  • Which implementation of OrderedDict should be used in python2.6?

    - by Jorge Vargas
    As some of you may know in python2.7/3.2 we'll get OrderedDict with PEP372 however one of the reason the PEP existed was because everyone did their own implementation and they were all sightly incompatible. So which one of the 8 current implementations link text is backwards compatible with the 2.7 odict from python 2.7 in a way we can start using that now and depend on 2.7 in a couple of months?

  • How to receive packets on the MCU's serial port?

    - by itisravi
    Hello, Consider this code running on my microcontroller unit(MCU): while(1){ do_stuff; if(packet_from_PC) send_data_via_gpio(new_packet); //send via general purpose i/o pins else send_data_via_gpio(default_packet); do_other_stuff; } The MCU is also interfaced to a PC via a UART.Whenever the PC sends data to the MCU, the *new_packet* is sent, otherwise the *default_packet* is sent.Each packet can be 5 or more bytes with a pre defined packet structure. My question is: 1.Should i receive the entire packet from PC using inside the UART interrut service routine (ISR)? In this case, i have to implement a state machine inside the ISR to assemble the packet (which can be lengthy with if-else or switch-case blocks). 2.Detect a REQUEST command (one byte)from the PC in my ISR set a flag, diable UART interrupt alone and form the packet in my while(1) loop by polling the UART?

  • How can programmers get the quiet working environment they need? [closed]

    - by Richard
    We have an open plan office with all our programmers, web designers and client service team. Problem is my programmer team has to put up with dance music and wailing guitars all day due to the fact that designers and client services team think this makes the office a better environment. When I turn it off (by blocking the streaming of music on the router, he-he-he) they complain that its so quiet and dull. How do I explain to them that programmers need a calm quiet environment without coming across like a really annoying geek? Any other thoughts or ideas appreciated.

  • syntax to express mathematical formula concisely in your language of choice

    - by aaa
    hello. I am developing functional domain specific embedded language within C++ to translate formulas into working code as concisely and accurately as possible. Right now my language looks something like this: // implies two nested loops j=0:N, i=0,j (range(i) < j < N)[T(i,j) = (T(i,j) - T(j,i))/e(i+j)]; // implies summation over above expression sum(range(i) < j < N))[(T(i,j) - T(j,i))/e(i+j)]; I am looking for possible syntax improvements/extensions or just different ideas about expressing mathematical formulas as clearly and precisely as possible. Can you give me some syntax examples relating to my question which can be accomplished in your language of choice which consider useful. In particular, if you have some ideas about how to translate the above code segments, I would be happy to hear them Thank you

  • GA Framework for Virtual Machines

    - by PeanutPower
    Does anyone know of any .NET genetic algorithm frameworks for evolving instructions sets in virtual machines to solve abstract problems? I would be particularly interested in a framework which allows virtual machines to self propagate within a pool and evolve against a fitness function determined by a data set with "good" outputs given expected inputs.

  • Static and Dynamic Scooping Problem

    - by Devyn
    Hi, I'm solving following code in Static and Dynamic Scooping. I got following answer but I need someone to confirm if I'm correct or not since I'm a bit confusing. I really appreciate if anyone can explain in simple way! Static => (1)8 (2)27 Dynamic => (1)10 (2)27 proc main var x,y,z; proc sub1 var x,z x := 6; z := 7; sub2; x := y*z + x; print(x); ---- (2) end; proc sub2 var x,y x := 1; y := x+z+2; print(y); ---- (1) end; begin x := 1; y:=3; z:=5; sub1; end

  • How to add site search function to website using XHTML/HTML?

    - by felixd68
    I really want to learn how to make my own search engine for my site. I have the defined buttons and labels, but it doesn't search. I can't figure out the HTML or XHTML code for actually searching the site. This is the code I have so far: <p class="search"> <label>SEARCH</label> <input name="search" type="text" class="txt" /> <input name="search-btn" type="submit" class="btn" value="SEARCH" /> </p> Thanks!

  • Do you think the AI industry will ever come back?

    - by Isaiah
    I just spent some time reading about the collapse of the AI industry and realized a lot of the reason it failed was because technology was slow to catch up with their theories on when it would be available. I also read that it is believed computers that will be able to emulate human synapses may be made round 2015-2025. It's 2010 now and were getting pretty close to that time frame. I was wondering if anyone thinks that the AI industry will return as the technology lands? And if so, will it change the language market? Could Lisp like languages suddenly experience a burst of growth if it does? Idk I just thought it was interesting thinking about it.

The user has another application who does automatically make the system dial the default connection. But I can't undertand how to do it from my Compact .NET application.

  • help me understand cuda

    - by scatman
    i am having some troubles understanding threads in NVIDIA gpu architecture with cuda. please could anybody clarify these info: an 8800 gpu has 16 SMs with 8 SPs each. so we have 128 SPs. i was viewing stanford's video presentation and it was saying that every SP is capable of running 96 threads cuncurrently. does this mean that it (SP) can run 96/32=3 warps concurrently? moreover, since every SP can run 96 threads and we have 8 SPs in every SM. does this mean that every SM can run 96*8=768 threads concurrently?? but if every SM can run a single Block at a time, and the maximum number of threads in a block is 512, so what is the purpose of running 768 threads concurrently and have a max of 512 threads? a more general question is:how are blocks,threads,and warps distributed to SMs and SPs? i read that every SM gets a single block to execute at a time and threads in a block is divided into warps (32 threads), and SPs execute warps.

  • help, stuck with logic variable comparison loop, javascript

    - by Jamex
    I have an input text box for search of input, the id of the text box is: id="search". if a user enters 'cat' at first and hit search. In the function, I get the value 'cat' by using the syntax: var input = document.getElementById("search").value; After that, the user enter 'dog' in the search box and hit search using the same function. The function would assign 'dog' to the input variable. How would I compare the current value (dog) to the previously entered value (cat)? I have tried to assign the original input with a statement, something like var orig = input; but that would only overwrite the original input with the new input. What is the logical approach to this problem.

  • How do you encrypt data between client and server running in Flash and Java?

    - by ArmlessJohn
    We have a multiclient system where the client is written in Flash and the server is written in Java. Currently, communication is done in Flash by usage of flash.net.Socket and the protocol is written in JSON. The server uses a custom port to receive connections and then proceed to talk with each client. As expected, data is sent and received on both fronts as raw bytes, which are then decoded as needed. We would like to encrypt the communication between clients and server. I have some basic understanding about public/private key encryption, but I do not know what is the best way to exchange keys or what libraries are available (on both languages) to do this. What would be the best strategy to attack this problem and where should I start looking for libraries/methods to implement this encryption?
