, as well as my interests? I plan to keep learning programming on the side, but don't expect to get a job being a straight programmer given my relative inexperience with programming.

• Is wikipedia a valuable resource for studying data structures? (can we call it complete?)

  - by Amir Nasr

  Can I depend on wikipedia to learn data structures fully using the list of data structures http://en.wikipedia.org/wiki/List_of_data_structures and the links they refer to? The same question for algorithms http://en.wikipedia.org/wiki/List_of_algorithm_general_topics ?... What's after learning algorithms and data structures? Specializing in a certain field of algorithms such as computer graohics, memory management...etc? or what could be the plan for mastering programming after knowing the language syntax and the background about program design and programming logic? I asked about wikipedia because i would like to find a complete resource or are least a resource which would be enough for the field of data structures instead of searching for separate articles in different places in other words an alternative to books which may even be more complete.

• How do I set my router up to authenticate with my service provider?

  Currently I have this setup: D-Link DSL2640U connected to the phone line: VPI/VCI 0/40, Service Category UBR Without PCR Service pppoe_0_40_3 Interface nas_0_40 Protocol Bridging (LLC/SNAP-Bridging) 802.11q not enabled Bridge Service Enabled Computers have individual PPPoE connections (in Network and Sharing Centre - Set up a new connection or network - Connect to the Internet - Broadband (PPPoE) - Username and Password) How would I move these settings on each individual PC to the router so that all I need to do is connect to the wireless? I have been unsuccessful setting up anything other than Windows PCs on the network (I have tried Macs, iOS and Nokia SmartPhones too). Thanks for the responses in advance!

• What are the advantages of OSPF vs nexthop self with iBGP?

  - by Matt Hamilton

  Assuming I have a fairly small network internally, but I have 4 routers each connected out to a different network. The routers are all sat next to each other connected via a switch. Each router uses BGP to speak to the outside networks. There is an iBGP mesh for each router to exchange the routes internally it knows about from each external network. The usual setup is to use OSPF to distribute the connected routes, as the routes via iBGP will still have the next hop set to their original value. What is the advantage of using OSPF in this scenario versus simply using 'set nexthop self' on the routes?

• Applying for MS CS with an un-related Bachelor's Degree [closed]

  - by yeenow123

  I received a BA in Economics and went to work and started developing a passion for programming while on the job. This lead to learning more and more about computer science in general. I want to go for a Masters in Computer Science. I'm taking courses at the local college to get some of the undergrad CS courses out of the way (Data Structures etc.). However I'm not sure what to focus on for my application. Should I take the GRE for CS? A lot of college application procedures recommend it if you didn't go to undergrad for CS. Should I try to improve my GRE general test? I took it a month after college ended and got mediocre scores, so I could definitely study a bit harder and improve my scores. Anything else that's necessary? My current job is not exactly in a related field, but I do get to do some programming/coding.

• psloggedon timeout question.

  - by user60707

  Hi guys, I have a list of machine names from my network that I have put in a batchfile to run through the list and show me who is logged onto each. psloggedon \machineA psloggedon \machineB psloggedon \machineC psloggedon \machineD psloggedon \machineE psloggedon \machineF Psloggedon works fine, however when it hits a machine that isnt actually on the network, it hangs for a good 30 - 60 seconds before moving onto the next machine...I was just wondering if there was any way to speed this up so that if it hits a machine that isnt on the network, it moves onto the next machine in the list much quicker. I have read in other places that this could be possible by adding a ping -n loop into the command but im not sure how to get that to work? any ideas guys? Many thanks in advance. Jimmy

  I'm planning to Implement CDN(Content Delivery Network) of Amazon which is known as CloudFront in ASP.NET MVC3 with c#. I've googled about it but little bit confuse about few things mentions below. Is it compulsory that we have to uploads all static resources to CDN Network first and then we can use or Is it manageable by Amazon to crawl site static resources which is predefine folder or directory of sites? Is Amazon automatic update its copies when we anything change in static resources or every time we have to upload updated resources to CDN network.

• How do I access an Ubuntu VirtualBox guest at a static IP from an OS X host?

  - by David Siegel

  How does one configure an Ubuntu guest to use a static IP that's visible to an OS X host, and ensure that the static IP is independent of the host's network configuration? I previously used bridged networking for my guest, but I'm constantly moving my host between networks so the guest IP is always different. First, I tried setting the guest network configuration to NAT and forwarding host port 1022 to guest port 22, so I could at least ssh to a fixed address (localhost:1022): $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/Protocol" "TCP" $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/GuestPort" 22 $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/HostPort" 1022 Then, $ ssh localhost -p 1022 ssh: connect to host localhost port 1022: Connection refused But this didn't work (guest has no network access with NAT and OS X refused the connection, as you can see). I'd love a general solution that would let me communicate with my guest at a fixed IP.

• Clustering Strings on the basis of Common Substrings

  - by pk188

  I have around 10000+ strings and have to identify and group all the strings which looks similar(I base the similarity on the number of common words between any two give strings). The more number of common words, more similar the strings would be. For instance: How to make another layer from an existing layer Unable to edit data on the network drive Existing layers in the desktop Assistance with network drive In this case, the strings 1 and 3 are similar with common words Existing, Layer and 2 and 4 are similar with common words Network Drive(eliminating stop word) The steps I'm following are: Iterate through the data set Do a row by row comparison Find the common words between the strings Form a cluster where number of common words is greater than or equal to 2(eliminating stop words) If number of common words<2, put the string in a new cluster. Assign the rows either to the existing clusters or form a new one depending upon the common words Continue until all the strings are processed I am implementing the project in C#, and have got till step 3. However, I'm not sure how to proceed with the clustering. I have researched a lot about string clustering but could not find any solution that fits my problem. Your inputs would be highly appreciated.

• Windows VPN - NO internet access

  - by sharru

  I host a network of servers behind a Fortigate 200a firewall in the DC. I connect to those servers via a VPN connection. The problem is that when i connect to the VPN, I lose my internet connection on the local PC (windows 7). I would like to be connected to the VPN and still surf the web. i guess this means to only forward a range of ip to the VPN connection. I've read other answers on serverfault, talking about "un-check the 'Use default gateway on remote network' option in your Windows 7 PPTP network connection settings". When i do that , i get internet access but no access to the servers in the VPN. Any idea how to get both working? Should i change something on the fortigate 200a config? Do i need two networks cards? Is there a place in windows to define ip range for the vpn connection?

So I decided to build a bitTorrent client. I think I understand to some point how the protocol works. I have also downloaded the source code of deluge bittorrent client. I have access to python documentation too.

• Doing practice jobsearch/technical interviews?

  - by Beekguk

  I graduated college last year & I've never gone through the interview process - my current programming position evolved out of projects I did in school, but in a few months I'm making a clean break and moving across the country so I'm going to have to face a "grown-up" jobsearch. I'm kind of scared of technical interviews - I think I'm pretty good at my job and my hobby programming projects ... but what if it turns out I'm part of that group that thinks they're qualified, but really just cause despair at the state of education in the hearts of interviewers? So, I'm thinking of doing a "practice" job hunt in my current city to get an idea of what it's like and what kind of experience/expertise employers are really looking for. Is this a dick move ethically (applying to/interviewing for jobs I can't take)? If so, is there another good way to prepare for technical interviews, especially those little trick puzzle-type questions?
