  • How to get a stable, snappy UI using threads?

    - by Thomas Ahle
    I recently watching this video on Google Chrome with great interest. It explains that Google Chrome uses one thread for IO, one for opening files and one for intermodule communication. I think I may be able to use something similar for my own - currently quite messy - application. I wondered if there were any good articles on best-practices or patterns for such threaded divisions of tasks?

  • Understanding omission failure in distributed systems

    - by karthik A
    The following text says this which I'm not able to quite agree : client C sends a request R to server S. The time taken by a communication link to transport R over the link is D. P is the maximum time needed by S to recieve , process and reply to R. If omission failure is assumed ; then if no reply to R is received within 2(D+P) , then C will never recieve a reply to R . Why is the time here 2(D+P). As I understand shouldn't it be 2D+P ?

  • SQL Server 2008 error message from store procedure

    - by George2
    Hello everyone, When we met with such error message from store procedure, Message 1205, Level 13, State 52, the process Pr_FooV2, Line 9 Services (Process ID 111) and another process is deadlock in the lock | communication buffer resources, and has been chosen as the deadlock victim. Rerun the transaction. I am wondering whether such messages are stored in log files? I searched log folder of my SQL Server 2008 installation root (in my environment, it is C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Log), but can not find such files. thanks in avdance, George

    Hey SO Doing a some practice questions for exam tomorrow can't figure out this one What is the minimum number of socket port(s) required for a TCP server to connect a TCP client for communication? Surely its just two right? one for the server one for the client, but this seems to obvious. My mates thinks TCP uses two ports at the server end for for data in and one for data out. thanks in advance

  • find the top K most frequent numbers in a data stream

    - by Jin
    This is more of a data structure question rather than a coding question. If I am fetching a data stream, i.e, I keep receiving float numbers once at a time, how should I keep track of the top K frequent numbers? Here my memory is 4G and I prefer to have less communication with hard drive unless necessary. I think heap is good for updating the max and min. How should I design the data structure? Thanks

  • Killing a thread while deleting an object

    - by viswanathan
    I have an application which does some socket communication with some hardwares. Assume for the particular hardware i have an object and this object intiates a thread which listens on a particular port number say 5001 infinitely until a connection is established. Now if i delete this obect is there anyway by which i can ensure that the thread that is listening on port number 5001 infinitely also gets destroyed.

My program shouldn't use AJAX and timers. Please Help.

  • [Python] How to create a named temporary file in memory?

    - by conradlee
    I would like to use Python's tempfile module to create a temporary file that I will use for communication between processes (use of pipes is awkward). The documentation I've linked to above shows two functions that almost do what I want: tempfile.NamedTemporaryFile # For creating named tempfiles tempfile.SpooledTemporaryFile # For creating tempfiles in memory but actually I want a tempfile that is both named AND in memory. Any ideas?

    I want to set a route :requirements on an array that verifies a particular parameter is included in an array: atypes = [:culture, :personality, :communication] map.with_options(:path_prefix = ':atype', :requirements = {:atype = atypes.include?(:atype)}) do |assessment| ... end I haven't been able to find any documentation on how to accomplish this. Any help would be appreciated.

  • What to check to see if server has enough free resources?

    - by kyrisu
    The windows service I am writing will need to run some processor intensive operations once in a while (sound encoding wav - mp3) on a machine that takes part in real time voice communication (so I cannot just run them any-time). What would you check (what counters maybe) before running such operation? Can you point me to any good articles?

  • Maintaining many socket connections with a single thread

    - by John
    Many tutorials on socket communication I see seem to use 1 thread per socket. But on a server used for online gaming, you might have 10k concurrent users - 10k threads isn't probably a wonderful idea. I came across a tool (SmartFox) which claims to use a single thread for monitoring all socket connections, potentially thousands of them. This app happens to be in Java, but I figure C++ or C# could do the same... how would you achieve this?

  • How to send stream data via Bluetooth from an iPhone/iPod Touch to a Windows C++ application?

    - by PLinhol
    Hello, I need to develop an iPhone/iPod Touch application that creates a server to send some data stream (characters or bytes) to a Windows C++ application via Bluetooth. I'm thinking of creating a TCP connection, but don't know where to start. What iPhone API should I use do to something like this? Does anyone knows some code examples that i can use to do this? And in Windows, what should I use to support this kind of communication? Thanks

  • SOAP vs REST (differences)

    - by Abdulaziz
    I have read articles about the differences between SOAP and REST as a web service communication protocol, but I think that the biggest advantage for REST over SOAP are : REST is more dynamic, no need for creating and updating UDDI. REST is not restricted to XML format. REST web services can send plain text, JSON, and also XML. But SOAP is more standardized (Ex; security). So, am I correct in these points? Thanks

  • How can I create proportionally-sized pie charts side-by-side in Excel 2007?

    - by Andrew Doran
    I have a pivot table with two sets of data as follows: 2011 2012 Slice A 45 20 Slice B 33 28 Slice C 22 2 I am trying to present two pie charts side-by-side, one with the 2011 data and one with the 2012 data. I want the relative size of each pie chart to reflect the totals, i.e. the pie chart with the 2011 data (totalling 100) should be twice the size of the pie chart with the 2012 data (totalling 50). The 'pie of pie' chart type seems to be closest to what I am looking for but this breaks out data from one slice and presents it in a second diagram so it isn't appropriate here.

  • Motherboard wiring

    - by ML
    I am putting a new motherboard in a chenbro chasis and I dont get how to plugin the wires for powerSW resetSW, etc. It is a SuperMicro P4DP6 motherboard. ** I cant post an image yet, but here is a long to the spot on the mobo where this goes: http://andrewslack.info/mobo.png The powerSW lead is a green and white wire. I have the wire for PowerSW in place as the white wire ground and I have tried the reverse even (green to ground). The wire is covering Pin 1 and 2 in the diagram And I press the power button on the machine and nothing happens. It worked before I replaced the motherboard, the 24-pin ATX power leas is connected as well as the 2dn 6-pin optional power. Thoughts?

  • MySql Replication with a star topology

    - by Riotopsys
    My company currently operates in 3 separate locations connected by slow vpn links. Each site hosts a dedicated MySql server. I need to aggregate the data from all three of them onto a single server for corporate reporting. The powers that be have stated I cannot use circular replication or federated tables. Is there a third party tool for MySql that can replicate from multiple masters? Basically the diagram would be a daisy with the reporting server slave at center with multiple replication connections coming in from the master sites on the petals.
