  • cheap gigabit switch for small business

    - by neoice
    my friend's business is currently borrowing my Adtran 1224R and is very happy with it. it's configured with a few VLANs to segment customers, internal traffic and public wifi. port 1 is a "trunk" port to the router, a chunky Linux box with iptables+NAT. they push a lot of traffic over the LAN (data backups) and really need gigabit. besides, I'd like my Adtran back :P my goal is to find a cheap(ish) switch that can function as a drop-in replacement. it looks like VLAN trunking is actually part of the 802.1q spec, so anything with VLAN support should cover the current trunk-to-router setup. it's nice to have both a web interface and SSH, but I can configure it either way if needed. things like the Netgear GS724T have caught my eye, but it seems like none of the hardware in the $300-500 range have really solid reviews. I'm concerned that "cheaper" hardware might not work for a network full of power users. does anyone have a recommendation for the Netgear GS724T or a switch that will meet my needs?

  • Unable to connect to sharedfax error

    - by Owl
    I'm running SBS2k on a machine with a 56k modem for all outgoing faxes. We have a terminal server running server 2003 enterprise and in printers the sharedfax shows "unable to connect status". When you right-click, properties, it gives you an error saying the spool service is not running and you cannot view properties. The spooler service is indeed running on the 2k3 server because I can view the other printer's properties..and on 2k I show the Microsoft Shared Fax service AND Print Spooler as started. Here's the tricky part, I can add the shared fax printer on a domain computer locally (Windows XP) and it will show ready status and I can send faxes, they show up on the 2k server's fax console manager as in progress. I've sent a couple from a few different workstations today successfully, but still unable to send from 2k3 terminal services.

  • Netbook screen too small, Software fix?

    - by LantisGaius
    I have a netbook with a maximum screen resolution of 1024x600. I'm running a dualboot Ubuntu10.10 & Backtrack4r2, and I'm having some trouble with windows whose "height" was larger than 600px. Buttons end up below the screen, and I can't click 'Ok' or 'Cancel' or 'Apply'. When my OS was still Windows7, I didn't have any problems because I can resize all of the windows that I use. Most of windows in linux (esp. in KDE settings), the windows has a fixed height. Is there any workarounds to my problem?

  • Is S3 cheaper than a EC2 DIY solution (for small files)

    - by Jann
    Is it really cheaper to host images and scripts via S3 than with an EC2 instance running nginx/varnish/etc. ? It seems to me (but i'm just getting started with AWS) that the request costs will be the major factor if you don't use sprites or other optimizations... or am i missing something ?

  • Converting an Small Business Server to a Workstation

    - by noway
    I am planning to buy a Dell PowerEdge T110 Server and convert it to workstation similar to Dell PowerEdge Precision T1700. The reasoning behind is the cost, if I do it by myself, it costs two times cheaper. However, I wonder what might go wrong in this way? The things I have thought of are: Client OSes are not officially supported. There might be some driver problems. The chasis is designed to be a server case, so there are not many useful inputs in the front side of the case. The server boots slower than usual PCs. What might else be a problem?

  • Windows XP doesn't like small subnets?

    - by erniedwork
    This totally sounds like a bug to me, because my subnet mask and IP address should be valid by all accounts. My ISP has assigned me a fixed IP address of 65.110.7.20, with a subnet mask of 255.255.255.252. Which sounds about right, because we're trying to set up a router with a /31 network - just 4 ip addresses. But when I try to set this IP and netmask up in Windows XP, I get the following error: "The combination of IP address and subnet mask are invalid. All of the bits in the host address portion of the IP address are set to 0." But they're not all set to 0. That would be a subnet mask of 255.255.255.255. Even then, that too is a valid subnet mask, consisting of a network of 1 IP address. Is there a way around this? A registry hack maybe?

  • Small Business Server 2011 and Remote access to documents

    - by Tim Long
    Assume I'm working away from the office; its a hotel computer Windows 7, Office 2010 and fast - so the best possible conditions. Using Companyweb - Every time I open a document, I have to go through the logon process - seems odd to have to do that. Is this a 'by design' feature or is something wrong with my configuration? When I do open the documents, are they being stored somewhere locally and should I be looking to delete on this computer - or are they in a temporary file?

  • IP assignment in small network

    - by nooneon
    What is the best way to assign IPs in your opinion? I've got ~100 PCs, some servers and see three ways to assign IPs: Static IPs for every PC/server Static IP reservation by MAC-address in DHCP Dynamic IPs via DHCP. Of course, you can combine them, i.e. dynamic for PCs, static for servers. But, again, what is the best way? How do you do that?

  • Suggest Cisco Router for a small company of 60-100 Users

    - by user69154
    Trying to find the right router to use - we'd like to go Cisco. We have ~60 programmers that do alot of remote server work. Will grow to 100 programmers by the end of the year. We've talked to companies that sell Cisco routers. While they make recommendations, we feel that the sales guys may be selling us an overkill solution. What kind of company (that is not linked to sales of routers) can provide a service to recommend the right kind of router for our company? There are lots of network engineers out there, but am looking for some company that focuses on advising a network solution. Any suggestions of companies are welcome.

  • Growing a small hosting company [closed]

    - by user2353007
    We currently have a few servers, 1 WHM VPS (2GB), 1 MS SQL VPS (2 GB), and 1 IIS VPS (2GB). The VPS servers are doing fine as far as uptime and response times but we would like to add the following features. 1) monitoring with load statistics 2) failover I have looked a Zabbix, Zenoss, Nagios, and a couple of other cloud solutions like monitor.us and watchdog from Zerigo. Ideally for the monitoring solution. Our current hosting company suggested we get a dedicated server or VPS and install load balancing software (not sure I like that idea). I've looked into Rackspace and Amazon load balancers which seem like the most feasible solutions for load balancers. Does anybody have any input on the monitoring and load balancing products I'm looking into? Monitoring should monitor uptime as well as give reports on memory usage, disk usage, processor usage, and which processes/websites/users are responsible for the load. It would be ideal if the load balancer worked with any IP. Not sure if either Rackspace or Amazon load balancers would allow load balancing with servers outside their datacenter. Thank you.

  • Server spec for a small business [duplicate]

    - by I'll-Be-Back
    This question already has an answer here: Can you help me with my capacity planning? 2 answers I will need to buy a decent server for Windows Server 2012 and Linux for Web server (Internal use only - Intranet). I will install ESXi with 2 or 3 VM's. There will be about 80-100 Agents at work, they will login (domain controller) on client PC in the morning (between 9:40am to 10:05am). They can only use IE browser and everything else will be locked. They will not have any storage space, no email, etc. Is this spec decent enough? 2u Supermicro 825 chassis, X9SCL-F x1 Intel E3-1290v2 16Gb DDR3 x2 Intel 520 Series 240Gb x2 2Tb Seagate Barracuda, LSi 4 port SAS raid controller

  • Transient mysqlcheck errors about "size of datafile" (file too small)

    - by Adam Backstrom
    Running mysqlcheck on a live database is giving me transient errors like this one: mydatabase.mytable error : Size of datafile is: 500719688 Should be: 501000484 error : Corrupt When I run the command again or check the table one-off using mysql, it's listed as OK. Is this just a side effect of running checks on live tables? Is it possible that data is not flushed, hence the strange discrepancy? We moved several databases this morning by shutting down mysqld on the source and rsyncing files across to the new server, but these are all MyISAM tables so I don't believe the two things are related. (But I mention it just in case.)

  • identation control while developing a small python like language

    - by sap
    Hello, Im developing a small python like language using flex, byacc (for lexical and parsing) and C++, but i have a few questions regarding scope control. just as python it uses white spaces (or tabs) for identation, not only that but i want to implement index breaking like for instance if you type "break 2" inside a while loop thats inside another while loop it would not only break from the last one but from the first loop as well (hence the number 2 after break) and so on. example: while 1 while 1 break 2 end end #after break 2 it would jump right here but since i dont have an "anti" tab character to check when a scope ends (like C for example i would just use the '}' char) i was wondering if this method would the the best: i would define a global variable, like "int tabIndex" on my yacc file that i would access in my lex file using extern. then everytime i find a tab character on my lex file i would increment that variable by 1. when parsing on my yacc file if i find a "break" keyword i would decrement by the amount typed after it from the tabIndex variable, and when i reach and EOF after compiling and i get a tabIndex != 0 i would output compilation error. now the problem is, whats the best way to see if the identation got reduced, should i read \b (backspace) chars from lex and then reduce the tabIndex variable (when the user doesnt use break)? another method to achieve this? also just another small question, i want every executable to have its starting point on the function called start() should i hardcode this onto my yacc file? sorry for the long question any help is greatly appretiated. also if someone can provide an yacc file for python would be nice as a guideline (tried looking on google and had no luck). thanks in advance.

  • Small-o(n^2) implementation of Polynomial Multiplication

    - by AlanTuring
    I'm having a little trouble with this problem that is listed at the back of my book, i'm currently in the middle of test prep but i can't seem to locate anything regarding this in the book. Anyone got an idea? A real polynomial of degree n is a function of the form f(x)=a(n)x^n+?+a1x+a0, where an,…,a1,a0 are real numbers. In computational situations, such a polynomial is represented by a sequence of its coefficients (a0,a1,…,an). Assuming that any two real numbers can be added/multiplied in O(1) time, design an o(n^2)-time algorithm to compute, given two real polynomials f(x) and g(x) both of degree n, the product h(x)=f(x)g(x). Your algorithm should **not** be based on the Fast Fourier Transform (FFT) technique. Please note it needs to be small-o(n^2), which means it complexity must be sub-quadratic. The obvious solution that i have been finding is indeed the FFT, but of course i can't use that. There is another method that i have found called convolution, where if you take polynomial A to be a signal and polynomial B to be a filter. A passed through B yields a shifted signal that has been "smoothed" by A and the resultant is A*B. This is supposed to work in O(n log n) time. Of course i am completely unsure of implementation. If anyone has any ideas of how to achieve a small-o(n^2) implementation please do share, thanks.

  • Indentation control while developing a small python like language

    - by sap
    Hello, I'm developing a small python like language using flex, byacc (for lexical and parsing) and C++, but i have a few questions regarding scope control. just as python it uses white spaces (or tabs) for indentation, not only that but i want to implement index breaking like for instance if you type "break 2" inside a while loop that's inside another while loop it would not only break from the last one but from the first loop as well (hence the number 2 after break) and so on. example: while 1 while 1 break 2 'hello world'!! #will never reach this. "!!" outputs with a newline end 'hello world again'!! #also will never reach this. again "!!" used for cout end #after break 2 it would jump right here but since I don't have an "anti" tab character to check when a scope ends (like C for example i would just use the '}' char) i was wondering if this method would the the best: I would define a global variable, like "int tabIndex" on my yacc file that i would access in my lex file using extern. then every time i find a tab character on my lex file i would increment that variable by 1. when parsing on my yacc file if i find a "break" keyword i would decrement by the amount typed after it from the tabIndex variable, and when i reach and EOF after compiling and i get a tabIndex != 0 i would output compilation error. now the problem is, whats the best way to see if the indentation got reduced, should i read \b (backspace) chars from lex and then reduce the tabIndex variable (when the user doesn't use break)? another method to achieve this? also just another small question, i want every executable to have its starting point on the function called start() should i hardcode this onto my yacc file? sorry for the long question any help is greatly appreciated. also if someone can provide an yacc file for python would be nice as a guideline (tried looking on Google and had no luck). thanks in advance.

  • forcing stack w/i 32bit when -m64 -mcmodel=small

    - by chaosless
    have C sources that must compile in 32bit and 64bit for multiple platforms. structure that takes the address of a buffer - need to fit address in a 32bit value. obviously where possible these structures will use natural sized void * or char * pointers. however for some parts an api specifies the size of these pointers as 32bit. on x86_64 linux with -m64 -mcmodel=small tboth static data and malloc()'d data fit within the 2Gb range. data on the stack, however, still starts in high memory. so given a small utility _to_32() such as: int _to_32( long l ) { int i = l & 0xffffffff; assert( i == l ); return i; } then: char *cp = malloc( 100 ); int a = _to_32( cp ); will work reliably, as would: static char buff[ 100 ]; int a = _to_32( buff ); but: char buff[ 100 ]; int a = _to_32( buff ); will fail the assert(). anyone have a solution for this without writing custom linker scripts? or any ideas how to arrange the linker section for stack data, would appear it is being put in this section in the linker script: .lbss : { *(.dynlbss) *(.lbss .lbss.* .gnu.linkonce.lb.*) *(LARGE_COMMON) } thanks!

  • Fastest XML parser for small, simple documents in Java

    - by Varkhan
    I have to objectify very simple and small XML documents (less than 1k, and it's almost SGML: no namespaces, plain UTF-8, you name it...), read from a stream, in Java. I am using JAXP to process the data from my stream into a Document object. I have tried Xerces, it's way too big and slow... I am using Dom4j, but I am still spending way too much time in org.dom4j.io.SAXReader. Does anybody out there have any suggestion on a faster, more efficient implementation, keeping in mind I have very tough CPU and memory constraints? [Edit 1] Keep in mind that my documents are very small, so the overhead of staring the parser can be important. For instance I am spending as much time in org.xml.sax.helpers.XMLReaderFactory.createXMLReader as in org.dom4j.io.SAXReader.read [Edit 2] The result has to be in Dom format, as I pass the document to decision tools that do arbitrary processing on it, like switching code based on the value of arbitrary XPaths, but also extracting lists of values packed as children of a predefined node. [Edit 3] In any case I eventually need to load/parse the complete document, since all the information it contains is going to be used at some point. (This question is related to, but different from, http://stackoverflow.com/questions/373833/best-xml-parser-for-java )

  • Should checkins be small steps or complete features?

    - by Caspin
    Two of version controls uses seem to dictate different checkin styles. distibution centric: changesets will generally reflect a complete feature. In general these checkins will be larger. This style is more user/maintainer friendly. rollback centric: changesets will be individual small steps so the history can function like an incredibly powerful undo. In general these checkins will be smaller. This style is more developer friendly. I like to use my version control as really powerful undo while while I banging away at some stubborn code/bug. In this way I'm not afraid to make drastic changes just to try out a possible solution. However, this seems to give me a fragmented file history with lots of "well that didn't work" checkins. If instead I try to have my changeset reflect complete features I loose the use of my version control software for experimentation. However, it is much easier for user/maintainers to figure out how the code is evolving. Which has great advantages for code reviews, managing multiple branches, etc. So what's a developer to do? checkin small steps or complete features?

  • wm_concat function and small characer buffer

    Hi, i have select like: select substr(account,1,4), currency, amount, module,count(*) quan, wm_concat(id) ids from all_transactions group by substr(account,1,4), currency, amount, module But sometimes COUNT(*) is more then 600. In that case i get: 'ORA-06502: PL/SQL: : character string buffer too small' Is there any way out to keep wm_concat(id) for all records? Because excluding this function for entries with big COUNT(*) is the way out.

  • Small ProgressDialog "spinner" for android

    Hi, I've been able to use the standard "ProgressDialog" for android to show that an indeterminate task is running But I'd like to use the "smaller" progress dialog "spinner" that's used for indeterminate tasks in some of the standard Android applications like the android Market (there's a small spinning circle that's actually integrated into the application window (as opposed to floating on top of it). Does anyone know how to create the smaller progress dialog (or can someone point me in the right direction)? Thanks!
