  • Control cell reference increment when dragging a forumula in Libre Office Calc (3.5)

    - by Chuck
    Using Libre Office Calc (3.5) and have a question. When copying a formula that references cells into multiple empty cells the default is to increment each cell reference by one column or row, depending on the direction that the formula is being drug. A formula '= 1 + A1' drug horizontally changes to '= 1 + B1' when pulled one cell to right and '=1 + A2' when pulled one cell down. Is there a way to control increase the increment of the referenced cell? Is is possible to have a formula '= 1 + A1' that effectively changes to '= 1 + A3' when drug down one cell, '= 1 + A5' when drug down two cells, etc? If it matters, I am trying to take a constantly updating master list of data that is organized by dates (Wednesdays and Saturdays) and create separate spread sheets for each day of the week that can be updated by only pulling down the formula into the next cell. My attempts at using the 'lookup' function, 'offset' function, and creating a sort column in Libre Office Calc are thwarted by my inability to figure out how to get around the single step increment when pulling a formula down into the next cell. Thanks

  • Why do we still have to use drive letters to identify file systems?

    - by Charles E. Grant
    A friend has run into a problem where they installed Windows 7 from an external drive, and the internal boot drive is now assigned to H:. Theoretically this shouldn't cause problems because there are programming interfaces for getting the drive letter for the system drive. In practice though, there are quite a few programs that assume that C: is the only possible location for the system directories, and they refuse to run with the system directories on H:. That's not Microsoft's fault, but it's a pain none-the-less. The general consensus seems to be that a re-install, setting the internal boot drive to C:, is the only way to avoid fix these problems. UNIX-like systems display all file systems in a single unified directory tree and mostly seem to avoid problems like this. Is it possible to configure a Windows system without reference to drive letters, or does the importance of backwards compatibility mean that Windows will be working with drive letters from now until doomsday?

  • Remote desktop to multiple windows machines on a LAN with dynamic IP

    - by kevyn
    Is it possible to use remote desktop to connect to multiple computers inside a network that has a dynamic IP address? I use a netgear WPN824 router which has dyndns onboard - but I currently use No-IP to control a single computer that I use most frequently. Every so often I need to get onto a couple of other computers in the network, but don't know how to go about this without logging onto one computer, and then starting another RDC session from that machine. What I would like to be able to do is connect to my router, and be able to see a list of connected devices, and then choose which to remote desktop onto. - I appreciate this probably is not be possible, but any other suggestions are welcome!

  • How can I deal with a difficult developer that is holding back the project? [migrated]

    - by ILovePaperTowels
    Our entire project is being held up because of one piece which is being handled by a single developer. When we did finally got the latest version of his code and started reviewing it, we found the code was horrendous! Its a relatively simply workflow, however the code is so complex that it's very difficult to step through and review/debug. The developer responsible has a hard time accepting any kind of criticism, and feels he is more knowledgeable than others members of the team. It's difficult to even talk to him about his development work because it turns into "I know what I'm talking about and you're just wrong!" type of conversation. A request has already been put in to replace this developer but management is not doing anything. This is probably because devs are in short supply where we are, and this is a corporation has a lot of office drama. I'm just one of the developers, not the project manager, however I really want to see this project succeed. What can I do in this sort of situation to try and keep the project on track?

  • Advice on reconciling discordant data

    - by Justin
    Let me support my question with a quick scenario. We're writing an app for family meal planning. We'll produce daily plans with a target calorie goal and meals to achieve it for our nuclear family. Our calorie goal will be calculated for each person from their attributes (gender, age, weight, activity level). The weight attribute is the simplest example here. When Dad (the fascist nerd who is inflicting this on his family) first uses the application he throws approximate values into it for Daughter. He thinks she is 5'2" (157 cm) and 125 lbs (56kg). The next day Mom sits down to generate the menu and looks back over what the bumbling Dad did, quietly fumes that he can never recall anything about the family, and says the value is really 118 lbs! This is the first introduction of the discord. It seems, in this scenario, Mom is probably more correct that Dad. Though both are only an approximation of the actual value. The next day the dear Daughter decides to use the program and sees her weight listed. With the vanity only a teenager could muster she changes the weight to 110 lbs. Later that day the Mom returns home from a doctor's visit the Daughter needed and decides that it would be a good idea to update her Daughter's weight in the program. Hooray, another value, this time 117 lbs. Now how do you reconcile these data points? Measurement error, confidence in parties, bias, and more all confound the data. In some idealized world we'd have a weight authority of some nature providing the one and only truth. How about in our world though? And the icing on the cake is that this single data point changes over time. How have you guys solved or managed this conflict?

  • HP Deskjet 3600: Offline and won't stop blinking and won't print.

    - by George Bailey
    Using Vista and an HP Deskjet 3600 on USB connection Normally when I unplug the printer, I open the printer queue and in the title bar it says "HP Deskjet 3600 - Use Printer Offline" then the offline message will go away and it will start printing. But for some reason, the bower button light is continually blinking. (this is the only light on the machine). The printer queue says "HP Deskjet 3600 - Offline" and when I unplug it it says "HP Deskjet 3600 - Offline - Use Printer Offline". I have tried unplugging it for a few hours, also tried turning it off for a few hours. Does anybody know what the single word Offline means? Does anybody know how I can clear out the memory in the Printer? (this is my guess as to what is causing the problem)

  • Does using VLANs in your network infrastructure cause an appreciable decrease in performance?

    - by Peter Grace
    This is something I've never considered before and wanted the opinions of the experts. We use VLANs day in and day out for various network tasks. My modus operandi is that in general, if something supports VLANs, that port is getting trunked because it just makes a ton of sense if there's even the slightest chance you need to do more than one thing on that single link. As I ponder this, though, I'm wondering whether there's a performance penalty involved with this line of thinking? Is the impact negligible?

  • IRC Services with failover support?

    - by insertjokehere
    I run a single server (call it 'server A') IRC 'network', and thank to the generosity of some friends, I have been given a second server ('server B') that I can run an IRCd on in order to provide redundancy in case server A crashes. This is fine, I can set up a round-robin DNS with the servers linked. The problem I have is what to do about services? Does anyone know of a way to get the services to 'fail over' in case of a server failure? Eg, Server A starts off running the services, but suddenly crashes. Server B detects this and starts its own copy of the services (ideally with the same configuration and data as the services on Server B) One solution that comes it mind is to write a bot that each server runs, that sit in a channel periodically checking if the bot from the other server is in the channel. If it is, then all is well. If not, then failover. I would prefer not to have to code this myself though We are currently using Unreal IRCd and Anope services on Linux

  • Looking for way to download all the free software I need to setup my PC all at once . . .

    - by Jim McKeeth
    I am in the middle of reinstalling Windows 7, and I would like to install all the software in as few steps as possible. I saw a web site recently that listed a lot of different Freeware and Opensource appliations. There was a checkmark next to each one so you could select the ones you want, and then they would all download in a single package to install at one time. The idea was for when you were setting up after a fresh install. It was for Windows and they were adding 64-bit applications.

  • windows - batch moving files to another folder/directory

    - by jdamae
    I am getting an error message to the effect of unable to move files to a single file. I am not trying to do this. What I am trying to do is move files from one folder to another folder (staging) and then deleting the original folder. If you can show me a better way to do this since I am not doing this correctly. Thank you. Here is my .cmd file: Y: move "Y:\ABC_files\*.js" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC_files\*.css" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC_files\*.png" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC_files\*.htm" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC_files\*.gif" "C:\Documents and Settings\user\Desktop\ABC_Stage\ABC_files\" move "Y:\ABC.htm "C:\Documents and Settings\user\Desktop\ABC_Stage\" rmdir "Y:\ABC_files" C:\"Program Files"\"App X"\App-IDE.exe -r ABC4.run

  • Why are my downloads up to ~1500KByte/sec only, when the ADSL connection locks at 13611Kbit/s?

    - by leladax
    No uploading is going on other than the overhead of downloading which appears to be not high for the abilities of the connection: Only about 30-40KByte/s when the router locks at 1012Kb/s and other direct uploads or uploading overheads can reach more than 100KByte/sec so I don't think it's a congestion at uploading that is doing it. Is there something I miss? Because I assume 13611Kbit/s should be ~1701Kbyte/sec. Is it an overheard at the ADSL level I don't understand? Could it be the ISP doing it? If it's active throttling it can't be on single connections since 2 high speed connections still go up to ~1500KByte/sec. It's not an example on torrents or other complex situations. The tests were on Ethernet, but I doubt the results would be different on wireless. I wonder if the settings of those connections at my end could be doing it, e.g. MTU settings, though I haven't touched the defaults of a common Realtek NIC.

  • Is (Ubuntu) Linux file copying algorithm better than Windows 7?

    - by Sarath
    Windows Copying is a real mess ever since Windows Vista. Even Microsoft claims they've improved the performance, from a user perspective, it's not quite visible. Even with single file the copying window appears too much time for 'Calculating' and then finishing the copy(Even after 100% completion some times the dialog remains active). At the same time, I was backing up some files in Ubuntu Linux. I felt it's really fast. Might be a feeling caused by faster UI updates. I read an informative post from Jeff Atwood few years back on Windows File Copying. but what my specific questions are Is (Ubuntu) Linux file performance is better than Windows-7? Are both algorithms, Windows and Linux is making use of multiple threads and pipelining mechanism to improve the speed? If yes, which one is better?

  • How to disabled password authentication for specific users in SSHD

    - by Nick
    I have read several posts regarding restricting ALL users to Key authentication ONLY, however I want to force only a single user (svn) onto Key auth only, the rest can be key or password. I read How to disable password authentication for every users except several, however it seems the "match user" part of sshd_config is part of openssh-5.1. I am running CentOS 5.6 and only have OpenSSH 4.3. I have the following repos available at the moment. $ yum repolist Loaded plugins: fastestmirror repo id repo name status base CentOS-5 - Base enabled: 3,535 epel Extra Packages for Enterprise Linux 5 - x86_64 enabled: 6,510 extras CentOS-5 - Extras enabled: 299 ius IUS Community Packages for Enterprise Linux 5 - x86_64 enabled: 218 rpmforge RHEL 5 - RPMforge.net - dag enabled: 10,636 updates CentOS-5 - Updates enabled: 720 repolist: 21,918 I mainly use epel, rpmforge is used to the latest version (1.6) of subversion. Is there any way to achieve this with my current setup? I don't want to restrict the server to keys only because if I lose my key I lose my server ;-)

  • How to plan/manage multi-platform (mobile) products?

    - by PhD
    Say I've to develop an app that runs on iOS, Android and Windows 8 Mobile. Now all three platforms are technically in different program languages. The only 'reuse' that I can see is that of the boxes-and-lines drawings (UML :) charts and nothing else. So how do companies/programmers manage the variation of the same product across different platforms especially since the implementation languages differ? It's 'easier' in the desktop world IMO given the plethora of languages and cross-platform libraries to make your life easier. Not so in the mobile world. More so, product line management principles don't seem to be all that applicable - what is same and variant doesn't really matter - the application is the same (conceptually) and the implementation is variant. Some difficulties that come to mind: Bug Fixing: Applications maybe designed in a similar manner but the bug identification and fixing would be radically different. A bug on iOS may/may-not be existent for that on Android. Or a bug fix approach on one platform may not be the same on another (unless it's a semantic bug like a!=b instead of a==b which would require the same 'approach' to fixing in essence Enhancements: Making a change on one platform would be radically different than on another Code-Design Divergence: They way the code is written/organized, the class structures etc., could be very different given the different implementation environments - leading to further reuse of the (above) UML models. There are of course many others - just keeping the development in sync and making sure all applications are up to the same version with the same set of features etc. Seems the effort is 3x that of a single application. So how exactly does one manage this nightmarish situation? Some thoughts: Split application to client/server to minimize the effect to client side only (not always doable) Use frameworks like Unity-3D that could take care of the cross-platform problem (mostly applicable to games and probably not to other applications etc.) Any other ways of managing a platform line? What are some proven approaches to managing/taming the effects?

  • One vs. many domain user accounts in a server farm

    - by mjustin
    We are in a migration process of a group of related computers (Intranet servers, SQL, application servers of one application) to a new domain. In the past we used one domain user account for every computer (web1, web2, appserver1, appserver2, sql1, sqlbackup ...) to access central Windows resources like network shares. Every computer also has a local user account with the same name. I am not sure if this is necessary, or if it would be easier to configure and maintain to use one domain user account. Are there key advantages / disadvantages of having one single user account vs. dedicated accounts per computer for this group of background servers? If I am not wrong, one advantage besides easier administration of the user account could be that moving installed applications and services around between the computers does not require a check of the access rights anymore. (Except where IP addresses or ports are used)

  • OS X: What does the '@' attribute on a file mean?

    - by claytontstanley
    On a Snow Leopard machine, at the Terminal: la ~/src/rmcl/ | grep RMCL -rw-r--r--@ 1 claytonstanley staff 6766167 Nov 13 2009 RMCL What is that '@' attribute? This file is part of an older OS X program that runs under Rosetta. I'm having issues where some older programs running under Rosetta require the @ attribute when opening files. But I'm not sure what that attribute is, so I have no way to know how to add/remove it. I did try a thorough Google search on this, but I wasn't able to find the answer. I would have thought this would be an easy one to find. Maybe the Google query isn't acting properly because of the single @ special character. Any info. is much appreciated. Thanks!

  • Combine OS partion with data partition on NAS4Free/FreeNAS

    - by Pak
    I recently built a NAS4Free (formerly FreeNAS) machine using a 256MB (yes, MB) USB drive for the OS. When I did the original install, I had the bright idea of making the OS partition just big enough for the OS and a then creating a second partition using the remainder of the drive to store stuff pertaining to the OS. I never really found a use for the data partition and I ended up running out of space on the OS partition, so now I'd like to combine the partitions into a single partition. Is this something that is possible to do while everything is up and running? If it comes down to it, I can take down the machine and do a fresh install of the OS using the entire space of the USB drive, but I'd like to use this as an opportunity to better familiarize myself with FreeBSD/UNIX type systems. If this is possible, will it interfere with the NAS4Free things? The data partition shows up in the web interface under the disks section. If I end up manually changing the partitions, I'd be concerned with NAS4Free getting confused by the missing partition.

  • PASS Summit Preconference and Sessions

    - by Davide Mauri
    I’m very pleased to announce that I’ll be delivering a Pre-Conference at PASS Summit 2012. I’ll speak about Business Intelligence again (as I did in 2010) but this time I’ll focus only on Data Warehouse, since it’s big topic even alone. I’ll discuss not only what is a Data Warehouse, how it can be modeled and built, but also how it’s development can be approached using and Agile approach, bringing the experience I gathered in this field. Building the Agile Data Warehouse with SQL Server 2012 http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=2821 I’m sure you’ll like it, especially if you’re starting to create a BI Solution and you’re wondering what is a Data Warehouse, if it is still useful nowadays that everyone talks about Self-Service BI and In-Memory databases, and what’s the correct path to follow in order to have a successful project up and running. Beside this Preconference, I’ll also deliver a regular session, this time related to database administration, monitoring and tuning: DMVs: Power in Your Hands http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=3204 Here we’ll dive into the most useful DMVs, so that you’ll see how that can help in everyday management in order to discover, understand and optimze you SQL Server installation, from the server itself to the single query. See you there!!!!!

  • Reporting memory usage per process/program

    - by Nick Retallack
    How can I get the current memory usage (preferably in bytes so they can be added up accurately) for all running processes individually? Can I roll up the summaries for child processes into the process that spawned them? (e.g all apache threads together). Sometimes, my server runs out of memory and becomes unresponsive. I want to discover what is using up all the memory. Unfortunately, it's likely to not be a single process. Some programs spawn hundreds of processes, each using very little memory, but it adds up. On a side note, is it normal for apache to spawn 200+ processes?

  • Extract Certs from Apache

    - by user271619
    Recently I've had to uninstall a single Self-Signed SSL Certificate from one of my Apache boxes, specifically for an outside party. That's not really a problem for me, since it was easy. What confuses me is how they knew I had a self-signed certificate. The domain I provided them was not related to the domain with the self-signed certificate. Does this mean Apache publicizes the Virtual hosts in the httpd.conf file? I asked the outside party what software they used to extract information from my server, and they provided this GitHub link: https://gist.github.com/4ndrej/4547029 I figured I'd ask the community first, before I attempt installing the Java program.

  • Is the Entity Component System architecture object oriented by definition?

    - by tieTYT
    Is the Entity Component System architecture object oriented, by definition? It seems more procedural or functional to me. My opinion is that it doesn't prevent you from implementing it in an OO language, but it would not be idiomatic to do so in a staunchly OO way. It seems like ECS separates data (E & C) from behavior (S). As evidence: The idea is to have no game methods embedded in the entity. And: The component consists of a minimal set of data needed for a specific purpose Systems are single purpose functions that take a set of entities which have a specific component I think this is not object oriented because a big part of being object oriented is combining your data and behavior together. As evidence: In contrast, the object-oriented approach encourages the programmer to place data where it is not directly accessible by the rest of the program. Instead, the data is accessed by calling specially written functions, commonly called methods, which are bundled in with the data. ECS, on the other hand, seems to be all about separating your data from your behavior.

  • Distribute Nagios to reduce false alarms

    - by GDR
    I'm currently running a single Nagios instance. From time to time, I'm getting false alarms about timeouts - for example, it says that HTTP is down on some server, but when I open it in my browser several seconds later, it loads fast, and in general there is no trace of an error. What can I do to reduce such false alarms? I'm guessing that it's because of transient network issues on my monitoring server. I guess that setting up another monitoring server on a different network would greatly help, but how do I plug it into Nagios? Is it at all possible with Nagios or do I have to switch to another monitoring system? I like my configs and, if possible, I'd like to stay with Nagios or something compatible (Icinga?)

  • Cascading KVM switches

    - by einpoklum
    I have a not-so-small number of computers (say, 5) which I want to access with a single keyboard, USB and monitor. I can get an 8-port KVM switch, which is a pretty expensive piece of hardware; however, in theory, I should be able to cascade KVM switches: Have one 4-port KVM switch between 2 other KVMs (a 2-port and a 4-port). Is this doable (with typical off-the-shelf switches and cables)? Has anyone had experience doing this? Note: I'm interested in USB-only for the keyboard and mouse, and either VGA or DVI for the display. Audio and PS/2 connections are irrelevant for me..
