The Need to "Catch" Emerging Task While Coding

Coding is a thought-consuming task and that makes the utilization of the brain very high which leaves little space for anything else including other coding task. So, if programmer has another task that come up in the middle of doing a coding task, it is most likely that he will get overwhelmed.

I think this is where the perception that programming is hard comes from, at least one from many other reason. There are just so many things that should be put in the brain's RAM. There are lots of abstraction and associations to keep in mind at the same time. However, knowing this we could make it less hard by not putting too much of it in our brain.

Let's illustrate a little. Let's say thought capacity of our brain is a 100. If a thought-consuming task takes 80 then we only have 20 left, so there's no way another 80 point task could fit in there or anything not under 20 for that matter. To make things flowing, just keep the brain from being too occupied. Keep what's in it within manageable (and fun) amount. In short, keep it sustainable.

We then need to put the surplus aside first and this is why programmer need system and discipline to do this in effective manner. I don't think we can do middle to large programming task without some kind of checklist to keep the subtask in order and cath the emerging tasks along the way. We need to only allow stuff related to current "theme" in our head and push others out of it immediately to other system before our brain start the chain reaction of spawning the emerging thought (or distraction) into someting that disrupt or flow of thinking. We could revisit this buffer afterwards, prioritize and pick the next task.

The system could be pencil and paper, text editor or, in my case, mind mapping application. It doesn't matter as long as you can depend on it as thought-catcher i.e: simple, instant entry and keep your mind clear on one single task.

There's one "sacred" principle here : There should always be task. If the task, when you work on it, proven to be insignificant or false or you find that it should be something else, do something about it first before doing something else. Cross it, rename it, whatever as long as you don't just uncounsciously forget it. One forgetting could lead your mind to wandering state and after some unproductive time you end up with "mmhh, what am I trying to do just now?". Don't let our mind do the thinking just for the fun of it. We are not maintaning our mind, give it good food and rest, just so it can have fun by itself aren't we :).

I find that being really strict to just doing one, relatively small, very concrete, well-defined thing at one time help in get more programming task done (meaing more feature added, bug fixed, etc... as oppose to more mess :) ).

Pocket Freemind, Continuing After 0.5 Release

Below are my updates on Pocket Freemind project, after the last 0.5 release. I just code away for a while, seeking to see how some ideas will be in concrete form. Now it seems apropriate to take a break and write some notes and update about it.

• The extraction of libPocketFreemind and new-more-modularized GUI. I've extraced the object model and start a new GUI on top of it to allow more flexibility to enhance more the user interface. The original GUI is still intact sharing the same libPocketFreemind (which extracted from it relatively painless) .
  
• Soft-key menu is back, complemented with custom toolbar. Standard .NET CF toolbar makes the standard soft-key unusable so I make the custom toolbar that does not interfere with it. I use picture box, panel, imagelist and a little hack. Hopefully user would still feel it as a toolbar :).
• Individual color picking instead of predefines set of style. There is now color picker for node's font and background color. Thanks to TamPPC for the code. Node style would be revisit later with editable style list.
  
• Dialogless note window. It use splitter to share screen with the map's View. It is now looks more like Freemind on the desktop. I think this way the note can be more useful and more comfortbable to enter
  
• Icon dialog updated. It now has (emulated) upper right close window button
• More align with the desktop version. The menu, term, bahavior use the desktop version for reference as long as it still makes sense. The special case of pocketpc should be considered too of course.

I guess that's it for now. Now, to close, it's time for some mandatory screenshot. Here we go :



The new note view with resizable splitter. It synched as the node is navigated. There is the node with individual color and background too.


The above is the new look of icon dialog.


And here is the new color picker. The base code is in vb. I wrapped the code relatively as it is in user control (adding an event handler), put it in a dialog, add a preview, and use it in c# project (the benefit of multilanguageness of .net :) ).

Thankfully, it came at the right time, there used to be only commercial color picker component around.

Using JEdit for AutoIt Development

I work with AutoIt today and as a JEdit user, I feel reluctant to install another Text Editor just for it. So, I searched around for JEdit-based solution. Some searching around later, got me this link. It is actually a frame from this site, I shortcut it here since it's not that obvious if you go from the main page.

It took time to follow all the instruction, even to the point I doubt whether this is all worth it :). Hopefully it will be integrated with JEdit's built-in plugin manager later for seamless installation. However, it works nicely in the end and my JEdit setup now very comfortable to work for the task.

Using Custom Action in Visual Studio 2005 Deployment Project (under Vista)

There are some quirk using Custom Action in Visual Studio 2005 and if your development machine is Vista you have even more trouble to sort. Here are what I faced recently :

• Unhelpful error message. See : "Windows Installer fails on Vista with 2869 error code.". In my case, I just run the resulting installer in an XP machine to get more informative message.
  
• When you add Custom Action for Commit phase you need to include your Custom Action Library to Install phase although you don't do anything on it e.g: override it. If you don't do this it you will have error can not save state or something. More about it here.

Thanks to google, the solutions are only one (or several) search away.

Using Directshow in .Net : DirectshowNet vs. C++/CLI

There are two usable option for using Directshow in .Net so far (excluding the abandoned-managed-directshow) :

1. Purely in .Net using DirectshowNet : code -> directshownet
   
2. Get a little bit dirty using C++/CLI : code -> c++/cli bridge-> directshow

Having tried both, I prefer using the second one for several reason :

1. You don't need to translate between what's on the directshow manual with what you need to write. On many cases you could just paste and code many boiler plate code as is and it just run. Using directshownet you have to do some mental gymnastic to do it.
   
2. Debugging would be more comfortable in native language.
   
3. You can hide the complexities of Directshow/COM exclusively in native code and have your managed code stay clean. You'll most likely end up with three layer modularisation : .net code -> c++/cli -> native c++ that access directshow. In the middle layer (c++/cli) you could provide your managed code with clean interfaces using native .net construct e.g: Properties, Event Handler.
   

However, the downside is quite obvious : you need to be comfortable with C++.

To sum up : You'll do better using C++/CLI when :

• You already familiar with C++
• Want to make application rapidly utilizing .Net

Although for those who still does not like to bother with C++/C quirks and overhead/headaches e.g: builds, linking, compilations, DirectshowNet route can provide more convinience with a "little" cost of translation and more "shady" debugging.

The better option from all these would be a .Net library that encapsulate Directshow in a more .Net-friendly way, not just a collection of "typedef"s. An even better one would be a much friendlier multimedia framework (assuming currently directshow's existing codecs and filters ported there too :) ).

Summarizing (Heavily) the Use of Event Handling Framework in .Net

I have been doing lots of code using callbacks recently and it happen to be in .Net (C#). I need some time to get used to the term, conventions and helpers that is available in .Net but in the end it is actually quite convenient with lots of predefined construct available.

Here's to sum things a little :

• For "raw" callback there's delegate. It's only a little higher than C's function pointer i.e: provide type checking.
• Above it there's event construct. It restricts delegate so the client can only add and remove itself to it but not others. Having that restriction it can now be viewed as broadcaster-subscriber model implementation (or signal-slot in qt term).
• Now, it gets more interesting : there are predefined Event Handling Framework that can be used so I can save some typing and maintenance. For typical purpose, you could use default non-generic version. What you need to do is declare the Event on the broadcaster :
  
  public event EventHandler SomethingHappen;
  
  and on the client, make the handling function based on the predefined argument pattern,
  
  private void OnPlayFinished(Object sender, EventArgs e) { ... do work... }
  
  and subscribe it somewhere :
  
  broadcasterObject.SomethingHappen += OnPlayFinished;
  
  This is what being used throughout WindowsForms-related code in VisualStudio that we could use for our own purpose too.

Doing callback-related code has already quite mind-occupying so useful help like this is very much welcome.

Get Current Position On Encoding in Directshow

When doing encoding in directshow, getting the current position (needed when you want to show progress of current encoding process) is not as obvious as for playing. I try to use the code from playing operation first i.e: get IMediaSeek interface and do GetDuration and GetCurrentPosition, but the progress is very inaccurate. The graphedit behave inaccurately also.

I found the solution later after some browsing around in Directshow help. To summarize, the solution/explanation :

IMediaSeek you got from Graph only accurate for playing operation. For file related e.g: on encoding operation, get IMediaSeek from AVIMux instead of the Graph.

The rest are the same with playing.

Children and Human's Low Level API

One of the privilege you got from having children (I have two myself) is you got the chance to see layers of human behavior API. It is exposed incrementally so you got the chance to differentiate which one is inherent to every human, what is character. If you have more than one you have even greater chance to compare things and search for invariants.

I see for myself how certain characteristic are already within a person without us do anything special to develop it. Being very attentive or very extrovert is shown in babies even when we don't condition them to be (I always thought this was very conditioned). Of course, later you can teach them and manage some of their trait to be more effective but inherently they are already have certain tendencies.

The most interesting thing for me is to see how we learn. It's really incredible to see how children learn and reflect on how we ourselves learn. You will see how those principles in AI books come from. I think you could actually subtitle any AI text-book as "how babies learn" :).

In physical level it is quite the same too. You see how those hair, teeth grow and how the faces change and shape up. Watching them learn how to walk is fun and refereshing and you see how those muscle strengthen.

It's probably a little inhuman to call it API, you could say it instead : if you'd like to learn and know more about yourself inner-workings, have a children.

Programmer Maturity and Estimation Skill

How do you measure a programmer maturity?. Recently, I am beginning to think that it is reflected on how they estimate the project and task that they need to do.

Programmer that only work on small number of code and problem tend to highly overestimate or underestimate the complexity of a project/task. So, mature programmer is not (just) someone who could code, and estimate, very good and precise in well-known problem using language that he knows well. A mature programmer would also :

• know quite clearly what he need to do/learn/research on matters that he is not used to
  
• how much/how certain/uncertain the time to take to tackle it, substask and trouble that potentially come up
  
• make clearly-thought estimation, and most importantly
  
• not emotionally attached to a problem which means not knowing or estimate something as long/hard/unknown/impossible is nothing to be embarassed/defensive about instead it's for the best if everyone being clear on what can and cannot be done
  

Less mature one would tend to be more "aggresive" and eager to prove himself by estimating too optimistically or underestimating a complexity of certain task (by fear of losing credibility or eagerness to be accepted/approved).

I think it's the same as maturity in life, you are less needing of approval/praise or trying to satisfy/impress anybody too much and more focus on doing what you can do best and keeping your integrity checked.

It does not mean we need to avoid the unknown and avoid adventure, but being mature means being clear of it and not promising something beyond our integrity to accomplish it. Say something is risky when it is and let the stakeholder decide (and share consequences later), say something certain when you have a reference/experience of it and ready to take consequence if you are proven to be wrong (you learn something new anyway).

Running .Net Winforms Application in Mono

I am curious to try running .Net Winforms application for several reason :

• Most portable GUI-based .Net app is written not using Winforms but something else e.g: gtk.
• Want to see how far the Mono team in dealing with GUI application so far (I have used server application written in .net in mono but no winform application yet).
• I have written pure and relatively simple/common winform application that supposed to run in any "good enough" winform port. Before it, my use of winforms had to goes into win32 specific "hack" which less likely to run in non-win32 .Net port.
  

So, here goes the result : it runs quite well. I only copied the binaries compiled by visual studio and the neccessary dll in windows to linux (after changing code for file/directory path to a more neutral convention) and run :

mono quicktask.exe

and the application "magically" run. Screenshot below :



It's the quicktask app from my previous post, so you could compare with the screenshot on that post. There's only some odd pixels in textbox borders but beside that, things are running fine.

Now, as long as you don't use anything strange with winform, it seems to be quite a portable development platform now. Pretty convinient if you would like to stay developing in winform or already have a codebase in it and want port it to platform that can run mono.

One note though, if you have more need like more integrated look and feel you probably want to look other alternative e.g: gtk sharp, since currently winform in mono feels like the early java gui toolkit i.e: it uses it's own rendering instead of using native widgets. It's good enough to make things run but probably won't impress too much consdering how user interfaces is getting shinier these days.

QuickTask for Snappy Task Addition on ICal-based calendar

I have been coding little application to make adding task in iCal fast and comfortable. I finally have a binary release today. Check out QuickTask here.

I find entering task using standard dialog provided by General Calendaring application quite uncomfortable. The dialog feels very "noisy" to me. I understand that most of them aim to enable user utilize ical-file standard as much as possible but for my usual use it's too bloated.

I made quicktask to make entering task to calendar more fit to my task-adding style and many others I think, especially GTD-follower who don't bother with dates, times and prioritizing task (at least when entering them).

It assume and simplify several things :

• You only assign one task exactly one category
• You only need to entery task name, description
  

It can be viewed as a facade to ical's task i.e: utilizing ical framework but only deal with stuff that match to our conceptual use of it.

I have been using for sometime now and hopefully it will be useful for others too.

Do "svn info" the TortoiseSVN Way

It's not directly obvious how you can do svn info from TortoiseSVN. I used to install separate command line svn client just to do this. However, I stumble upon this discussion :

> how could i find infos like command "svn info" ...
Right-click, choose "properties" in the explorer context menu. Then,
switch to the "SVN" tab.

Here's what I got while doing it :




I think it's pretty nice and easier compare to using separate command line client with which you need to go to console, go to that directory and type "svn info" (not to mention the hassle of installing the svn command line client). It's not that apparent for people who used to the command line command though although it seems quite consistent with how explorer arrange things i.e: Properties dialog is where the info about the selected item shown.

However, I think having some way in the main context menu of TortoiseSVN to show this info will feel straightforward and and natural for some people. info command is used just like update, commit and other typical command so they would normally expect to find it on the same place where they see those other common command.

Use AnkhSVN to Avoid Forgotten File Addition in Visual Studio

If you use Subversion with Visual Studio chances are you have been in a situation where a file you added in VS and you forgot to "svn add"ed it, thus not committed to subversion. Things will still be ok on your side, you probably only aware of this when someone else shout "Hey, who broke the build ?!".

It's where the AnkhSVN come in. I still use TortoiseSVN for my main svn client but I also use AnkhSVN to avoid the case above. When I add stuff, it automatically "svn add" it. Another important use of it for me is the instant review of what's changed from within VS and the simple way to revert changes without having to go to the windows explorer and access TortoiseSVN from there.

In short, I think it's a good complement for main svn client although not to replace it.

Setup Kubuntu 8.04 KDE 4 Remix on Toshiba Satellite 2450 Series

KDE 4 is finally released officially in Kubuntu 8.04, so it's time for me to reinstall stuff in the laptop (Toshiba Satellit 2450). Recently it's been running kubuntu 7.10 with 3d card fail to configure and I have no patience/time left to fix it. It was working in previus kubuntu, so I have a good hope that things will be better this time plus I have been itching to test KDE 4 (I had been staying away from previous betas). So, here's the recap.

The installation went really smooth. There's nothing new with ubuntu/kubuntu here, it's been known to have trouble-free installation process (although it's been known to cause a little pain afterwards :) ). Restart then login shows a welcoming KDE 4 experience, quite slick.

Now, the fun begin. The network is not working and there's no graphical setting that I can use anywhere to set the ip and stuff. It's been quite well-done in KDE 3-based system-settings, so this is quite a major drawback. A little googling "inspire" me doing things manually below :

put this on /etc/network/interfaces

auto eth0
iface eth0 inet static
address ...
gateway ...
netmask ...
network ....0
broadcast ....255

and this in /etc/resolv.conf

nameserver ...
nameserver ...

and finally execute this manually (and put in /etc/init.d/rc.local for auto-execution in booting)

route add default gw ...

Once the network works, it then quite typical fix, upgrade, install, remove, etc.. .

The next surprising thing was Firefox looked really really ugly. I remember this is the same case with the early days of kubuntu, the gtk use default look and feel (which is very bad). Easy enough, there's gtk-engine-kde4 to the rescue. Installing and setting it through SystemSetting->Appearance fixed it.

The next worth mentioning is about nvidia proprietary driver installation. I am a bit skeptical due to previous experience. But again, another round of googling, "inspire" me again (since I am not exactly doing what's in it nor the situation exactly the same).

In my case, it actually much more simpler (no need for Envy). There's a proprietary driver ready to be enabled (downloaded and configured) in the system. It's on DriverManager accessible form the StartMenu. Just need a click in enable checkbox and it automatically download and configure it. However to get it working, it still need one line in "Screen" section in /etc/X11/xorg.conf :

Option "UseDisplayDevice" "DFP"

After video card acceleration working, the rest of the time is spent playing with desktop effects, which is quite interesting and fun.

Kubuntu 8.04 with KDE 4 sure is worth it, although I really think the Network Configuration matter is a very very major flaw. It put people who isntalling it in a very difficult situation to troubleshoot. In a system where it's not a problem (preconfigured successfully in certain system?) it could be fine, but not in many cases, I think. Besides with no network configuration GUI available to play with, there's so little hint on what to do next.

Vista Firewall Block All Port Accesses Out of the Blue

I was working as usual when I suddenly cannot access the internet. Everybody else seems to have no problem with it. All my LAN access seems to not work either. I remember I got this case sometime ago and a reboot fixed it, but I have many work open on the desktop that I refuse to just give up this time.

Some diagnostic later, the result, strangely, was :

• ping works, both LAN and internet.
  
• Any access to any port anywhere fail. I can not even ssh to server in LAN that I usually able to access.

I then checked out the running tasks and there seems to be nothing out of the ordinary. The next potential trouble-maker would be Windows Firewall. The troubleshooting went :

• Check the config, seems nothing wrong
• Turn it off, It works!
• Turn it on again, it still works ?!

What was that all about?. Well, at least now I know what to do when this thing happen again.

Menu and/vs Toolbar in .Net CF Development

Developing pocketpc application using .Net CF in Visual Studio gives you lots of easiness to get the job done but also give some not-exactly-expected result sometime. You feel like it's just another app development since everything looks familiar with desktop app development only with some stuff not available, but besides that things are feels like home for desktop developer. At least until you start playing something like toolbar.

In the beginning of development, you have this style of menu :




It fits with the use of device with common left and right action button.

However, after a while you most probably think about adding a toolbar for common operation. It will be the time you find out that you no longer have access to device's left-right action button since it will then looks like below :



The toolbar need to "share" space with the menu, so the shortcut buttons no longer makes sense . It happens the same way when you have three menu like below :



But I think for the toolbar it's not really "fair", since many would expect something like below :



The above is actually achievable with a "hack" with panel and picturebox. It gets the job done, but I wonder why it's not how the standard toolbar class behave. It probably has something to do with screen space matters. However, a better option would be to let the developer choose by providing option on where the toolbar can be located and let those who want to keep left-right button functional but still want the toolbar can get what he want.

I guess, for now, .Net CF developer would need to hack away his toolbar implementation if he would like to keep the standard menu. Otherwise, if it's OK for him to have the toolbar sharing space with menu or even desire it to save space for something else, then the using standard toolbar class would be quite pleasurable.

Unit Test as a Documentation : The Case of PureMVC

I stumble upon PureMVC while searching for lightweight MVC framework for C#. The learning experience of it is not what I call pleasant one. The official documentation (which still based on ActionScript version) use very long narratives with very specific term used throughout the documentation assuming too much that the reader already familiar with it. To make matter worse, there's no executable code to try anywhere. There's no one to blame, of course, since the site already say :

Beta - Unit tests are compiled and running in target platforms, as well as a Silverlight Demo. There isn't much documentation yet, however.

However, things are changing once I take a peek at the existing unit test. This is exactly the experience that Unit-Testing proponent refer to when they say "Unit Test as an Executable Documentation". It is truly function as a documentation for me, even better than pages-after-pages narratives. It's like a "picture worth a thousand words" experience.

By relying on the unit test I can make things work in very short time. It also make the pdfs that I've read earlier starting to makes sense (despite I still think the narratives need much work to be humanely-readable). It explain how I should use certain class and how it interact with other class and most importantly, how it can produce the expected result. I don't even to compile and run them to know that it will works, it seems quite clear that it will work (in fact, I don't even bother compile the unit test, a little work of copy and pasting already show in short time that it work in my own code).

I rarely on the other side of Unit Testing world i.e: read them to makes sense of the code. I usually read my own or the co-woker (which the codebase I share and already familiarity with). Seeing their usefuleness from the purely-reader side (since it's truly "someone-else's" code) gives me deeper perspective on how they can make a difference in understanding and using the completely new code.

Call Event Handler Function Directly [.Net, WIndowsForms]

When you code Windows Forms application using Visual Studio (VS), your event handling function are generated automatically. Things are handled visually.

But let's say you have made a Menu and make it's event handler function using VS and you want make a toolbar that do the same function. Since you hate recoding everything, you'd like to call the previous event handling function on the menu directly.

It's quite easy when you understand what those parameters generated in event handling function is for. Well, assuming you don't have time to read C# book from the beginning and you need to start coding C# right after you code C++ or Java with tight deadline ahead, you just try to make sense of the code at the spot.

Generally, those function would looks like below :

private void eventHandlingFunction(object sender, EventArgs e)

It turn out that the two parameter above is

• object sender : the object from which you call this function.
• EventArgs e : stuff related to what's going on when this function is being called.

So, if you want to call them directly, just pass those two with whatever you see fit. Many times, I usually find that I just need to fill the first arg with "this" and the second one with "EventArgs.Empty", basically saying that :

• "I (the form that own this funtion) call this myself " and
  
• "There's nothing specific going on (that you need to know), I just need you to do the routine"

So, that's it, in simple situation you can just call

eventHandlingFunction(this, EventArgs.Empty);

Of course, you need to make the internal of the function can handle the situation with that kind of argument otherwise the caller need to provide a minimum necessary argument e.g: not just EventArgs.Empty, to get the function running.

Incremental Adoption of Software : From Generic App to Specialized One

Most of our software need is actually can be fulfilled by many already existing general Application. Take Text Editor and Spreadsheet for example, they are very general but highly useful piece of software. You could use them to store any kind of list or database if you can still accept the very generic feel of them and awkwardness when things get bigger. You can even utilize folder structure, file naming convention, markup convention, built-in search and replace capability to "emulate" an app.

I think we usually underestimate on how far we can go with the already-existing software and too quick to grab specialized software. But in this age of so many existing option, with many even free, who can blame us?. However, we need to also realize that adoption has it's own hidden-cost/restriction/negatives that sometime more generic application has better performance e.g: IDE vs. Emacs cases.

So, to take the best of both worlds, I guess the heuristic would be :

• Being really comfortable with available generic application. To be concrete, master application like powerful Text Editor (I use JEdit, there are others who uses Emac's fanatically) and Spreadsheet. Use their advanced feature. You will encounter that when knowing them deeply you'll find many cases that they are just suffice.
  
• Browse around and keep an eye on less widely used but powerful generic application. For example, despite it looks to have a specialized use, I find Freemind really useful in a wide variety of situation.
• If it seems enough to use the generic one in certain case, try the generic one first rather then trying to find other more specialized app, you might find out that it is actually do enough.
  
• When things get rough and you really feel that you need a more specialized app, shop around and pick the one with the most generic functionality. For example, when you only need to edit picture and Paintbrush looks plain, something like Paint.Net would be more suitable than beating yourself up trying to be graphic designer by using Gimp.
  
• When you finally use the new app, push it to it's limits and see what else you could utilize from it. Later, you could mix and match your software based on what each can do. You will have less software to deal with but still get the job done.
  

I think it will be most fulfilling using software this way and in the case of commercial software, will be more economical.

From the perspective of developer, it is useful to see what existing software that already exist that already usable enough to solve the current problem you are trying to solve with developing this new software. Developing more specialized (or more robust) software will cost the user the utilities/familiarities that he/she has on the generic app so you'd better give something much better in return.

Use Prism for Sites or Web Application that is Used/Behave as an App

Not so long ago I stumble upon Prism, a Mozilla project that aim to make using a site feels like using a desktop app. Of course, this means not all website would makes sense to be be used in Prism but for some it feels very natural.

Prism is (From the url above) :

Prism is an application that lets users split web applications out of their browser and run them directly on their desktop.

Altough technically speaking, currently it does :

• Gives you shortcut (in Start Menu, Desktop or Quicklaunch) so you can fire an url like you fire an app.
• Remove all the buttons and menu.

It might be not too impressive from this technical standpoint. But after using it for sometime I am starting to feel the difference in how I work. I put many "action"-based site to prism and now my Firefox is getting cleaner and has more focused used i.e: more research, reading, browsing. It kinda reminds of the old days :). Some monitoring and management url like Trac and XPlanner is quite helpful to be treat as prism.

Many times when I open certain site in one tab and I intend it to stick there for a while, it will then accidentally closed, which is quite annoying since I would then find myself reopening tab several times (I am quite a fan of "Close other tabs" command, so I guess this is to be expected). Now, I could just open those kinds of sites in Prism and has more freedom to do more hectic research in Firefox.

It's still really early technology, but it's already useful in my case and quite assimilated . I am looking forward for updates on this one especially highly important stuff like the use of Firefox extension (or Prism's own extension) since something like Adblock is almost de-facto standard for web accessing these days.
