  • Use BGInfo to Build a Database of System Information of Your Network Computers

    - by Sysadmin Geek
    One of the more popular tools of the Sysinternals suite among system administrators is BGInfo which tacks real-time system information to your desktop wallpaper when you first login. For obvious reasons, having information such as system memory, available hard drive space and system up time (among others) right in front of you is very convenient when you are managing several systems. A little known feature about this handy utility is the ability to have system information automatically saved to a SQL database or some other data file. With a few minutes of setup work you can easily configure BGInfo to record system information of all your network computers in a centralized storage location. You can then use this data to monitor or report on these systems however you see fit. BGInfo Setup If you are familiar with BGInfo, you can skip this section. However, if you have never used this tool, it takes just a few minutes to setup in order to capture the data you are looking for. When you first open BGInfo, a timer will be counting down in the upper right corner. Click the countdown button to keep the interface up so we can edit the settings. Now edit the information you want to capture from the available fields on the right. Since all the output will be redirected to a central location, don’t worry about configuring the layout or formatting. Configuring the Storage Database BGInfo supports the ability to store information in several database formats: SQL Server Database, Access Database, Excel and Text File. To configure this option, open File > Database. Using a Text File The simplest, and perhaps most practical, option is to store the BGInfo data in a comma separated text file. This format allows for the file to be opened in Excel or imported into a database. To use a text file or any other file system type (Excel or MS Access), simply provide the UNC to the respective file. The account running the task to write to this file will need read/write access to both the share and NTFS file permissions. When using a text file, the only option is to have BGInfo create a new entry each time the capture process is run which will add a new line to the respective CSV text file. Using a SQL Database If you prefer to have the data dropped straight into a SQL Server database, BGInfo support this as well. This requires a bit of additional configuration, but overall it is very easy. The first step is to create a database where the information will be stored. Additionally, you will want to create a user account to fill data into this table (and this table only). For your convenience, this script creates a new database and user account (run this as Administrator on your SQL Server machine): @SET Server=%ComputerName%.@SET Database=BGInfo@SET UserName=BGInfo@SET Password=passwordSQLCMD -S “%Server%” -E -Q “Create Database [%Database%]“SQLCMD -S “%Server%” -E -Q “Create Login [%UserName%] With Password=N’%Password%’, DEFAULT_DATABASE=[%Database%], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF”SQLCMD -S “%Server%” -E -d “%Database%” -Q “Create User [%UserName%] For Login [%UserName%]“SQLCMD -S “%Server%” -E -d “%Database%” -Q “EXEC sp_addrolemember N’db_owner’, N’%UserName%’” Note the SQL user account must have ‘db_owner’ permissions on the database in order for BGInfo to work correctly. This is why you should have a SQL user account specifically for this database. Next, configure BGInfo to connect to this database by clicking on the SQL button. Fill out the connection properties according to your database settings. Select the option of whether or not to only have one entry per computer or keep a history of each system. The data will then be dropped directly into a table named “BGInfoTable” in the respective database.   Configure User Desktop Options While the primary function of BGInfo is to alter the user’s desktop by adding system info as part of the wallpaper, for our use here we want to leave the user’s wallpaper alone so this process runs without altering any of the user’s settings. Click the Desktops button. Configure the Wallpaper modifications to not alter anything.   Preparing the Deployment Now we are all set for deploying the configuration to the individual machines so we can start capturing the system data. If you have not done so already, click the Apply button to create the first entry in your data repository. If all is configured correctly, you should be able to open your data file or database and see the entry for the respective machine. Now click the File > Save As menu option and save the configuration as “BGInfoCapture.bgi”.   Deploying to Client Machines Deployment to the respective client machines is pretty straightforward. No installation is required as you just need to copy the BGInfo.exe and the BGInfoCapture.bgi to each machine and place them in the same directory. Once in place, just run the command: BGInfo.exe BGInfoCapture.bgi /Timer:0 /Silent /NoLicPrompt Of course, you probably want to schedule the capture process to run on a schedule. This command creates a Scheduled Task to run the capture process at 8 AM every morning and assumes you copied the required files to the root of your C drive: SCHTASKS /Create /SC DAILY /ST 08:00 /TN “System Info” /TR “C:\BGInfo.exe C:\BGInfoCapture.bgi /Timer:0 /Silent /NoLicPrompt” Adjust as needed, but the end result is the scheduled task command should look something like this:   Download BGInfo from Sysinternals Latest Features How-To Geek ETC How To Create Your Own Custom ASCII Art from Any Image How To Process Camera Raw Without Paying for Adobe Photoshop How Do You Block Annoying Text Message (SMS) Spam?

  • Network Bridging for WiFi-to-Ethernet in linux

    - by shakaran
    It is possible Network Bridging for WiFi-to-Ethernet in linux instead of Ethernet-to-Ethernet? I have a CentOS 6.3 machine. I am using KVM and I want perform a brigde for virtualize more machines. This machine is connected only via wireless connection and it doesn't have a ethernet connection. So, I did a bridge over the WiFi interface like: # cat /etc/sysconfig/network-scripts/ifcfg-br0 DEVICE="br0" NM_CONTROLLED="yes" ONBOOT=yes TYPE=Bridge BOOTPROTO=none IPADDR=192.168.1.50 PREFIX=24 GATEWAY=192.168.1.1 DNS1=8.8.8.8 DNS2=8.8.4.4 DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System br0" Then I edit my wireless conection like: # cat /etc/sysconfig/network-scripts/ifcfg-mywireless ESSID="mywireless" MODE=Managed KEY_MGMT=WPA-PSK WPA_ALLOW_WPA2=yes CIPHER_PAIRWISE=CCMP CIPHER_GROUP=CCMP TYPE=Wireless #BOOTPROTO=none #IPADDR=192.168.1.50 #PREFIX=24 #GATEWAY=192.168.1.1 #DNS1=8.8.8.8 #DNS2=8.8.4.4 DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="Auto mywireless" UUID=874***** ONBOOT=yes LAST_CONNECT=1355923469 BRIDGE=br0 After, I restart the network: # /etc/init.d/network restart Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface Auto_mywireless: Error: Unknown connection: 874***** [FAILED] Bringing up interface br0: [ OK ] But as you can see, it show a error. My ifconfig output shows now: # ifconfig br0 Link encap:Ethernet HWaddr 6E:20:AD:CE:D8:AB inet addr:192.168.1.50 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::6c20:adff:fece:d8ab/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:67 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:6393 (6.2 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:432 errors:0 dropped:0 overruns:0 frame:0 TX packets:432 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:62433 (60.9 KiB) TX bytes:62433 (60.9 KiB) ra0 Link encap:Ethernet HWaddr 00:22:F7:2B:87:E5 inet addr:192.168.1.42 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::222:f7ff:fe2b:87e5/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:46 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:487894880 (465.2 MiB) TX bytes:148136473 (141.2 MiB) virbr0 Link encap:Ethernet HWaddr 52:54:00:5B:30:9A inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:70 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:5838 (5.7 KiB) But this doesn't give internet connection and I loss access to 192.168.1.50. So, it is possible setup this networking bridge WiFi-to-Ethernet?

  • File/printer sharing issues on network with multiple OSes

    - by DanZ
    My workplace consists of computers running a variety of different operating systems, and I have been running into problems getting some of them to connect to a shared drive and printer over the network. Here is a brief description of the computers involved and the issues I have encountered: 1: Dell desktop, Windows Vista Business-- This is the computer I want the others to connect to. It has a USB printer and eSATA hard drive enclosure that I have set up for sharing, with different accounts for the various users. 2: Fujitsu laptop, Windows XP Tablet edition-- No problems. Can connect to both the shared printer and hard drive. 3: Lenovo laptop, Windows Vista Business 64 bit-- No problems. Can connect to both the shared printer and drive. 4: Apple MacBook, OS 10.4-- Can connect to the shared drive, but not to the shared printer. I am aware that the printer issue is due to a known incompatibility between Vista and OS 10.4 and earlier with regards to Samba. It is not a big problem, however, as this computer can access a network printer. 5: Sony laptop, Windows Vista Home Premium-- Can connect to the shared printer, but not the shared drive. It can see computer 1 and its shared drive on the network, and appears to successfully log in to user accounts. However, if you try to access the shared drive, it says you do not have permission. I have tried both standard and administrator accounts, and none can access the drive from this computer. 6: MacBook Pro, OS 10.5 (there are two of these)-- Can connect to the shared printer, but not the shared drive. They can't see computer 1 on the network. For that matter, they also can't see each other or the older Mac, but can see and access shared folders on the XP machine (computer 2) and can see other PCs in the building. I was able to add the shared printer manually by typing in its network location, but was unable to manually add the shared drive in the same way. So, what I am looking for is suggestions on how to get computers 5 and 6 to connect to the shared drive. Since they can already connect to the shared printer (which is on the same computer as the shared drive), it seems reasonable that they should be able to access the drive as well.

  • HTTP downloads stop after some time, resuming is not possible

    - by cdauth
    When I try to download a file via HTTP, the downloads sometimes stop after around 30 MB. The download rates goes down to 0 B/s and no data keeps coming. When I stop the download and resume again, the download still hangs. But when I redownload it from byte 0 again, everything works fine up to 30 MB when it stops again. Sometimes, after some hours, it just works again without problems. The position in the file when the download stops is variable, but most of the time it is around 30–35 MB. As a download manager I use wget. The same behaviour happens though using curl and other download managers. The error occurs independently of the server I download from. I have also observed this error on other Linux computers in my network. All computers on my network run Gentoo Linux on x86. All internet connections on my network go through a server on my network which runs a transparent Squid proxy on port 80. That server is connected to a router, which is a Speedport W 700V by Deutsche Telekom AG. That router is connected to the internet using ADSL, with 448 kbit/s down speed and 96 kbit/s up speed. I am almost sure that my transparent proxy is not the problem. I turned that off without resolving the issue. I also connected to the router directly via WLAN without resolving the issue. I also tried to download over another port via HTTP. Furthermore, I tried to download the file using IPv6 with a gateway6 tunnel from my computer, which resulted in exactly the same problem. Now the strange thing is that everything works fine using FTP and HTTPS (also with wget on the same computer). Even more strange: when I resume the download that hanged over HTTP using FTP or HTTPS, download a few bytes that way, stop wget and then resume again using HTTP, it loads data again! But after a few MB, it may stop again. Unfortunately, files downloaded that way are always broken (the MD5 sum is not correct), so at some point, there must have been bogus data. I tried searching for HTML error messages in the downloaded file, but grep -i html does not find anything. (I cannot think of a way to search for GZIP-compressed HTML error messages in the file, so I did not try that.) I tried using strace on wget when it failed to resume a download, you can find the entire output on pastebin. The important lines are repeated every second: clock_gettime(CLOCK_MONOTONIC, {326102, 62176435}) = 0 ) = 1 write(2, "78% [++++++++++++++++++++++++++++"..., 19578% [+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ] 110,683,685 --.-K/s ) = 195 select(4, [3], NULL, NULL, {0, 949999}) = 0 (Timeout) I have absolutely no idea what could be the reason of this problem. It seems like whatever causes the issue speaks HTTP. It seems to speak HTTP that intelligently that it even regognises it in an IPv6-over-IPv4 tunnel. But what could that be and why does it only happen sometimes? The other possibility would be that there is a problem on my computer that is the same on other Gentoo Linux computers as well. Has anyone ever had such a problem? What could be the reason and where do I have to continue investigating to find out more about the issue? Update: I have just run into the problem again and tried to resume the download over the router’s WLAN, and this time it worked. Maybe I did something wrong during my last tests with the WLAN. Now maybe my transparent proxy server is in fact the problem. It is a very basic Squid proxy server that does not cache anything. Maybe the fact is interesting that a second Squid proxy runs on the same computer on another port. Update: A download hung again and this time I turned off all firewall settings and stopped all proxy servers. I failed to resume the download from my network server, which is directly connected to the router. So my proxy server definitely is not the cause the problem. I will try to upgrade the firmware of my router now, although I do not have admin access to it. I will see what I can do.

  • Cannot access website from inside network

    - by musclez
    I have a website running from my internal network available at the example IP 192.168.1.5. When I type this in to the browser, it redirects to my domain name ie, "example.com", and gives me Error code: ERR_CONNECTION_REFUSED. Any other machine that is inside of the network can access the website. The website is also accessible outside of the network. Other services from the server, like file sharing or ftp, are available to all machines in the network including the one i'm having issues http issues with. The issue may be linked to a proxy service, but from my understanding the service has been completely disabled and any executable have been uninstalled from the machine. I am wondering if there is some residual proxy information remaining on the machine that limits the connection. I'm fairly positive that "example.com" is what is being blocked by the local machine, and not an IP address being blocked or a faulty connection. When I examine the hosts file, there are no redirects to the local machine for "example.com". There was a rule, as on my other machines within the network: 192.168.1.5 example.com But i have since removed that for troubleshooting purposes. What intrigued me is that when I use the actual IP, the IP address will redirect to the domain in the browser and THEN say ERR_CONNECTION_REFUSED. Server-Side Results The server logs are reporting this: example.com ::1 - - [Date & time] "OPTIONS * HTTP/1.0" 200 126 "-" "Apache/2. 2.22 (Unix) (internal dummy connection)" However, this seems to be irrelevant as it is not triggered when I try to connect to the server with the specified machine. Fiddler results: Host: *example.com* Proxy-Connection: keep-alive Chrome-Side [Fiddler] The connection to 'example.com' failed. Error: ConnectionRefused (0x274d). System.Net.Sockets. SocketException No connection could be made because the target machine actively refused it 01.23.45.67:80 01.23.45.67:80 would be the external IP, which the server and the machine in question both share. I am doing so reading into 0x274d and its coming back with .NET web.config information. I am still at a loss to what to do with this information. I have WireShark running as well. Theres is a lot of sensitive information in the readout and I'm not sure what to extract from it. Either way, if it helps, I can access that information if anyone would like me to. Thanks for the help!

  • Design pattern for client/server sessions?

    - by nonot1
    Are there any common patterns or general guidance I can learn from for how to design a client/server system where the both the client and server must maintain some kind per-client session state? I've found any number of libraries that can help with some of the plumbing, but it's the overall design I'm wondering about. Open issues in my mind: How to structure the client/server communication so that bidirectional synchronous and asynchronous requests are possible? The server side needs to spawn a couple of per-connected-client session-long helper process. How to manage that? How to manage the mapping from a given client (and any of it's requests) to server state and helper process instances in the face of multiple clients and intermittent network connectivity. Most communication can be simple blocking request/reply, but some will be long running processing tasks that the client will want to keep tabs on. To the extent that it matters, the platform is Linux/C/C++. Not web based. Just an existing thick-client software app being modified to talk to backend servers for some tasks.

  • Slow boot on Ubuntu 12.04, probable cause the network connection

    - by Ravi S Ghosh
    I have been having rather slow boot on Ubuntu 12.04.

  • How Microsoft Market DotNet?

    - by Fendy
    I just read an Joel's article about Microsoft's breaking change (non-backwards compatibility) with dot net's introduction. It is interesting and explicitly reflected the condition during that time. But now almost 10 years has passed. The breaking change It is mainly on how bad is Microsoft introducing non-backwards compatibility development tools, such as dot net, instead of improving the already-widely used asp classic or VB6. As much have known, dot net is not natively embedded in windows XP (yes in vista or 7), so in order to use the .net apps, you need to install the .net framework of over 300mb (it's big that day). However, as we see that nowadays many business use .net as their main development tools, with asp.net or mvc as their web-based applications. C# nowadays be one of tops programming languages (the most questions in stackoverflow). The more interesing part is, win32api still alive even there is newer technology out there (and still widely used). Imagine if microsoft does not introduce the breaking change, there will many corporates still uses asp classic or vb-based applications (there still is, but not that much). There are many corporates use additional services such as azure or sharepoint (beside how expensive is it). Please note that I also know there are many flagships applications (maybe adobe's and blizzard's) still use C-based or older language and not porting to newer high-level language. The question How can Microsoft persuade the users to migrate their old applications into dot net? As we have known it is very hard and give no immediate value when rewrite the applications (netscape story), and it is very risky. I am more interested in Microsoft's way and not opinion such as "because dot net is OOP, or dot net is dll-embedable, etc". This question may be constructive, as the technology is vastly changes over times lately. As we can see, Microsoft changes Asp.Net webform to MVC, winform is legacy now, it is starting to change to use windows store rather than basic-installment, touchscreen and later on we will have see-through applications such as google class. And that will be breaking changes. We will need to account portability as an issue nowadays. We will need other than just mere technology choice, but also migration plans. Even maybe as critical as we might need multiplatform language compiler, as approached by Joel's Wasabi. (hey, I read his articles too much!)

  • File/printer sharing issues on network with multiple OSes

    - by DanZ
    My workplace consists of computers running a variety of different operating systems, and I have been running into problems getting some of them to connect to a shared drive and printer over the network. Here is a brief description of the computers involved and the issues I have encountered: 1: Dell desktop, Windows Vista Business-- This is the computer I want the others to connect to. It has a USB printer and eSATA hard drive enclosure that I have set up for sharing, with different accounts for the various users. 2: Fujitsu laptop, Windows XP Tablet edition-- No problems. Can connect to both the shared printer and hard drive. 3: Lenovo laptop, Windows Vista Business 64 bit-- No problems. Can connect to both the shared printer and drive. 4: Apple MacBook, OS 10.4-- Can connect to the shared drive, but not to the shared printer. I am aware that the printer issue is due to a known incompatibility between Vista and OS 10.4 and earlier with regards to Samba. It is not a big problem, however, as this computer can access a network printer. 5: Sony laptop, Windows Vista Home Premium-- Can connect to the shared printer, but not the shared drive. It can see computer 1 and its shared drive on the network, and appears to successfully log in to user accounts. However, if you try to access the shared drive, it says you do not have permission. I have tried both standard and administrator accounts, and none can access the drive from this computer. 6: MacBook Pro, OS 10.5 (there are two of these)-- Can connect to the shared printer, but not the shared drive. They can't see computer 1 on the network. For that matter, they also can't see each other or the older Mac, but can see and access shared folders on the XP machine (computer 2) and can see other PCs in the building. I was able to add the shared printer manually by typing in its network location, but was unable to manually add the shared drive in the same way. So, what I am looking for is suggestions on how to get computers 5 and 6 to connect to the shared drive. Since they can already connect to the shared printer (which is on the same computer as the shared drive), it seems reasonable that they should be able to access the drive as well.

  • Transient network dropout for Xen DomU's

    - by Stephen C
    We've got a CentOS server running a cluster of virtuals. Occasionally the cluster's internal network drops out for a minute or so ... and then comes back. The problem is somehow related to the actual network traffic, but it is not a simple load issue. (The system is generally lightly loaded, and the problem occurs irrespective of actual load.) The setup: CentOS 5.6 on Dom0, various CentOS on the DomU's Hardware - a Dell R710 with a BroadCom NextXpress 2 NIC (sigh) using the latest drivers for the NIC from BroadCom Xen configured to use network-bridge and vif-bridge Some iptable tweaks to route an unrelated port to one of the virtuals. The system has one externally visible IP address, and Dom0 runs an Apache httpd configured with a number of virtual hosts each of which reverse proxies to web servers running on the virtuals. (The virtuals have to be NAT'ed, primarily because we don't have enough allocated public IP addresses.) The symptoms: Works fine most of the time. When someone tries to UPLOAD a large file to one virtuals, the internal network drops out ... for all virtuals: The Dom0 httpd sees a network timeout talking to the backend server on the virtual and reports a 502. A previously established ssh connection from Dom0 to any of the DomU's freezes. Our monitoring shows ping failures for traffic between virtuals. The Xen consoles to the DomU's do not freeze. No log messages in any log files that I can see, on either Dom0 or the DomU's ... apart from the Dom0 httpd logs. After a minute or so, the problem clears by itself. This is 100% reproducible. What we've tried: Downloading, building and installing the latest BNX2 driver on Dom0 Turning off MSI on the NIC - adding "options bnx2 disable_msi=1" to /etc/modprobe.conf Turning off tcp segmentation offload - "ethtool -K eth0 tso off". Sacrificing a black rooster at midnight. I've exhausted all my options apart from switching to KVM ... or slaughtering more roosters. Any suggestions?

  • D-Link DIR-300 slows down / loses network

    - by basic6
    there are 2 buildings (A and B). In bldg A is an open WLAN (which I'm allowed to use btw). In bldg B is a computer that I want to connect to that network. So I flashed an old D-Link DIR-300 AP with DD-WRT, mounted it to the wall (bldg B) near a window, attached a 13 dBi directional antenna (pointing to bldg A) and configured it as AP client in that wireless network. Then there's another AP, connected to the D-Link AP, acting as standard access point, which the computer is connected to. That's basically working so far, but: Every now and then the connection is lost. Not the connection between the computer and the D-Link (I can access the DD-WRT admin page normally) or the connection between the D-Link and the WLAN (in Status - Wireless it says it's still connected to the network), but when I want to access a web page (which only works if I'm connected to the wireless network from bldg A), my Firefox keeps "Looking for" (name resolution) without finding anything. When I reset the D-Link (power off, power on) in this situation, after some moments, everything's working fine again (Internet access). I've no idea why this is happening, but usually it's at most every few weeks (most times when nobody was using the computer, so no traffic). Compared to the connection speed when I connect directly to the WLAN in bldg A (Laptop), the speed in bldg B is rather slow, but I have the impression that this difference is worse in the last few days. A few minutes ago, I got 582 KB/s down and 911 KB/s up in bldg A (directly/laptop) and 84 KB/s down and 9 KB/s up in bldg B. The speed in bldg B used to be way higher (I remember 200 KB/s up) while the actual network speed in bldg A was lower than it is now (close to those 200). I'm aware that the wireless connection between those buildings should slow things down, but I'm wondering why this difference has become that extreme. Thanks for any tips... Update: I currently want to upload a large file (1.5 GB) via FTP (FileZilla). Since that caused the D-Link to disconnect (as described in first post), I took my laptop to bldg A, connected directly to the original WLAN (bypassing my D-Link) and tried the same upload. Guess what - same issue: At some point the connection is dead (at this point I would have reset my D-Link if I was connected to it). Just as the D-Link, my laptop is still connected, but not even name resolution is working ("Looking for..." in Firefox). After reconnecting, it's working again. Maybe my D-Link isn't the problem at all...

  • What Software or tool to ease the building of an eye catching GUI (functional) [closed]

    - by CaBieberach
    I want to make a control panel that opens different files but I'm not sure what would be the right tool/Sw to make this. In the company we have about 30 files that we use almost every day. They are all related to each other. I would like to create a "Control panel" to ease the opening and searching of these files. Kind of a control panel with 30 buttons. The only duty of this control panel is to open one of the file selected by the user. I need this "Control Panel" to: Look GREAT Open very fast Could you please recomend me some tool/Sw to acomplish this. What tool or SW is specially focused to make stunning GUIs? Note: In the company We are all using MS Windos 7. Thanks for the help! EDIT: This would be a Stand alone program installed or saved in a network drive. Each person can open the porgram and it pops the GUI. Not for the web. "Looks GREAT" is definitively a subjective matter. I want something that gives me plenty options to display/modify the objetcs that compose the GUI. So i can experiment and find what looks and works the best.

  • Why is Java the lingua franca at so many institutions?

    - by Billy ONeal
    EDIT: This question at first seems to be bashing Java, and I guess at this point it is a bit. However, the bigger point I am trying to make is why any one single language is chosen as the one end all be all solution to all problems. Java happens to be the one that's used so that's the one I had to beat on here, but I'm not intentionality ripping Java a new one :) I don't like Java in most academic settings. I'm not saying the language itself is bad -- it has several extremely desirable aspects, most importantly the ability to run without recompilation on most any platform. Nothing wrong with using the language for Your Next App ^TM. (Not something I would personally do, but that's more because I have less experience with it, rather than it's design being poor) I think it is a waste that high level CS courses are taught using Java as a language. Too many of my co-students cannot program worth a damn, because they don't know how to work in a non-garbage-collected world. They don't fundamentally understand the machines they are programming for. When someone can work outside of a garbage collected world, they can work inside of one, but not vice versa. GC is a tool, not a crutch. But the way it is used to teach computer science students is a as a crutch. Computer science should not teach an entire suite of courses tailored to a single language. Students leave with the idea that all good design is idiomatic Java design, and that Object Oriented Design is the ONE TRUE WAY THAT IS THE ONLY WAY THINGS CAN BE DONE. Other languages, at least one of them not being a garbage collected language, should be used in teaching, in order to give the graduate a better understanding of the machines. It is an embarrassment that somebody with a PHD in CS from a respected institution cannot program their way out of a paper bag. What's worse, is that when I talk to those CS professors who actually do understand how things operate, they share feelings like this, that we're doing a disservice to our students by doing everything in Java. (Note that the above would be the same if I replaced it with any other language, generally using a single language is the problem, not Java itself) In total, I feel I can no longer respect any kind of degree at all -- when I can't see those around me able to program their way out of fizzbuzz problems. Why/how did it get to be this way?

  • Do functional generics exist and what is the correct name for them if they do?

    - by voroninp
    Consider the following generic class: public class EntityChangeInfo<EntityType,TEntityKey> { ChangeTypeEnum ChangeType {get;} TEntityKeyType EntityKey {get;} } Here EntityType unambiguously defines TEntityKeyType. So it would be nice to have some kind of types' map: public class EntityChangeInfo<EntityType,TEntityKey> with map < [ EntityType : Person -> TEntityKeyType : int] [ EntityType : Car -> TEntityKeyType : CarIdType ]> { ChangeTypeEnum ChangeType {get;} TEntityKeyType EntityKey {get;} } Another one example is: public class Foo<TIn> with map < [TIn : Person -> TOut1 : string, TOut2 : int, ..., TOutN : double ] [TIn : Car -> TOut1 : int, TOut2 :int, ..., TOutN : Price ] > { TOut1 Prop1 {get;set;} TOut2 Prop2 {get;set;} ... TOutN PropN {get;set;} } The reasonable question: how can this be interpreted by the compiler? Well, for me it is just the shortcut for two structurally similar classes: public sealed class Foo<Person> { string Prop1 {get;set;} int Prop2 {get;set;} ... double PropN {get;set;} } public sealed class Foo<Car> { int Prop1 {get;set;} int Prop2 {get;set;} ... Price PropN {get;set;} } But besides this we could imaging some update of the Foo<>: public class Foo<TIn> with map < [TIn : Person -> TOut1 : string, TOut2 : int, ..., TOutN : double ] [TIn : Car -> TOut1 : int, TOut2 :int, ..., TOutN : Price ] > { TOut1 Prop1 {get;set;} TOut2 Prop2 {get;set;} ... TOutN PropN {get;set;} public override string ToString() { return string.Format("prop1={0}, prop2={1},...propN={N-1}, Prop1, Prop2,...,PropN); } } This all can seem quite superficial but the idea came when I was designing the messages for our system. The very first class. Many messages with the same structure should be discriminated by the EntityType. So the question is whether such construct exists in any programming language?

  • Simulate Network Presence in dbus

    - by Evans
    Is there a way using Python to simulate the presence of an active network connection using dbus? If I call getstate() on the dbus, I'm able to get the current network state. I want to set the current state to 4 (Connection Present). This is because Network Manager is not able to connect using my modem and I use other tools to connect. Pidgin, Empathy and other software are not able to detect the network.

  • Smallest sum of graph weight, where each node are connceted (like a network)

    - by Svisstack
    Hello, What algorithm I can use for problem like this: Have a graph positive weighted, i want to know a smallest possible sum of weights where each node are connected (connected like a network, where each node is a eg. network device). In this network each node can be connected with other node by some other other nodes in way. But all nodes from input graph must be in a network. Any one can help me with this?

  • Mapping Drive Error - System Error 1808

    - by Julian Easterling
    A vendor is attempting to map and preserve a network drive using nt authority/system; so it stays persistent when the interactive session of the server is lost. They were able to do this on one server (Windows 2008 R2) but not a second computer (also Windows 2008 R2).

  • Existing open source software for wireless mesh networking?

    - by user70352
    Hello! My goal: Build a wireless mesh network with some ALIX 2D2 (500 MHz AMD Geode LX800 x86 CPU, 256MB RAM, Atheros wireless card) Aside from working like a normal wireless mesh network users should be able to read/write data from/to the ALIX Boxes and the ALIX boxes should be able to process data. Questions: Should I try to flash dd-wrt x86, voyage linux (linux.voyage.hk) or something else? What (open source) software should I look into before I start? Should I use a 'server' for data storage and processing instead of the ALIX boxes? Is it even possible to use the ALIX boxes for routing AND data storage and processing? Final notes: Data can be anything, for example, I want to setup a wireless mesh using the OLSRD protocol so my whole town gets wifi and can access songs on the network. It's not for that, but that's the idea. I'm not afraid of programing, compiling or working with *nix. This is mostly 'for fun' rather than for practicality. Thanks in advance for any feedback.

  • "No more threads can be created in the system" in Network and Sharing Center

    - by Zell Faze
    A while back I noticed on one of our laboratory computers (Windows 7, very little extra software installed) that the network connection icon in the system tray would claim that it had no network connection, even though it did. This issue would go away after the computer was rebooted, but would surface again the next time I looked at the computer (a few days later). Upon opening the Network and Sharing Center I am shown an actual error message, but not one that seems to give me a lot of information about what the problem is. In the place of the usual information about network adapters and whether you are connected to the Internet it simply says: "No more threads can be created in the system." The Event Viewer shows hundreds of events from different services also with the same message. "Volume Shadow Copy Service error: Unexpected error calling routine CoCreateInstance. hr = 0x800700a4, No more threads can be created in the system."; "The WinHTTP Web Proxy Auto-Discovery Service service failed to start due to the following error: A thread could not be created for the service."; "The IP Helper service terminated with the following error: No more threads can be created in the system." As far as I can tell, this message seems to mean that there is some sort of resource leak in Windows where something is creating a large number of threads and those threads are not being killed off? I've tried restarting WMI and several services related to networking, without avail. Can anyone provide more information on what "No more threads can be created in the system" might mean and what I might be able to do to fix the issue? Currently the only solution appears to be restarting.

  • Accessing network shares on Windows7 via SonicWall VPN client

    - by Jack Lloyd
    I'm running Windows7 x64 (fully patched) and the SonicWall 4.2.6.0305 client (64-bit, claims to support Windows7). I can login to the VPN and access network resources (eg SSH to a machine that lives behind the VPN). However I cannot seem to be able to access shared filesystems. Windows is refusing to do discovery on the VPN network. I suspect part of the problem is Windows persistently considers the VPN connection to be a 'public network'. Normally, you can open the network and sharing center and modify this setting, however it does not give me a choice for the VPN. So I did the expedient thing and turned on file sharing for public networks. I also disabled the Windows firewall for good measure. Still no luck. I can access the server directly by putting \\192.168.1.240 in the taskbar, which brings up the list of shares on the server. However, trying to open any of the shares simply tells me "Windows cannot access \\192.168.1.240\share You do not have permission to access ..."; it never asks for a domain password. I also tried Windows7 native VPN functionality - it couldn't successfully connect to the VPN at all. I suspect this is because SonicWall is using some obnoxious special/undocumented authentication system; I had similar problems trying to connect on Linux with the normal IPsec tools there. What magical invocation or control panel option am I missing that will let this work? Are there any reasonable debugging strategies? I'm feeling quite frustrated at Windows tendency to not give me much useful information that might let me understand what it is trying to do and what is going wrong.

  • Is fish or zsh better for shell programming?

    - by Julien Nicoulaud
    I'm a bash user willing to switch to a more friendly and advanced shell. I read a lot of good things about zsh, but I gave a quick test at fish and it seems great too. Both seem very close in term of features, what is your opinion about those two shells especially as regards shell programming?

  • Intel Wireless 4965AGN not achieving N throughput when connected to an Airport Express N network

    - by BenA
    I have an Intel Wireless WiFi Link 4965AGN adaptor in my laptop (HP Pavillion dv2000 series) which is connecting to a 5Ghz-only 802.11n network provided by an Apple Airport Express. The network is using WPA2 encryption. My desktop is also connected the Airport, via a Linksys WUSB600N USB adaptor. Both are running with the latest drivers, and the Airport is running the latest firmware. The Airport is also configured to use wide channels. The problem I have is that I never get throughput above 4MB/s when transferring files between the two machines. Even a pessimistic calculation shows a 270Mbps network as being capable of transfer rates at well above 10MB/s. I'm pretty sure I've isolated the issue to being the Intel adaptor, as wiring the desktop to the AP, and using the Linksys adaptor on the laptop immediately yielded speeds limited by the 100MB/s ethernet connection. I know that 802.11n is still a draft standard, and so mixing kit from different manufacturers can easily lead to poor results, but I was just wondering if anybody else out there has had success with this Intel adaptor on an N network? Or even better, connecting it to an Airport Express? Can anybody give me any advice on how to troubleshoot this issue? I should also mention that the Airport Express doesn't allow you to manually specify channels when running in N mode, and that I've been able to rule out interference from other Wireless LANs by scanning. There aren't any other 5GHz networks in my area. All ideas welcome! Update: A while later, I've just updated to the most recent drivers for both the Intel chip in the laptop, and the USB adaptor. Unfortunately this hasn't improved things :(. If anybody has any advice it would be be gratefully received.
