  • Duplicity Errno 2 - no such file or directory

    - by Luma
    Hello, I am trying to setup a script for backing up a linux box to a CIFS share. I manually mounted the CIFS share and created a few test folders - OK I then ran duplicity manually with a rather simple command to begin with to make sure things work and well Not OK on this one :) duplicity /root file:///cifsmountfolder/existingfolder/ results: No signatures found, switching to full backup. Traceback (most recent call last): File "/usr/bin/duplicity", line 463, in <module> with_tempdir(main) File "/usr/bin/duplicity", line 458, in with_tempdir fn() File "/usr/bin/duplicity", line 449, in main full_backup(col_stats) File "/usr/bin/duplicity", line 155, in full_backup bytes_written = write_multivol("full", tarblock_iter, globals.backend) File "/usr/bin/duplicity", line 99, in write_multivol backend.put(tdp, dest_filename) File "/usr/lib/python2.5/site-packages/duplicity/backends.py", line 279, in put target_path.writefileobj(source_path.open("rb")) File "/usr/lib/python2.5/site-packages/duplicity/path.py", line 500, in writefileobj fout = self.open("wb") File "/usr/lib/python2.5/site-packages/duplicity/path.py", line 448, in open else: result = open(self.name, mode) IOError: [Errno 2] No such file or directory: '/cifsmountfolder/existingfolder/duplicity-full.2010-09-18T18:41:43-07:00.vol1.difftar.gpg' any ideas?

  • Cant get lm-sensors to load ATI Radeon temp and fan or output all settings

    - by woody
    New to Linux and having minor issues :/ . I followed this guide initially but did not recieve the proper output and did not show my ATI Radeon HD 5000 temp or fan speed. Then used this guide, same problems exhibited. No issues installing and no errors. I think its not reading i2c for some reason. The proprietary driver is installed and functioning correctly according fglrxinfo. I can use aticonfig commands and view both temp and fan. Any ideas on how to get the ATI Radeon sensors working under 'sensors'?

  • How do you get SharePoint back in sync when you change a user's sAMAccountName?

    - by Kirk Liemohn
    I have observed on SharePoint 2010 that if you change the sAMAccountName of a user after the user has logged into a SharePoint site collection, the tp_Login field in the UserInfo table does not get updated. It still has the old user Id. While the user can log into SharePoint under the new account, these new logins do not update the table. I have code that looks at the SPUser.LoginName and this value appears to be the tp_Login field value which is now old. The fact that this value is old causes my code to fail. I suspect this behavior is identical in SharePoint 2007. Is there any way to force SharePoint to recognize the new sAMAccountName? I suspect that profile synchronization might help, but I would like for my solution to work with WSS 3.0 and SharePoint 2010 Foundation. I considered manually updating the database table, but I would like to stick with supported approaches.

  • SQL Server Agent 2005 job runs but provides no output

    - by alimack
    Essentially I have a job which runs in BIDS and as as a stand lone package and while it runs under the SQL Server Agent it doesn't complete properly (no error messages though). The job steps are: 1) Delete all rows from table; 2) Use For each loop to fill up table from Excel spreasheets; 3) Clean up table. I've tried this MS page (steps 1 & 2), didn't see any need to start changing from Server side security. Also SQLServerCentral.com for this page, no resolution. How can I get error logging or a fix?

  • Which way should we choose to shorten backup time?

    - by facebook-100005613813158
    A company performs a full backup for its data in a daily basis for disaster recovery purposes. However, their backup process cannot be completed within the assigned backup time window. What would you recommend to this company about how to restructure its backup environment in order to minimize the backup time? We got 4 candidates, 1. Perform LAN based backup 2. Weekly full backup and daily incremental 3. Weekly full backup and daily cumulative 4. Add more ISL to increase bandwidth when comparing incremental backup with cumulative backup ,incremental backup time is surely shorter than cumulative backup time .But I don's know adding more ISL is allowed in an existing storage system,or can this operation really shorten backup time ?

  • Advice for programming a lobby for a network multiplayer game?

    - by Milo
    I'm working on learning network programming. I'm working on a simple card game. The basic idea is: Players enter the lobby Players see tables Players sit at an empty seat Once they sit, they do not need any information from the lobby, they see the card table and the data about the other players and so forth. I've programmed the server portion for the game itself. The clients connect to my server object and the server then receives and sends messages; quite simple. The tricky concepts for me are: What's a good way to run many tables at the same time? What's a good way to keep the lobby consistently updated for each person in the lobby (eg: MSG_TABLE_FILLED, 22) Ideally I'd like to have 1 server exe for all of this and to have to deal with multithreading as little as possible. I'm going to use the enet library. I was thinking that each time a game session starts, I push a new Game and I map the client IPs to that table, then I just route messages from those clients to that Game. Since enet supports channels I was thinking of using 2 channels per table, one for the game messages and one for in game chat. Would something like this work? Does anyone have any advice / design ideas for a game with a lobby and many tables? Is there a usual way this is done that I'm overlooking? Any conceptual ideas or even c/c++ code examples would be very helpful. Thanks

  • External USB Drive

    - by ErocM
    I have a server that I hooked up an external USB drive. It was formatted in windows and has files on it already. I'm new to Ubuntu so please be patient... I have two questions: Will Ubuntu see the drive since it was formatted in windows? How do I mount this drive or rather, how do I know it's seen by Ubuntu? Thanks! I did fdisk -l and this is what I have but I don't see it.

  • Changing Recovery Model in Replicated Database

    - by Rob
    I now am the proud owner of two servers that replicate with each other. I had nothing to do with the install, but (of course), now i have to support the databases. Both databases are in the Simple recovery model, but the users want to ensure as little data loss as possible so I'm thinking that I should change the recovery model over to full and start doing transaction log backups. I wasn't planning on backing up the subscribing database, only the publisher. Is this the right plan? Do I need to switch both the Subscriber and and the publisher to Full, or can I leave the subscriber in Simple, but have the Publisher in Full? When I change the recovery model in one (or both) do the databases need to be offline? Thanks

  • SQL Server 2005: reclaiming LOB space

    - by AndrewD
    Hello all, I've got an interesting table in one of my DBs that's confusing me. The table in question has a a few LOB type columns (two nvarchar(max) and a text) and it looks like there's some strange space issues going on. from this query: SELECT type_desc, SUM(total_pages) *8 [Size in kb] FROM sys.partitions p JOIN sys.allocation_units a ON p.partition_id = a.container_id WHERE p.object_id = OBJECT_ID('asyncoperationbase') GROUP BY type_desc; I get: type_desc Size in kb IN_ROW_DATA 27936 LOB_DATA 1198144 ROW_OVERFLOW_DATA 0 (there's just under 8000 rows in the table, each row has a data length of ~10k - not counting the LOB data) here's where it gets somewhat interesting: SELECT ( SUM(DATALENGTH(aob.WorkflowState)) + SUM(DATALENGTH(aob.[Message]))+ SUM(DATALENGTH(aob.[Data])) ) / 1024 FROM AsyncOperationBase aob returns: 76617 As I'm reading it - it looks like the ~75mb of LOB data is using over a gig of space to be stored - I would expect some overhead but not quit that much. Thanks, Andrew

  • Laptop drains of quickly with battery

    - by Shyam
    I am a user since years in ubuntu and I have not come across this problem with ubuntu till date. My battery drains off immediately after I unplug my AC power. The options I tried: 1) checked the battery state with : cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: charged present rate: 0 mA remaining capacity: 392 mAh present voltage: 12476 mV Initially it was showing charging state: charging after 5mins it started displaying as charged. ! Based on that if I remove my AC Power it shows low battery notification. 2) When I run acpi : acpi -b Battery 0: Unknown, 9% The battery state shows as unknown. But initially when we plug-in to AC adapter acpi -b Battery 0: Charging, 9%, 13:04:00 until charged 3) When the check the same with : upower -i /org/freedesktop/UPower/devices/battery_BAT0 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/device:02/PNP0C09:00/PNP0C0A:00/power_supply/BAT0 vendor: HP power supply: yes updated: Thu Nov 1 16:06:40 2012 (20 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging energy: 4.2336 Wh energy-empty: 0 Wh energy-full: 33.1128 Wh energy-full-design: 33.1128 Wh energy-rate: 5.6052 W voltage: 12.474 V time to full: 5.2 hours percentage: 12.7854% capacity: 100% technology: lithium-ion Is the power stats output, It says 5hrs to charge completely, If I charge it even more than 5hrs and unplug the AC power, It again cribs stating LOW BATTERY !! The same thing does not happen with Windows7. Any suggestions/ help will be greatly appreciated.

  • Optimize Many-to-Many with SUMMARIZE and Other Techniques

    - by Marco Russo (SQLBI)
    We are still in the early days of DAX and even if I have been using it since 2 years ago, there is still a lot to learn on that. One of the topics that historically interests me (and many of the readers here, probably) is the many-to-many relationships between dimensions in a dimensional data model. When I and Alberto wrote the The Many to Many Revolution 2.0 we discovered the SUMMARIZE based pattern very late in the whitepaper writing. It is very important for performance optimization and it should be always used. In the last month, Gerhard Brueckl also presented an approach based on cross table filtering behavior that simplify the syntax involved, even if it’s harder to explain how it works internally. I published a short article titled Optimize Many-to-Many Calculation in DAX with SUMMARIZE and Cross Table Filtering on SQLBI website just to provide a quick reference to the three patterns available. A further study is still required to compare performance between SUMMARIZE and Cross Table Filtering patterns. Up to now, I haven’t observed big differences between them, even if their execution plans might be not identical and this suggest me that depending on other conditions you might favor one over the other.

  • asp.net mvc vs angular.js model binding

    - by aw04
    So I've noticed a trend lately of .net web developers using angular.js on the client side of applications and I've become more curious as I play around with angular and compare it to how I would do things in asp.net mvc. I'll give a quick example of what really got me thinking. I recently came across a situation at work (I work in a .net environment) where I needed to create a table bound to a collection of objects that had the ability to add and remove rows/items from the collection. I had an add button that created a new object and appended a row to the end of the table, and a remove button in each row to remove a particular object/row. Using asp.net mvc, I first found myself making an ajax call to the server for each operation, updating the server side model, and refreshing part of the page to show the result in the table. This worked but I didn't really like the idea of calling the server to update the model each time, so I tried to come up with a solution to do this on the client side. It turned out to be quite a task, as I had to generate the html on add with validation and all and the correct indexing for the model binding to work. It got worse on remove, as I ended up with a crazy string replace function to recreate the indexes on each item to satisfy the binding requirements (if an item other than the last is removed, the indexes are no longer correct). Now out of curiosity, I tried to recreate this at home in angular (which I had no experience with) and it took me all of about 10 minutes with simple functions to add and remove items from the client side model. This is just one example, but it seems to me that I'm able to achieve the same results with far fewer calls to the server in angular because of the fact that it binds to a client side model. So my question is, is this a distinct advantage of using a javascript mvc framework or am I somehow under utilizing the power of asp.net mvc and am I right in thinking that these operations should be done on the client and have no business requiring calls to the server?

  • How atomic is a SELECT INTO?

    - by leo.pasta
    Last week I got an interesting situation that prompted me to challenge a long standing assumption. I always thought that a SELECT INTO was an atomic statement, i.e. it would either complete successfully or the table would not be created. So I got very surprised when, after a “select into” query was chosen as a deadlock victim, the next execution (as the app would handle the deadlock and retry) would fail with: Msg 2714, Level 16, State 6, Line 1 There is already an object named '#test' in the database. The only hypothesis we could come up was that the “create table” part of the statement was committed independently from the actual “insert”. We can confirm that by capturing the “Transaction Log” event on Profiler (filtering by SPID0). The result is that when we run: SELECT * INTO #results FROM master.sys.objects we get the following output on Profiler: It is easy to see the two independent transactions. Although this behaviour was a surprise to me, it is very easy to workaround it if you feel the need (as we did in this case). You can either change it into independent “CREATE TABLE / INSERT SELECT” or you can enclose the SELECT INTO in an explicit transaction: SET XACT_ABORT ON BEGIN TRANSACTION SELECT * INTO #results FROM master.sys.objects COMMIT

  • Sync Google Contacts with QuickBooks

    - by dataintegration
    The RSSBus ADO.NET Providers offer an easy way to integrate with different data sources. In this article, we include a fully functional application that can be used to synchronize contacts between Google and QuickBooks. Like our QuickBooks ADO.NET Provider, the included application supports both the desktop versions of QuickBooks and QuickBooks Online Edition. Getting the Contacts Step 1: Google accounts include a number of contacts. To obtain a list of a user's Google Contacts, issue a query to the Contacts table. For example: SELECT * FROM Contacts. Step 2: QuickBooks stores contact information in multiple tables. Depending on your use case, you may want to synchronize your Google Contacts with QuickBooks Customers, Employees, Vendors, or a combination of the three. To get data from a specific table, issue a SELECT query to that table. For example: SELECT * FROM Customers Step 3: Retrieving all results from QuickBooks may take some time, depending on the size of your company file. To narrow your results, you may want to use a filter by including a WHERE clause in your query. For example: SELECT * FROM Customers WHERE (Name LIKE '%James%') AND IncludeJobs = 'FALSE' Synchronizing the Contacts Synchronizing the contacts is a simple process. Once the contacts from Google and the customers from QuickBooks are available, they can be compared and synchronized based on user preference. The sample application does this based on user input, but it is easy to create one that does the synchronization automatically. The INSERT, UPDATE, and DELETE statements available in both data providers makes it easy to create, update, or delete contacts in either data source as needed. Pre-Built Demo Application The executable for the demo application can be downloaded here. Note that this demo is built using BETA builds of the ADO.NET Provider for Google V2 and ADO.NET Provider for QuickBooks V3, and will expire in 2013. Source Code You can download the full source of the demo application here. You will need the Google ADO.NET Data Provider V2 and the QuickBooks ADO.NET Data Provider V3, which can be obtained here.

  • How should I share variables between instances/classes?

    - by tesselode
    I'm making a game using LOVE, so everything is programmed in Lua. I've been experimenting with using classes and object orientation recently. I've found out that a nice system to use is having most of the game's code in different classes, and having a table of instances with all of the instances of any class in it. This way, I can go through every instance of every class and update and draw it by calling the same function. There is a problem, though. Let's say I have an instance of a player with variables for health and recharge time of a weapon. I also have a master instance which is responsible for drawing the HUD. How can I tell the master instance what the player's health is? Bad solutions: Assuming that the player instance will always have the same position in the table - that can be easily changed. Using global variables. Global variables are evil. Have the master instance outside of the instances table, and have the player set variables inside the master instance, which it then uses for HUD drawing. This is really bad because now I have to make a duplicate of every variable the master instance needs. What is the proper, standard way of sharing variables between instances? Do I need to change the way I keep track of instances?

  • SQL SERVER – Using MAXDOP 1 for Single Processor Query – SQL in Sixty Seconds #008 – Video

    - by pinaldave
    Today’s SQL in Sixty Seconds video is inspired from my presentation at TechEd India 2012 on Speed up! – Parallel Processes and Unparalleled Performance. There are always special cases when it is about SQL Server. There are always few queries which gives optimal performance when they are executed on single processor and there are always queries which gives optimal performance when they are executed on multiple processors. I will be presenting the how to identify such queries as well what are the best practices related to the same. In this quick video I am going to demonstrate if the query is giving optimal performance when running on single CPU how one can restrict queries to single CPU by using hint OPTION (MAXDOP 1). More on Errors: Difference Temp Table and Table Variable – Effect of Transaction Effect of TRANSACTION on Local Variable – After ROLLBACK and After COMMIT Debate – Table Variables vs Temporary Tables – Quiz – Puzzle – 13 of 31 I encourage you to submit your ideas for SQL in Sixty Seconds.

  • Files backup utility with incremental backups that would keep backup device clean

    - by Wojtek
    I've tested a few of backup utilities and still haven't found one that would satisfy me. Almost every one of them has two options: - full backup - not an option to use frequently - incremental backup - seems right, but there's one thing about it: Incremental backup builds on a base of a full backup, backing up only those files, that were created/changed. The thing is, that after some time you've got a lot of unwanted files from the old backups bloating your backup device. Also, if you'd accidentally delete your full (first) backup file, then the differential backups would be corrupted (you wouldn't be able to restore them). The thing I'm looking for is a program, that would backup files simply by copying them. It would check the backup device whether it contains the file (unchanged): - if yes, it should proceed to the next file (we've got current version backed up) - if no, it would copy the file to the backup device - if the device contains a file that is no longer on our disk, the program would delete it from the backup device Is there any such utility, that would work this way? If not, do you have any hints on how to backup fairly big amounts of data (around 20gb) quite frequently with incremental backups and not be exposed to those unwanted effects of backup size puffing up?

  • I can't install Ubuntu on my Dell Inspiron 15R at all

    - by Kieran Rimmer
    I'm attempting to install Ubuntu 12.04LTS, 64 bit onto a Dell Inspiron 15R laptop. I've shrunk down one of the windows partitions and even used gparted to format the vacant space as ext4. However, the install disk simply does not present any options when it comes to the partitioning step. What I get is a non-responsive blank table As well as the above, I've changed the BIOS settings so that USB emulation is disabled (as per Can't install on Dell Inspiron 15R), and changed the SATA Operation setting to all three possible options. Anyway, the install CD will bring up the trial version of ubuntu, and if I open terminal and type sudo fdisk -l, I get this: Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xb4fd9215 Device Boot Start End Blocks Id System /dev/sda1 63 80324 40131 de Dell Utility Partition 1 does not start on physical sector boundary. /dev/sda2 * 81920 29044735 14481408 7 HPFS/NTFS/exFAT /dev/sda3 29044736 1005142015 488048640 7 HPFS/NTFS/exFAT /dev/sda4 1005154920 1953520064 474182572+ 83 Linux Disk /dev/sdb: 32.0 GB, 32017047552 bytes 255 heads, 63 sectors/track, 3892 cylinders, total 62533296 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xb4fd923d Device Boot Start End Blocks Id System /dev/sdb1 2048 16775167 8386560 84 OS/2 hidden C: drive If I type 'sudo parted -l', I get: Model: ATA WDC WD10JPVT-75A (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/4096B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 41.1MB 41.1MB primary fat16 diag 2 41.9MB 14.9GB 14.8GB primary ntfs boot 3 14.9GB 515GB 500GB primary ntfs 4 515GB 1000GB 486GB primary ext4 Model: ATA SAMSUNG SSD PM83 (scsi) Disk /dev/sdb: 32.0GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 8589MB 8588MB primary Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only.

  • Getting rid of Massive View Controller in iOS?

    - by Earl Grey
    I had a discussion with my colleague about the following problem. We have an application where we need filtering functionality. On any main screen within the upper navigation bar, there is a button in the upper right corner. Once you touch that button, an custom written Alert View like view will pop up modally, behind it a semitransparent black overlay view. In that modal view, there is a table view of options, and you can choose one exclusively. Based on your selection, once this modal view is closed, the list of items in the main view is filtered. It is simply a modally presented filter to filter the main table view.This UI design is dictated by the design department, I cannot do anything about it so let accept this as a premise. Also the main filter button in the navbar will change colours to indicate that the filter is active. The question I have is about implementation. I suggested to my colleague that we create a separate XYZFilter class that will be an instance created by the main view controller acquire the filtering options handle saving and restoration of its state - i.e. last filter selected provide its two views - the overlay view and the modal view be the datasource for the table in its modal view. For some unknown reason, my colleague was not impressed by that approach at all. He simply wants to do these functionalities in the main view controller, maybe out of being used to do this in the past like that :-/ Is there any fundamental problem with my approach? I want to keep the view controller small, not to have spaghetti code create a reusable component (for use outside the project) have more object oriented, decoupled approach. prevent duplication of code as we need the filtering in two different places but it looks the same in both.. Any advice?

  • Inserting HTML code with jquery

    - by J. Robertson
    One of our web applications is a page that takes in a serial number and various information is returned and displayed to the user. The serial is passed via AJAX, and based on the response, one of the following can happen - An error message is shown A new form replaces the previous form Now, the way I am handling this is to use jQuery to destroy (using $.remove()) the table that displayed the initial serial form, then I'm appending another html table that contains another form. Right now I am including that additional form as part of the html source, and just setting it to display:none, then using jQuery to show it when appropriate. However, I don't like this approach because if someone views source on the page, they can see that table html code that is not being displayed. My next thought would be to use AJAX to read in another HTML file, and append it that way. However, I am trying to keep down the number of files this project uses, and since most pages in our project will use AJAX, I could see a case where there are multiple files containing HTML snippets - and that feels sloppy to me. What is the best way to handle a case where multiple html elements are being shown and removed with jQuery?

  • SQL SERVER – Follow up – Usage of $rowguid and $IDENTITY

    - by pinaldave
    The most common question I often receive is why do I blog? The answer is even simpler – I blog because I get an extremely constructive comment and conversation from people like DHall and Kumar Harsh. Earlier this week, I shared a conversation between Madhivanan and myself regarding how to find out if a table uses ROWGUID or not? I encourage all of you to read the conversation here: SQL SERVER – Identifying Column Data Type of uniqueidentifier without Querying System Tables. In simple words the conversation between Madhivanan and myself brought out a simple query which returns the values of the UNIQUEIDENTIFIER  without knowing the name of the column. David Hall wrote few excellent comments as a follow up and every SQL Enthusiast must read them first, second and third. David is always with positive energy, he first of all shows the limitation of my solution here and here which he follows up with his own solution here. As he said his solution is also not perfect but it indeed leaves learning bites for all of us – worth reading if you are interested in unorthodox solutions. Kumar Harsh suggested that one can also find Identity Column used in the table very similar way using $IDENTITY. Here is how one can do the same. DECLARE @t TABLE ( GuidCol UNIQUEIDENTIFIER DEFAULT newsequentialid() ROWGUIDCOL, IDENTITYCL INT IDENTITY(1,1), data VARCHAR(60) ) INSERT INTO @t (data) SELECT 'test' INSERT INTO @t (data) SELECT 'test1' SELECT $rowguid,$IDENTITY FROM @t There are alternate ways also to find an identity column in the database as well. Following query will give a list of all column names with their corresponding tablename. SELECT SCHEMA_NAME(so.schema_id) SchemaName, so.name TableName, sc.name ColumnName FROM sys.objects so INNER JOIN sys.columns sc ON so.OBJECT_ID = sc.OBJECT_ID AND sc.is_identity = 1 Let me know if you use any alternate method related to identity, I would like to know what you do and how you do when you have to deal with Identity Column.

  • How To Backup Of MySQL Database Using PhpMyAdmin

    - by Jyoti
    It is very important to do backup of your MySql database, you will probably realize it when it is too late. A lot of web applications use MySql for storing the content. This can be blogs, and a lot of other things. When you have all your content as html files on your web server it is very easy to keep them safe from crashes, you just have a copy of them on your own PC and then upload them again after the web server is restored after the crash. All the content in the MySql database must also be backed up. If you have spent a lot of time making the content and it is only stored in the Mysql server, you will feel very bad if it gets lost for ever. Backing it up once every month or so makes sure you never loose too much of your work in case of a server crash, and it will make you sleep better at night. It is easy and fast, so there is no reason for not doing it. Step 1: Log into phpMyAdmin on your server. Step2: You can select the database that you would like to backup from the drop-down menu called Database. Step 3: A new page will be loaded in phpMyAdmin showing the selected database. In order to proceed with the backup click on the Export tab. Step 4: The options that you should select apart from the default ones are Save as file which will save the file locally to your computer in an .sql format and Add DROP TABLE which will add the drop table functionality if the table already exists in the database backup as shown below. Step 5: Click on the Go button to start the export/backup procedure for your database. A download window will pop up prompting for the exact place where you would like to save the file on your local computer. It is possible that the download starts automatically. This depends on your browser’s settings.

  • Renting linux server just to make backups of my personnal data ?

    - by Matthieu
    Hi all, I would like to be able to backup ALL my computers data on a Linux server. For now, I have a home server, but soon I will be travelling, without home (so no home server). I was thinking of renting a dedicated linux webserver, but this is expensive, and I don't need a fast machine "web-oriented" with mysql server and all, I just need a full SSH access (full control, and then I install my programs). Does "backup servers" exist ? Am I doing it wrong (maybe that is not a good solution) ? Note : I run Mac OS, Windows and Linux, I backup through rsync, I want full control on my backup, not an automated "magic" backup like MobileMe or anything like that. Edit : I need around 500Gb storage

  • RAM caching causes severe performance drops

    - by B T
    I have read plenty of threads on memory caching and the standard response of "large cache is good, it shouldn't effect performance", "the kernel knows best". I have recently upgraded from 12.04 to 12.10 and changed from VirtualBox to VMware Workstation and the performance differences are severe (I suspect it is because of the latter). When I am running my virtual machine the system load monitor graph shows less than 50% memory usage generally. System load indicator is showing me that the rest of my RAM is used in the cache all the time. Plain and simple this is the comparison: BEFORE Cache was very sparingly used, pretty much none of my memory usage was the cache Swappiness was 0 (caused my memory to be used first, then swap only if needed) Performance was quite good and logical RAM was used fully first, caching was minimal. I could run enough software to utilize my full 4GB of RAM without any performance degradation whatsoever Swap space was then used as needed which was obviously slower (I am on a HDD) but was still usable when the current program was loaded into memory AFTER Cache is used to fill the full 4GB as soon as my virtual machine is run Swappiness is 0 (same behaviour as before but cache uses full memory straight away) Performance is terrible and unusable while running Ubuntu software Basic things like changing windows takes 2 minutes + Changing screens happens frame by frame over sometimes up to 5 minutes Cannot run an IDE and VM like I could with ease before So basically, any suggestions on how to take my performance back to how it was before while keeping my current setup? My suspicion is VMWare is the problem, but how do I see what is tied to the use of the cache? Surely there is a way to control this behaviour in software as polished as VMware? Thanks EDIT: Could also be important to note that the behaviour differs depending on whether VMware is open or closed. If VMware is open, then the ram will lock at like 50% and 50% cache and go into the complete lock up mentioned above. Contrastingly, if VMware is closed (after being open), then the RAM will continue to rise as it needs / cache will stay as the complete remaining memory and there is no noticeable performance degradation.

  • How to create single integer index value based on two integers where first is unlimited?

    - by Jan Doggen
    I have table data containing an integer value X ranging from 1.... unknown, and an integer value Y ranging from 1..9 The data need to be presented in order 'X then Y'. For one visual component I can set multiple index names: X;Y But for another component I need a one-dimensional integer value as index (sort order). If X were limited to an upper bound of say 100, the one-dimensional value could simply be X*100 + Y. If the one-dimensional value could have been a real, it could be X + Y/10. But if I want to keep X unlimited, is there a way to calculate a single integer 'indexing' value from X and Y? [Added] Background information: I have a Gantt/TreeList component where the tasks are ordered on a TaskIndex integer. This does not need to be a real database field, I can make it a calculated field in the underlying client dataset. My table data is e.g. as follows: ID Baseline ParentID 1 0 0 (task) 5 2 1 (baseline) 8 1 1 (baseline) 9 0 0 (task) 12 0 0 (task) 16 1 12 (baseline) Task 1 has two baselines numbered 1 and 2 (IDs 8 and 5) Task 9 has no baselines Task 12 has one baseline numbered 1 (ID 16) Baselines number 1-9 (the Y variable from my question); 0 or null identify the tasks ID's are unlimited (the X variable) The user plays with visibility of baselines, e.g. he wants to see all tasks with all baselines labeled 1. This is done by updating a filter on the table. Right now I constantly have to recalculate TaskIndex after changing the filter (looping through records). It would be nice if TaskIndex could be calculated on the fly for each record knowing only the data in the current record (I work in Delphi where a client dataset has an OnCalcFields event handler, that is triggered for each record when necessary). I have no control over the inner workings of the visual component.
