  • How do I stop icons appearing on the desktop in a particular area?

    - by Seamus
    When I download something to my desktop, or insert a CD or flash drive, the icon appears on my desktop. When I have conky running, the icon sometimes appears in the top right corner, underneath conky; where I can't see it. How do I stop this happening? My .conkyrc is pasted below.

  • How to resolve concurrent ramp collisions in 2d platformer?

    - by Shaun Inman
    A bit about the physics engine: Bodies are all rectangles. Bodies are sorted at the beginning of every update loop based on the body-in-motion's horizontal and vertical velocity (to avoid sticky walls/floors). Solid bodies are resolved by testing the body-in-motion's new X with the old Y and adjusting if necessary before testing the new X with the new Y, again adjusting if necessary. Works great. Ramps (rectangles with a flag set indicating bottom-left, bottom-right, etc) are resolved by calculating the ratio of penetration along the x-axis and setting a new Y accordingly (with some checks to make sure the body-in-motion isn't attacking from the tall or flat side, in which case the ramp is treated as a normal rectangle). This also works great. Side-by-side ramps, eg. \/ and /\, work fine but things get jittery and unpredictable when a top-down ramp is directly above a bottom-up ramp, eg. < or > or when a bottom-up ramp runs right up to the ceiling/top-down ramp runs right down to the floor. I've been able to lock it down somewhat by detecting whether the body-in-motion hadFloor when also colliding with a top-down ramp or hadCeiling when also colliding with a bottom-up ramp then resolving by calculating the ratio of penetration along the y-axis and setting the new X accordingly (the opposite of the normal behavior). But as soon as the body-in-motion jumps the hasFloor flag becomes false, the first ramp resolution pushes the body into collision with the second ramp and collision resolution becomes jittery again for a few frames. I'm sure I'm making this more complicated than it needs to be. Can anyone recommend a good resource that outlines the best way to address this problem? (Please don't recommend I use something like Box2d or Chipmunk. Also, "redesign your levels" isn't an answer; the body-in-motion may at times be riding another body-in-motion, eg. a platform, that pushes it into a ramp so I'd like to be able to resolve this properly.) Thanks!

  • Unable to find good parameters for behavior of a puck in Farseer

    - by Krumelur
    EDIT: I have tried all kinds of variations now. The last one was to adjust the linear velocity in each step: newVel = oldVel * 0.9f - all of this including your proposals kind of work, however in the end if the velocity is little enough, the puck sticks to the wall and slides either vertically or horizontally. I can't get rid of this behavior. I want it to bounce, no matter how slow it is. Retitution is 1 for all objects, Friction is 0 for all. There is no gravity. What am I possibly doing wrong? In my battle to learn and understand Farseer I'm trying to setup a simple Air Hockey like table with a puck on it. The table's border body is made up from: Vertices aBorders = new Vertices( 4 ); aBorders.Add( new Vector2( -fHalfWidth, fHalfHeight ) ); aBorders.Add( new Vector2( fHalfWidth, fHalfHeight ) ); aBorders.Add( new Vector2( fHalfWidth, -fHalfHeight ) ); aBorders.Add( new Vector2( -fHalfWidth, -fHalfHeight ) ); FixtureFactory.AttachLoopShape( aBorders, this ); this.CollisionCategories = Category.All; this.CollidesWith = Category.All; this.Position = Vector2.Zero; this.Restitution = 1f; this.Friction = 0f; The puck body is defined with: FixtureFactory.AttachCircle( DIAMETER_PHYSIC_UNITS / 2f, 0.5f, this ); this.Restitution = 0.1f; this.Friction = 0.5f; this.BodyType = FarseerPhysics.Dynamics.BodyType.Dynamic; this.LinearDamping = 0.5f; this.Mass = 0.2f; I'm applying a linear force to the puck: this.oPuck.ApplyLinearImpulse( new Vector2( 1f, 1f ) ); The problem is that the puck and the walls appear to be sticky. This means that the puck's velocity drops to zero to quickly below a certain velocity. The puck gets reflected by the walls a couple of times and then just sticks to the left wall and continues sliding downwards the left wall. This looks very unrealistic. What I'm really looking for is that a puck-wall-collision does slow down the puck only a tiny little bit. After tweaking all values left and right I was wondering if I'm doing something wrong. Maybe some expert can comment on the parameters?

  • Office lights on or off in programming department? How to decide? [closed]

    - by smp7d
    At my company, the programmers who sit in the same area are constantly fighting over whether the lights stay on or off. Because there is no official policy it makes it a particularly sticky situation. We are a typical cube-farm and we have those typical cube-farm fluorescent lights and smaller ones at our desks. With the lights off, it is difficult to read and you would probably need to turn on your desk light (which some people do anyway). All programmers in our department do most of their reading on their monitor because of the nature of our business. Some feel that we should have a vote to decide whether the lights stay on or off. A couple who prefer 'lights on' feel that the vote would need to be unanimous to turn them off as having them on is the more natural office setting. Those who want them off point out that all other departments keep their lights off. I have heard all of the arguments: -Fluorescent lights cause eye strain -Reading in dark causes eye strain -The desk lights can be used if light is needed -People from other departments feel uncomfortable approaching us in the "dark" -The monitors are harder to see in the light ... Right now, some of the developers turn off the lights and some turn them on. It really just depends who last walked by the switch. I am a bit sick of the controversy as it feels a bit childish at the moment. I'm tired of hearing about it and I'm tired of having to talk about it. I tried to help them decide but as I explained, voting wasn't enough. Do other programming departments have this same argument? What is the standard or traditionally accepted option in a programming area? Are there any good reasons for one way or the other outside of preference? How can we decide fairly? EDIT Just a little more info... We do not have clients/visitors come into our office. We do have windows and hall lights that make our environment plenty bearable with the lights off. It kind of resembles a meeting room that has the lights off during a powerpoint presentation.

  • Ubuntu 12.04 - PPTP VPN is the only Internet Access

    - by user212553
    I know this has been covered. I've read dozens of posts but still have questions. I have a work server whose traffic should never leave my house without encryption. The VPN is PPTP. Currently I have a cron job that checks the status of the ppp0 adapter each minute. If the connection drops, which it does fairly often, it shuts key components down. It's fairly easy to restart PPTP with "nmcli con up id 'myVPNServer'" but there's no assurance it will reconnect and I need a better way to stop traffic (other than killing apps) when ppp0 is down. The two options I've seen discussed are the firewall (UFW, Firestarter, IPTables) or the route tables. I could be easily swayed to consider the firewall option but I focused on the route tables since no new function needs to be started. My questions involve the way the route tables change and then specifics on rules. When I start the PPTP VPN the route tables change. That suggests that if the VPN drops, the table will change back, defeating my stated intent of preventing external traffic. How can I make "sticky" changes to the route table that will persist even if the VPN connection drops? Perhaps the check boxes "Ignore automatically obtained routes" or "Use this connection only for resources on it's network" (which are part of the VPN configuration options)? It would seem that, if I can force the active VPN route table to stay in effect, even when the VPN drops, that this will effectively kill any external traffic should the VPN drop. This will give me the latitude to run a routine to restart the VPN from the command line (assuming the route table rules don't prevent me re-establishing the connection). My route table, with the VPN active is (ip route list): Any comments on what 10.10.1.1 is? $ ip route list default dev ppp0 proto static 10.10.1.1 dev ppp0 proto kernel scope link src 10.10.1.11 VPN_Server_IP_Address via 192.168.1.1 dev eth0 proto static VPN_Server_IP_Address via 192.168.1.1 dev eth0 src 192.168.1.60 169.254.0.0/16 dev eth0 scope link metric 1000 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.60 metric 1

  • ASP.Net application can no longer write to DB after having run out of disk space

    - by remi.despres-smyth
    I'm a software developer troubleshooting a sticky problem on a client's production server, and I've got a bit of a problem. They have a virtual server running Windows Server 2008, SQL Server 2008 R1 and IIS7. It was provisioned with two partitions: one that has the OS (~15 Gig), and the other has IIS' web sites (another ~15 Gig). My application that's running this server has been running perfectly well, up until about an hour ago, when it started throwing System.IO.IOException: "There is not enough space on disk". As soon as my client notified me, I cleared up some space on C:\, emptied the recycle bin, and restarted SQL Server and IIS. The web server came back up and the application was running, but it no longer saves information to the database. No error message is coming up, the application can get information out of the DB, but it can no longer save data back to it. I rebooted the server, to no effect. I spoke with a sys admin at the hosting company, and he says SQL Server appears to have come up fine and the database is not in read-only mode. I confirmed that, as I can add records to tables from SQL Server Management Studio. I looked at the event log immediately after trying to save an edited record in the app, and no new events appear in there that I can tell. I'm assuming this is related to having run out of space, as it was all working fine prior to that, but I'm at a bit of a loss as to what exactly needs a kick in the pants to get going again. Can anyone help me out? What the heck is going on here?

  • Keyboards for kiosk/outdoor/abusive environments?

    - by Justin Scott
    We have a bunch of kiosks deployed into let's just say... abusive environments. The enclosures we had built are touch as nails, and the HP thin client computers are working great. The keyboards that were purchased for the project have been nothing but problems. They're a generic brand direct from a Chinese manufacturer. They're stainless steel with keys mounted from the inside and a trackball, but they've been deployed for only a month and nearly 20% of them are already out of service due to keys sticking, keys not working, trackball problems, water damage, and a variety of other issues. Are there any kiosk keyboards that can take a beating without breaking so easily? Ideally they should be tamper-proof (keys can't be removed), waterproof, lettering should be engraved into the keys, trackball, option for a single mouse button would be nice, and some protection to keep debris out of the keys so they don't stick (sticky cleaners, food debris, etc.). Does such a beast exist? Everything we've looked at is susceptible to easy damage. We need the M1 Abrams Tank of keyboards. Any suggestions?

  • locked files on HFS+ home partition shared between OSX/Linux

    - by HazyBlueDot
    I dual boot into Arch Linux and OS X 10.6 on my MacBook pro. I synced my UID between both OSes and created an HFS partition (with no journaling) to use as a shared home/Users partition. For the most part it works just as I'd expect, but sometimes when I'm booted into OS X certain files are "locked" (when I get info on a particular file the "Locked" box is checked under the "General" pane. I can resolve the issue by manually unchecking the box) and/or I get "Operation not permitted" when I try deleting or chmod'ing a file. In both cases I don't see anything out of the ordinary on the permission bits displayed with ls -l, except for a trailing '@' character in the position where the sticky bit would normally occur: -rw-r--r--@ 1 myuser mygroup 296 Mar 29 11:44 myfile This '@' character shows up on ALL normal files, so doesn't seem to be linked to the locked/operation not permission situation. On the Linux side of things I never have permission problems. To the best of my limited knowledge and experience with ACLs I've not found any ACLs on any of the files in question. For what it's worth, I do most of my file editing using emacs (Aquamacs in OSX), is it possible it is setting weird permission bits? What is the "locked" setting that OS X uses and does it have a permission bit equivalent (so at the very least I could recursively unlock all files in my home directory from the terminal) why might some, but not other files get "locked" when booting into OS X what is the meaning of the '@' character?

  • Conky starts above windows in Ubuntu Maverick

    - by DesertIvy
    Hey guys, I did not run into this problem until I upgraded my Ubuntu box to Maverick Meerkat (10.10). Basically, whenever I start my computer, conky runs as expected, except it gets drawn over any windows that I load (see screenshot). To fix this for a single session, I simply restart conky by running killall conky; conky in a terminal. Conky gets re-drawn below active windows (namely, only appearing on my desktop), and does not have the border/drop-shadow, but I have to do this every time I start a new session. Is there a simple way to fix this? I have a small shell script that I run on startup, but it does not seem to solve the problem. #!/bin/bash sleep 10 && conky; sleep 5 && killall conky; conky; Below is the non-text part of my .conkyrc file. # Conky settings # background yes update_interval 1 cpu_avg_samples 2 net_avg_samples 2 override_utf8_locale yes double_buffer yes no_buffers yes text_buffer_size 2048 #imlib_cache_size 0 temperature_unit fahrenheit # Window specifications # own_window yes own_window_type override own_window_transparent yes own_window_hints undecorate,sticky,skip_taskbar,skip_pager,below border_inner_margin 0 border_outer_margin 0 minimum_size 200 250 maximum_width 200 alignment tr gap_x 220 gap_y 280 # Graphics settings # draw_shades no draw_outline no draw_borders no draw_graph_borders no # Text settings # use_xft yes xftfont caviar dreams:size=8 xftalpha 0.5 uppercase no temperature_unit celsius default_color FFFFFF # Lua Load # lua_load ~/.lua/scripts/clock_rings.lua lua_draw_hook_pre clock_rings

  • Cable management techniques

    - by cornjuliox
    How do you manage the giant jungle of cables behind your PC? When you have 2 or more PCs next to each other, you wind up with this giant mess cables that's a pain in the neck to clean especially when both computers are running 24/7 and any fidgeting with the cables is likely to cause data loss and/or angry users. So far I've tried masking tape, cable ties and plain old string but none have been very effective. The masking tape kept the cables in place, but over time they ended up leaving this awful sticky residue on the sides of the cables that just won't come off gets all over your fingers and is horrible horrible horrible. I have nightmares about that stuff. We used cable ties and 'folded' up some of the longer cables so that they weren't any longer than they needed to be, but this meant that the position of some of our devices like the keyboard and the mouse were essentially 'fixed' until we removed the ties. The string didn't work much differently and required that we tie them properly or risk it coming loose. I would switch to a wireless keyboard and mouse, but I don't want to have to deal with the added expense of batteries, even the rechargable ones. Plus I don't want them to die on me at a crucial moment (happened to me once while playing Firearms _<). How do large offices and data centers manage their masses of cable?

  • Can a pool of memcache daemons be used to share sessions more efficiently?

    - by Tom
    We are moving from a 1 webserver setup to a two webserver setup and I need to start sharing PHP sessions between the two load balanced machines. We already have memcached installed (and started) and so I was pleasantly surprized that I could accomplish sharing sessions between the new servers by changing only 3 lines in the php.ini file (the session.save_handler and session.save_path): I replaced: session.save_handler = files with: session.save_handler = memcache Then on the master webserver I set the session.save_path to point to localhost: session.save_path="tcp://localhost:11211" and on the slave webserver I set the session.save_path to point to the master: session.save_path="tcp://192.168.0.1:11211" Job done, I tested it and it works. But... Obviously using memcache means the sessions are in RAM and will be lost if a machine is rebooted or the memcache daemon crashes - I'm a little concerned by this but I am a bit more worried about the network traffic between the two webservers (especially as we scale up) because whenever someone is load balanced to the slave webserver their sessions will be fetched across the network from the master webserver. I was wondering if I could define two save_paths so the machines look in their own session storage before using the network. For example: Master: session.save_path="tcp://localhost:11211, tcp://192.168.0.2:11211" Slave: session.save_path="tcp://localhost:11211, tcp://192.168.0.1:11211" Would this successfully share sessions across the servers AND help performance? i.e save network traffic 50% of the time. Or is this technique only for failovers (e.g. when one memcache daemon is unreachable)? Note: I'm not really asking specifically about memcache replication - more about whether the PHP memcache client can peak inside each memcache daemon in a pool, return a session if it finds one and only create a new session if it doesn't find one in all the stores. As I'm writing this I'm thinking I'm asking a bit much from PHP, lol... Assume: no sticky-sessions, round-robin load balancing, LAMP servers.

  • Why does this rsnapshot exclude not work?

    - by bstpierre
    Rsnapshot passes excludes directly to rsync, but rsync's behavior appears inconsistent. I've simplified my rsnapshot backup test to the following directory tree (this tree will be backed up): gorilla:~# find /tmp/snaptest -exec file {} \; /tmp/snaptest: directory /tmp/snaptest/SKIPTHIS: directory /tmp/snaptest/SKIPTHIS/xyz: directory /tmp/snaptest/SKIPTHIS/xyz/testing: ASCII text /tmp/snaptest/SKIPTHIS/bar: ASCII text /tmp/snaptest/SKIPTHIS/foo: ASCII text /tmp/snaptest/SKIPTHIS.txt: ASCII text My config file: config_version 1.2 snapshot_root /tmp/backup-media no_create_root 1 cmd_cp /bin/cp cmd_rm /bin/rm cmd_rsync /usr/bin/rsync cmd_ssh /usr/bin/ssh cmd_logger /usr/bin/logger cmd_du /usr/bin/du interval hourly 6 interval daily 7 interval weekly 4 interval monthly 3 verbose 3 loglevel 3 logfile /media/maxtor-one-touch/rsnapshot.log lockfile /media/maxtor-one-touch/backups/.rsnapshot.pid rsync_short_args -a rsync_long_args --delete --numeric-ids --relative --delete-excluded exclude "SKIPTHIS/**" link_dest 1 backup /tmp/snaptest snaptest The result: gorilla:~# rsnapshot -c /tmp/snaptest.conf hourly echo 12638 > /media/maxtor-one-touch/backups/.rsnapshot.pid mkdir -m 0755 -p /tmp/backup-media/hourly.0/ /usr/bin/rsync -a --delete --numeric-ids --relative --delete-excluded \ --exclude="SKIPTHIS/**" /tmp/snaptest \ /tmp/backup-media/hourly.0/snaptest touch /tmp/backup-media/hourly.0/ rm -f /media/maxtor-one-touch/backups/.rsnapshot.pid gorilla:~# find /tmp/backup-media/ -exec file {} \; /tmp/backup-media/: directory /tmp/backup-media/hourly.0: directory /tmp/backup-media/hourly.0/snaptest: directory /tmp/backup-media/hourly.0/snaptest/tmp: sticky directory /tmp/backup-media/hourly.0/snaptest/tmp/snaptest: directory /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS: directory /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS/xyz: directory /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS/xyz/testing: ASCII text /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS/bar: ASCII text /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS/foo: ASCII text /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS.txt: ASCII text My confusion stems from the fact that if I copy-paste the rsync command echoed by rsnapshot, the SKIPTHIS directory is excluded!

  • White Screen, No Errors.

    - by GruffTech
    So.. Interesting problem for you guys, As I'm completely lost as to what to do, or where to take the next step. Server & Application Environment. CentOS release 5.3 (Final) Apache 2.2.3-22 EnableSendfile off EnableMMAP off ErrorLog logs/error_log LogLevel debug PHP-5.2.6-2 error_reporting = E_ALL display_errors = on log_errors = on max_execution_time=300 max_input_time=60 memory_limit=512mb Kohana 2.3 PHP Environment. HAProxy 1.3.15.6-2 MemCacheD 1.2.6-1 Our application is split between 3 web servers, mounting a NFS Storage server, and sticky load balancing between the 3 web servers. The application seemingly runs great, but every so often, instead of loading, the application just shows a pure white page. Not a 404 Error, or a 500 Server Error, a clean white page. And it returns instantly, so its not a execution time error. Nothing in the Error log, or Server-Error Log, Proxy log shows standard proxied connection, Just the standard 200-Status in Access log, with 256 bytes transferred. To me, this leads to tell me that the application itself is having a problem. A rare, unexplainable, seemingly random, problem that causes what we've now called the "White Screen of Death." Our developers all say that since there is nothing going to our error logs, that it must be a server problem. But I say the same thing, There's nothing going to ANY of our logs (relevent to this anyway), and we're not having httpd children crash from what i can tell. Any ideas on how i can increase my logs, or somehow prove that its not a bug in PHP, Apache, CentOS, ect? Or if it is somehow a bug, identify it?

  • IIS 7 and ASP.NET State Service Configuration

    - by Shawn
    We have 2 web servers load balanced and we wanted to get away from sticky sessions for obvious reasons. Our attempted approach is to use the ASP.NET State service on one of the boxes to store the session state for both. I realize that it's best to have a server dedicated to storing sessions but we don't have the resources for that. I've followed these instructions to no avail. The session still isn't being shared between the two servers. I'm not receiving any errors. I have the same machine key for both servers, and I've set the application ID to a unique value that matches between the two servers. Any suggestions on how I can troubleshoot this issue? Update: I turned on the session state service on my local machine and pointed both servers to the ip address on my local machine and it worked as expected. The session was shared between both servers. This leads me to believe that the problem might be that I'm not using a standalone server as my state service. Perhaps the problem is because I am using the ip address 127.0.0.1 on one server and then using a different ip address on the other server. Unfortunately when I try to use the network ip address as opposed to localhost the connection doesn't seem to work from the host server. Any insight on whether my suspicions are correct would be appreciated.

  • CloudFront with Custom Origin and ELB

    - by kmfk
    We are using CloudFront for our static assets but also wanted to allow for Gzip. We set up a new distribution with a custom origin pointing back to our application servers which are behind a elastic load balancer. We manually keep the files in sync across the cluster and update them when we publish. However, with this set up, we get nothing but Miss and RefreshHits from CloudFront, which so far has defeated the purpose. Is there any additional settings in order to use an ELB as your custom origin? In the docs, it references this as a viable solution. It appears when we point the distribution to a single server in our production cluster, cloudfront properly caches our assets. Is it possible that the sticky sessions cookie and the subsequent header that gets added by it could be an issue? Cache-Control: no-cache="set-cookie" //Added by load balancer Any ideas? FYI - currently, we have our custom origin pointing to a single EC2 instance, so caching is working correctly - in case you try to curl the file below. Example headers: curl -I http://static.quick-cdn.com/css/9850999.css HTTP/1.0 200 OK Accept-Ranges: bytes Cache-Control: max-age=3700 Cache-Control: no-cache="set-cookie" Content-Length: 23038 Content-Type: text/css Date: Thu, 12 Apr 2012 23:03:52 GMT Last-Modified: Thu, 12 Apr 2012 23:00:14 GMT Server: Apache/2.2.17 (Ubuntu) Vary: Accept-Encoding X-Cache: RefreshHit from cloudfront X-Amz-Cf-Id: K_q7Zy3_jdzlEJ85ukELVtdx1GmuXqApAbZZ7G0fPt0mxRMqPKX5pQ==,RzJmPku-rEIO9WlvuSoKa8hiAaR3dLk5KC4cQMWWrf_MDhmjWe8n6A== Via: 1.0 28c34f9fbf559a21ee16594849e4fc9c.cloudfront.net (CloudFront) Connection: close

  • Inheriting file ownership on linux

    - by John Hunt
    We have an ongoing problem here at work. We have a lot of websites set up on shared hosts, our cms writes many files to these sites and allows users of the sites to upload files etc.. The problem is that when a user uploads a file on the site the owner of that file becomes the webserver and therefore prevents us being able to change permissions etc via FTP. There are a few work arounds, but really what we need is a way to set a sticky owner if that's possible on new files and directories that are created on the server. Eg, rather than php writing the file as user apache it takes on the owner of the parent directory. I'm not sure if this is possible (I've never seen it done.) Any ideas? We're obviously not going to get a login for apache to the server, and I doubt we could get into the apache group either. Perhaps we need a way of allowing apache to set at least the group of a file, that way we could set the group to our ftp user in php and set 664 and 775 for any files that are written? Cheers, John.

  • PHP on several servers with session-sharing

    - by Etu
    there's certanly other threads about this, but I have one more question. We are about to scale the website at work to have more than one server. And we need to share the sessions between the servers. We have been looking into different solutions, one in memcached and use Memcached as sessionhandler in PHP. That will probably work. And the idea would be to run memcached on every machine and let all webservers access all other servers memcached servers, and then we have shared sessions between the machines, yay. (we have no resources to setup with sticky-sessions yet, that's a later project. we need this running, and we need this running now. and we will loadbalance with DNS for a starter) But then... If I want to take one server down, say, for maintenance, or a server crashes, or whatever reason. I don't want the users to just loose their sessions and have to start from the beginning... That's why we need some kind of replication, which Memcached does not support. Then I found http://repcached.lab.klab.org/ -- which has multi-master replication of memcached, which is great, and is what I want. But does it work with 2 machines? Say 3, 5, 10? For future scaling. I also looked into redishttp://redis.io/ -- which also seems great, but is a bit more "shaky" with the php-session-handler support, and no multi-master-replication. The thing is that I like to use memcached, but I want to be able to power down one of two boxes without loosing half of the sessions. Any suggestions?

  • Migrating SQL Server Databases – The DBA’s Checklist (Part 3)

    - by Sadequl Hussain
    Continuing from Part 2 of the Database Migration Checklist series: Step 10: Full-text catalogs and full-text indexing This is one area of SQL Server where people do not seem to take notice unless something goes wrong. Full-text functionality is a specialised area in database application development and is not usually implemented in your everyday OLTP systems. Nevertheless, if you are migrating a database that uses full-text indexing on one or more tables, you need to be aware a few points. First of all, SQL Server 2005 now allows full-text catalog files to be restored or attached along with the rest of the database. However, after migration, if you are unable to look at the properties of any full-text catalogs, you are probably better off dropping and recreating it. You may also get the following error messages along the way: Msg 9954, Level 16, State 2, Line 1 The Full-Text Service (msftesql) is disabled. The system administrator must enable this service. This basically means full text service is not running (disabled or stopped) in the destination instance. You will need to start it from the Configuration Manager. Similarly, if you get the following message, you will also need to drop and recreate the catalog and populate it. Msg 7624, Level 16, State 1, Line 1 Full-text catalog ‘catalog_name‘ is in an unusable state. Drop and re-create this full-text catalog. A full population of full-text indexes can be a time and resource intensive operation. Obviously you will want to schedule it for low usage hours if the database is restored in an existing production server. Also, bear in mind that any scheduled job that existed in the source server for populating the full text catalog (e.g. nightly process for incremental update) will need to be re-created in the destination. Step 11: Database collation considerations Another sticky area to consider during a migration is the collation setting. Ideally you would want to restore or attach the database in a SQL Server instance with the same collation. Although not used commonly, SQL Server allows you to change a database’s collation by using the ALTER DATABASE command: ALTER DATABASE database_name COLLATE collation_name You should not be using this command for no reason as it can get really dangerous.  When you change the database collation, it does not change the collation of the existing user table columns.  However the columns of every new table, every new UDT and subsequently created variables or parameters in code will use the new setting. The collation of every char, nchar, varchar, nvarchar, text or ntext field of the system tables will also be changed. Stored procedure and function parameters will be changed to the new collation and finally, every character-based system data type and user defined data types will also be affected. And the change may not be successful either if there are dependent objects involved. You may get one or multiple messages like the following: Cannot ALTER ‘object_name‘ because it is being referenced by object ‘dependent_object_name‘. That is why it is important to test and check for collation related issues. Collation also affects queries that use comparisons of character-based data.  If errors arise due to two sides of a comparison being in different collation orders, the COLLATE keyword can be used to cast one side to the same collation as the other. Continues…

  • Python Coding standards vs. productivity

    - by Shroatmeister
    I work for a large humanitarian organisation, on a project building software that could help save lives in emergencies by speeding up the distribution of food. Many NGOs desperately need our software and we are weeks behind schedule. One thing that worries me in this project is what I think is an excessive focus on coding standards. We write in python/django and use a version of PEP0008, with various modifications e.g. line lengths can go up to 160 chars and all lines should go that long if possible, no blank lines between imports, line wrapping rules that apply only to certain kinds of classes, lots of templates that we must use, even if they aren't the best way to solve a problem etc. etc. One core dev spent a week rewriting a major part of the system to meet the then new coding standards, throwing away several suites of tests in the process, as the rewrite meant they were 'invalid'. We spent two weeks rewriting all the functionality that was lost, and fixing bugs. He is the lead dev and his word carries weight, so he has convinced the project manager that these standards are necessary. The junior devs do as they are told. I sense that the project manager has a strong feeling of cognitive dissonance about all this but nevertheless agrees with it vehemently as he feels unsure what else to do. Today I got in serious trouble because I had forgotten to put some spaces after commas in a keyword argument. I was literally shouted at by two other devs and the project manager during a Skype call. Personally I think coding standards are important but also think that we are wasting a lot of time obsessing with them, and when I verbalized this it provoked rage. I'm seen as a troublemaker in the team, a team that is looking for scapegoats for its failings. Since the introduction of the coding standards, the team's productivity has measurably plummeted, however this only reinforces the obsession, i.e. the lead dev simply blames our non-adherence to standards for the lack of progress. He believes that we can't read each other's code if we don't adhere to the conventions. This is starting to turn sticky. Now I am trying to modify various scripts, autopep8, pep8ify and PythonTidy to try to match the conventions. We also run pep8 against source code but there are so many implicit amendments to our standard that it's hard to track them all. The lead dev simple picks faults that the pep8 script doesn't pick up and shouts at us in the next stand-up meeting. Every week there are new additions to the coding standards that force us to rewrite existing, working, tested code. Thank heavens we still have tests, (I reverted some commits and fixed a bunch of the ones he removed). All the while there is increasing pressure to meet the deadline. I believe a fundamental issue is that the lead dev and another core dev refuse to trust other developers to do their job. But how to deal with that? We can't do our job because we are too busy rewriting everything. I've never encountered this dynamic in a software engineering team. Am I wrong to question their adherence to coding standards?
