  • Secure login for a game that is open source

    - by David Park
    I am making a game which i will be open sourcing. Its a simple arcade like game but requires a network connection because it is meant to be played with other people. The thing i am worrying about is how would i be sure that the client is the one that i put out for the end user to play with? Kind of a like of sv_pure for Team Fortress 2. I was thinking of different ways to combat this such as the server requesting the client's version or even it's md5 hash but people with simple java knowledge could just force a method to always return what the server wants.

  • Has RFC2324 been implemented?

    - by anthony-arnold
    I know RFC2324 was an April Fools joke. However, it seems pretty well thought out, and after reading it I figured it wouldn't be out of the question to design an automated coffee machine that used this extension to HTTP. We programmers love to reference this RFC when arguing web standards ("418 I'm a Teapot lolz!") but the joke's kind of on us. Ubiquitous computing research assumes that network-connected coffee machines are probably going to be quite common in the future, along with Internet-connected fruit and just about everything else. Has anyone actually implemented a coffee machine that is controlled via HTCPCP? Not necessarily commercial, but hacked together in a garage, maybe? I'm not talking about just a web server that responds to HTCPCP requests; I mean a real coffee machine that actually makes coffee. I haven't seen an example of that.

  • Cant get internet connection at all on Ubuntu 13.04

    - by James Ellis
    I installed Ubuntu 13.04 alongside my Windows Vista, at the start of installation it doesn't connect to the internet to download updates during installation, also during installation towards the end it removes a lot of stuff that i couldn't catch the details of at the time, it won't find my internet connection even though windows does, i tried using the ethernet cable but it wouldn't pick that up either. So i clicked in Ubuntu... System, network-Browse Internet, then Windows Internet and it said "failed to retrieve share list from server:no such file or directory" how can i get Ubuntu to find my internet???

  • Ideas for reducing storage needs and/or costs (lots of images)

    - by James P.
    Hi, I'm the webmaster for a small social network and have noticed that images uploaded by users are taking a big portion of the capacity available. These are mostly JPEGs. What solutions could I apply to reduce storage needs? Is there a way to reduce the size of images without affecting quality too much? Is there a service out there that could be used to store static files at a cheaper price (< 1GB/0.04 eurocents)? Edit: Updated the question.

  • Moodle Inconsistencies, Flowplayer, or Server?

    - by dglickler
    We are trying to decide if an issue we're having with Moodle and our videos is a flowplayer issue, a video issue, or a network issue. Any input is welcome. We've had videos in our Moodle (version 1.9, we're working on an upgrade on a different server) up for weeks, or even months. After that time, some of them have suddenly just stopped working. When they don't work, they just don't load. The videos work when we first upload them. With flowplayer, we don't get errors, just a blank screen. We have re-uploaded our videos several times when this has happened, but we really would like to know what's causing it so that we can prevent it. There are also no keyframe issues with the video. We are currently trying to find answers through various searches, but have not had any luck. I will continue to post more info as I come across it...but if there's anyone who knows or has ideas, it's welcome.

  • How did Ubuntu know my WPA Key?

    - by nebukadnezzar
    I've recently moved my /home to another computer (keeping all configuration files), with a fresh installation of Ubuntu 10.10. After Installation I've installed wicd and ndiswrapper, to get my Internet Connection up and running. However, after changing /etc/network/interfaces from auto lo iface lo inet loopback To auto wlan0 iface wlan0 inet dhcp and running sudo /etc/init.d/networking restart to get wlan0 set up, wicd just suddenly connected... to my modem. Without supplying any information about the modem whatsoever. Of course wicd creates a local directory at ~/.wicd/, but that directory is empty, and the temporary global configuration at /var/lib/wicd/configurations/ didn't exist due to fresh installation of ubuntu. So what's the deal? Where did wicd get the ESSID and the WPA Key? There hasn't been any activity in this question, but it's still open (and even worth some rep)!

  • Where Facebook Stands Heading Into 2013

    - by Mike Stiles
    In our last blog, we looked at how Twitter is positioned heading into 2013. Now it’s time to take a similar look at Facebook. 2012, for a time at least, seemed to be the era of Facebook-bashing. Between a far-from-smooth IPO, subsequent stock price declines, and anxiety over privacy, the top social network became a target for comedians, politicians, business journalists, and of course those who were prone to Facebook-bash even in the best of times. But amidst the “this is the end of Facebook” headlines, the company kept experimenting, kept testing, kept innovating, and pressing forward, committed as always to the user experience, while concurrently addressing monetization with greater urgency. Facebook enters 2013 with over 1 billion users around the world. Usage grew 41% in Brazil, Russia, Japan, South Korea and India in 2012. In the Middle East and North Africa, an average 21 new signups happen per minute. Engagement and time spent on the site would impress the harshest of critics. Facebook, while not bulletproof, has become such an integrated daily force in users’ lives, it’s getting hard to imagine any future mass rejection. You want to see a company recognizing weaknesses and shoring them up. Mobile was a weakness in 2012 as Facebook was one of many caught by surprise at the speed of user migration to mobile. But new mobile interfaces, better mobile ads, speed upgrades, standalone Messenger and Pages mobile apps, and the big dollar acquisition of Instagram, were a few indicators Facebook won’t play catch-up any more than it has to. As a user, the cool thing about Facebook is, it knows you. The uncool thing about Facebook is, it knows you. The company’s walking a delicate line between the public’s competing desires for customized experiences and privacy. While the company’s working to make privacy options clearer and easier, Facebook’s Paul Adams says data aggregation can move from acting on what a user is engaging with at the moment to a more holistic view of what they’re likely to want at any given time. To help learn about you, there’s Open Graph. Embedded through diverse partnerships, the idea is to surface what you’re doing and what you care about, and help you discover things via your friends’ activities. Facebook’s Director of Engineering, Mike Vernal, says building mobile social apps connected to Facebook in such ways is the next wave of big innovation. Expect to see that fostered in 2013. The Facebook site experience is always evolving. Some users like that about Facebook, others can’t wait to complain about it…on Facebook. The Facebook focal point, the News Feed, is not sacred and is seeing plenty of experimentation with the insertion of modules. From upcoming concerts, events, suggested Pages you might like, to aggregated “most shared” content from social reader apps, plenty could start popping up between those pictures of what your friends had for lunch.  As for which friends’ lunches you see, that’s a function of the mythic EdgeRank…which is also tinkered with. When Facebook changed it in September, Page admins saw reach go down and the high anxiety set in quickly. Engagement, however, held steady. The adjustment was about relevancy over reach. (And oh yeah, reach was something that could be charged for). Facebook wants users to see what they’re most likely to like, based on past usage and interactions. Adding to the “cream must rise to the top” philosophy, they’re now even trying out ordering post comments based on the engagement the comments get. Boy, it’s getting competitive out there for a social engager. Facebook has to make $$$. To do that, they must offer attractive vehicles to marketers. There are a myriad of ad units. But a key Facebook marketing concept is the Sponsored Story. It’s key because it encourages content that’s good, relevant, and performs well organically. If it is, marketing dollars can amplify it and extend its reach. Brands can expect the rollout of a search product and an ad network. That’s a big deal. It takes, as Open Graph does, the power of Facebook’s user data and carries it beyond the Facebook environment into the digital world at large. No one could target like Facebook can, and some analysts think it could double their roughly $5 billion revenue stream. As every potential revenue nook and cranny is explored, there are the users themselves. In addition to Gifts, Facebook thinks users might pay a few bucks to promote their own posts so more of their friends will see them. There’s also word classifieds could be purchased in News Feeds, though they won’t be called classifieds. And that’s where Facebook stands; a wildly popular destination, a part of our culture, with ever increasing functionalities, the biggest of big data, revenue strategies that appeal to marketers without souring the user experience, new challenges as a now public company, ongoing privacy concerns, and innovations that carry Facebook far beyond its own borders. Anyone care to write a “this is the end of Facebook” headline? @mikestilesPhoto via stock.schng

  • Help identifying device and driver for 0bda:1724

    - by user104547
    I've got a new Lenovo Ideapad Yoga 13. The onboard lan/bluetooth device is identified in Linux as 0bda:1724 (via lsusb). No network peripherals are reported from lspci. From the interwebs, the vendor:product above looks to be RT2573, however, in Windows, the device is identified as RTL8723A. Unfortunately, I have followed both roads, trying rt2500usb, rt2x00usb, and rtl8723e. I have emailed Realtek asking them for help but so far my email has fallen on deaf ears. I've posted the output of lspci -nn -v and lsusb -v to: http://pastebin.com/dqvTSVjF Any help at all would be appreciated. Thank you, Ryan

  • How do I get a Netgear WNDA3100V2 working?

    - by Michal
    I have Ubuntu 11.10 on my desktop. A month ago I bought Linksys AE1000 adapter,I did not check that it's not working on Ubuntu and because I've lost receipt I'm stuck with it. Last week I bought Netgear adapter and this time I did check and it meant to be plug an play but it was not. I have checked many forums and managed to install software, system does sees adapter but it's not connecting to network. I have found that it may not like WPA so I have created my own password-letters and digits,no spaces-still nothing.I don't understand why. This is my next attempt with Linux and I'm not with IT background so it takes time and research before I can resolve something but I really want to learn. I so wish to learn on Ubuntu.One day, I've checked Fedora16 and my old Linksys AE1000 worked without any instalations.

  • How to mount NAS folders via direct wired connection?

    - by Pavel Vlasov
    There are two machines connected to each other via network cable. One is notebook Ubuntu 12.04. Another is NAS Western Digital with a Debian. The NAS has some files shared via samba. I am not sure how it is called but under Windows these files are accessible via path \mybooklive\public. I know there is NFS - probably it is preferable over samba... So, how to get my files accessible from Ubuntu when a cable is plugged?

  • Enforce VPN connection to access the Internet

    - by ch0wn
    I'm using a VPN when I'm online at an unencrypted wifi. Unfortunately, at my university the connection is quite unstable and at every reconnect the VPN connection is terminated and I manually need to reconnect to it using the NetworkManager, which obviously only works if I notice the reconnect. I enabled the option to automatically connect to the VPN in the NM options, but it seems to have no effect. Is there a way to enforce an active VPN connection before any other application can access the network connection so I can be sure not to send private data over unencrypted connections? Cheers, Pascal

  • Slow Wireless Reconnect After Suspend - Broadcom 4312 with STA drivers

    - by nrhine1
    I am using 10.10 with STA drivers, I reinstalled ubuntu because the b43 drivers were giving me a huge hassle along with some weird kernel issues. My wireless speed is fine, everything works well, except upon restart of computer and after taking the computer out of suspend. It takes about 30-45 seconds for the wireless to reconnect, and I think it is a driver issue (I clicked on the network manager at the top and for about 30 seconds there are no wireless networks listed.) I tried this advice already: http://lilserenity.wordpress.com/2007/10/31/fix-ubuntu-dropping-wireless-on-suspendhibernate-resume/ which basically says to change this: STOP_SERVICES="" to STOP_SERVICES="networking" in the file /etc/default/acpi-support This did not help anything. Something to note is that the issue does not occur when I am logging back in after already logging in once and logging out.

  • Replace Broadcom "wl" driver with "b43"

    - by Laszlo Boros
    I'm using Ubuntu 10.04.4 LTS, and in my laptop there is a Broadcom BCM4312 wlan card. lspci output: 04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) Subsystem: Broadcom Corporation Device 04b5 Flags: bus master, fast devsel, latency 0, IRQ 18 Memory at f4500000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [58] Vendor Specific Information Capabilities: [e8] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [d0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [13c] Virtual Channel Capabilities: [160] Device Serial Number 81-ac-1d-ff-ff-12-54-92 Capabilities: [16c] Power Budgeting Kernel driver in use: wl Kernel modules: wl, ssb So as you can see, the current (and default) driver is wl - installed with jockey. But I have another Ubuntu based distribution on my laptop (BackTrack linux), which is also 10.04, but it has the b43 driver installed and the overall performance is MUCH better. So I would like to install it on this OS too, but even google didn't help me. So my question is how to install the latest b43 driver on my Ubuntu?

  • Installing gdm on headless Server Edition

    - by Andrew Koester
    I have Ubuntu Server running on a headless box, which is right now, almost entirely doing only software RAID and feels a little underused. I'd like to get into using Ubuntu as a desktop a little more. What do I need to do (install/etc.) to get Gnome while keeping the box itself headless? I'm not sure which packages to install or which steps to take. I figure I'll just use X over the network (Xming or the like) but something like NX might work.

  • Turn your laptop into a wireless Access Point with Windows 7!

    - by David Nudelman
    Windows 7 offers a very cool feature where you can connect multiple devices to any wired and wireless network connection (hotel, cable, 3G, UMTS, EDGE, WIFI, RJ45, Ethernet, etc.) by turning your own laptop into a wireless AP (Access Point) to relay those devices not directly connected to the internet. For this just enter these two commands to an elevated (right click on CMD.EXE, run as administrator): netsh wlan set hostednetwork mode=allow ssid=YOURFRIENDLYSSID key=SOMEPASSWORD netsh wlan start hostednetwork At this point, if Internet Connection Sharing (ICS) is setup, anyone can connect to your SoftAP (if they know the PWD of course) and the traffic will be sent through whatever adapter you want. You can actually bridge it across an entirely different adapter... or the same on a different Wifi LAN. A GUI to set this up can be downloaded for free here: http://www.connectify.me/
