  • Robust and easy to implement serial bus (automotive application)

    - by JcMaco
    What serial communication bus would you use in a automotive embedded system if your main selection criteria were: * Electrically robust * Slow speed (32 kb/s) * Easy to program * Easy to interface with microcontrollers It won't be transferring much data, but it will need to be transferred periodically at high speed (100 - 500 Hz). I find that RS-232 is just not reliable enough if you have noise in your ground line. CAN-bus seems interesting, but I have no experience with it. We are currently interested in a combination of AVR AT90CAN128 microcontrollers.

  • Can parser combination be made efficient?

    - by Jon Harrop
    Around 6 years ago, I benchmarked my own parser combinators in OCaml and found that they were ~5× slower than the parser generators on offer at the time. I recently revisited this subject and benchmarked Haskell's Parsec vs a simple hand-rolled precedence climbing parser written in F# and was surprised to find the F# to be 25× faster than the Haskell. Here's the Haskell code I used to read a large mathematical expression from file, parse and evaluate it: import Control.Applicative import Text.Parsec hiding ((<|>)) expr = chainl1 term ((+) <$ char '+' <|> (-) <$ char '-') term = chainl1 fact ((*) <$ char '*' <|> div <$ char '/') fact = read <$> many1 digit <|> char '(' *> expr <* char ')' eval :: String -> Int eval = either (error . show) id . parse expr "" . filter (/= ' ') main :: IO () main = do file <- readFile "expr" putStr $ show $ eval file putStr "\n" and here's my self-contained precedence climbing parser in F#: let rec (|Expr|) (P(f, xs)) = Expr(loop (' ', f, xs)) and shift oop f op (P(g, xs)) = let h, xs = loop (op, g, xs) loop (oop, f h, xs) and loop = function | ' ' as oop, f, ('+' | '-' as op)::P(g, xs) | (' ' | '+' | '-' as oop), f, ('*' | '/' as op)::P(g, xs) | oop, f, ('^' as op)::P(g, xs) -> let h, xs = loop (op, g, xs) let op = match op with | '+' -> (+) | '-' -> (-) | '*' -> (*) | '/' -> (/) | '^' -> pown loop (oop, op f h, xs) | _, f, xs -> f, xs and (|P|) = function | '-'::P(f, xs) -> let f, xs = loop ('~', f, xs) P(-f, xs) | '('::Expr(f, ')'::xs) -> P(f, xs) | c::xs when '0' <= c && c <= '9' -> P(int(string c), xs) My impression is that even state-of-the-art parser combinators waste a lot of time back tracking. Is that correct? If so, is it possible to write parser combinators that generate state machines to obtain competitive performance or is it necessary to use code generation?

  • Android browse SQLite database on phone

    - by Chris
    How can I browse the SQLite database that I am creating in my app on my Android myTouch phone? When I log in through adb shell, sqlite3 gives me a permission denied. Is there another way to check if my database and tables are actually being created, and if rows are being inserted? I am not able to use the emulator, since it doesn't play videos etc. very well that is the main feature of my app, so I can only test on phone. Thanks Chris

  • Any tool(s) for knowing the layout (segments) of running process in Windows?

    - by claws
    I've always been curious about How exactly the process looks in memory? What are the different segments(parts) in it? How exactly will be the program (on the disk) & process (in the memory) are related? My previous question: http://stackoverflow.com/questions/1966920/more-info-on-memory-layout-of-an-executable-program-process In my quest, I finally found a answer. I found this excellent article that cleared most of my queries: http://www.linuxforums.org/articles/understanding-elf-using-readelf-and-objdump_125.html In the above article, author shows how to get different segments of the process (LINUX) & he compares it with its corresponding ELF file. I'm quoting this section here: Courious to see the real layout of process segment? We can use /proc//maps file to reveal it. is the PID of the process we want to observe. Before we move on, we have a small problem here. Our test program runs so fast that it ends before we can even dump the related /proc entry. I use gdb to solve this. You can use another trick such as inserting sleep() before it calls return(). In a console (or a terminal emulator such as xterm) do: $ gdb test (gdb) b main Breakpoint 1 at 0x8048376 (gdb) r Breakpoint 1, 0x08048376 in main () Hold right here, open another console and find out the PID of program "test". If you want the quick way, type: $ cat /proc/`pgrep test`/maps You will see an output like below (you might get different output): [1] 0039d000-003b2000 r-xp 00000000 16:41 1080084 /lib/ld-2.3.3.so [2] 003b2000-003b3000 r--p 00014000 16:41 1080084 /lib/ld-2.3.3.so [3] 003b3000-003b4000 rw-p 00015000 16:41 1080084 /lib/ld-2.3.3.so [4] 003b6000-004cb000 r-xp 00000000 16:41 1080085 /lib/tls/libc-2.3.3.so [5] 004cb000-004cd000 r--p 00115000 16:41 1080085 /lib/tls/libc-2.3.3.so [6] 004cd000-004cf000 rw-p 00117000 16:41 1080085 /lib/tls/libc-2.3.3.so [7] 004cf000-004d1000 rw-p 004cf000 00:00 0 [8] 08048000-08049000 r-xp 00000000 16:06 66970 /tmp/test [9] 08049000-0804a000 rw-p 00000000 16:06 66970 /tmp/test [10] b7fec000-b7fed000 rw-p b7fec000 00:00 0 [11] bffeb000-c0000000 rw-p bffeb000 00:00 0 [12] ffffe000-fffff000 ---p 00000000 00:00 0 Note: I add number on each line as reference. Back to gdb, type: (gdb) q So, in total, we see 12 segment (also known as Virtual Memory Area--VMA). But I want to know about Windows Process & PE file format. Any tool(s) for getting the layout (segments) of running process in Windows? Any other good resources for learning more on this subject? EDIT: Are there any good articles which shows the mapping between PE file sections & VA segments?

  • Achieving a properly aligned sidebar in a DIV layout

    - by Pieter
    I'm experimenting with DIVs to align my page's contents: http://labs.pieterdedecker.be/test/test.htm As you can see, there's something wrong with the sidebar. I got the sidebar DIV to be aligned to the right of the page by doing float: right, but when the text in the sidebar stops the main area takes over the width that should be used by the sidebar. How do I fix this?

  • Stop execution of python script when parent Bash shell script is killed

    - by jrdioko
    I'm working on a Bash shell script that runs several Python scripts like so: cd ${SCRIPT_PATH} python -u ${SCRIPT_NAME} ${SCRIPT_ARGS} >> $JOBLOG 2>&1 At one point, I killed the shell script (using kill PID), but the Python script continued running, even after the script terminated. I thought these would die as soon as the main script died. What am I misunderstanding about Bash scripting, and what can I do to get the functionality I'm looking for? Thanks in advance!

  • how to debug "deep" crashes in Android?

    - by eerok512
    Hi All, I've been trying to debug an android crash that is occurring without a Java Stack Trace... Java Stack Trace bugs are very easy for me to fix... but this bug I'm getting seems to be crashing inside the "NDK" or whatever it is the deep internals of Android are called... I've made no modifications to the NDK btw... I just dunno what else to call that layer hehe. Anyway I'm mainly looking for advice on deep-debug methods, rather than help with this specific problem... because I doubt I can post all the source code involved... so really I just need to know how to set breakpoints at the deep layers or whatever other methods there are to trace deep-crashes to their source... so I will briefly describe the bug and then post a LogCat. I have an app with 7 Activities Activity_INTRO Activity_EULA Activity_MAIN Activity_Contact Activity_News Activity_Library Activity_More INTRO is the initiating one... it fades in some company logos... after displaying them for a set time it jumps to the EULA activity... after the user accepts the EULA, it jumps to MAIN... MAIN then creates a TabHost and populates it with the 4 remaining activities now heres the thing... when I click on say, the More tab of the TabHost, the app pauses for a few seconds and then hard-crashes... no java stack trace, but an actual ASM level trace with the registers and IP and stack... the same thing occurs no matter which tab I select, Contact, News, Library, More... all of them crash with the same hard-crash if however I set the manifest to start the app at Activity_MAIN, bypassing the INTRO and EULA, then these crashes do not occur... so something is lingering from those opening activities that is somehow hosing the TabHost'ed Activities... and I'm wondering what the hell that could be... because I'm using finish() on those activites when they need to jump... in fact here is how I'm doing it let me know if you see any bugs: when jumping from INTRO to EULA I do: //Display the EULA Intent newIntent = new Intent (avi, Activity_EULA.class); startActivity (newIntent); finish(); and EULA to MAIN: Intent newIntent = new Intent (this, Activity_Main.class); startActivity (newIntent); finish(); anyway, here is the hard crash log... please let me know if there is some way I can reverse engineer either /system/lib/libcutils.so or /system/lib/libandroid_runtime.so, because I think the crash is happening in one of them... i think its happening in the libandroid_runtime in fact.... anyway on to the log: 12-25 00:56:07.322: INFO/DEBUG(551): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** 12-25 00:56:07.332: INFO/DEBUG(551): Build fingerprint: 'generic/sdk/generic/:1.5/CUPCAKE/150240:eng/test-keys' 12-25 00:56:07.362: INFO/DEBUG(551): pid: 722, tid: 723 >>> com.killerapps.chokes <<< 12-25 00:56:07.362: INFO/DEBUG(551): signal 11 (SIGSEGV), fault addr 00000004 12-25 00:56:07.362: INFO/DEBUG(551): r0 00000004 r1 40021800 r2 00000004 r3 ad3296c5 12-25 00:56:07.372: INFO/DEBUG(551): r4 00000000 r5 00000000 r6 ad342da5 r7 41039fb8 12-25 00:56:07.372: INFO/DEBUG(551): r8 100ffcb0 r9 41039fb0 10 41e014a0 fp 00001071 12-25 00:56:07.382: INFO/DEBUG(551): ip ad35b874 sp 100ffc98 lr ad3296cf pc afb045a8 cpsr 00000010 12-25 00:56:07.552: INFO/DEBUG(551): #00 pc 000045a8 /system/lib/libcutils.so 12-25 00:56:07.572: INFO/DEBUG(551): #01 lr ad3296cf /system/lib/libandroid_runtime.so 12-25 00:56:07.582: INFO/DEBUG(551): stack: 12-25 00:56:07.582: INFO/DEBUG(551): 100ffc58 00000000 12-25 00:56:07.592: INFO/DEBUG(551): 100ffc5c 001c5278 [heap] 12-25 00:56:07.602: INFO/DEBUG(551): 100ffc60 000000da 12-25 00:56:07.602: INFO/DEBUG(551): 100ffc64 0016c778 [heap] 12-25 00:56:07.602: INFO/DEBUG(551): 100ffc68 100ffcc8 12-25 00:56:07.602: INFO/DEBUG(551): 100ffc6c 001c5278 [heap] 12-25 00:56:07.612: INFO/DEBUG(551): 100ffc70 427d1ac0 12-25 00:56:07.612: INFO/DEBUG(551): 100ffc74 000000c1 12-25 00:56:07.612: INFO/DEBUG(551): 100ffc78 40021800 12-25 00:56:07.612: INFO/DEBUG(551): 100ffc7c 000000c2 12-25 00:56:07.612: INFO/DEBUG(551): 100ffc80 00000000 12-25 00:56:07.612: INFO/DEBUG(551): 100ffc84 00000000 12-25 00:56:07.622: INFO/DEBUG(551): 100ffc88 00000000 12-25 00:56:07.622: INFO/DEBUG(551): 100ffc8c 00000000 12-25 00:56:07.622: INFO/DEBUG(551): 100ffc90 df002777 12-25 00:56:07.632: INFO/DEBUG(551): 100ffc94 e3a070ad 12-25 00:56:07.632: INFO/DEBUG(551): #00 100ffc98 00000000 12-25 00:56:07.632: INFO/DEBUG(551): 100ffc9c ad3296cf /system/lib/libandroid_runtime.so 12-25 00:56:07.632: INFO/DEBUG(551): 100ffca0 100ffcd0 12-25 00:56:07.642: INFO/DEBUG(551): 100ffca4 ad342db5 /system/lib/libandroid_runtime.so 12-25 00:56:07.642: INFO/DEBUG(551): 100ffca8 410a79d0 12-25 00:56:07.642: INFO/DEBUG(551): 100ffcac ad00e3b8 /system/lib/libdvm.so 12-25 00:56:07.652: INFO/DEBUG(551): 100ffcb0 410a79d0 12-25 00:56:07.652: INFO/DEBUG(551): 100ffcb4 0016bac0 [heap] 12-25 00:56:07.662: INFO/DEBUG(551): 100ffcb8 ad342da5 /system/lib/libandroid_runtime.so 12-25 00:56:07.662: INFO/DEBUG(551): 100ffcbc 40021800 12-25 00:56:07.662: INFO/DEBUG(551): 100ffcc0 410a79d0 12-25 00:56:07.662: INFO/DEBUG(551): 100ffcc4 afe39dd0 12-25 00:56:07.662: INFO/DEBUG(551): 100ffcc8 100ffcd0 12-25 00:56:07.662: INFO/DEBUG(551): 100ffccc ad040a8d /system/lib/libdvm.so 12-25 00:56:07.672: INFO/DEBUG(551): 100ffcd0 41039fb0 12-25 00:56:07.672: INFO/DEBUG(551): 100ffcd4 420000f8 12-25 00:56:07.672: INFO/DEBUG(551): 100ffcd8 ad342da5 /system/lib/libandroid_runtime.so 12-25 00:56:07.672: INFO/DEBUG(551): 100ffcdc 100ffd48 12-25 00:56:07.852: DEBUG/dalvikvm(722): GC freed 367 objects / 15144 bytes in 210ms 12-25 00:56:08.081: DEBUG/InetAddress(722): www.akillerapp.com: 74.86.47.202 (family 2, proto 6) 12-25 00:56:08.242: DEBUG/dalvikvm(722): GC freed 62 objects / 2328 bytes in 122ms 12-25 00:56:08.771: DEBUG/dalvikvm(722): GC freed 245 objects / 11744 bytes in 179ms 12-25 00:56:09.131: INFO/ActivityManager(577): Process com.killerapps.chokes (pid 722) has died. 12-25 00:56:09.171: INFO/WindowManager(577): WIN DEATH: Window{43719320 com.killerapps.chokes/com.killerapps.chokes.Activity_Main paused=false} 12-25 00:56:09.251: INFO/DEBUG(551): debuggerd committing suicide to free the zombie! 12-25 00:56:09.291: DEBUG/Zygote(553): Process 722 terminated by signal (11) 12-25 00:56:09.311: INFO/DEBUG(781): debuggerd: Jun 30 2009 17:00:51 12-25 00:56:09.331: WARN/InputManagerService(577): Got RemoteException sending setActive(false) notification to pid 722 uid 10020

I'd like to find a way to combine multiple small changesets into a single changeset, for merging the changes to child repositories. E.g in the default/main repo there are changesets something like: 12839: Fooed the bar 12838: Fixed blonking 12837: Trumped slamdunks ... 323: Started development for thingamajiks and I would like this to look like (in the child repos): 323: Added thingamajik functionality

    Hey, Can someone suggest me how to implement a pop-up window in Java Swing. I want the pop-up window to be a modal window (user cannot return to the main window when the pop-up is open). I tried doing it using JDialog but it allows only one widget for user input to be in it whereas I need multiple widgets. I may be wrong here but this is what I was able to do. Appreciate your help.

    Hi, I am having a problem after opening the notepad once I click the button "btnSearch". The idea is that once I clicked the button 'btnSearch', the textbox 'txtSearch' should be 'focused' even after a process was initiated/opened outside the main window. Here's my code: private void btnSearch_Click(object sender, RoutedEventArgs e) { System.Diagnostics.Process.Start("notepad"); txtSearch.Focus(); // not working } Any suggestions?

  • How do I integrate a new MVC C# Project with an existing Web Forms VB.NET Web Application Project?

    - by Jordan Rieger
    We have a corporate website with a large amount of dynamic business application pages (e.g. Shopping Cart, Helpdesk, Product/Service management, Reporting, etc.) The site was built as an ASP.Net Web Application Project (WAP). Our systems have evolved over the years to use .NET 4.5 and various custom business logic DLLs (written in a mix of C# and VB.NET). However, the site itself is still using VB.NET Web Forms. We now have done a few side projects in MVC 4 using Razor/C#, and we want to use this framework for new pages on the main corporate site going forward. What would be the easiest way to achieve this? I found this nice list of steps to integrate MVC 4 into an existing Web Forms app. The problem is that because our existing app is a VB.NET WAP, it compiles into a single DLL, and .NET allows only one language per DLL. The site is way too big for us to contemplate converting it to C# all at once (yes, I've looked at the conversion tools, and they're good, but even 99% accuracy would leave us a huge amount of cleanup work.) I thought about converting the existing WAP into a Web Site Project (WSP) which does allow mixing languages and then following the steps above, but after a few pages of Google results, I couldn't find any steps for converting a WAP to WSP. (Plenty of sites offer the reverse steps: converting a WSP to a WAP.) Another idea I had was to create a completely separate MVC project, and then somehow squish them together into the same folder structure, where they would share the bin folder but compile to separate DLL's. I have no idea if this is possible, because certain files would collide (e.g. Global.asax, web.config, etc.) Finally, I can imagine a compromise solution where we keep all the MVC stuff in its own separate application under a subfolder of the main solution. We already use our own custom session state solution, so it wouldn't be difficult to pass data between the old site to the new pages. Which of the ideas above do you think makes the most sense for us? Is there another solution that I'm missing?

  • Learning MVC - Maintaining model state

    - by GenericTypeTea
    First of all, I'm very new to MVC. Bought the books, but not got the T-Shirt yet. I've put together my first little application, but I'm looking at the way I'm maintaining my model and I don't think it looks right. My form contains the following: <% using (Html.BeginForm("Reconfigured", null, FormMethod.Post, new { id = "configurationForm" })) { %> <%= Html.DropDownList("selectedCompany", new SelectList(Model.Companies, Model.SelectedCompany), new { onchange = "$('#configurationForm').submit()" })%> <%= Html.DropDownList("selectedDepartment", new SelectList(Model.Departments, Model.SelectedDepartment), new { onchange = "$('#configurationForm').submit()" })%> <%=Html.TextArea("comment", Model.Comment) %> <%} %> My controller has the following: public ActionResult Index(string company, string department, string comment) { TestModel form = new TestModel(); form.Departments = _someRepository.GetList(); form.Companies = _someRepository.GetList(); form.Comment = comment; form.SelectedCompany = company; form.SelectedDepartment = department; return View(form); } [HttpPost] public ActionResult Reconfigured(string selectedCompany, string selectedDepartment, string comment) { return RedirectToAction("Index", new { company = selectedCompany, department = selectedDepartment, comment = comment}); } And finally, this is my route: routes.MapRoute( "Default", "{controller}/{company}/{department}", new { controller = "CompanyController", action = "Index", company="", department="" } ); Now, every time I change DropDownList value, all my values are maintained. I end up with a URL like the following after the Reconfigure action is called: http://localhost/Main/Index/Company/Sales?comment=Foo%20Bar Ideally I'd like the URL to remain as: http://localhost/Main/Index My routing object is probably wrong. This can't be the right way? It seems totally wrong to me as for each extra field I add, I have to add the property into the Index() method? I had a look at this answer where the form is passed through TempData. This is obviously an improvement, but it's not strongly typed? Is there a way to do something similar but have it strongly typed? This may be a simple-enough question, but the curse of 10 years of WinForms/WebForms makes this MVC malarky hard to get your head 'round.
