• What do neglected O'Reilly book topics tell us about that topic?

  - by Peter Turner

  Does anybody know how O'Reilly chooses topics to publish? For some reason, I don't see how it can be based on demand. The reason, I ask, is because they haven't published a Delphi book in almost 12 years and Object Pascal is at least as esoteric as Erlang and as practical as PHP and as robust as C++. So, maybe someone knows what rationale is behind O'Reilly's publishing methodology or what it is supposed to tell us about the relative popularity or usefulness of any given language or programming technique? Oh, I forgot about pig and robotlegs

• How to sync tasks between Ubuntu and Android?

  - by andrewsomething

  I was using first Tasque and then GTG on Ubuntu and Astrid on Android with Remember The Milk as the backend. Recently, Astrid has dropped support for Remember The Milk, and both Tasque and GTG's support for syncing with RTM has always left something to be desired. So I'm looking for a new solution, and I'm open to leaving RTM especially if it is for something that isn't proprietary. What have you found to keep your tasks lists in-sync between Ubuntu and Android? In particular, I'm looking for a desktop based program on the Ubuntu side rather than something in the browser. Astrid has treated me well, but I wouldn't mind trying something else. Currently, it can sync with Astrid.com, Google Tasks, and Producteev. Anyone know of a desktop app that supports any of those?

• References about Game Engine Architecture in AAA Games

  - by sharethis

  Last weeks I focused on game engine architecture and learned a lot about different approaches like component based, data driven, and so on. I used them in test applications and understand their intention but none of them looks like the holy grail. So I wonder how major games in the industry ("AAA Games") solve different architecture problems. But I noticed that there are barely references about game engine architecture out there. Do you know any resources of game engine architecture of major game titles like Battlefield, Call of Duty, Crysis, Skyrim, and so on? Doesn't matter if it is an article of a game developer or a wiki page or an entire book. I read this related popular question: Good resources for learning about game architecture? But it is focused on learning books rather than approaches in the industry. Hopefully the breadth of our community can carry together certain useful informations! Thanks a lot! Edit: This question is focused but not restricted to first person games.

• How to create a "shutdown user" or "shutdown account"

  - by pcapademic

  Red Hat had a feature useful to me at the present time. There was an account, generally called "shutdown", and when you logged in with the account, the system shut down. In my specific case, I have Ubuntu Server running in a VM on my local system. The VM is running a web app, and when I'm done doing work, I want to shut down the VM. Unfortunately, I can't install VMware tools to get the "power button" based shutdown. Currently I login then sudo shutdown -h now, then type my password again, and things shutdown. Really, it's getting annoying all that waiting around and typing things. How do I replicate the "shutdown account" functionality in Ubuntu? A related question, were there any security gotchas that motivated people to stop using this kind of account?

• Rsync Push files from linux to windoes. ssh issue - connection refused

  - by piyush c

  For some reason I want to run a script to move files from Linux machine to Windows. I have installed cwRsync on my windows machine and able to connect to linux machine. When i execute following command: rsync -e "ssh -l "piyush"" -Wgovz --timeout 120 --delay-updates --remove-sent-files /usr/local/src/piyush/sync/* "[email protected]:/cygdrive/d/temp" Where 10.0.0.60 is my widows machine and I am running above command on Linux - CentOS 5.5. After running command I get following error message: ssh: connect to host 10.0.0.60 port 22: Connection refused rsync: connection unexpectedly closed (0 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at io.c(463) [sender=2.6.8] [root@localhost sync]# ssh [email protected] ssh: connect to host 10.0.0.60 port 22: Connection refused I have modified my firewall settings on widows to allow all ports. I think this issue is due to SSH Daemon not present on my windows machine. So I tried installing OpenSSH on my machine and running ssh-agent but didn't helped. I tried similar command to run on my widows machine to pull files from Linux and its working fine. For some reason I want command for Linux machine so that I can embed it in a shell script. Can you suggest me if I am missing anything. I am already having cwRsync installed on my widows and running it in daemon mode using --damemon option. And I am able to login using ssh from windows machine to linux machine. When I issue bellow command, it just blocks for 120 seconds (timeout I specified in command) and exits saying there is timeout. rsync -e "ssh -l piyush" -Wgovz --timeout 120 --delay-updates --remove-sent-files /usr/local/src/piyush/sync/* "[email protected]:/cygdrive/d/temp" After starting rsync on widows, I checked, rsyc is running. And widows firewall setting are set to minimal, and on Linux machine stopped iptables service so that port 873 (default rsync port) is not blocked. What can be the possible reason that Linux machine is not able to connect to rsync-daemon on windows machine?

• Not so long ago in a city not so far away by Carlos Martin

  - by Maria Sandu

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 This is the story of how the EMEA Presales Center turned an Oracle intern into a trusted technology advisor for both Oracle’s Sales and customers. It was the summer of 2011 when I was finishing my Computer Engineering studies as well as my internship at Oracle when I was offered what could possibly be THE dream job for any young European Computer Engineer. Apart from that, it also seemed like the role was particularly tailored to me as I could leverage almost everything I learned at University and during the internship. And all of it in one of the best cities to live in, not only from my home country but arguably from Europe: Malaga! A day at EPC As part of the EPC Technology pillar, and later on completely focused on WebCenter, there was no way to describe a normal day on the job as each day had something unique. Some days I was researching documentation in order to elaborate accurate answers for a customer’s question within a Request for Information or Proposal (RFI/RFP), other days I was doing heavy programming in order to bring a Proof of Concept (PoC) for a customer to life and last not but least, some days I presented to the customer via webconference the demo I built for them the past weeks. So as you can see, the role has research, development and presentation, could you ask for more? Well, don’t worry because there IS more! Internationality As the organization’s name suggests, EMEA Presales Center, it is the Center of Presales within Europe, Middle East and Africa so I got the chance to work with great professionals from all this regions, expanding my network and learning things from one country to apply them to others. In addition to that, the teams based in the Malaga office are comprised of many young professionals hailing mainly from Western and Central European countries (although there are a couple of exceptions!) with very different backgrounds and personalities which guaranteed many laughs and stories during lunch or coffee breaks (or even while working on projects!). Furthermore, having EPC offices in Bucharest and Bangalore and thanks to today’s tele-presence technologies, I was working every day with people from India or Romania as if they were sitting right next to me and the bonding with them got stronger day by day. Career development Apart from the research and self-study I’ve earlier mentioned, one of the EPC’s Key Performance Indicators (KPI) is that 15% of your time is spent on training so you get lots and lots of trainings in order to develop both your technical product knowledge and your presentation, negotiation and other soft skills. Sometimes the training is via webcast, sometimes the trainer comes to the office and sometimes, the best times, you get to travel abroad in order to attend a training, which also helps you to further develop your network by meeting face to face with many people you only know from some email or instant messaging interaction. And as the months go by, your skills improving at a very fast pace, your relevance increasing with each new project you successfully deliver, it’s only a matter of time (and a bit of self-promoting!) that you get the attention of the manager of a more senior team and are offered the opportunity to take a new step in your professional career. For me it took 2 years to move to my current position, Technology Sales Consultant at the Oracle Direct organization. During those 2 years I had built a good relationship with the Oracle Direct Spanish sales and sales managers, who are also based in the Malaga office. I supported their former Sales Consultant in a couple of presentations and demos and were very happy with my overall performance and attitude so even before the position got eventually vacant, I got a heads-up from then in advance that their current Sales Consultant was going to move to a different position. To me it felt like a natural step, same as when I joined EPC, I had at least a 50% of the “homework” already done but wanted to experience that extra 50% to add new product and soft skills to my arsenal. The rest is history, I’ve been in the role for more than half a year as I’m writing this, achieved already some important wins, gained a lot of trust and confidence in front of customers and broadened my view of Oracle’s Fusion Middleware portfolio. I look back at the 2 years I spent in EPC and think: “boy, I’d recommend that experience to absolutely anyone with the slightest interest in IT, there are so many different things you can do as there are different kind of roles you can end up taking thanks to the experience gained at EPC” /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

• What must be done to allow a development team to minimize difficulties as new team members are added?

  - by Travis

  I work at a small Web Dev firm, and have been handling all the PHP/MySQL/etc. for a while. I'm looking at improving our practices to allow for easier collaboration as we grow. Some things I have in mind are: Implementing a versioning system (source control) Coding standards for the team (unless mandated by a certain framework, etc.) Enforcing a common directory structure for our Desktops (for backup purposes, etc.) Web-based task/project/time/file/password/contact management and collaboration app(we've tried a bunch; I may just create one) What do more experienced developers view as necessary first steps in this area? Do you recommend any books? One thing to consider is that the bulk of our daily tasks involve maintenance and adding minor functionality rather than new projects, and the team size will be between 3 and 5. I just found a related question about teams that will be expanding from a solo developer.

• Vserver: secure mails from a hacked webservice

  - by lukas

  I plan to rent and setup a vServer with Debian xor CentOS. I know from my host, that the vServers are virtualized with linux-vserver. Assume there is a lighthttpd and some mail transfer agent running and we have to assure that if the lighthttpd will be hacked, the stored e-mails are not readable easily. For me, this sounds impossible but may I missed something or at least you guys can validate the impossibility... :) I think basically there are three obvious approaches. The first is to encrypt all the data. Nevertheless, the server would have to store the key somewhere so an attacker (w|c)ould figure that out. Secondly one could isolate the critical services like lighthttpd. Since I am not allowed to do 'mknod' or remount /dev in a linux-vserver, it is not possible to setup a nested vServer with lxc or similar techniques. The last approach would be to do a chroot but I am not sure if it would provide enough security. Further I have not tried yet, if I am able to do a chroot in a linux-vserver...? Thanks in advance!

• How to render axometric/isometric tiles that are a 2d array in logic, but inclined 45º visually?

  - by TheLima

  I am making a tile-based strategy game which i plan to have 2.5D visuals in an axometric/isometric fashion. Right now i'm programming it's logic and rendering it as a literal 2-dimensional array (perfect squares, like an isometric top-down-view). In short, i have something like this: And i want to turn it to something like this: Do i keep going on the 2d-array logic? Is it all just a change in rendering behavior, as i'm thinking it is? or 2d-array is the wrong approach for my objective and I should change before it's too late? What are the ways of doing it, anyways? How should i apply the 2.5D axometric/isometric view (45º rotation to the side, and 45º rotation upwards)?

• Url Navigation

  - by russ.bishop

  One of the new features is URL-based navigation which is useful for creating intranet links or auto-generating email links (such as from workflow systems, etc). For IIS 6 and earlier, the format is as follows: http://machine/drm-client/Logon.aspx? app=<appname>&action=go&ver=<version name>&hier=<hier name>&node=<node name> Just replace the fields with their appropriate values (URL-encoded of course). <node name> is optional. If provided it will open the hierarchy and expand directly to the target node. Otherwise the hierarchy is opened to the top node. Note that if the specified version is not loaded it will be loaded automatically.

• Ubuntu tweak and Mozilla (firefox and thunderbird) cache

  - by Avatar Parto

  I usually use Ubuntu tweak to do cleanup jobs on my PC. This includes apt and program cached data and old kernels. This goes alright for most programs except Mozilla based application - Firefox and Thunderbird. Ubuntu tweak doesn't seem to know where their cache folders are and always returns 'zero packages can be cleaned' even when the cache folder is full. Check screenshot below: I am looking for a way to clean up ALL my cache data and unneeded packages at one point. If someone knows how to change the ubuntu tweak cache folders for Firefox and Thunderbird, that would be perfect. I tried bleachbit last but it crashed my PC to a point I had to re-install Ubuntu. I am using Ubuntu tweak 0.8.6 on Ubuntu 13.04. Thanxs.

• 'Development dashboard' web application

  - by espais

  Hi all, I am not sure if something like this exists in that it is ready out of the box. I currently have some web space that I use for various projects, and I would like to setup an area for some friends and I to develop web applications together. My ideal setup would be to create a folder, say, webdev.domain.com. We could all go to this domain, login, and then be able to setup new applications, pick which language will be used, setup database tables, allow HTML based file uploading, and create sub-folders to basically have a test bed for the applications. In retrospect, it seems like I'm describing a limited version of cpanel. I could come up with something in Drupal I'm sure, but I don't want to have to really spend time configuring much. Like I said, I want to install it and have minimal configuration. Does something like this exist (preferably in open-source)?

• SQL SERVER – SSMS: Top Object and Batch Execution Statistics Reports

  - by Pinal Dave

  The month of June till mid of July has been the fever of sports. First, it was Wimbledon Tennis and then the Soccer fever was all over. There is a huge number of fan followers and it is great to see the level at which people sometimes worship these sports. Being an Indian, I cannot forget to mention the India tour of England later part of July. Following these sports and as the events unfold to the finals, there are a number of ways the statisticians can slice and dice the numbers. Cue from soccer I can surely say there is a team performance against another team and then there is individual member fairs against a particular opponent. Such statistics give us a fair idea to how a team in the past or in the recent past has fared against each other, head-to-head stats during World cup and during other neutral venue games. All these statistics are just pointers. In reality, they don’t reflect the calibre of the current team because the individuals who performed in each of these games are totally different (Typical example being the Brazil Vs Germany semi-final match in FIFA 2014). So at times these numbers are misleading. It is worth investigating and get the next level information. Similar to these statistics, SQL Server Management studio is also equipped with a number of reports like a) Object Execution Statistics report and b) Batch Execution Statistics reports. As discussed in the example, the team scorecard is like the Batch Execution statistics and individual stats is like Object Level statistics. The analogy can be taken only this far, trust me there is no correlation between SQL Server functioning and playing sports – It is like I think about diet all the time except while I am eating. Performance – Batch Execution Statistics Let us view the first report which can be invoked from Server Node -> Reports -> Standard Reports -> Performance – Batch Execution Statistics. Most of the values that are displayed in this report come from the DMVs sys.dm_exec_query_stats and sys.dm_exec_sql_text(sql_handle). This report contains 3 distinctive sections as outline below.   Section 1: This is a graphical bar graph representation of Average CPU Time, Average Logical reads and Average Logical Writes for individual batches. The Batch numbers are indicative and the details of individual batch is available in section 3 (detailed below). Section 2: This represents a Pie chart of all the batches by Total CPU Time (%) and Total Logical IO (%) by batches. This graphical representation tells us which batch consumed the highest CPU and IO since the server started, provided plan is available in the cache. Section 3: This is the section where we can find the SQL statements associated with each of the batch Numbers. This also gives us the details of Average CPU / Average Logical Reads and Average Logical Writes in the system for the given batch with object details. Expanding the rows, I will also get the # Executions and # Plans Generated for each of the queries. Performance – Object Execution Statistics The second report worth a look is Object Execution statistics. This is a similar report as the previous but turned on its head by SQL Server Objects. The report has 3 areas to look as above. Section 1 gives the Average CPU, Average IO bar charts for specific objects. The section 2 is a graphical representation of Total CPU by objects and Total Logical IO by objects. The final section details the various objects in detail with the Avg. CPU, IO and other details which are self-explanatory. At a high-level both the reports are based on queries on two DMVs (sys.dm_exec_query_stats and sys.dm_exec_sql_text) and it builds values based on calculations using columns in them: SELECT * FROM    sys.dm_exec_query_stats s1 CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS s2 WHERE   s2.objectid IS NOT NULL AND DB_NAME(s2.dbid) IS NOT NULL ORDER BY  s1.sql_handle; This is one of the simplest form of reports and in future blogs we will look at more complex reports. I truly hope that these reports can give DBAs and developers a hint about what is the possible performance tuning area. As a closing point I must emphasize that all above reports pick up data from the plan cache. If a particular query has consumed a lot of resources earlier, but plan is not available in the cache, none of the above reports would show that bad query.

• Browser sends http request with RANGE

  - by nute

  I have a local testing environment in a Fedora virtual machine. Strangely, resources (css and js files) don't seem to work. Looking at Firebug, I see that the browser sends the HTTP request with "Range bytes=0-". The server responds with either an empty 200OK or an empty 206 Partial Content. Here is an example: Response Headers Date Mon, 23 Nov 2009 23:33:26 GMT Server Apache/2.2.13 (Fedora) Last-Modified Thu, 19 Nov 2009 22:58:55 GMT Etag "18-3aec-478c14dbee138" Accept-Ranges bytes Content-Length 15084 Content-Range bytes 0-15083/15084 Connection close Content-Type text/css Request Headers Host fedora.test User-Agent Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.5) Gecko/20091105 Fedora/3.5.5-1.fc11 Firefox/3.5.5 Accept text/css,*/*;q=0.1 Accept-Language en-us,en;q=0.5 Accept-Encoding gzip,deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive 300 Connection keep-alive Referer http://fedora.test/pictures/ Cookie __utma=26341546.1613992749.1258504422.1258569125.1258752550.4; __utmz=26341546.1258504422.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); PHPSESSID=tqf8jfmc77qihe97rl4tmhq685 Range bytes=0- If-Range "18-3aec-478c14dbee138" I don't know if the browser is sending the wrong request, or if it's the server that is doing this.

The files are being served through the "shared folders" feature of VirtualBox (could it be related?). No error logs could help me.

• What discipline does Computer Science belong to?

  - by Macneil

  Is Computer Science science, applied mathematics, engineering, art, philosophy? "Other"? To provide background, here is Steven Wartik's blog posting for Scientific American titled "I'm not a real scientist, and that's okay." The article covers some good topics for this question, but it leaves open more than it answers. If you can think of the discipline, how would computer science fit into its definition? Should the discipline for Computer Science be based on what programmers do, or what academics do? What kind of answers do you get from people who've seemed to think deeply about this?

• Can you "swap" the Sysprep answer file in Windows 7

  - by Ben

  I have a load of new Lenovo laptops which I am due to distribute in my company. We are distributed in multiple locations and I want to ship the laptops "boxed" and untouched by IT hand for distribution. We are using LANDesk to do all the software distribution and provisioning, but are currently falling at the first hurdle as when booted, the laptops kick into the Lenovo mini-setup wizard. I assume this is because they have been sysprepped at Lenovo. In order to keep with our (almost) zero touch strategy I want the users to PXE boot into a PE of some sort, which will run a script on startup which replaces the sysprep answer file with one of my own. (i.e. prepopulated with product key, company info etc.) and then reboot to complete Sysprep. The plan is that this will run, and then install the LANDesk agent as a post-sysprep task, which in turn will complete the provisioning. Anyone have any experience / know any pitfalls to look out for / can suggest a suitable, PXE-bootable PE environment? Apologies for the verbosity of the question - it takes a bit of explaining! Thanks in advance, Ben

• Learning Smalltalk as a Java programmer

  - by VeeKay

I would like to learn Smalltalk with the help of a code base available but I believe that there aren't many Smalltalk example projects available on the web. So are there any particular websites that involve learning Smalltalk (Pharo) based on some simple examples? Currently I am taking the help of Pharo By Example doc but I feel it is just not sufficient for me. I am looking for more some code examples in Smalltalk.
