• Should users be deleted after inactivity on a website?

  - by Hovaness Bartamian

  When you have a social website or a website where you can register, would you eventually delete them after a certain time (after a year of inactivity) or would you rather keep their account records for ever? I know websites like Facebook have large amount of inactive, duplicated and fake accounts. So I'm wondering if after two years of inactivity it would be alright to send the account a warning email of deletion unless they log in. Just thinking of a clean and efficient database management or any implications this may cause to new potential users.

• First steps on setting up a query based server [closed]

  - by asghar ashgari

  I got a physical server at home and I want to do the following silly project to learn the concept behind server-backend development, and then do a real project later on: Idea: Turn the server to a calculator. I want any person publicly send a query to the server (i.e., 2+2) from the terminal and the server give me the result. So the question is basically where to start, what sort of software I need to install, and what sort of program I need to write?.

• Unable connect to android phone using bluetooth

  - by archerry

  How do I connect my laptop to my HTC Wildfire through bluetooth? The laptop is running xubuntu 11.10, and I have updated Blueman to version 1.23 through their launchpad PPA. The phone is running android version 2.2.1. I can 'pair' and 'trust' the phone, but I can neither 'send files to device...' nor 'browse files on device...' I am able to connect and browse the phone using my netbook running xubuntu 10.04 and blueman version 1.21.

• How to control gnome-terminal from Python scrypt?

  - by user936401

  I am developing an application in PyGtk, and would like to launch a gnome-terminal and output commands to it. My user should then be able to modify the command, or maybe ignore using the up arrow ... etc. I have been able to launch a terminal, but can't work out how to send commands. This is how my application starts: class App(Gtk.Window): def __init__(self): Gtk.Window.__init__(self) process=subprocess.Popen(["gnome-terminal", "--class=App", "--name=app"], shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE) response,error=process.communicate()

• Movement prediction for non-shooters

  - by ShadowChaser

  I'm working on an isometric (2D) game with moderate-scale multiplayer - 20-30 players. I've had some difficulty getting a good movement prediction implementation in place. Right now, clients are authoritative for their own position. The server performs validation and broad-scale cheat detection, and I fully realize that the system will never be fully robust against cheating. However, the performance and implementation tradeoffs work well for me right now. Given that I'm dealing with sprite graphics, the game has 8 defined directions rather than free movement. Whenever the player changes their direction or speed (walk, run, stop), a "true" 3D velocity is set on the entity and a packet it sent to the server with the new movement state. In addition, every 250ms additional packets are transmitted with the player's current position for state updates on the server as well as for client prediction. After the server validates the packet, it gets automatically distributed to all of the other "nearby" players. Client-side, all entities with non-zero velocity (ie/ moving entities) are tracked and updated by a rudimentary "physics" system - basically nothing more than changing the position by the velocity according to the elapsed time slice (40ms or so). What I'm struggling with is how to implement clean movement prediction. I have the nagging suspicion that I've made a design mistake somewhere. I've been over the Unreal, Half-life, and all other movement prediction/lag compensation articles I could find, but they all seam geared toward shooters: "Don't send each control change, send updates every 120ms, server is authoritative, client predicts, etc". Unfortunately, that style of design won't work well for me - there's no 3D environment so each individual state change is important. 1) Most of the samples I saw tightly couple movement prediction right into the entities themselves. For example, storing the previous state along with the current state. I'd like to avoid that and keep entities with their "current state" only. Is there a better way to handle this? 2) What should happen when the player stops? I can't interpolate to the correct position, since they might need to walk backwards or another strange direction if their position is too far ahead. 3) What should happen when entities collide? If the current player collides with something, the answer is simple - just stop the player from moving. But what happens if two entities take up the same space on the server? What if the local prediction causes a remote entity to collide with the player or another entity - do I stop them as well? If the prediction had the misfortune of sticking them in front of a wall that the player has gone around, the prediction will never be able to compensate and once the error gets to high the entity will snap to the new position.

• Jobs - are your SQL Agent jobs talking to you enough?

  - by fatherjack

  Most DBAs will have at least a couple of servers that have SQL Agent jobs that are scheduled to do various things on a regular basis. There is a whole host of supporting configuration settings for these jobs but some of the most important are notifications. Notification settings are there to keep you up to date on how your job executions went. You have options on types of notification - email, pager, net send, or an entry in the SQL Server Event Log and you get options on when each of these channels...(read more)

• Draw images with warped triangles on a web server [migrated]

  - by epologee

  The scenario The Flash front end of my current project produces images that a web server needs to combine into a video. Both frame-rate and frame-resolution are sizeable enough that sending an image sequence to the back end is not feasible (in both time and client bandwidth). Instead, we're trying to recreate the image drawing on the back end as well. Correct and slow, or incorrect and fast The problem is that this involves quite a bit of drawing textured triangles, and two solutions we found in Python (here and there) are so inefficient, that the drawing takes about 60 seconds per frame, resulting in a whopping 7,5 hours of processing time for a 30 second clip. Unacceptable. When using a PHP-module to send commands to ImageMagick for image manipulation, the whole process is super fast (tenths of a second per frame), but ImageMagick seems to be unable to draw triangles the way we do it in the front end, so the final results do not match. Unacceptable. What I'm asking here, is if there's someone who would know a way to solve this issue, by any means necessary that would run on a web server. Warping an image Let me explain the process of the front end: Perform a Delaunay calculation on points in an image to get an evenly distributed mesh of triangles. Offset the points/vertices in the mesh, distorting or warping the image. Draw the warped triangles on a new bitmap. We can send the results (coordinates) of steps 1 and 2 to the back end, to then draw the warped triangles and save it to an image on disk (or append as a frame to the video). But that last step is what I need help with. The Question Is there an alternative to ImageMagick that can draw triangles in a bitmap? Is there some other library, like a C library, that would allow us to do this? Or could we achieve this effect more easily by switching back end technologies, like Ruby? (.Net and Java are, unfortunately, not really options right now) Many thanks. EP. P.S. I'd appreciate re-tagging efforts, I don't quite know what labels to put on this question. Thanks!

• Sending notification after an event has remained open for a specified period

  - by Loc Nhan

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Enterprise Manager (EM) 12c allows you to create an incident rule to send a notification and/or create an incident after an event has been open for a specified period. Such an incident rule will help prevent premature alerts on issues that may correct themselves within a certain amount of time. For example, there are some agents in an unstable network area, and often there are communication failures between the agents and the OMS lasting three, four minutes at a time. In this scenario, you may only want to receive alerts after an agent in that area has been in the Agent Unreachable status for at least five minutes. Note: Many non-target availability metrics allow users to specify the “number of occurrences” or the number of consecutive times metric values reach thresholds before a notification is sent. It is best to use the feature for such metrics. This article provides a step-by-step guide for creating an incident rule set to cater for the above scenario, that is, to create an incident and send a notification after the Agent Unreachable event has remained open for a five-minute duration. Steps to create the incident rule 1.     Log on to the console and navigate to Setup -> Incidents -> Incident Rules. Note: A non-super user requires the Create Enterprise Rule Set privilege, which is a resource privilege, to create an incident rule. The Incident Rules - All Enterprise Rules page displays. 2.     Click Create Rule Set … The Create Rule Set page displays. 3.     Enter a name for the rule set (e.g. Rule set for agents in flaky network areas), optionally enter a description, and leave everything else at default values, and click + Add. The Search and Select: Targets page pops up. Note:  While you can create a rule set for individual targets, it is a best practice to use a group for this purpose. 4.     Select an appropriate group, e.g. the AgentsInFlakyNework group. The Select button becomes enabled, click the button. The Create Rule Set page displays. 5.     Leave everything at default values, and click the Rules tab. The Create Rule Set page displays. 6.     Click Create… The Select Type of Rule to Create page pops up. 7.     Leave the Incoming events and updates to events option selected, and click Continue. The Create New Rule : Select Events page displays. 8.     Select Target Availability from the Type drop-down list. The page shows more options for Target Availability. 9.     Select the Specific events of type Target Availability option, and click + Add. The Select Target Availability events page pops up. 10.   Select Agent from the Target Type dropdown list. The page expands. 11.   Click the Agent unreachable checkbox, and click OK. Note: If you want to also receive a notification when the event is cleared, click the Agent unreachable end checkbox as well before clicking OK. The Create New Rule : Select Events page displays. 12.   Click Next. The Create New Rule : Add Actions page displays. 13.   Click + Add. The Add Actions page displays. 14.   Do the following: a.     Select the Only execute the actions if specified conditions match option (You don’t want the action to trigger always). The following options appear in the Conditions for Actions section. b.     Select the Event has been open for specified duration option. The Conditions for actions section expands. c.     Change the values of Event has been open for to 5 Minutes as shown below. d.     In the Create Incident or Update Incident section, click the Create Incident checkbox as following: e.     In the Notifications section, enter an appropriate EM user or email address in the E-mail To field. f.     Click Continue (in the top right hand corner). The Create New Rule : Add Actions page displays. 15.   Click Next. The Create New Rule : Specify name and Description page displays. 16.   Enter a rule name, and click Next. The Create New Rule : Review page appears. 17.   Click Continue, and proceed to save the rule set. The incident rule set creation completes. After one of the agents in the group specified in the rule set is stopped for over 5 minutes, EM will send a mail notification and create an incident as shown in the following screenshot. In conclusion, you have seen the steps to create an example incident rule set that only creates an incident and triggers a notification after an event has been open for a specified period. Such an incident rule can help prevent unnecessary incidents and alert notifications leaving EM administrators time to more important tasks. - Loc Nhan

• How to set up an rsync backup to Ubuntu securely?

  - by ws_e_c421

  I have been following various other tutorials and blog posts on setting up a Ubuntu machine as a backup "server" (I'll call it a server, but it's just running Ubuntu desktop) that I push new files to with rsync. Right now, I am able to connect to the server from my laptop using rsync and ssh with an RSA key that I created and no password prompt when my laptop is connected to my home router that the server is also connected to. I would like to be able to send files from my laptop when I am away from home. Some of the tutorials I have looked at had some brief suggestions about security, but they didn't focus on them. What do I need to do to let my laptop with send files to the server without making it too easy for someone else to hack into the server? Here is what I have done so far: Ran ssh-keygen and ssh-copy-id to create a key pair for my laptop and server. Created a script on the server to write its public ip address to a file, encrypt the file, and upload to an ftp server I have access to (I know I could sign up for a free dynamic DNS account for this part, but since I have the ftp account and don't really need to make the ip publicly accessible I thought this might be better). Here are the things I have seen suggested: Port forwarding: I know I need to assign the server a fixed ip address on the router and then tell the router to forward a port or ports to it. Should I just use port 22 or choose a random port and use that? Turn on the firewall (ufw). Will this do anything, or will my router already block everything except the port I want? Run fail2ban. Are all of those things worth doing? Should I do anything else? Could I set up the server to allow connections with the RSA key only (and not with a password), or will fail2ban provide enough protection against malicious connection attempts? Is it possible to limit the kinds of connections the server allows (e.g. only ssh)? I hope this isn't too many questions. I am pretty new to Ubuntu (but use the shell and bash scripts on OSX). I don't need to have the absolute most secure set up. I'd like something that is reasonably secure without being so complicated that it could easily break in a way that would be hard for me to fix.

• Is there an equivalent of jsqlparser but for SPARQL instead of SQL?

  I'm trying to use Java to construct a SPARQL query, and then send it off to a remote database. However, I'm new to both Java and SPARQL, so I was wondering if anyone could explain how to do this, rather than just posting a link. I heard there is a tool called jsqlparser for the same task, except that it's for a SQL to SPARQL conversion using Java. Conversion nor parser won't be necessary, just a method for constructing a query and querying the database provided by the user.

• Application stuck in TCP retransmit

  - by SandeepJ

  I am running Linux kernel 3.13 (Ubuntu 14.04) on two Virtual Machines each of which operates inside two different servers running ESXi 5.1. There is a zeromq client-server application running between the two VMs. After running for about 10-30 minutes, this application consistently hangs due to inability to retransmit a lost packet. When I run the same setup over Ubuntu 12.04 (Linux 3.11), the application never fails If you notice below, "ss" (socket statistics) shows 1 packet lost, sk_wmem_queued of 14110 (i.e. w14110) and a high rto (120000). State Recv-Q Send-Q Local Address:Port Peer Address:Port ESTAB 0 12350 192.168.2.122:41808 192.168.2.172:55550 timer:(on,16sec,10) uid:1000 ino:35042 sk:ffff880035bcb100 <- skmem:(r0,rb648720,t0,tb1164800,f2274,w14110,o0,bl0) ts sack cubic wscale:7,7 rto:120000 rtt:7.5/3 ato:40 mss:8948 cwnd:1 ssthresh:21 send 9.5Mbps unacked:1 retrans:1/10 lost:1 rcv_rtt:1476 rcv_space:37621 Since this has happened so consistently, I was able to capture the TCP log in wireshark. I found that the packet which is lost does get retransmitted and even acknowledged by the TCP in the other OS (the sequence number is seen in the ACK), but the sender doesn't seem to understand this ACK and continues retransmitting. MTU is 9000 on both virtual machines and througout the route. The packets being sent are large in size. As I said earlier, this does not happen on Ubuntu 12.04 (kernel 3.11). So I did a diff on the TCP config options (seen via "sysctl -a |grep tcp ") between 14.04 and 12.04 and found the following differences. I also noticed that net.ipv4.tcp_mtu_probing=0 in both configurations. Left side is 3.11, right side is 3.13 <<net.ipv4.tcp_abc = 0 <<net.ipv4.tcp_cookie_size = 0 <<net.ipv4.tcp_dma_copybreak = 4096 14c11 << net.ipv4.tcp_early_retrans = 2 --- >> net.ipv4.tcp_early_retrans = 3 17c14 << net.ipv4.tcp_fastopen = 0 >> net.ipv4.tcp_fastopen = 1 20d16 << net.ipv4.tcp_frto_response = 0 26,27c22 << net.ipv4.tcp_max_orphans = 16384 << net.ipv4.tcp_max_ssthresh = 0 >> net.ipv4.tcp_max_orphans = 4096 29,30c24,25 << net.ipv4.tcp_max_tw_buckets = 16384 << net.ipv4.tcp_mem = 94377 125837 188754 >> net.ipv4.tcp_max_tw_buckets = 4096 >> net.ipv4.tcp_mem = 23352 31138 46704 34a30 >> net.ipv4.tcp_notsent_lowat = -1 My question to the networking experts on this forum : Are there any other debugging tools or options I can install/enable to dig further into why this TCP retransmit failure is occurring so consistently ? Are there any configuration changes which might account for this weird behaviour.
