  • DHCP over WiFi on CentOS 6 [closed]

    - by dongle26
    Using CentOS 6 I cannot get my WiFi interface to configure over DHCP. Here is my ifcfg-wlan0: This does not work (although it is correct): DEVICE=wlan0 BOOTPROTO=dhcp ONBOOT=yes HWADDR=xx:xx:xx:xx:xx:xx TYPE=Wireless This works: DEVICE=wlan0 BOOTPROTO=none ONBOOT=yes IPADDR=192.168.0.253 NETMASK=255.255.255.0 DNS1=192.168.0.99 GATEWAY=192.168.0.99 HWADDR=xx:xx:xx:xx:xx:xx TYPE=Wireless I don't want a static IP address, I want a DHCP assigned address. Update: Both of the above configs are correct. Please don't downvote, this really didn't work for me. It must be a bug in CentOS or my wireless driver. See my answer for details.

  • Complexity of a web application

    - by Dominik G
    I am currently writing my Master's Thesis on maintainability of a web application. I found some methods like the "Maintainability Index" by Coleman et.al. or the "Software Maintainability Index" by Muthanna et.al. For both of them one needs to calculate the cyclomatic complexity. So my question is: Is it possible to measure the cyclomatic complexity of a web application? In my opinion there are three parts to a web application: Server code (PHP, C#, Python, Perl, etc.) Client code (JavaScript) HTML (links and forms as operators, GET-parameters and form fields as operands!?) What do you think? Is there another point of view on the complexity of web application? Did I miss something?

  • Running Webapp on Mac in UTC (either changing MacBook timezone or tomcat timezone)

    - by Andy A
    To run my web app, I need to set my timezone to UTC on my MacBook. I can do this temporarily by opening a Konsole and entering sudo ln -sf /usr/share/zoneinfo/UTC /etc/localtime However, my timezone returns to normal when I restart my machine! Any advice? Edit : The response to this question by 'Celada' implies that I can just make my Server UTC. I am using Apache Tomcat 7. Adding to Celada's response, how can I make it UTC? Update - 3rd April : Following Celada's response, I have tried adding SetEnv TZ UTC at the top of startup.sh. This didn't seem to make a difference. After some research, I tried adding export JAVA_OPTS="-Duser.timezone=UTC" to startup.sh, but this too had no effect. Am I adding the correct command to the correct file?

  • WSS and CAG , _layout pages break

    - by Mike
    Alright, I've searched everywhere and I cannot find the answer, due to the rarity of our setup. WSS 3.0/IIS 6.0/WinServer 2003 We have a sharepoint site that is in good shape, almost. Its TCP and SSL port are uncommon and need to be rerouted to work properly. This is where the Citrix Access Gateway (CAG) comes in play. It will redirect any request from URL (something.something.com) to the correct SSL port on the correct server. My AAM is configured to Default something.something.com and nothing else, since the CAG will provide the port. We use FBA, and require SSL. This works perfectly for everything that is safe or that is anything that an end user can see, but if I try to add a webpart, it errors out. Whereas if I add it internally, or bypass the CAG the webpart adds fine. The same goes for most of the _layouts pages, like _layouts/new.aspx. If I add a Link List/Doc library on the something.something.com, it errors out (Page cannot be displayed) and the page won't display, but if I try it with an internal address it will work fine. I found that if I am trying to add something or doing anything administrative, the site will navigate to the pages that I need to go to fine, but when i actually ADD something the URL will change from something.something.com to something.something.com:SSLport, thus erroring out the site. The URL with the SSL port shows on the Site URL when navigating to Site Settings. However, if I bypass the CAG, using the internal address the _layouts page works like a charm and i can add anything. All the CAG does is reroute a DNS request to the provided server and port. I've tried reextending the application, no luck same thing. I've tried changing the AAM to hide the port and the CAG rejects it. I've tried to recreate a new webapp/site collection with the same rules on the CAG, same thing occurs. Correct me if I'm wrong, and please provide me with some feedback and answers. Any suggestions would be very appreciated. Is it the CAG or the Alternate Access Mappings (AAM)?

  • Price comparison sites and its effect on Google ranking

    - by Jivago
    I am the webmaster of a website that contains roughly 10,000 products. I would be possibly interested to index those products in a price comparison site like PriceGrabber, Nextag, Shopbot, etc. The principle of price comparison sites is great for an actual user that want to compare prices but my main concern is the effect it could have on my actual ranking on Google... Since a site like Shopbot uses a CPC model (Cost-per-click), all the links on the website are builted to track clicks (IE: http://www.shopbot.ca/r.html?i=3&catc=2&refshop=5706&refshopcodeid=42587349), it uses redirection, no direct links (So no direct backlinking). In your opinion and/or experience, is this a smart, business wise, seo wise move or not? THANKS!

  • Facebook verify account

    - by dman
    I can't login to Facebook because they think someone tried to hack my account. To verify it's really me they present me with photos that my friends have been tagged in and ask me to give them the correct names of who is tagged in the photos. Now because alot of my friends think it's funny to tag themselves in random photos of others, or tag themselves as objects in photos, I can't successfully get all 10 correct. I also have alot of friends of friends that have added me that I don't know closely enough to identify the back of their head in a distant blurry photo. Facebook only allows one attempt per hour to try this. How am I supposed to restore my account when they have such a stupid method to prove identity?

  • How to Automate .inf PnP Windows 7 Drivers with Wildcard?

    - by Dos_Probie
    I am trying to automate the PnP driver installs for Windows 7 with either of the below batch files via For loop and wildcard for the .inf file. The rundll32 batch reads and echos the correct .inf file but then gives me the "Error Installation failed" and with the pnputil batch it runs without any error put does not install. How can I correct the batch files to install the inf correctly? @echo off&color a&setlocal enabledelayedexpansion cd %~dp0 set PnP=rundll32 syssetup,SetupInfObjectInstallAction DefaultInstall 128 .\*.inf for /f "delims=" %%a in ('dir/b %PnP%') do ( echo == Installing PnP Drivers == "%%a" ::or set PnP=pnputil -i -a "*.inf" for /f "delims=" %%a in ('dir/b %PnP%') do ( echo == Installing PnP Drivers == "%%a" ping -n 3 localhost 1>nul start "" /wait %PnP%\%%a ) cls echo. * DONE * pause exit

  • Interpolate air drag for my game?

    - by Valentin Krummenacher
    So I have a little game which works with small steps, however those steps vary in time, so for example I sometimes have 10 Steps/second and then I have 20 Steps/second. This changes automatically depending on how many steps the user's computer can take. To avoid inaccurate positioning of the game's player object I use y=v0*dt+g*dt^2/2 to determine my objects y-position, where dt is the time since the last step, v0 is the velocity of my object in the beginning of my step and g is the gravity. To calculate the velocity in the end of a step I use v=v0+g*dt what also gives me correct results, independent of whether I use 2 steps with a dt of for example 20ms or one step with a dt of 40ms. Now I would like to introduce air drag. For simplicity's sake I use a=k*v^2 where a is the air drag's acceleration (I am aware that it would usually result in a force, but since I assume 1kg for my object's mass the force is the same as the resulting acceleration), k is a constant (in this case I'm using 0.001) and v is the speed. Now in an infinitely small time interval a is k multiplied by the velocity in this small time interval powered by 2. The problem is that v in the next time interval would depend on the drag of the last which again depends on the v of the last interval and so on... In other words: If I use a=k*v^2 I get different results for my position/velocity when I use 2 steps of 20ms than when I use one step of 40ms. I used to have this problem for my position too, but adding +g*dt^2/2 to the formula for my position fixed the problem since it takes into account that the position depends on the velocity which changes slightly in every infinitely small time interval. Does something like that exist for air drag too? And no, I dont mean anything like Adding air drag to a golf ball trajectory equation or similar, for that kind of method only gives correct results when all my steps are the same. (I hope you can understand my intermediate english, it's not my main language so I would like to say sorry for all the silly mistakes I might have made in my question)

  • ubuntu-10.04-desktop-i386 does not work with HTTP preseed?

    - by netvope
    Installation media: ubuntu-10.04-desktop-i386.iso I tried a lot of different boot parameters, but either the installer ignored the preseed configuration, or it boot itself directly as LiveCD. An example of the boot parameters I've tried: auto url=http://mydomain.com/path/preseed.cfg boot=casper only-ubiquity initrd=/casper/initrd.lz quiet splash -- If I remove only-ubiquity, it boots as a LiveCD. If I remove boot=casper, it won't boot. If I add vga=normal locale=en_US console-setup/layoutcode=us console-setup/ask_detect=false interface=auto, it still can't do automatic install. If I remove auto, it's the same. What is the correct boot parameters for launching such an installation? From the apache log of the server hosting preseed.cfg, I see that the installer has no problems fetching the preseed file. My preseed file is almost identical to the one at https://help.ubuntu.com/10.04/installation-guide/example-preseed.txt. Moreover, I have run debconf-set-selections -c preseed.cfg to ensure that the preseed file is correct.

  • How should I work out VAT (UK tax) in my eCommerce site?

    - by Leonard Challis
    We have an ecommerce system in place. The sales actually go through Sage, so we have an export script from our system that uses a third-party Sage Importer program. With a new version of this importer, values are checked more thoroughly. We are getting 1 pence discrepancies because of the way rounding works - our system has always held prices and worked to 4 decimal places. In the checkout the totals would be worked out first, then the rounding to 2 decimal places. The importer does rounding first, though. So, for instance: Our way: Product 1: £13.4561 Qty: 2 Total inc VAT = £32.29 (to 2dp) Importer way: Our way: Product 1: £13.4561 Qty: 2 Total inc VAT = £32.30 (to 2dp) Management are reluctant to lose the 4dp but the developers of the Sage importer have said that this is correct and makes sense -- you woudn't sell a product for £13.4561 in a shop, nor would you charge someone tax at 4 decimal places. I contacted the HMRC and the operator didn't really give me much to go on, telling me a technician would phone back, to which they haven't and I'm still waiting after almost a week and numerous follow-up calls. I did find a PDF on the HMRC's web site, but this did about us much to confuse me as it did to answer my questions. I see that they're happy for people to round up or down, as long it is consistent, but I can't tell whether it should be done on a line by line basis or on the end total of the order. We are now in the position where we need to decide whether it's worth us doing one of the following, or something completely different. Please advise with any experience or information I can read. Change all products on the site to use 2dp Keep 4dp but round each line in the order to 2dp before working out tax Keep it as it is and "fudge" the values at the export script (i.e. make that values correct by adding or subtracting 1p and changing the shipping cost to make the totals still work out) Any thoughts?

  • Differences between software testing processes and techniques?

    - by Aptos
    I get confused between these terms. For examples, should Unit testing be listed as a software testing process or technique? I think unit testing is a software testing technique. And how about Test driven development? Can you give me some examples for software testing processes and techniques? In my opinion, software testing process is a part of the software development life cycle. For example, if we use V-Model, the software testing process will be System test, Acceptance test, Integration Test... Thank you.

  • Subscribable World Cup 2010 Calendar

    - by jamiet
    I bang on quite a lot on this blog about ways in which data can get published over the web and one of the most interesting ways, in my opinion, of publishing data in a structured manner that is well understood is to use the iCalendar specification. There isn’t much information in the world that doesn’t have some concept of “when” so iCalendar is a great way of distributing that information. You have probably used iCalendar at some point without even knowing about it. All files with a .ics suffix are iCalendar format files and that is why you can happily import them into Outlook, Hotmail Calendar, Google Calendar etc… where they can be parsed and have the semantic data (when, where and who) extracted from them. Importing of iCalendar format data is really only half the trick though; in my opinion the real value of iCalendar-formatted calendar is the ability to subscribe to them. Subscribing has a simple benefit over importing but that single benefit is of massive importance: a subscriber to an iCalendar calendar can periodically check to see if any updates have been made and, if they have, automatically update the local copy. The real benefit to the user is the productivity gain – a single update to an iCalendar means that all subscribers are automatically made aware of the change and there is zero effort on the part of the subscriber; as my former colleague Howard van Rooijen is fond of saying, “work smarter not harder” – nowhere is this edict more ably demonstrated than subscribing versus importing of calendars. If you want to read some more thoughts about iCalendar then go and read my past blog post Calendar syndication - My big hope for 2009's breakthrough technology or better still go and seek out Jon Udell who speaks very authoritatively on the issue of iCalendar. With this subject of iCalendar on my mind I was interested to discover (via Steve Clayton’s blog post Download the world cup fixtures) that the BBC had made a .ics file available containing all of the matches in the upcoming World Cup. As you can probably guess this was a file that was made available so that it could be imported into your calendar of choice. It had one obvious downside though, right now nobody knows who is going to be playing in the knock-out stages so the calendar looks like this: with no teams being named after 25th June. How much more useful would this calendar have been if the BBC had made it possible to subscribe to the calendar instead, thus the calendar could be updated with the teams for the knock out stages when they are known and every subscriber would have a permanently up-to-date record of all the fixtures in their calendar. Better still, the calendar could be updated with match results as well or perhaps even post a match report from the BBC sport pages; when calendars are made subscribable a sea of opportunity opens up for distribution of information. So with that in mind I have decided to go one better than the BBC. I have imported their .ics into a brand new Hotmail calendar and made it publicly available at the following URLs: HTML http://cid-dc1ed121af0476be.calendar.live.com/calendar/World+Cup+2010/index.html iCalendar webcal://cid-dc1ed121af0476be.calendar.live.com/calendar/World+Cup+2010/calendar.ics The link you’re really interested in is the second one - click on that and it should open up in your calendar software of choice. Or, if you want to view it in an online calendar such as Hotmail Calendar or Google Calendar, copy and paste that URL into the appropriate place. Some people have told me they’re having trouble with the iCalendar link in which case hit the HTML link and then click “View ICS” at the resultant web page: I shall endeavour to keep the calendar updated throughout the World Cup and even if I don’t you’re no worse off than if you had imported the BBC’s .ics file so why not give it a try? If I do keep it up to date then you will have a permanent record of the 2010 World Cup available in your calendar. Forever. If you have your calendar synced to your smartphone then you’ll be carrying match reports around with you without you having to do a single thing. Surely that’s worth a quick click isn’t it?   If you have any thoughts let me have them in the comments below. Thanks for reading. @Jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • X technology is dead

    - by Daniel Moth
    Every so often, technology pundits (i.e. people not involved in the game, but who like commenting about it) throw out big controversial statements (typically to increase their readership), with a common one being that "Technology/platform X is dead". My former colleague (who I guess is now my distant colleague) uses the same trick with his blog post: "iPhone 4 is dead". But, his motivation is to set the record straight (and I believe him) by sharing his opinion on recent commentary around Silverlight, WPF etc. I enjoyed his post and the comments, so I hope you do too :-) Comments about this post welcome at the original blog.

  • nginx + varnish + apache differente IPs in VirtualHost Apache

    - by zeusgod
    Hi, My idea is put NGINX as proxy to redirect to Varnish (cache static content) and then proxy to apache with a lot of VirtualHost in different IPs. My problems is that I would know how can configure Varnish to send access to correct IP, I am going explain: NGINX: Listen in: 10.10.10.10, 20.20.20.20 and 30.30.30.30 on ports: 80 and 443 Proxy redirect to Varnish 10.10.10.10:8080, 20.20.20.20:8080 and 30.30.30.30:8080 Varnish: Port: 8080 - THIS IS THE PROBLEM Proxy content not static to Apache on port 8000 - THIS IS THE OTHER PROBLEM Apache2: Listen in: 10.10.10.10:8000, 20.20.20.20:8000 and 30.30.30.30:8000 Response correct VirtualHost This is the idea. When I try with one IP only, all work correctly, because Varnish is only listen in one IP and port and send to backend in one IP and port too. Could you help me to configure Varnish or there is a best way to configure similar scenario please?

  • Java - learning / migrating fast

    - by Yippie-Kai-Yay
    This is not one of those questions like "How do I learn Java extremely fast, I know nothing about programming, but I heard Java is cool, yo". I have an interview for a Java Software Developer in a couple of weeks and the thing is that I think that I know C++ really good and I am somewhat good at C# (like, here I can probably answer on a lot of questions related to these languages), but I have almost zero experience with Java. I have a lot of projects written in both languages, I participiated in several open-source projects (mostly C++, though). Now, what should I do (in your opinion) to prepare myself for this Java interview. I guess migrating from C# to Java should be kind of fast, especially when you know a lot about programming in global, patterns, modern techniques and have a lot of practical experience behind you. But still two weeks is obviously not enough to get Java in-depth - so what should I focus on to have the best chances to pass the interview? Thank you.

  • Level Design V.S. Modeler

    - by Ecurbed
    From what I understand being a level designer and a character/environment/object/etc Modeler are two different jobs, yet sometimes it feels like a Modeler can also do the job of the level designer. I know this also depends on the scale of the game. For small games maybe they are one and the same, but for bigger games they become two different jobs. I understand a background in some modeling could not hurt when it comes to level design, but the question I have is: Do jobs prefer people who can model for level designing? This way they can kill two birds with one stone and have someone to create the assets and design the level. What is your opinion of the training? Does level design contain skill sets that make them completely different from what a modeler can do, or is this an easy transition for a modeler to become a level designer? Can you be a bad level designer but a good modeler and vice versa?

  • Ubuntu 13.10 Installing MariaDB

    - by Ecaz
    I have tried everything to install MariaDB on this clean Ubuntu installation but I keep getting this error, Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: mariadb-server : Depends: mariadb-server-5.5 (= 5.5.33a+maria-1~saucy) but it is not going to be installed E: Unable to correct problems, you have held broken packages. I have followed this guide to try and install it, http://www.unixmen.com/install-lemp-server-nginx-mysql-mariadb-php-ubuntu-13-10-server/ And I have also followed the "official" guide on the MariaDB downloads page for 13.10 https://downloads.mariadb.org/mariadb/repositories/ But nothing seems to be working.

  • Linking Libraries in iOS?

    - by Joey Green
    This is probably a totally noob question but I have missing links in my mind when thinking about linking libraries in iOS. I usually just add a new library that's been cross compiled and set the build and linker paths without really know what I'm doing. I'm hoping someone can help me fill in some gaps. Let's take the OpenCV library for instance. I have this totally working btw because of a really well written tutorial( http://niw.at/articles/2009/03/14/using-opencv-on-iphone/en ), but I'm just wanting to know what is exactly going on. What I'm thinking is happening is that when I build OpenCV for iOS is that your creating object code that gets placed in the .a files. This object code is just the implementation files( .m ) compiled. One reason you would want to do this is to make it hard to see the source code and so that you don't have to compile that source code every time. The .h files won't be put in the library ( .a ). You include the .h in your source files and these header files communicate with the object code library ( .a ) in some way. You also have to include the header files for your library in the Build Path and the Library itself in the Linker Path. So, is the way I view linking libraries correct? If , not can someone correct me on this ?

  • Windows Phone 8 development on Windows 7 - is it or will be possible?

    - by Tiby
    I was trying to install Windows Phone 8 SDK on my Windows 7 machine and it hit me with the 'supported only on Windows 8' message. I actually wanted to develop Phone 7.5 apps on Visual Studio 2012, impossible thing with the 7.1 SDK, so I thought 8 SDK will do the job. As if it was not enough that the 8 SDK was controversial upon release, now that it's generally available, to me it seems like a horrible decision to make it available only for Windows 8, because in my humble opinion, no serious and sane developer will install Windows 8 ever, or at least in the near future, just because of the Metro UI. So, anyone knows any workarounds for developing Windows Phone 8 on Windows 7, or at least develop for 7.5 but using Visual Studio 2012?

  • Why is there a "new" keyword in Go?

    - by dystroy
    I'm still puzzled as why we have new in Go. &Thing{} is as clear and concise as new(Thing) to Go coders and it uses only constructs you often use elsewhere. It's also more extensible as you might change it to &Thing{3} or &Thing{Feets:7}. In my opinion, having a supplementary keyword is costly, it makes the language more complex and adds to what you must know. And it might mask to newcomers what's behind instantiating a struct. It also makes one more reserved word. So what's the reasoning behind new ? Is it something useful ? Should we use it ?

  • Is it Hard to Write a Blog?

    - by Joe Mayo
    Responding to a tweet I received, asking if I found it hard to write a blog and keep it interesting. This is one of the situations where a 140 character response doesn’t do a question justice. There’s a lot to think about between the subjects of writing, subject matter, and entertainment.  Here’s my take on each of these three topics: There’s all types of writing you can do with various degrees of difficulty. If you’re writing a book and you have a gazillion editors bleeding over your every utterance, then the task becomes harder because you’re second-guessing yourself, not knowing whose opinion will be violated. However, if you’re communicating in a public forum, not too many people care about the grammar as much as whether what you have to say is correct.  For a blog, I would say it’s somewhere in-between.  Right now, I’m using Windows Live Writer, which gives me a few advantages to just typing into the blog editor, such as spelling correction and the ability to save my work and resume later.  Overall, writing is one of those things that you just need to get used to.  It’s an essential skill for developers because you need to document your work, depending on what your definition of proper documentation is, and communicate with other developers via various communications mediums. Not begin good (or not thinking that you’re good) shouldn’t hold you back.  Like most things in life, practice will improve your skill.  So, push away that inner voice that keeps you from moving forward and just do it. A good grasp on the subject matter you’re writing about helps.  However, don’t let a lack of knowledge stop you from writing about something. I recall reading something a while back by a developer who didn’t know a technology but wrote about their experience in learning it. They ended up learning more by expressing their thoughts in writing. If you look around out many blogs today, there are many items written by developers learning what they’re writing about.  So, whether you are sure or unsure, you can still write – just be honest with yourself and your readers about what you’re writing. Also, don’t be afraid to have a different opinion or worry if someone will disagree.  I’ll freely admit that it took a while for me to become accustomed to being criticized. Take the good with the bad and use the bad to make yourself better. Guaranteed, someone will disagree with one or more parts of what I’ve written here or think they have a better approach. No problem, more power to them, and whatever constructive comments they have will be a benefit to me in the future; Otherwise, to h*ll with them. :)  Every time you get knocked down, get right back up, dust the dirt off your backside, and keep moving forward.  You’ll learn in time how to align a subject with your own presentation of the material. Entertainment could be hard or could be natural, depending on the personality of yourself and your target audience. It’s even more challenging because you can say something you think is funny and someone will be offended. In fact, there are a lot of things that you shouldn’t say in the name of a joke, but I won’t mention any of them here for want of not offending anyone. Of course, I probably offended someone by saying that and there is probably an organization somewhere in the world out to get me now. I’m probably not the best person to be giving you advice on entertaining an audience.  I mean, every time I try to tell a joke on Twitter 10 people unfriend me. Okay, maybe 15, but you get my point. One thing you might be interested in knowing is that it’s not too hard for one technical person to entertain other technical people, especially when the subject is of interest.  It’s the excitement in each sentence and passion in each paragraph that will keep another developer entertained and interested in what you have to say. Not everyone will like what you’ve written, but the important part is to find your own voice and it’s likely that there is one person in some corner of the world that likes what you have to say, even if it’s your mom and she doesn’t understand a single word you write. :)   If I could leave you with one final thought; Just do it and don’t let anyone or anything hold you back.   Joe

  • sql and web encoding problem

    - by Marki
    Guys, I've got an encoding problem I believe. I have upgraded from phpBB2 to phpBB3. The old databases were in latin1, the new ones have utf8 encoding. Already during the upgrade process some rows of the DB were only read partly into the new version, because of strange characters as it turned out. When I use PHP's mb_convert_encoding() function to convert those strings to UTF8 they end up e.g. as 0x0093, i.e. they must have been some kind of double quotes. Even after doing this conversion, they still show up as 0x0093 in the browser (the squares with 0093 in them when the browser does not know what to display). Can someone explain the problem here? I'm a little confused and afraid I don't see all the dependencies that need to work to have the correct encodings and the correct display thereof...

  • When you are expecting a promoting, do you prefer an technical or administrative job? [closed]

    - by Darf Zon
    As a programmer, they offered me an upgrade as project manager, but my feeling is that I can have a more effective contribution in a technical role that in one administrative. When should I accept the promotion? Generally speaking, I think that people should do what they love and what they like to do, from the time you are offered a promotion to someone is because he has been doing a great job today, and certainly learn new things in the new position and obviously have a better financial remuneration, but if it really is something you do not like do not good that post. That's my opinion.

  • Entity Type specific updates in entity component system

    - by Nathan
    I am currently familiarizing myself with the entity component paradigm. For an example, take a collision system, that detects if entities collide and if they do let them explode. So the collision system has to test collision based on the position component and then set the state of those entities to exploding. But what if the "effect" (setting the state to exploding) is different for different entities? For example, a ship fades out while for an asteroid a particle system must be created. Since entities and components are only data, this must happen in some system. The collision system could do it, but then it must switch over the entity type, which in my opinion is a cumbersome and difficult to extend solution. So how do I trigger "entity type dependend" updates on an entity?
