  • How should I architect a personal schedule manager that runs 24/7?

    - by Crawford Comeaux
    I've developed an ADHD management system for myself that's attempting to change multiple habits at once. I know this is counter to conventional wisdom, but I've tried the conventional for years & am now trying it my way. (just wanted to say that to try and prevent it from distracting people from the actual question) Anyway, I'd like to write something to run on a remote server that monitors me, helps me build/avoid certain habits, etc. What this amounts to is a system that: runs 24/7 may have multiple independent tasks to run at once may have tasks that require other tasks to run first lets tasks be scheduled by specific time, recurrence (ie. "run every 5 mins"), or interval (ie. "run from 2pm to 3pm") My first naive attempt at this was just a single PHP script scheduled to run every minute by cron (language was chosen in order to use a certain library, but no longer necessary). The logic behind when to run this or that portion of code got hairy pretty quick. So my question is how should I approach this from here? I'm not tied to any one language, though I'm partial to python/javascript. Thoughts: Could be done as a set of scripts that include a scheduling mechanism with one script per bit of logic...but the idea just feels wrong to me. Building it as a daemon could be helpful, but still unsure what to do about dozens of if-else statements for detecting the current time

  • Windows Physical Direct Memory Mapping

    - by chrisjleaf
    I'm a bit disappointed there is almost no discussion of this no matter where I look so I guess I'll have to ask. I'm writing a cross platform memory bench marking application which requires direct physical address mapping rather than virtual addressing. EDIT The solution would look something like the Linux/Unix system calls: int fd = open("/dev/mem", O_RDONLY); mmap(NULL, len, PROT_READ, MAP_SHARED, fd, PHYSICAL_ADDRESS_OFFSET); which will require the kernel to either give you a virtual page mapping to the desired physical address or return that it failed. This does require supervisor privileges but that is ok. I have seen a lot of information about shared memory and memory mapped files but all of these reside on disc and are thus not really useful when I'm trying to make a system dependent read. It is very similar to writing an IO driver although I do no need write permissions to the physical address. This site gives an example of how to do it on a driver level using the Windows Driver Kit: NT Insider: Sharing Memory between drivers and applications This solution would probably require Visual Studio which currently I do not have access to. (I have downloaded the WDK api but it complained about my use of GCC for Windows). I'm traditionally a Linux programmer so I'm hoping there might be something really simple I'm missing. Thanks in advance if you know something I don't!

  • How can I bulk rename files in a RAR or ZIP archive on the mac?

    - by Chris R
    I have a set of archive files -- both zip and rar formats -- inside of which I need to rename some files. Specifically, I want to do something like this: for each archive file in a directory for each file in the archive if the file name matches the regular expression /(.* - [0-9]{2})([0-9]{2} - .)*/ rename the file as \1-\2 The trick isn't so much in the generation of the new name; I can do that with either bash or sed or anything else. It's the set of commands to manipulate the files in the archives using rar/unrar or unzip/zip (If it makes a difference, I'm re-formatting some CBR/CBZ files to get the double-page spreads to come up in the right order in SimpleComic -- it interprets page 0203 as page 203, which makes the story a bit hard to follow)

  • Missing characters when printing in linux

    - by jarvisschultz
    I have a pdf that I was printing recently, and on the final printout there is a single character that doesn't print. It is the greek letter phi, and the pdf was built with pdflatex. The phi shows up in every pdf reader I have tried, and if I convert to a ps using pdftops before printing that solves the problem. Also, I sent the pdf to a buddy who has a very similar machine (Ubuntu 12.04 64 bit, with the same printer drivers), and he was able to print it (to the same printer) and the character showed up. Clearly I have a workaround, but I'm more curious as to where I should be looking to figure out what is causing this bug? What is the printing "toolchain", and where could it be going wrong?

  • Problem with installing Nvidia display drivers on Ubuntu 13.10

    - by Pascal
    Hello everyone and thank you for taking a look at this topic! I'm currently trying out Ubuntu 13.10 but I keep hitting a wall when it comes to installing a driver. I've tried: sudo apt-get install nvidia-current This resulted in a un-bootable system. The screen just stayed black and the cursor displayed as an 'X'. After that I did had to re-install Ubuntu. The computer I'm using is an Acer-Aspire-V3 with a build in Nvidia geforce GT 630M and also with a Intel HD graphics chip-set (not sure if chip-set is the right word here). "lspci | grep VGA" output: pascal@pascal-Aspire-V3-571G:~$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev a1) I've searched a bit here and there and found out that it would be wise to mention that this laptop is using (or so I think) Nvidia Optimus, not sure if it will add anything to the subject but at least I'll mention it just to be sure. Now to the questions: Q1 How is this caused and how can I fix it? Q2 What additional information could I provide to help you help me?

  • How to control an actor movement in UDK

    - by Mikalichov
    This might be very basic, but I couldn't find something relevant to what I need (see below). I am working on a very basic thing: a 3D environment with some buildings, and actors walking inside it. It looks like following: I mainly want to manage to have one actor standing around, idling, and another walking around the area. Right now, this is done through matinee + skeletal mesh groups, and forcing a looped animation on the actors: But I realize this is super caveman-level. So I've build an AnimTree, linking the idling and directional animations to the corresponding nodes. But then, I'm stuck. I added the AnimTree in the actors properties, but nothing happens. I've tried MoveToActor, but no success - is there a thing to set to allow an actor to move? Also, I place the actors on the map manually (they are supposed to be unique), should I spawn them instead? Every tutorial I find explains how to use an AnimTree for the player character, which is not what I want. I need a way to move the actors. I tried to look for AI tutorials, but only found UT3 bots-modifications, which is not what I need either. Since I have so much trouble finding how to do this through Kismet, I'm starting to suspect this has to be done through scripting/coding, but I would like to be sure there is no way to do it through Kismet before going that route. Every bit of answer about how to tell an actor something along the lines of "go in that direction as much as you can, then when you hit a wall turn 45° and continue" would be awesome. I'll be happy to move/edit the question if there is any problem with it

  • easiest way to (download and) convert HTML-structures into EPUB?

    - by gojira
    How would one (download and) convert HTML-structures into EPUB (or any other format suitable for the Sony PRS-505 reader)? My question is not how to convert a single HTML file into an EPUB file, as this is easy; what I mean is, I have some books I want to read on my Sony PRS-505 and these books are most often online in HTML format but withmany interlinked pages and there is one page with the list of contents, like this example http://www.edge.org/documents/ThirdCulture/d-Contents.html ... or sometimes it's a little bit more complicated as the list of contents only lists the chapters, and inside the chapters there are links to sub-chapters, like in this example: http:SLASHSLASHwww.hyw.com/Books/WargamesHandbook/Contents.htm (I can only post 1 hyperlink now b/c of user restriction, so this is why there is SLASHSLASH instead of //) I want to convert these examples and several others, with correct chapters, images and some acceptable formatting etc, so basically I want to make a proper ebook out of the HTML-tree. What is the easiest way?

    Hi lads, I'm building some kind of webapp, and currently the whole thing runs on my machine. I was combing down my logs, and found several "strange" log entries that made me a bit paranoid.

  • Windows XP not able to boot after loading isapnp.sys driver

    - by pragadheesh
    Hi When i power on my DELL Latitude E6400 laptop running on Windows XP SP3, i get a black screen and hangs after that. So I tried to boot through safe mode which hangs after loading the driver isapnp.sys. Doing a bit of googling i found out Windows XP not booting up including safe mode So I loaded my XP boot cd and tried Recovery Console. In the Recovery console, doing "dir" gives the error "an error occurred during directory enumeration". Then i tried chkdsk /p /r which gave "the volume appears to contain one or more unrecoverable problems" How can i fix these please. Thanks in advance.

  • NetBeans has broken interface with OpenJDK

    - by Krzysztof Stanislawek
    Sorry for English. Usually (say, at 4/5 of times), when I start NetBeans, interface is partially broken. For example, menu items are appearing and at once disappearing after click; some parts of editor are also blocked for cursor actions. Another issue is broken Options window - I can show it only once for NetBeans execution. There are more similar issues. $ java -version java version "1.7.0_55" OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1ubuntu1~0.13.10.1) OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode) Version of NetBeans is 7.0.1. Linux version is Mint 16. I use Mate. I had the same issue at other computer, at the same operating system. I know that installing Sun version of Java could help, but I also know that there shouldn't be such issue with OpenJDK. Also, I had other problem with NetBeans and Sun Java 8 - NetBeans suddenly crashed before he fully started, so I want to stick with OpenJDK. What causes my problem? Should I use other version of NetBeans/OpenJDK?

  • Mass editing videos on Ubuntu?

    - by rick
    Hi, I'm trying to add a watermark and a credits image to all of my old videos. I downloaded them off YouTube so they are all flv (H.264?). Is there some software that will allow me do simple edits in batches? I know a little bit of Python and tried looking at some of the library but they all seem like overkill (and way above my head). So is there a solution besides getting some software and going through all my videos and doing it manually? They are all mostly the same length, but it would be nice to specify a relative position for my credits. e.g. show a static image for 10 seconds when the video is at 95%

  • Outlook 2010 - HTML Images not downloaded - at all - by default

    - by Scott Lock
    Maybe it's just me but I found this "Security Feature" of Office 2010 a bit annyoing out of the box.  Outlook does not download any pictures by default for HTML emails.  Now this is nothing new, but what is different is that Outlook 2010 has added another layer of security around the pictures.  You now have the option to finely tune when things are downloaded.  The side affect is that nothing is downloaded at all.  And when I would click on "Download Images" on an email, it still would not show the images.  I found that I had to explicitly tell Outlook to download HTML images and then restart Windows.  It did not work if I simply restarted Office.  Again, maybe this was just me.  Here's what you need to do in Outlook 2010 to enable images for HTML: Click on the new "File" tab Click on "Options" Click on "Trust Center" Clicn on "Trust Center Settings" Uncheck the "Don't download pictures automatically in HTML e-mail messages or RSS items" check box Click the "Okay" button Exit Outlook 2010 Again, for me I had to restart Windows (Windows 7 64bit, Office 2010 64bit) to get this to "take affect".

  • Raspberry Pi, Time Capsule Progress

    - by Richard Jones
    So by way of an update. I thought all was good with my Raspberry Pi, Debian and Netatalk Apple Time Capsule Clone. However something very strange going on. Although I could backup my Mac's + PC's fine to Raspberry Pi with external USB HD; strangely with RPI running, I couldn't use AirPlay. I found myself unable to play anything from Mac to Apple TV. So after lots of trying to make this work, I about turned and finally went out and got myself a 2TB Apple Time Capsule. More cash than I would want to spend on anything like this, but Apple you got me. I would like to offer a top tip, which maybe goes a small way to justifying silly expenditure... You can easily add a USB HD to any Time Capsule. I've just added a 3 TB external USB HD, giving me a 5 TB of total backup grunt. 3 TB External USB HD, was peanuts by comparison to Apple kit. So all working, its all solid as you'd expect.Apple 2, maybe me .5. But strong, solid backups now happening, without hassle (but a bit of a credit card bill to follow)

  • users unable to add registry keys to HKCU

    - by Eds
    I may not have this 100% correct so need some clarification. Are normal users on a 2003 terminal server allowed to add registry keys the their own HKCU section in the registry, or are they only allowed to edit existing ones? The reason I ask is that we have 3 keys that we need to add for each user on login. I thought it would be as simple as having a straightforward batchscript run that silently adds the keys for the user. Here is what I used: regedit.exe "C:\Documents and Settings\All Users\Desktop\example.reg" When the user runs this batch scipt, they see nothing as you would expect, but the keys are not added. If I simply run the .reg file as the user, it asks if I want to add the key, but then has an error saying there was an error accessing the registry. Do I need something a bit more complex to accomplish this task. Many Thanks Eds EDIT: Contents of .reg file Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Policies\Microsoft\office\14.0\outlook\Security] "PromptSimpleMAPINameResolve"=dword:00000002 "PromptSimpleMAPIOpenMessage"=dword:00000002 "PromptSimpleMAPISend"=dword:00000002

  • Making the most of dual channel DDR2: how do I arrange the sticks?

    - by andrz_001
    I've searched online, but I can't find anything definitive that will put me at ease. I turn to superuser. This is how I have the RAM sticks arranged now: To make the most of the RAM and the dual channel capability, it occurred to me that perhaps I have the sticks arranged incorrectly. Should I move the stick in the DDR2_2 slot one over--to the adjacent, red slot? I appreciate any suggestions. (BTW, can something in BIOS tell me whether I'm running at "optimal" memory speeds??) edit: I'm running Windows XP SP3, 32-bit. Thanks.

  • Windows 2008 additional disk going offline with reboots on Amazon EC2

    - by Ernest Mueller
    OK, so I took the stock Windows 2008 64-bit Amazon AMI and wanted to add a D: drive for page file space and crash dumps. I launched the instance with a second EBS volume attached as xvdf and went into Disk Management set it online, and added the page file and crash dump settings and all that works. But when I reboot, the box comes back up with that second drive as "Offline." How do I get that disk to automatically come online on reboot (or most notably, when I turn this into an AMI and launch more instances off it - I've tried that too and same deal with the D:).

  • Don't miss Virtual Developer Day - All about ADF next week

    - by Shay Shmeltzer
    In case you haven't heard we are holding a free online virtual developer day next week - July 10th that you should attend - even if you think you already know ADF. First the registration link - http://bit.ly/fusiondev. While one of the tracks is aimed at developer who are relatively new to ADF - and cover ADF Faces, ADF Controller and a comparison of productivity with Forms and other tools - the two other tracks have great content on some topics that you might not be familiar with even if you already work with ADF. This include sessions about the upcoming ADF Mobile, The new ADF support in Eclipse and information about Application Life Cycle Management with ADF and JDeveloper. As well as sessions that will open your mind to the areas where ADF integrates with other Fusion Middleware Solutions such as ADF integration with BI, WebCenter and SOA. Most of the sessions are quite heavy on demos and you'll get a chance to interact with the presenters and ask questions during the live event. You should register even if you can't attend the live event - this way you'll get an email pointing you to the recorded sessions for on demand viewing. See you next week.

  • Logging upload attempt with proftpd

    - by Amit Sonnenschein
    I have a logging server that i use with external hardware, the idea is that a special hardware is uploading logs about it's operation every few hours and from the server i can do whatever i need to do with the information, the old server was getting a bit too old and i've moved to a new one, i've install lamp,proftpd and ssh (just the same as i had on the old server). now for some reason the logs are not being uploaded and i don't know why. the hardware uses a direct ftp access - i've the proftpd.log and saw that the connection is not being rejected (just to make sure i didn't make a mistake with the user/pass) my problem is that for some reason the upload itself is failing... it might be due to wrong path (as it's hard coded in the hardware) but i can't really know as proftpd wont give me any details.. i've tried to change the loglevel to "debug" thinking it would give me more information but i don't see any change... is there any other way i can make sure proftpd logs EVERTHING ?

  • Better way to go up/down slope based on yaw?

    - by CyanPrime
    Alright, so I got a bit of movement code and I'm thinking I'm going to need to manually input when to go up/down a slope. All I got to work with is the slope's normal, and vector, and My current and previous position, and my yaw. Is there a better way to rotate whether I go up or down the slope based on my yaw? Vector3f move = new Vector3f(0,0,0); move.x = (float)-Math.toDegrees(Math.cos(Math.toRadians(yaw))); move.z = (float)-Math.toDegrees(Math.sin(Math.toRadians(yaw))); move.normalise(); if(move.z < 0 && slopeNormal.z > 0 || move.z > 0 && slopeNormal.z < 0){ if(move.x < 0 && slopeNormal.x > 0 || move.x > 0 && slopeNormal.x < 0){ move.y += slopeVec.y; } } if(move.z > 0 && slopeNormal.z > 0 || move.z < 0 && slopeNormal.z < 0){ if(move.x > 0 && slopeNormal.x > 0 || move.x < 0 && slopeNormal.x < 0){ move.y -= slopeVec.y; } } move.scale(movementSpeed * delta); Vector3f.add(pos, move, pos);

  • Horde on Debian: packages or upstream?

    - by fhd
    I'm currently using the Horde projects IMP, DIMP, MIMP, Ingo, Kronolith, Mnemo, Nag, Turba and Sork. I ignored the (rather outdated) Debian packages and installed the upstream versions. A few years later, my Horde installation is a bit outdated and I consider updating each project and each version individually a pain. The Debian stable packages are as outdated as ever, but squeeze will deliver reasonably current versions, so I'm considering switching to the Debian packages as soon as squeeze is released. What would you recommend for software packages like Horde? Using the upstream versions and manually updating or using the distribution's packages?

  • Strange Exchange 2010 Mailbox issues

    - by jmreicha
    A little bit of information on my environment. I have 2 Exchange 2010 mailbox servers setup in a DAG, connected to a VNX SAN via fiber for the mailbox database disks. One of the servers seems to be working fine as it isn't throwing any similar errors but the other has been receiving strange errors in Event Viewer. I haven't been able to find a pattern to when these happen and I'm not really sure what I should be looking at to troubleshoot this. At this point I am wondering if the issue resides on the SAN or if this is because of an improper shutdown or something else on the Exchange side of things? Here are a few of the errors if that helps:

  • Separate collision mesh model?

    - by Menno Gouw
    I want to have another go at 3D within XNA. What I have seen from some other games that they just have a separate very low poly model "cage" around the environment model. However I can not find any reference to this. I have not that much experience with XNA 3D either. Is it possible to have this cage within each of my environmental models already? Lets just say I call the mesh within the .FBX wall and col_wall. How would I call to these different meshes within XNA? The player would just have a tight collision cube around. To make it a bit more efficient I will be making divide the map up by cubes and only calculate collision if the player is in it. Question two: I can't find anywhere to do cube vs mesh collision. Is there a method for this? Or perhaps it is possible to build my collision cage out of cubes in the 3D app and on loading of the models in XNA replace them directly by cubes? So I could just do box to box collision which should be very cheap and still give the player the ability to move over ledges on the static models.
