• Data validation best practices: how can I better construct user feedback?

  - by Cory Larson

  Data validation, whether it be domain object, form, or any other type of input validation, could theoretically be part of any development effort, no matter its size or complexity. I sometimes find myself writing informational or error messages that might seem harsh or demanding to unsuspecting users, and frankly I feel like there must be a better way to describe the validation problem to the user. I know that this topic is subjective and argumentative. I've migrated this question from StackOverflow where I originally asked it with little response. Basically, I'm looking for good resources on data validation and user feedback that results from it at a theoretical level. Topics and questions I'm interested in are: Content Should I be describing what the user did correctly or incorrectly, or simply what was expected? How much detail can the user read before they get annoyed? (e.g. Is "Username cannot exceed 20 characters." enough, or should it be described more fully, such as "The username cannot be empty, and must be at least 6 characters but cannot exceed 30 characters."?) Grammar How do I decide between phrases like "must not," "may not," or "cannot"? Delivery This can depend on the project, but how should the information be delivered to the user? Should it be obtrusive (e.g. JavaScript alerts) or friendly? Should they be displayed prominently? Immediately (i.e. without confirmation steps, etc.)? Logging Do you bother logging validation errors? Internationalization Some cultures prefer or better understand directness over subtlety and vice-versa (e.g. "Don't do that!" vs. "Please check what you've done."). How do I cater to the majority of users? I may edit this list as I think more about the topic, but I'm genuinely interested in proper user feedback techniques. I'm looking for things like research results, poll results, etc. I've developed and refined my own techniques over the years that users seem to be okay with, but I work in an environment where the users prefer to adapt to what you give them over speaking up about things they don't like. I'm interested in hearing your experiences in addition to any resources to which you may be able to point me.

• Giving a Bomberman AI intelligent bomb placement

  - by Paul Manta

  I'm trying to implement an AI algorithm for Bomberman. Currently I have a working but not very smart rudimentary implementation (the current AI is overzealous in placing bombs). This is the first AI I've ever tried implementing and I'm a bit stuck. The more sophisticated algorithms I have in mind (the ones that I expect to make better decisions) are too convoluted to be good solutions. What general tips do you have for implementing a Bomberman AI? Are there radically different approaches for making the bot either more defensive or offensive? Edit: Current algorithm My current algorithm goes something like this (pseudo-code): 1) Try to place a bomb and then find a cell that is safe from all the bombs, including the one that you just placed. To find that cell, iterate over the four directions; if you can find any safe divergent cell and reach it in time (eg. if the direction is up or down, look for a cell that is found to the left or right of this path), then it's safe to place a bomb and move in that direction. 2) If you can't find and safe divergent cells, try NOT placing a bomb and look again. This time you'll only need to look for a safe cell in only one direction (you don't have to diverge from it). 3) If you still can't find a safe cell, don't do anything. for $(direction) in (up, down, left, right): place bomb at current location if (can find and reach divergent safe cell in current $(direction)): bomb = true move = $(direction) return for $(direction) in (up, down, left, right): do not place bomb at current location if (any safe cell in the current $(direction)): bomb = false move = $(direction) return else: bomb = false move = stay_put This algorithm makes the bot very trigger-happy (it'll place bombs very frequently). It doesn't kill itself, but it does have a habit of making itself vulnerable by going into dead ends where it can be blocked and killed by the other players. Do you have any suggestions on how I might improve this algorithm? Or maybe I should try something completely different? One of the problems with this algorithm is that it tends to leave the bot with very few (frequently just one) safe cells on which it can stand. This is because the bot leaves a trail of bombs behind it, as long as it doesn't kill itself. However, leaving a trail of bombs behind leaves few places where you can hide. If one of the other players or bots decide to place a bomb somewhere near you, it often happens that you have no place to hide and you die. I need a better way to decide when to place bombs.

• SSDT - What's in a name?

  - by jamiet

  SQL Server Data Tools (SSDT) recently got released as part of SQL Server 2012 and depending on who you believe it can be described as either: a suite of tools for building SQL Server database solutions or a suite of tools for building SQL Server database, Integration Services, Analysis Services & Reporting Services solutions Certainly the SQL Server 2012 installer seems to think it is the latter because it describes SQL Server Data Tools as "the SQL server development environment, including the tool formerly named Business Intelligence Development Studio. Also installs the business intelligence tools and references to the web installers for database development tools" as you can see here: Strange then that, seemingly, there is no consensus within Microsoft about what SSDT actually is. On yesterday's blog post First Release of SSDT Power Tools reader Simon Lampen asked the quite legitimate question:I understand (rightly or wrongly) that SSDT is the replacement for BIDS for SQL 2012 and have just installed this. If this is the case can you please point me to how I can edit rdl and rdlc files from within Visual Studio 2010 and import MS Access reports.To which came the following reply:SSDT doesn't include any BIDs (sic) components. Following up with the appropriate team (Analysis Services, Reporting Services, Integration Services) via their forum or msdn page would be the best way to answer you questions about these kinds of services. That's from a Microsoft employee by the way. Simon is even more confused by this and replies with:I have done some more digging and am more confused than ever. This documentation (and many others) : msdn.microsoft.com/.../ms156280.aspx expressly states that SSDT is where report editing tools are to be foundAnd on it goes....You can see where Simon's confusion stems from. He has official documentation stating that SSDT includes all the stuff for building SSIS/SSAS/SSRS solutions (this is confirmed in the installer, remember) yet someone from Microsoft tells him "SSDT doesn't include any BIDs components".I have been close to this for a long time (all the way through the CTPs) so I can kind of understand where the confusion stems from. To my understanding SSDT was originally the name of the database dev stuff but eventually that got expanded to include all of the dev tools - I guess not everyone in Microsoft got the memo.Does this sound familiar? Have we not been down this road before? The database dev tools have had upteen names over the years (do any of datadude, TSData, VSTS for DB Pros, DBPro, VS2010 Database Projects sound familiar) and I was hoping that the SSDT moniker would put all confusion to bed - evidently its as complicated now as it has ever been.Forgive me for whinging but putting meaningful, descriptive, accurate, well-defined and easily-communicated names onto a product doesn't seem like a difficult thing to do. I guess I'm mistaken!Onwards and upwards...@Jamiet

• DHCP server with multiple interfaces on ubuntu, destroys default gateway

  - by Henrik Alstad

  I use Ubuntu, and I have many interfaces. eth0, which is my internet connection, and it gets its info from a DHCP-server totally outisde of my control. I then have eth1,eth2,eth3 and eth4 which I have created a DHCP-server for.(ISC DHCP-Server) It seems to work, and I even get an IP-address from the foreign DHCP-server on the internet facing interface. However, for some reason it seems my gateway for eth0 became screwed after I installed my local DHCP-server for eth1-eth4. (I think so because I got an IP for eth0, and I can ping other stuff on the local network, but I cannot get access to the internet). My eth0-specific info in /etc/network/interfaces: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto eth1 iface eth1 inet static address 10.0.1.1 netmask 255.255.255.0 network 10.0.1.0 broadcast 10.0.1.255 gateway 10.0.1.1 mtu 8192 auto eth2 iface eth2 inet static address 10.0.2.1 netmask 255.255.255.0 network 10.0.2.0 broadcast 10.0.2.255 gateway 10.0.2.1 mtu 8192 My /etc/default/isc-dhcp-server: INTERFACES="eth1 eth2 eth3 eth4" So why does my local DHCP-server fuck up the gateway for eth0, when I tell it not to listen to eth0? Anyone see the problem or what I can do to fix it? The problem seems indeed to be the gateways. "netstat -nr" gives: 0.0.0.0 --- 10.X.X.X ---- 0.0.0.0 --- UG 0 0 0 eth3 It should have been 0.0.0.0 129.2XX.X.X 0.0.0.0 UG 0 0 0 eth0 So for some reason, my local DHCP-server overrides the gateway I get from the network DHCP. Edit: dhcp.conf looks like this(I included info only for eth1 subnet): ddns-update-style none; not authoritative; subnet 10.0.1.0 netmask 255.255.255.0 { interface eth1; option domain-name "example.org"; option domain-name-servers ns1.example.org, ns2.example.org; default-lease-time 600; max-lease-time 7200; range 10.0.1.10 10.0.1.100; host camera1_1 { hardware ethernet 00:30:53:11:24:6E; fixed-address 10.0.1.10; } host camera2_1 { hardware ethernet 00:30:53:10:16:70; fixed-address 10.0.1.11; } } Also, it seems that the gateway is correctly set if I run "/etc/init.d/networking restart" in a terminal, but that's not helpful for me, I need the correct gateway to be set during startup, and i'd rather find the source of the problem

• SQL SERVER – Sharing your ETL Resources Across Applications with Ease

  - by pinaldave

  Frequently an organization will find that the same resources are used in multiple ETL applications, for example, the same database, general purpose processing logic, or file system locations.  Creating an easy way to reuse these resources across multiple applications would increase efficiency and reduce errors.  Moreover, not every ETL developer has the same skill set, and it is likely that one developer will be more adept at writing code while another is more comfortable configuring database connections.  Real productivity gains will come when these developers are able to work independently while still making their work available to others assigned to the same project.  These are the benefits of a centralized version control system. Of course, most version control systems could be used to store and serve files, but the real need is to store and serve entire ETL applications so that each developer’s ongoing work can immediately benefit from another developer’s completed work.  In other words, the version control system needs to be tightly integrated with the tools used to develop the ETL application. The following screen shot shows such a tool. Desktop ETL tool that tightly integrates with a central version control system Developers can checkout or commit entire projects or just a single artifact.  Each artifact may be managed independently so if you need to go back to an earlier version of one artifact, changes you may have made to other artifacts are not lost.  By being tightly integrated into the graphical environment used to create and edit the project artifacts, it is extremely easy and straight-forward to move your files to and from the version control system and there is no dependency on another vendor’s version control system.  The built in version control system is optimized for managing the artifacts of ETL applications. It is equally important that the version control system supports all of the actions one typically performs such as rollbacks, locking and unlocking of files, and the ability to resolve conflicts.  Note that this particular ETL tool also has the capability to switch back and forth between multiple version control systems. It also needs to be easy to determine the status of an artifact.  Not just that it has been committed or modified, but when and by whom.  Generally you must query the version control system for this information, but having it displayed within the development environment is more desirable. Who’s ETL tool works in this fashion?  Last month I mentioned the data integration solution offered by expressor software.  The version control features I described in this post are all available in their just released expressor 3.1 Standard Edition through the integration of their expressor Studio development environment with a centralized metadata repository and version control system. You can download their Studio application, which is free, or evaluate the full Standard Edition on your own hardware.  It may be worth your time.

• What is hogging my connection?

  - by SF.

  At times it seems like dozens, if not hundreds of root-owned HTTP connections spring up. This is not much of a problem on LAN or WLAN as each of them seems to transfer very little, but if I use GPRS link, my ping times go into minutes (seriously, 80000ms is not infrequent!) and all connections grind to a halt waiting till these end.

• How to stream H264 Video from camera over FTP?

  - by Jay

  I bought a h264 security camera system last year and set it up to ftp video to my computer. I was able to get the video to play (even though it played a little fast) on Ubuntu 11.04 using mplayer. A few months ago, I did a fresh install of 12.04 and I cannot seem to get the video to play with mplayer, smplayer or VLC. I have the restricted formats video packages installed and when playing with any of the players, all I get is a gray video. When calling mplayer from the command line to play the video with no options, I get a lot of these errors: [h264 @ 0x7f278c61f280]concealing 1320 DC, 1320 AC, 1320 MV errors No pts value from demuxer to use for frame! pts after filters MISSING I'm not a video expert and have been coming up with a lot of dead ends when Googling for this. Could someone offer some advice about how to play these videos?

• Why does my MySQL remote-connection fail (VLAN)?

  - by Johannes Nielsen

  ubuntu-community! Again I have a problem with my special friend MySQL :D I have got two servers - a database-server and a web-server - who are connected via VLAN. Now I want the web-server to have remote access to the database-server's MySQL. So I created the user user in mysql.user. user's Host is xxx.yyy.zzz.9 which is the internal IP-address of the web-server. xxx.yyy.zzz.0 is the network. I also created user with Host % . As long as I use MySQL on the database-server logging in as user, everything works fine. But trying to log in as user from xxx.yyy.zzz.9 using mysql -h xxx.yyy.zzz.8 -u user -p (where xxx.yyy.zzz.8 is the database-server's internal IP), I get ERROR 2003 (HY000): Can't connect to MySQL server on 'xxx.yyy.zzz.8' (110) So I tried to activate Bind-Address in the my.cnf file. Well, if I use xxx.yyy.zzz.8, nothing changes. But if I try xxx.yyy.zzz.9 and try to restart MySQL, I get mysql stop/waiting start: Job failed to start I checked the log files and found - nothing. The database-server's MySQL doesn't even register, that the web-server tries to connect remotely. My idea is, that maybe I didn't configure the VLAN properley, even though I asked someone who actually knows such stuff and he told me, I did everything right. What I wrote into /etc/networking/interfaces is: #The VLAN auto eth1 iface eth1 inet static address xxx.yyy.zzz..8 netmask 255.255.255.0 network xxx.yyy.zzz.0 broadcast xxx.yyy.zzz.255 mtu 1500 ifconfig returns eth1 Link encap:Ethernet HWaddr xxxxxxxxxxxxxx inet addr:xxx.yyy.zzz.8 Bcast:xxx.yyy.zzz.255 Mask:255.255.255.0 inet6 addr: xxxxxxxxxxxxxxx/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:241146 errors:0 dropped:0 overruns:0 frame:0 TX packets:9765 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:17825995 (17.8 MB) TX bytes:566602 (566.6 KB) Memory:fb900000-fb920000 for the eth1, what is, what I configured. (This is for the database-server, the web-server looks similar). ethtool eth1 returns: Settings for eth1: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: on MDI-X: Unknown Supports Wake-on: d Wake-on: d Current message level: 0x00000003 (3) drv probe Link detected: yes (This is for the database-server, the web-server looks similar). Actually I think, everything is right, but it still doesn't work. Is there someone with an idea? EDIT: I commented ou Bind-Address in my.cnf after it didn't work.

• Algorithm for spreading labels in a visually appealing and intuitive way

  - by mac

  Short version Is there a design pattern for distributing vehicle labels in a non-overlapping fashion, placing them as close as possible to the vehicle they refer to? If not, is any of the method I suggest viable? How would you implement this yourself? Extended version In the game I'm writing I have a bird-eye vision of my airborne vehicles. I also have next to each of the vehicles a small label with key-data about the vehicle. This is an actual screenshot: Now, since the vehicles could be flying at different altitudes, their icons could overlap. However I would like to never have their labels overlapping (or a label from vehicle 'A' overlap the icon of vehicle 'B'). Currently, I can detect collisions between sprites and I simply push away the offending label in a direction opposite to the otherwise-overlapped sprite. This works in most situations, but when the airspace get crowded, the label can get pushed very far away from its vehicle, even if there was an alternate "smarter" alternative. For example I get: B - label A -----------label C - label where it would be better (= label closer to the vehicle) to get: B - label label - A C - label EDIT: It also has to be considered that beside the overlapping vehicles case, there might be other configurations in which vehicles'labels could overlap (the ASCII-art examples show for example three very close vehicles in which the label of A would overlap the icon of B and C). I have two ideas on how to improve the present situation, but before spending time implementing them, I thought to turn to the community for advice (after all it seems like a "common enough problem" that a design pattern for it could exist). For what it's worth, here's the two ideas I was thinking to: Slot-isation of label space In this scenario I would divide all the screen into "slots" for the labels. Then, each vehicle would always have its label placed in the closest empty one (empty = no other sprites at that location. Spiralling search From the location of the vehicle on the screen, I would try to place the label at increasing angles and then at increasing radiuses, until a non-overlapping location is found. Something down the line of: try 0°, 10px try 10°, 10px try 20°, 10px ... try 350°, 10px try 0°, 20px try 10°, 20px ...

• Interpolation using a sprite's previous frame and current frame

  - by user22241

  Overview I'm currently using a method which has been pointed out to me is extrapolation rather than interolation. As a result, I'm also now looking into the possibility of using another method which is based on a sprite's position at it's last (rendered) frame and it's current one. Assuming an interpolation value of 0.5 this is, (visually), how I understand it should affect my sprite's position.... This is how I'm obtaining an inerpolation value: public void onDrawFrame(GL10 gl) { // Set/re-set loop back to 0 to start counting again loops=0; while(System.currentTimeMillis() > nextGameTick && loops < maxFrameskip) { SceneManager.getInstance().getCurrentScene().updateLogic(); nextGameTick += skipTicks; timeCorrection += (1000d / ticksPerSecond) % 1; nextGameTick += timeCorrection; timeCorrection %= 1; loops++; tics++; } interpolation = (float)(System.currentTimeMillis() + skipTicks - nextGameTick) / (float)skipTicks; render(interpolation); } I am then applying it like so (in my rendering call): render(float interpolation) { spriteScreenX = (spriteScreenX - spritePreviousX) * interpolation + spritePreviousX; spritePreviousX = spriteScreenX; // update and store this for next time } Results This unfortunately does nothing to smooth the movement of my sprite. It's pretty much the same as without the interpolation code. I can't get my head around how this is supposed to work and I honestly can't find any decent resources which explain this in any detail. My understanding of extrapolation is that when we arrive at the rendering call, we calculate the time between the last update call and the render call, and then adjust the sprite's position to reflect this time (moving the sprite forward) - And yet, this (Interpolation) is moving the sprite back, so how can this produce smooth results? Any advise on this would be very much appreciated. Edit I've implemented the code from OriginalDaemon's answer like so: @Override public void onDrawFrame(GL10 gl) { newTime = System.currentTimeMillis()*0.001; frameTime = newTime - currentTime; if ( frameTime > (dt*25)) frameTime = (dt*25); currentTime = newTime; accumulator += frameTime; while ( accumulator >= dt ) { SceneManager.getInstance().getCurrentScene().updateLogic(); previousState = currentState; t += dt; accumulator -= dt; } interpolation = (float) (accumulator / dt); render(); } Interpolation values are now being produced between 0 and 1 as expected (similar to how they were in my original loop) - however, the results are the same as my original loop (my original loop allowed frames to skip if they took too long to draw which I think this loop is also doing). I appear to have made a mistake in my previous logging, it is logging as I would expect it to (interpolated position does appear to be inbetween the previous and current positions) - however, the sprites are most definitely choppy when the render() skipping happens.

• Tuning Red Gate: #3 of Lots

  - by Grant Fritchey

  I'm drilling down into the metrics about SQL Server itself available to me in the Analysis tab of SQL Monitor to see what's up with our two problematic servers. In the previous post I'd noticed that rg-sql01 had quite a few CPU spikes. So one of the first things I want to check there is how much CPU is getting used by SQL Server itself. It's possible we're looking at some other process using up all the CPU Nope, It's SQL Server. I compared this to the rg-sql02 server: You can see that there is a more, consistently low set of CPU counters there. I clearly need to look at rg-sql01 and capture more specific data around the queries running on it to identify which ones are causing these CPU spikes. I always like to look at the Batch Requests/sec on a server, not because it's an indication of a problem, but because it gives you some idea of the load. Just how much is this server getting hit? Here are rg-sql01 and rg-sql02: Of the two, clearly rg-sql01 has a lot of activity. Remember though, that's all this is a measure of, activity. It doesn't suggest anything other than what it says, the number of requests coming in. But it's the kind of thing you want to know in order to understand how the system is used. Are you seeing a correlation between the number of requests and the CPU usage, or a reverse correlation, the number of requests drops as the CPU spikes? See, it's useful. Some of the details you can look at are Compilations/sec, Compilations/Batch and Recompilations/sec. These give you some idea of how the cache is getting used within the system. None of these showed anything interesting on either server. One metric that I like (even though I know it can be controversial) is the Page Life Expectancy. On the average server I expect see a series of mountains as the PLE climbs then drops due to a data load or something along those lines. That's not the case here: Those spikes back in January suggest that the servers weren't really being used much. The PLE on the rg-sql01 seems to be somewhat consistent growing to 3 hours or so then dropping, but the rg-sql02 PLE looks like it might be all over the map. Instead of continuing to look at this high level gathering data view, I'm going to drill down on rg-sql02 and see what it's done for the last week: And now we begin to see where we might have an issue. Memory on this system is getting flushed every 1/2 hour or so. I'm going to check another metric, scans: Whoa! I'm going back to the system real quick to look at some disk information again for rg-sql02. Here is the average disk queue length on the server: and the transfers Right, I think I have a guess as to what's up here. We're seeing memory get flushed constantly and we're seeing lots of scans. The disks are queuing, especially that F drive, and there are lots of requests that correspond to the scans and the memory flushes. In short, we've got queries that are scanning the data, a lot, so we either have bad queries or bad indexes. I'm going back to the server overview for rg-sql02 and check the Top 10 expensive queries. I'm modifying it to show me the last 3 days and the totals, so I'm not looking at some maintenance routine that ran 10 minutes ago and is skewing the results: OK. I need to look into these queries that are getting executed this much. They're generating a lot of reads, but which queries are generating the most reads: Ow, all still going against the same database. This is where I'm going to temporarily leave SQL Monitor. What I want to do is connect up to the server, validate that the Warehouse database is using the F:\ drive (which I'll put money down it is) and then start seeing what's up with these queries.

• How do I deal with a third party application that has embedded hints that result in a sub-optimal execution plan in my environment?

  - by Maria Colgan

  I have gotten many variations on this question recently as folks begin to upgrade to Oracle Database 11g and there have been several posts on this blog and on others describing how to use SQL Plan Management (SPM) so that a non-hinted SQL statement can use a plan generated with hints. But what if the hint is supplied in the third party application and is causing performance regressions on your system? You can actually use a very similar technique to the ones shown before but this time capture the un-hinted plan and have the hinted SQL statement use that plan instead. Below is an example that demonstrates the necessary steps. 1. We will begin by running the hinted statement 2. After examining the execution plan we can see it is suboptimal because of a bad join order. 3. In order to use SPM to correct the problem we must create a SQL plan baseline for the statement. In order to create a baseline we will need the SQL_ID for the hinted statement. Easy place to get it is in V$SQL. 4. A SQL plan baseline can be created using a SQL_ID and DBMS_SPM.LOAD_PLANS_FROM_CURSOR_CACHE. This will capture the existing plan for this SQL_ID from the shared pool and store in the SQL plan baseline. 5. We can check the SQL plan baseline got created successfully by querying DBA_SQL_PLAN_BASELINES. 6. When you manually create a SQL plan baseline the first plan added is automatically accepted and enabled. We know that the hinted plan is poorly performing plan so we will disable it using DBMS_SPM.ALTER_SQL_PLAN_BASELINE. Disabling the plan tells the optimizer that this plan not a good plan, however since there is no alternative plan at this point the optimizer will still continue to use this plan until we provide a better one. 7. Now let's run the statement without the hint. 8. Looking at the execution plan we can see that the join order is different. The plan without the hint also has a lower cost (3X lower), which indicates it should perform better. 9. In order to map the un-hinted plan to the hinted SQL statement we need to add the plan to the SQL plan baseline for the hinted statement. We can do this using DBMS_SPM.LOAD_PLANS_FROM_CURSOR_CACHE but we will need the SQL_ID and  PLAN_HASH_VALUE for the non-hinted statement, which we can find in V$SQL. 10. Now we can add the non-hinted plan to the SQL plan baseline of the hinted SQL statement using DBMS_SPM.LOAD_PLANS_FROM_CURSOR_CACHE. This time we need to pass a few more arguments. We will use the SQL_ID and PLAN_HASH_VALUE of the non-hinted statement but the SQL_HANDLE of the hinted statement. 11. The SQL plan baseline for our statement now has two plans. But only the newly added plan (SQL_PLAN_gbpcg3f67pc788a6d8911) is enabled and accepted. This tells the Optimizer that this is the plan it should use for this statement. We can confirm that the correct plan (non-hinted) will be selected for the statement from now on by re-executing the hinted statement and checking its execution plan.

• Remove the Lock Icon from a Folder in Windows 7

  - by Trevor Bekolay

  If you’ve been playing around with folder sharing or security options, then you might have ended up with an unsightly lock icon on a folder. We’ll show you how to get rid of that icon without over-sharing it. The lock icon in Windows 7 indicates that the file or folder can only be accessed by you, and not any other user on your computer. If this is desired, then the lock icon is a good way to ensure that those settings are in place. If this isn’t your intention, then it’s an eyesore. To remove the lock icon, we have to change the security settings on the folder to allow the Users group to, at the very least, read from the folder. Right-click on the folder with the lock icon and select Properties. Switch to the Security tab, and then press the Edit… button. A list of groups and users that have access to the folder appears. Missing from the list will be the “Users” group. Click the Add… button. The next window is a bit confusing, but all you need to do is enter “Users” into the text field near the bottom of the window. Click the Check Names button. “Users” will change to the location of the Users group on your particular computer. In our case, this is PHOENIX\Users (PHOENIX is the name of our test machine). Click OK. The Users group should now appear in the list of Groups and Users with access to the folder. You can modify the specific permissions that the Users group has if you’d like – at the minimum, it must have Read access. Click OK. Keep clicking OK until you’re back at the Explorer window. You should now see that the lock icon is gone from your folder! It may be a small aesthetic nuance, but having that one folder stick out in a group of other folders is needlessly distracting. Fortunately, the fix is quick and easy, and does not compromise the security of the folder!

• How to replace the SharePoint date calendar control with more user friendly jQuery calendar control

  - by ybbest

  When you use the SharePoint date and time type for date of birth field, you will notice that the calendar control is extremely non-user-friendly. You can only navigate month by month as shown below. To resolve the issue, you can customize the list form page using SharePoint designer and replace the OOB calendar control with popular jQuery control. The solution works for both SharePoint 2010,2013 and office365. Here are the steps for how to achieve this. 1. Open SharePoint designer and create a New List Form called customNew and set as default form for the selected type. 2. Open style library in file explorer and copy jQuery and jQuery UI files into the style library in SharePoint site. You can download the jQuery and jQuery UI from the web and the content of the contactPersonCustomNewForm.js is as below. I use the dd/mm/yy format as my locale in Regional Settings is English(New Zealand). You need to change this if you live in another country with different date format $(document).ready(function() { $("img#ctl00_m_g_540b9a50_52dc_4400_a58d_1db99555fddf_ff41_ctl00_ctl00_DateTimeField_DateTimeFieldDateDatePickerImage").parent().hide(); $("img#ctl00_m_g_540b9a50_52dc_4400_a58d_1db99555fddf_ff41_ctl00_ctl00_DateTimeField_DateTimeFieldDateDatePickerImage").hide(); $("input#ctl00_m_g_540b9a50_52dc_4400_a58d_1db99555fddf_ff41_ctl00_ctl00_DateTimeField_DateTimeFieldDate").datepicker({ changeMonth:true, changeYear:true, showOn: "button", buttonImage: "/_layouts/images/calendar.gif", buttonImageOnly: true, defaultDate:"01/01/1970", yearRange: "c-20:c+20", dateFormat: "dd/mm/yy" }); }); In order to get the image and textbox selector above , you can open IE developer toolbar(click F12) and find the control ID as below: 3. Open SharePoint designer and edit the newly created New List Form customNew.aspx in advance mode. Then copy and paste the following links in the PlaceHolderAdditionalPageHead. <SharePoint:CssRegistration name="<%$SPUrl:~SiteCollection/Style Library/themes/ui-lightness/jquery-ui.css%>" runat="server"/> <SharePoint:ScriptLink language="javascript" name="~sitecollection/Style Library/jquery-1.10.2.js" Defer="false" runat="server"/> <SharePoint:ScriptLink language="javascript" name="~sitecollection/Style Library/jquery-ui-1.10.4.custom.min.js" Defer="false" runat="server"/> <SharePoint:ScriptLink language="javascript" name="~sitecollection/Style Library/contactPersonCustomNewForm.js" Defer="false" runat="server"/>   4. Now go to the list and click add, you will see the new calendar control as shown below

• Best development architecture for a small team of programmers ( WAMP Stack )

  - by Tio

  Hi all.. I'm in the first month of work in a new company.. and after I met the two programmer's and asked how things are organized in terms of projects inside the company, they simply shrug their shoulders, and said that nothing is organized.. I think my jaw hit the ground that same time.. ( I know some, of you think I should quit, but I'm on a privileged position, I'm the most experienced there, so there's room for me to grow inside the company, and I'm taking the high road ).. So I talked to the IT guy, and one of the programmers, and maybe this week I'm going to get a server all to myself to start organizing things. I've used various architectures in my previous work experiences, on one I was developing in a server on the network ( no source control of course ).. another experience I had was developing in my local computer, with no server on the network, just source control. And at home, I have a mix of the two, everything I code is on a server on the network, and I have those folders under source control, and I also have a no-ip account configured on that server so I can access it everywhere and I can show the clients anything. For me I think this last solution ( the one I have at home ) is the best: Network server with WAMP stack. The server as a public IP so we can access it by domain name. And use subdomains for each project. Everybody works directly on the network server. I think the problem arises, when two or more people want to work on the same project, in this case the only way to do this is by using source control and local repositories, this is great, but I think this turns development a lot more complicated. In the example I gave, to make a change to the code, I would simply need to open the file in my favorite editor, make the change, alter the database, check in the changes into source control and presto all done. Using local repositories, I would have to get the latest version, run the scripts on the local database to update it, alter the file, alter the database, check in the changes to the network server, update the database on the network server, see if everything is running well on the network server, and presto all done, to me this seems overcomplicated for a change on a simple php page. I could share the database for the local development and for the network server, that sure would help. Maybe the best way to do this is just simply: Network server with WAMP stack ( test server so to speak ), public server accessible trough the web. LAMP stack on every developer computer ( minus the database ) We develop locally, test, then check in the changes into the server test and presto. What do you think? Maybe I should start doing this at home.. Thanks and best regards... Edit: I'm sorry I made a mistake and switched WAMP with LAMP, sorry about that..

• Apache2 "pseudo" doc root

  - by Brent

  I have several folders in my /www folder that contain various applications. To keep things organized, I keep them in their own folders -- this includes my base application. Examples: phpmyadmin = /www/phpmyadmin phpvirtualbox = /www/phpvirtualbox root domain site = /www/Landing The reason I segregate all of my sites is that I actively develop on some of these (my root site) and when I publish via Visual Studio, I choose to delete prior to upload - if I put the Landing page in the base folder, it would be devastating for me. My goal is that when I go to www.example.com - I go to my page. If I go to www.example.com/phpmyadmin, it does not work because of this in the Apache2 folder: <Location "/"> # Error is the "/" Allow from all Order allow,deny MonoSetServerAlias domain SetHandler mono SetOutputFilter DEFLATE SetEnvIfNoCase Request_URI "\.(?:gif|jpe?g|png)$" no-gzip dont-vary </Location> <IfModule mod_deflate.c> AddOutputFilterByType DEFLATE text/html text/plain text/xml text/javascript </IfModule> If I change the location to say "/Other", then the base site is broken, and the aliases are restored for the other sites. If it is "/", then the base site works and no aliases work. What could I do to allow it to treat my /www/Landing as my webroot, but when I go to an alias, it GOES to the alias.

• Live CD / Live USB much faster than full install

  - by user29347

  I've observed it on both laptops I own! HP Compaq nx6125 and Ubuntu 11.04 x64 - somewhat solved Lenovo Thinkpad T500 and Ubuntu 11.10 x64 - help needed! I'm still struggling with the Thinkpad to get performance level similar to that of 10 y.o. laptops... All in all a really serious issue with multiple versions of Ubuntu that renders computers with perfectly compatible hardware unusable, as far as out of the box experience is concerned. Troubleshooting resultant issues seems to be a hard case even for users with some experience with installing graphics drivers. EDIT: I can't really post additional details. Two different ubuntu versions, two laptops, two different set of graph. drivers (OS vs ATI prop.) - all with the same symptoms. Also I can't stress enough how massive the performance degradation is compared to a healthy system. For that reason I ask for input from people who may know roughly what are we dealing with here. I can post more details if we were to focus on my current Thinkpad T500. In that case my current system details: Lenovo Thinkpad T500 Ubuntu 11.10 x64 ATI Mobility Radeon HD 3650 (also see the "What I have already tried" section about Intel graphics tested) ATI Catalyst 11.10 drivers OCZ Agility 3 SSD but! same with the default driver for ATI the card same with the prop. driver for the ATI card from Jockey (Additional drivers applet) What I have already tried: 0. Switching to Intel integrated card (Intel GMA 4500M HD) with the default driver - same effects = may indicate not driver related problem but a problem with something of global influence like e.g. nomodeset or other I don't even know about. (What you can read above) ATI Catalyst 11.10 and radeon.modeset=0 boot parameter + disabled Wait for VBlank. Unity 2D Ubuntu 10.04 LTS tested (ubuntu-10.04.3-desktop-i386.iso): Both live USB and installed version blazing fast! (on the default drivers - without even installing the proprietary fglrx drivers). re2 a) seems to give me the only significant results (still poor) - perfect Unity elements performance with the same crawling stuttering/lagging when dragging windows around. re2 b) this happens often http://i17.photobucket.com/albums/b68/Bucic/ubuntuforumsorg/Screenshotat2011-10-28083140.png re2 c) Sometimes I am able to witness a normal performance when dragging a window around but only for a second or two. When I try to shake it longer it starts to lag and it will keep lagging like that with an increased probability of what you see in the sshot in point re2 b). re2 d) I can't establish the radeon.modeset=0 influence though. Once it seems to work be smooth with it, the other time - without it. Really can't tell.

• How to repair an external harddrive?

  - by dodohjk

  I would like to reformat my hard disk, and if possible recover the (somewhat unimportant) contents if possible. I have a Western Digital 1TB hard drive which had a NTFS partition. I unplugged the drive without safely removing it first. At first a pop up was asking me to use a Windows OS to run the chkdsk /f command, however, in the effort to keep using a Linux OS I used the ntfsfix command on the ubuntu terminal Now, when I try to access the hard drive, it doesn't show up anymore in Nautilus. I tried reformatting it using Disk Utility, but it gives me an error message, and Gparted would hang on the "Scanning devices" step infinitely. Please comment any output that you would like to see and I will add it to my question. EDIT disk utility tells me is on /dev/sdb the command sudo fdisk -l gives dodohjk@DodosPC:~$ sudo fdisk -l [sudo] password for dodohjk: Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders, total 488397168 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: 0x0006fa8c Device Boot Start End Blocks Id System /dev/sda1 * 4094 482344959 241170433 5 Extended /dev/sda2 482344960 488396799 3025920 82 Linux swap / Solaris /dev/sda5 4096 31461127 15728516 83 Linux /dev/sda6 31463424 52434943 10485760 83 Linux /dev/sda7 52436992 62923320 5243164+ 83 Linux /dev/sda8 62924800 482344959 209710080 83 Linux Disk /dev/sdb: 1000.2 GB, 1000202043392 bytes 255 heads, 63 sectors/track, 121600 cylinders, total 1953519616 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: 0x6e697373 This doesn't look like a partition table Probably you selected the wrong device.

If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device&gt;

  Installing Oracle Event Processing 11g Earlier this month I was involved in organizing the Monument Family History Day.  It was certainly a complex event, with dozens of presenters, guides and 100s of visitors.  So with that experience of a complex event under my belt I decided to refresh my acquaintance with Oracle Event Processing (CEP). CEP has a developer side based on Eclipse and a runtime environment. Developer Install The developer install requires several steps (documentation) Download required software Eclipse  (Linux) – It is recommended to use version 3.6.2 (Helios) Install Eclipse Unzip the download into the desired directory Start Eclipse Add Oracle CEP Repository in Eclipse http://download.oracle.com/technology/software/cep-ide/11/ Install Oracle CEP Tools for Eclipse 3.6 You may need to set the proxy if behind a firewall. Modify eclipse.ini If using Windows edit with wordpad rather than notepad Point to 1.6 JVM Insert following lines before –vmargs -vm \PATH_TO_1.6_JDK\jre\bin\javaw.exe Increase PermGen Memory Insert following line at end of file -XX:MaxPermSize=256M Restart eclipse and verify that everything is installed as expected. Server install The server install is very straightforward (documentation).  It is recommended to use the JRockit JDK with CEP so the steps to set up a working CEP server environment are: Download required software JRockit – I used Oracle “JRockit 6 - R28.2.5” which includes “JRockit Mission Control 4.1” and “JRockit Real Time 4.1”. Oracle Event Processor – I used “Complex Event Processing Release 11gR1 (11.1.1.6.0)” Install JRockit Run the JRockit installer, the download is an executable binary that just needs to be marked as executable. Install CEP Unzip the downloaded file Run the CEP installer,  the unzipped file is an executable binary that may need to be marked as executable. Choose a custom install and add the examples if needed. It is not recommended to add the examples to a production environment but they can be helpful in development. Voila The Deed Is Done With CEP installed you are now ready to start a server, if you didn’t install the demoes then you will need to create a domain before starting the server. Once the server is up and running (using startwlevs.sh) you can verify that the visualizer is available on http://hostname:port/wlevs, the default port for the demo domain is 9002. With the server running you can test the IDE by creating a new “Oracle CEP Application Project” and creating a new target environment pointing at your CEP installation. Much easier than organizing a Family History Day!
