How to setup Chrome as default Android mobile browser

This one is short but sweet :-)

Let’s assume that you have Android phone with Jelly Bean operating system (4.1+):

  • Find out (by opening any internet link) which application is current browser (it is usually “Internet“)
  • Go to Settings / Application Manager
  • Select All and locate current default application and open it
  • In section “Launch by default” select “Clear defaults”:

Android: clear defaults

Next time when you try to browse internet, you will get choice: select “Chrome” and press “Always“:

Android: Chrome as default browser

Android: Chrome as default browser

Import multiple VCF contacts into Gmail with Windows 7

One of rather frequent tasks is import of existing contacts from other sources into newly created Gmail account.

There are lot of tools (Gmail offer that as well) for two-way synhronization between various applications (Outlook and such), but one time, one way (Desktop -> Gmail) is not covered very well.

So, task is simple: import multiple VCF (vCard) contacts into Gmail contacts.

I will use Windows Contacts as an example inside Windows 7 (Nokia PC Suite can synhronize contacts in your phone with Windows Contacts) but procedure can be applied to any set of *.vcf files.

Get Windows Contacts into *.vcf format

  • Open Windows Contacts
  • Select “Organize / Select All
  • Select Export
  • Select “vCards (folder of .vcf files)
  • Click on Export

You will be asked to select folder where all contacts wil be exported as .vcf files:

Windows Contacts - VCF export

Let’s assume that you created new folder Cards on C:\ drive and exported *.vcf there. Also, create another subfolder of Cards folder – Final.

So, new structure is C:\Cards\Final with bunch of *.vcf files into C:\Cards

Combine all *.vcf files into one big file

Next step is to combine all *.vcf files into one big file.

Open Windows Explored and locate C:\Cards. Press and hold Shift key and right-click with mouse anywhere in folder and select option “Open command window here“:

Open command window here

Don’t get scared by black window you got; you need to type just one short command:

copy /b *.vcf Final\Big.Vcf

Merge multiple files

You can close command windows after this.

If you are English speaking person and have no strange characters in names of your contacts, you can stop here – use C:\Cards\Final\Big.vcf as source of import in Gmail Contacts and you are fine.

However, most of us non-English speaking should do final step: proper conversion of file.

Convert big vcf file into UTF8

We will use Powershell for this final step.

Press Start, type Powershell and select Windows PowerShell. Now you will be presented with blue :-) screen. Type following sequence of commands, pressing Enter on end of every line (or do copy / paste)

cd \Cards\Final
get-content "Big.Vcf" | out-file -encoding "UTF8" -filepath "ConvertedBig.Vcf"

Powershell - UTF8 conversion

That is it – import your file C:\Cards\Final\ConvertedBig.Vcf into Gmail contacts :-)

Install Oracle Client 10g on Windows 7 RTM

Install Oracle Client 10g on Windows 7 RTMOracle is rather slow when it comes to releasing Oracle Client software for new Microsoft Operating Systems. So, I did not expect that Oracle Client for Windows 7 will be ready (and it is not) in time when Windows 7 RTM is released.

However, if you are brave enough to install Windows 7 RTM :) in development environment (I am), and your work is tied to Oracle, than try this approach (worked for me):

  1. Download and unpack Oracle Database 10g Client Release 2 (
  2. Start elevated CMD prompt (CMD prompt with Administrator privileges) and navigate to folder where you unpacked files
  3. Start installation of the client with setup.exe -ignoreSysPrereqs
  4. Download from MetaLink Oracle Database 10g Release 2 Patch Set 3 and unpack.
  5. Repeat (2) – (4) for this PatchSet

For points (3) – (5) you have to have MetaLink account – I was unable to locate Patch Set anywhere else. This is drawback, and you can try using if you do not have MetaLink account.

Of course, this is just workaround until Oracle releases proper Windows 7 client.

Run Mate – great little iPhone application

Code APlus: iPhone Run Mate applicationPersonally, I am not too big fan of iPhone, especially regarding earlier versions.

Than again, as a honest technology geek, I also must admit that iPhone 3GS set high standards both in arena of mobile devices as well as in arena of PDA and general mobile platforms; operating system is way better, development support (SDK, tools) gives you opportunity to create stunning applications, and on top of that, iPhone store can give necessary head start and much needed customer and community support.

I am not talking this “from thin air” but from second hand experience, closely watching development of one great little iPhone application – Run Mate, by my friend and colleague, Aleksandar Vacić.

Beautifully crafted, both from technical and design side, small, fast and (on top of everything else) very useful – Run Mate is real example how one mobile application should look like: it should follow all the standards of the underlying ecosystem (operating system), giving to end user maximum benefit for really, really affordable price.

If you are into any kind of walk recreation – running, jogging or just walk in different paces – this is the right application for you. Head to iPhone store, and follow updates on @runmate at Twitter; for any other details / support, here is main site:

Verifying Chilean RUT code (tax number) in C#

In one of the projects at my work, I got task to verify some data (in migration process from old system to new one); one of the fields was Chilean RUT (Rol Único Tributario) or Tax Identification Number.

The RUT has 8 digits plus a validation number or letter ( and algorithm for verification (as per my knowledge) is as follows:

  1. Remove all characters except digits and last char which can be digit or letter “K”
  2. Pad with zeros (“0″) string until it is exactly 9 symbols long
  3. Multiply, from left to right, first 8 digits with following factors: 3, 2, 7, 6, 5, 4, 3, 2 and sum those results (let’s call it total)
  4. Find difference: 11 – (total % 11) (let’s call it rest)
  5. Determine control char by:
      5.1 If rest = 11, than control char “0” (zero)
      5.2 If rest = 10, than control char “K”
      5.3 Otherwise, rest is control char
  6. If the original control char (9th char) is equal to calculated control char, RUT is valid.

C# code for this could be like this:

/// <summary>
/// Routine for checking of RUT correctness
/// </summary>
/// <param name="rut">RUT to check</param>
/// <returns>true if RUT is valid</returns>
/// <remarks>Only numbers and optional "K" at the end of string are expected
/// </remarks>
public static bool IsRutOk(string rut)
    const string RutRegex = "[0-9]+K?";
    Regex RegExRut = new Regex(RutRegex, RegexOptions.Compiled | 
    int[] coefs = {3, 2, 7, 6, 5, 4, 3, 2};

    // In case that rut is padded with spaces
    rut = rut.Trim().ToUpperInvariant();

    if (!RegExRut.IsMatch(rut)) { return false; }

    if (rut.Length > 9) { return false; }

    // If shorter than 9 characters (8 + control char) ...
    while (rut.Length < 9) { rut = "0" + rut; }

    int total = 0;

    for (int index = 0; index < rut.Length - 1; index++)
         char curr = rut.Substring(index, 1).ToCharArray()[0];
         total += coefs[index]*(curr - '0');

    int rest = 11 - (total%11);

    if (rest == 11) rest = 0;

    if ((rest == 10) && rut.EndsWith("K")) { return true; }

    if (rut.Substring(rut.Length - 1, 1).ToCharArray()[0] == ('0' + rest))
        return true; 

    return false;

How to use TortoiseSVN to access Mediatemple subversion over svn+ssh

How to use TortoiseSVN to access Mediatemple subversion over svn+sshOne of important aspects when I am selecting hosting provider is subversion support. My previous host provider, DreamHost, had it, as well as my current host, Mediatemple (I am using (gs) – Grid Service option).

However, while DreamHost was allowing access to subversion repository over http protocol, Mediatemple is more strict: it requires to use svn+ssh (svn protocol over ssh). It proved that setting up this kind of access using great Windows subversion client, TortoiseSVN is a bit of a pain.

So, here is what helped me to get that done.


I will assume following data:

  • your domain hosted with media temple is
  • your admin account is
  • your domain account is 12345 (you can find out right number in MediaTemple Account Center -> Server Guide -> System Paths)
  • you followed this Mediatemple kb article and created repository named myrep

Software prerequisites are:

Generating public/private pair of keys

In order to access your subversion repository over ssh, you need to create pair of keys: private and public key which will be used for authentication of access to repository. Public key should be stored on your host account, while private key is your own and you should take great care not to give access to private key to anyone else.

Do ssh to your host (you can use PuTTY for this) and make sure that you are in your .home directory (use pwd command):$ pwd

Now, create your public/private keys executing ssh-keygen -t dsa; you will get something like:$ ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/12345/users/.home/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/12345/users/.home/.ssh/id_dsa.
Your public key has been saved in /home/12345/users/.home/.ssh/
The key fingerprint is:

You can safely press Enter on all three questions (file / passphrase / passphrase repeated)

Previous process will create two files, located here:

/home/12345/users/.home/.ssh/id_dsa – private key
/home/12345/users/.home/.ssh/ – public key

Than download (you can use FTP) file id_dsa to your computer (I will assume that you dowloaded into folder C:\Users\Dejan\Documents\Keys) and DELETE it from server:

yourdomain.comg@n10:~$ cd .ssh$ rm id_dsa

While still in shell window, rename public key to authorized_keys:

yourdomain.comg@n10:~/.ssh$ mv authorized_keys

Converting private key to PuTTY format

One final step is converting private key id_dsa to .ppk format understandable by PuTTY; navigate to PuTTY folder and fire up PuTTYGEN.Exe, and:

  1. Load id_dsa to PuTTYGEN
  2. Give comment so that you know purpose of the key
  3. Assign strong key passphrase (more on this later on)
  4. Save private key as mt-svn.ppk file

Putty Key Generator

With of without passphrase?

Step 3. above has multiple implications to the rest of the process; if you select to have passphrase to protect your private key, you will need to enter that passphrase at least when logging in computer, in order to “unlock” your private key.

If you decide not to have passphrase, you won’t need to use Pageant or any other method for managing key. However, this is basically as having heavy iron doors w/o lock. I strongly suggest to assign strong passphrase to your key.

Testing access

Now it is time to check if the keys are ok, access ok, and that everything works as expected. Use CMD prompt, navigate to PuTTY folder and execute following:

PuTTY.exe -ssh -2 -i “C:\Users\Dejan\Documents\Keys\mt-svn.ppk”

When prompted, enter ONLY your username ( ) – you should be logged on Mediatemple server WITHOUT need to enter password. If that is not true, some of the steps above were missed – check above.

Configuring TortoiseSVN

Ok, now is time to configure TortoiseSVN to access above repositroy. Right click anywhere on empty space in Windows Explorer, and select TortoiseSVN -> Settings; navigate to Network section and setup SSH client as:

"C:\Program Files\TortoiseSVN\bin\TortoisePlink.exe" -i "C:\Users\Dejan\Documents\Keys\mt-svn.ppk"

Update 2009-11-08: Also, you can try this as well:

"C:\Program Files\TortoiseSVN\bin\TortoisePlink.exe" -i "C:\Users\Dejan\Documents\Keys\mt-svn.ppk" -P 22

(adding port command, thanks to comment by Didier)

Setting TortoisePlink for svn+ssh access

(of course, this will vary depending where you installed TortoiseSVN and on location / name of your private key)

Why TortoisePlink when we were talking about PuTTY all the time? Well, TortoisePlink is just custom version of PuTTY, and it is part of TortoiseSVN and all above can be applied to it.

Browsing repository for the first time

Finally, lets test access to repository; right click anywhere on empty space in Windows Explorer, and select TortoiseSVN -> Repo-browser and enter URL:


You should be asked (twice) for your passphrase, and after short time, presented with your svn repository on Mediatemple.

Using Pageant for key store

Annoying part of ssh access is that every time you ask connection toward server (and that is basically ANY operation) you will be prompted for passphrase; that is not comfortable way of working :-)

Solution to this is another PuTTY application – Pageant – SSH authentication agent; it holds your private keys in memory, already decoded, so that you can use them often without needing to type a passphrase.

You can either start Pageant manually, and press “Add Key” to import your private key, or you can make it part of the start up group, giving list of keys to be imported:

PageAnt.exe "C:\Users\Dejan\Documents\Keys\mt-svn.ppk"

In that case, you would be asked just once when you log on for passphrase.

Now you are good to go with TortoiseSVN on Windows and Mediatemple subversion repository using svn+ssh :-)

Web.Config and Assembly Binding problems - Web.Config and Assembly Binding problemsIn a recent ASP.NET project, we had to replace NLog (excellent logging .Net library, by the way) assembly with newer one.

However, due to complexity of project, recompiling of all dependent assemblies was not an option. Suggested solution was simple – use assembly redirection:

  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <assemblyIdentity name="NLog"
        publicKeyToken="5120e14c03d0593c" culture="neutral" />
      <bindingRedirect oldVersion="" newVersion="" />

(all of this under <configuration> tag)

In a first attempt, it did not work :-( – assembly redirection did not happen. Even Fusion Viewer could not find anything strange – it looked like whole redirection part was simply ignored.

I looked (very simple) web.config again, carefully inspecting it; one line, at very top of the file, looked suspitious:

<configuration xmlns="">

After removing name space, and leaving usual:


all worked as a charm.

It turns out, that due bug in Visual Studio 2005, if you used in some point the built-in web administration tool (launched via the WebSite->ASP.NET Configuration menu item) it will add this name space to root configuration element. This will cause not just to stop Intellisense working for Web.Config but also will ignore any Assembly Binding redirection instructions.

So, if you have problem with Assembly Binding redirection in your ASP.NET application, check web.config once more :)

Trust No One … Google Included

I am a big fan of Google – I like services it offers, as well as Google “attitude” toward outside world.

Once when you start using those services, and transfer most of your digital life online, you are hooked – possibility to access/create all of data from anywhere and virtually from any device which interprets html (and that means your mobile phone) is something that you will appreciate much.

Well, maybe “was” is better tense for first sentence; and of course, being human, just one simple thing was enough to change this: they blocked my Google Account (and related GMail account):

Google Disabled My Account

For no apparent reason (one night I was sending my mail and next morning I was presented with dreadful message) I got “Sorry, your account has been disabled”. This is not just access to mail, but to Google Docs, Google Notebook, Google Reader, Google Bookmarks – just to mention ones that I use most often.

Of course, I was vaguely aware that this possibility (to get account disabled) exists, but I was also thinking that it is reserved for bad violation of Terms of Use and I was not even close to this; my usage was just regular mail usage – none of unusual activities mentioned in help / troubleshooting documents or in related posts in GMail help groups.

Also, disruptive and unannounced access restriction to the same online repository can hurt you a lot.

Add on top of that very slow response of Google Support (third day, and I have two automated responses and one form filling) and no idea when or even if I would get access to my account again – that put serious doubts in my decision to give trust to Google as big and “good” firm with my data.

Google is not nice; Google is just another company in search for steady and infinite revenue streams; all “free” services it offers are just way to expand market where ads (as main source of revenue) can be placed.

As soon as my account is enabled, I will change two things right away – change/add new online “office” provider (I am testing Zoho now) and backup all of the stuff regularly to desktop (good old offline storage) – my data and time invested to create them is of utmost importance.

Update: they enabled my account after four days; as expected, no explanation was given why account was suspended in a first place. Not nice – 4 days in speedy and busy everyday life w/o mail and many of documents and notes is at least “not nice”. Maybe all those services are free, but I would rather pay some amount for benefit of having telephone support around of clock.

Problems with Microsoft Jet OLEDB on 64bit Windows?

If you have scenario like this:

  • In your C# / VB.NET application you are using Microsoft Access database (MDF file)
  • Target machines are 64 bit machines (Vista 64 or some of the Windows Operating System flavors
  • On target machines, where you plan to deploy solution, you installed Microsoft 2007 Office System Driver: Data Connectivity Components
  • And still, you are experiencing error like this:
System.InvalidOperationException: The 'Microsoft.Jet.OLEDB.4.0' provider is 
not registered on the local machine.

Check if your application is setup for any CPU (Properties / Build / Platform target) which is default. If that is the case, change it to x86 – at the moment, there are no 64bit drivers for Microsoft Office, so only 32bit applications will work as expected.

VS 2005/2008 and Vista – IE cannot display the webpage

Vista and Visual Studio - problems with IPv6 and internal WebDev.WebServerI recently reinstalled my laptop completely (it is very nice Dell XPS M1330) and took that opportunity to make it into decent development machine (w/o all the stupid preinstalled applications).

Installed also Visual Studio 2005 and 2008, SQL 2005 Express and all the little tools necessary (ClipX for example).

Fired up latest web site on which I work on, F5 and … nothing – dreadfull message of “Internet Explorer cannot display the webpage”.

Ok, no panic here, let try Visual Studio 2008 with same web site; nothing :-( Same site, on two other development machines (Vista & Vista 64) under VS 2005 and VS 2008 works w/o problem.

Started researching and debugging; it turns out that next generation protocol IPv6, or its implementation on Vista clashes with integrated web server WebDev.WebServer.exe; WebDev has a problem finding localhost address in default configuration.

Easy fix for this is to comment ::1 entry in hosts file:

Uncomment ::1 in hosts file to correct webdev / visual studio problems

No restart is needed, either of computer or Visual Studio.

(to edit hosts file you can use notepad started with elevated rigths or “Run as administrator“; in Open dialog you type in %windir%\System32\drivers\etc\hosts)

ZYB.COM – your mobile life on web

Zyb.Com - Web service for synchronization of your mobile address book and calendarOne of my virtues (or flaws, which many would say ;-) ) is that I am (too) organized; one of the favorite principles is “do it once (and right)” – in programming, work and daily activities like entering new contact data (in phone, Outlook or web application / service) – just want to enter it once, in one place and to avoid duplication, merging, copying, version conflicting – all those things when you have one piece of data scattered all around.

Logical place for reference point is mobile phone – mobile phone is now center of daily activities: you are reachable because of it, you have your contacts, notes, calendars and mails in it. However, no matter how big screen and keyboard are (I am proud owner of Nokia E61), it is useful, for many reasons, to have all those data elsewhere:

  • Safety reasons – having a backup of your data is always a good thing
  • It is easier to transfer all those data to a new phone; replacing a phone is not very often action, but when you need to do that, it is better to be as painless as possible.
  • Easier data manipulation; using “real” keyboard and screen is much more comfortable than using phone
  • Access it from anywhere – you can access those data even when your phone is not with you

For years, I am using Plaxo service, which is rather good in free version. “Rather” because I had objections from start of using it:

  • It is slow; no matter how new versions are published, beta or not beta, web interface is slow and cumbersome. Response from service is generally “wait for it” and user friendliness is not on high level.
  • You need computer, with necessary drivers for cable/bluetooth connection with your mobile phone
  • You need to have Microsoft Outlook installed; in the era of GMAIL that is obsolete – you do not want to be tied up for one computer or to worry about licenses.

To be fair enough, most of other mobile phone synchronization solutions are far from perfect; even “native” choice for Nokia phone owners, Nokia PC Suite is generally unusable w/o Outlook installed – way and quality of work with data (over Windows Explorer shell integration) simply can not support any major data changes (even if I disregard fact that this package installs bunch of not wanted software and installs itself in system tray which bugs me additionally :) ).

I found recently ZYB – perfect “little” web service for mobile phone synchronization. Most of objections above are resolved:

  • Service is free with very simple registration procedure; number of supported phone models is very large
  • Base for synchronization is SyncML technology, supported by major phone vendors
  • Setting up phone (at least for Nokia E61) is trivial – accept and save service SMS sent by site
  • Middleman is cut out – no computer / Outlook is needed; communication phone < - > ZYB is direct, using GPRS / 3G / Wireless, whatever is available

First synchronization went fast and almost error free; “almost” because I lost tasks from my phone – tasks are treated as calendar entries; most of phones set up due date when entering tasks and ZYB was setup not to synchronize any calendar items older than 7 days; (I reported this as a bug).

So, please do full backup of your phone using “old way” before experimenting :)

Apart synchronization, ZYB offers other services – import of address book from Gmail, elimination of duplicate contacts and (unavoidable) social component – to connect with people which phones you have and they are also on ZYB (it is unobtrusive option).

Words of warning: service is still in beta and you can expect some unstabillity; also, there is trust issue – do you want to share your private data with some “foreign” site; I decided that I am fine with that, years ago, when I started using Plaxo service. It is up to you to decide for yourself.

Verdict: My recommendation.

How to Get Command Line of Launched Process

One nice improvement in Vista is enhanced Task Manager – apart from very good Resource Monitor tool, there are a lot of new attributes which you can select for running processes (View / Select Columns); especially interesting are:

  • Image Path Name
  • Command Line:

Vista - Task Manager - ‘Image Path Name’ and ‘Command Line’ attributes of an process

However, Microsoft can make some tasks much complicated that they should be; reasonable expectation is that each standard application (and Task Manager is one – it is part of Windows operating system) supports at least basics of Copy / Paste – getting data displayed in a grid in some text format.

For Task Manager that is not case :-( – there is no way (to my knowledge) to get displayed data from grid in some text form which you can use later.

Solution for this particular problem (and many other related) is in excellent SysInternals package: ProcessExplorer will display full information about selected process and allow you to copy that info on Clipboard:

SysInternals - Process Explorer - Details about process

Best of all, this nice tool is not tied for any particular Windows version – it will work in Windows 2000, XP or Vista.

IPhone close encounter – don’t like it

IPhone - Good, Bad and UglyI do not like Apple – consider them elitist company, with way too much hype about design and superiority of their products over any other similar products (implied: Microsoft ones) on the market.

However, geek in me have respect for any well crafted gadget / electronic device / software product, no matter who is manufacturer.

In the series of events (primarily caused by my friend Aleck ;-) ) I promised to my wife Maja nice present for her birthday: IPhone.

IPhone arrived couple hours ago; I tried to approach it completely open-minded.

Good – Look and Feel

This symbiotic phone / PDA is beautifully designed – simplicity and combination of materials has stunning effect on anyone who sees it / holds it. Screen is bright and clear; famous multi-touch navigation is intuitive and fast.

Default applications are good, and pleasant to use.

However, IPhone has a long, long way to go in order to be considered (in my opinion) as good business phone for daily usage:

Bad (ITunes)

Primary interface between IPhone and rest of your (mine) Windows based computer is ITunes: multi-mega (57 Mb) bloatware (with nice look of course):

  • It tries to hijack anything remotely close to multimedia on your computer
  • Synchronisation with Outlook (done with bloatware above) is seriously crippled: no Notes synchronisation and no To-Do list synchronisation
  • There is no way to directly access various elements in IPhone (Notes) if needed

Of course, you can find ways around Net to “overcome” obstacles: sending notes as mail to yourself, and reading/copy/paste on IPhone Notes, creating dummy contacts and passing notes in Note field in contacts etc. Would you do that with 50+ notes?

Data entry over screen can be a pain, especially if you have thick fingers; I believe that practice will do, but got annoyed in half hour of trying to enter some Notes.

Ugly – Missing Features

IPhone has NO To-Do lists; To-Do lists are crucial part of my daily GTD process; so, this alone would disqualify IPhone in my eyes; phone is item which is with you most of the time; being unable to enter tasks is big minus.

International support is lousy:

I was unable to enter some Serbian characters (less important) and IPhone itself is unable to recognize phone numbers in international format with country prefix; if you have number in contacts like:

+381 11 1111 1111 ( local format would be 011 1111 1111)

and if that number calls you, you will get just 011 1111 1111 on screen and no name recognised. Suggestions on Net (enter double record for each mobile: one with and one without prefix) are just suggestions :-) if you have 500+ contacts; my Nokia E61 does both things perfectly.

I understand that Apple just entered phone business and it is primarily oriented toward biggest, western speaking markets (USA) first; that time passed from launch is short; I also understand that if you want genuine well crafted and designed item and do not care too much for problems mentioned (which most of users don’t), IPhone is your best choice.

I am pretty sure that IPhone on phone market will surpass success of IPod at mp3 player market and that will be (pretty justified) most selling phone in history.

However, if you are like me, and you care about functionality as much (or even more) as for design, just wait; I believe that in year time, IPhone will be unbeatable tool for communication and business, and I am ready to wait that; for now, simply skip it – no good.

Dilbert – please come home, all is forgiven!

Dilbert - Geek next to youOne of the my icons of Programming, Internet and in general of my digital life is of course, Dilbert – brilliant creation of Scott Adams.

That is daily dose of geeky humor, sometimes strange, and sometimes it feels like Scott was peeking over your shoulder when he was drawing latest episode of Dilbert.

Unfortunately, this time, Dilbert is a bad example – or to be more precise – current implementation of Dilbert’s site is bad example of technology usage all along.

I like simple, working web solutions (pure Html + Css if possible) – so, “previous” Dilbert as a simple image and archive coming along was fulfilling all my needs; add to it reading via blog and I was more than happy.

That changed with introduction of all-shiny-flashy-flash new version of the site – that changed to a bad :-(

Those pages are now heavy, very heavy, with complex flash objects and what is worse – not working flash objects :-( You can’t easily search, you can’t easily get your daily dose of geek humor:

Problems with Dilbert Search

This was simple search, and no, parameters are not a problem – if you keep pressing Search button, you will eventually get the list of missing strips; however, getting “big” versions by clicking on found elements is another problem – does not work in most of the cases.

All in all, very bad example of heavy multimedia site – I do not mind for change, but please do basic testing of:

  • Is it working?
  • Is it working as it is supposed to (search)?
  • Can it handle load?

(I won’t get here in a rant why they changed site on this way in a first place; Dilbert’s audience is “special”, so different from average surfer or MySpace visitor; they probably know their market and someone did thorough analysis what new is needed – at least, I hope so).

Spam Free WordPress Installation

Spam Free WordPress InstallationBeing a blogger it is fun, most of the time – creating a posts, interacting with visitors via comments, making new friends and getting new skills.

However, there is a big problem: spam, especially track-back spam.

My site is basically 4 installations of brilliant blogging platform – WordPress – so, finding combinations of settings and plugins which would make maintenance of spam as easy as possible was a must. After a lot of trial/error attempts, here is combination which works perfectly:


Aksimet (included in WordPress installation, no need for separate download / install) for regular comment spam. You have to register once at WordPress.Com in order to get Aksimet API key; once done that, you are all set.


Challenge – instead of various CAPTCHA mechanism, this proved to be very efficient and less annoying for visitors.

Plugin simply asks basic mathematical questions, in order to check if is on other side of page human or robot (process).

However, warning: it is not compatible with WP-Cache – if you are using this highly effective caching system, you have to choose other options for comment approval.

Simple Trackback Validation Plugin

Finally, for TrackBack validation there is Simple Trackback Validation Plugin – simple and efficient system for fighting trackback spam, which is even worse than usual comment spam.

Time needed for installing and setting up those plugins is well spent time – instead of having 300+ daily spams, now I have 3 – 4 weekly and can dedicate to writing instead of spam fighting :-)
