How to copy files easily from PC to Samsung Galaxy

2012-01-19T10:40:00.000-08:00

I tested it with Galaxy Ace which is not recognized as a regular USB device when plugged in. I installed Kies which is recommended by Samsung and saw that it was an ugly piece of software. Luckily I discovered that when Kies is running then the phone is accessible from my regular file manager as a storage device, so you can simply copy files on the phone with your favorite file manager without using Kies.

Kindle can't be used if connected via USB even if ejected - Windows 7

2011-10-08T10:01:00.000-07:00

On Windows 7 I plugged in the Kindle into the USB slot and it said I had to eject it if I want to use it during charging. I did it by choosing "safely remove device" from the menu of the usual USB icon in the bottom right corner, but the Kindle kept saying I have to eject it.

Turns out there is an Eject option if you click on Computer in the Start Menu and then right click on the attached Kindle device. When that Eject is selected then the Kindle can be used during charging.

How to do a partial search in your GMail account

2011-09-02T00:11:00.000-07:00

GMail's search feature is not that great, because it cannot find mails if only the beginning of a word matches the search query. So if you search for travel then it won't find mails with the word travels.

This is very annoying and makes searching much less useful than it could be.

Luckily, there is a solution. You should index your mail with a different tool which can do these kinds of searches. One such tool is the Opera Browser which has a very capable mail client in it. Don't worry, you don't have to use Opera for browsing if you don't want to (though, it's a great browser). You can use it for GMail search only.

Here you can read about setting up Opera's mail client for GMail and make sure you set up it so that Opera only copies the mails from GMail, but leaves the originals there (probably this is the default). When you are done Opera will start copying the mails which may take some time if you have lots of emails.

When it is done then you can start searching your messages with the Opera Mail client and it will find words even if the search matches only the beginning of the word not the whole word.

Just open the Mail panel and click on the Unread view, for example, and in the top right corner there is the search box.

Backup your files to the net automatically and securely with Dropbox and RAR

2011-08-25T12:49:00.000-07:00

So you want an automatic backup which you set up once and then you can forget? If so then first install Dropbox. Dropbox works in a very simple way, it creates a directory (usually "My Dropbox") and everything you copy there is uploaded to Dropbox's servers automatically.

The next step is collecting the files you want to backup. RAR is a good tool for that. It can put all your files into a single archive file and it can take the directories to be archived from a file list.

So create a file in which list in separate lines the directories you want to backup and then create a batch file with a command like this:

"C:\Program Files\WinRAR\Rar.exe" u "c:\My Dropbox\backup.rar" @c:\backup_file.list

This command reads the list of files to be backed up from c:\backup_file.list and puts the result in the Dropbox directory. The command u means the archive will be updated, so only files you change is written to the archive if you run the command again and again.

Because that is what you should do and you should do it automatically, so run the batch file daily with the Task Scheduler.

Are we ready? Almost. If you want to secure your stuff (and why wouldn't you?) then you should encrypt your backup file. RAR can handle this too easily, just add two more switches to the command line in the batch file and replace password with your own encryption password:

"C:\Program Files\WinRAR\Rar.exe" -p"password" -hp u "c:\My Dropbox\backup.rar" @c:\backup_file.list

That's it. It backs up your files, encrypts them and uploads the backup to the cloud with Dropbox. And with the help of the Task Scheduler all that happens automatically. Isn't it a great thing?

Watching country blocked Youtube videos

2011-06-22T03:01:00.000-07:00

Is a Youtube video blocked for your country? It sucks, doesn't it? But it's easy to circumvent the block. Just go to this site which provides a proxy video player which usually can play blocked videos just fine. Just copy the video URL and paste it.

Why there is no Android in Eclipse Galileo Preferences

2011-04-01T06:01:00.000-07:00

You have to run Eclipse in administrator mode when installing the Android SDK, otherwise it won't work.

Microsoft Wireless Mouse stops working

2011-03-23T08:57:00.000-07:00

It's always interference for me. Today it stopped working after several weeks of problem free behavior. Try putting the receiver somewhere else. It solved the problem for me.

Split a long audio mp3 file into smaller parts

2011-03-04T10:29:00.000-08:00

I had a several hours long audiobook file and it was cumbersome to handle it with my mp3 player, because it had only rudimentary controls for moving in the file. So I wanted to split it into smaller parts and as it turned out it's quite easy. The file can simply cut into pieces, no complicated trickery is needed. I used Total Commander to split the file and it worked beautifully. Try it yourself.

How to block sneaky pop up windows?

2010-08-08T03:50:00.000-07:00

Probably you've already encountered popup windows from LiveJasmin, 888.com and similar sites. Sometimes they can be blocked with a popup blocker, but other times they find a way to open their windows somehow. In these cases instead of blocking them you can close them automatically.

Here's how to do it:

For Firefox visit the GreaseMonkey manual and look up how to install GreaseMonkey and user scripts. These are pretty easy to do and when you are done, install this script:

if (window.location.hostname.match("livejasmin.com") ||
window.location.hostname.match("888.com"))
window.close();

This script checks every time a new page is opened if it's one of the unwanted pages (you can add more, of course), and if so, it closes it instantly.

Google Chrome has a built-in support for scripts, so you can use that. Opera ditto. Explorer too.

Have fun.

Here's how to type an orange LOL on Youtube

2010-05-17T21:36:00.001-07:00

Just type #LOL. You can also try #FAIL #FTW #WHAT #OMG.

The reason why Windows deletes directories so slowly

2010-05-16T03:42:00.000-07:00

Because you delete into the trashcan. Try Shift-Delete in the file manager instead of Delete and you'll delete things much faster. But beware: you won't be able to restore things deleted this way!

How to overcome the 200 video limit of a Youtube playlist

2010-05-02T09:26:00.000-07:00

The Youtube playlist randomizer mentioned before acquired a new feature. It can mix and play videos from several playlists instead of only one.

You can use it to listen your classical and pop music playlist mixed together if you want, but it is much more useful to overcome the built in Youtube playlist limit.

A Youtube playlist can only have a maximum of 200 videos in it. If you have more than 200 favorite videos then you can put them into separate playlists and using this feature you can play those lists like a single, long playlist, so you can effectively have a playlist of infinite length. In theory, at least :).

How to fix show me as away when inactive in Skype?

2010-04-10T12:58:00.000-07:00

Setting your Skype-status to away automatically when you are away from the computer is not really working anymore, is it? If that's the case it's easy to fix.

Go to Tools/Options and change Show me as away after X minutes to some other value. Like 4 minutes. Save it.

Then go to Tools/Options again and set it to some other value again like 5 minutes. Save it.

After you changed it twice it will work correctly. Stupid, isn't it? But at least it can be fixed.

How to play a Youtube playlist in random order (shuffle)?

2010-04-04T23:35:00.000-07:00

With the recent redesign of Youtube they've taken out the randomize option, so you can set your playlist to autoplay, but it will always play in the same order. Boring, isn't it?

Luckily, there is a handy site which allows you to play/shuffle a Youtube playlist in randomized order. It does not have a fancy design, but it does the shuffling well.

You just give your Youtube user name, it lists your playlists and you can choose one to play in random order. It even have a Play Next button if you want to skip a number.

How to fix atapi.sys Packed.Protector.C trojan warning by Avg?

2009-12-07T04:04:00.000-08:00

I got some virus called av_dm.exe. Check your startup programs with msconfig to find where it is located, delete it from everywhere and untick these entries from msconfig startup.

It fixed the process which ate the CPU, but AVG still complained about a trojan in atapi.sys

I didn't know what to do with it, because AVG couldn't remove it, so I downloaded the service pack for XP manually (search for it on Google), and renamed it to .cab, so I can look into it. Renamed the trojan atapi.sys to .bak in case the fix doesn't work, copied atapi.sys from the service pack and rebooted.

This eliminated the warnings by AVG. Let me know if it works for you or if you have a better idea how to deal with this pest.

Opera not responding message is annoying

2009-09-04T07:32:00.000-07:00

Installed Opera 10 and hoped the dreaded "not responding" message went away, but it happened again today. Unexpectedly Opera stops doing anything and if I click with the mouse the title says "not responding".

I don't know how long it stays this way, because after like 20 seconds I lose my patience and restart it to make it work again.

Anyone else experiences this bug? What is the cause of it?

exiap6415386.exe creeped into my windows startup

2009-09-03T08:15:00.000-07:00

During browsing the computer suddenly rebooted itself. This was suspicious, I instantly thought some badware installed itself and rebooted, so it can hook into the boot process. When Windows restarted something started to eat the CPU. Windows firewall warned about Conficker.C. Downloaded Conficker cleaners, they found nothing.

Booted into safe mode, checked startup with msconfig and exiap6415386.exe was there. Removed it and also svchost which was added to startup, but it wasn't there previously as far as I remember. Is my svhcost infected? >:-/

Now things seems okay, but I checked online exiap6415386. It is some new variant, antivirus tools don't even recognize it yet apparently.

Update: Spybot says it's SmitFraud.C Or is it a different one which also creeped in? :P

Update2: Make sure you always have a Live CD at home for situations like this, so you have a clean system to get info from the net about removing the badware. Using the infected OS is not a good idea. I used an Ubuntu Live CD, but any other will do.

Also, check out the comments here. There is good info there.

Importing large mysql database dump into Godaddy shared hosting

2009-08-31T04:14:00.000-07:00

So, you have a database dump which you want to upload to Godaddy? There is the Import tab in phpmyadmin, but it often times out for big files, so it's not really good. Luckily, there is a better way using FTP:

Upload your dump with FTP into the _db_backups directory in the root of your hosting account. Then go to hosting management, databases and click on the pencil icon beside the database into which you want to pump data.

Then check out the icons on the top. Select Restore and you'll see your dump file there (possibly you have to give it a .sql extension, I used this extension in the first place).

Next select the file and start the restore. A warning will pop up saying the existing database contents will be lost, but don't worry, it happens only if you restore a complete databse dump with dropping tables and stuff. If your dump contains only insert statements and such then existing data won't be harmed. You can always create a database backup first in database managament if you want to be on the safe side.

The uploading of the dump may take a while, but that's it. I don't know why Godaddy doesn't have this description in their support pages. It's very useful.

Convert jQuery selector result to DOM object

2009-08-02T12:45:00.000-07:00

Why Google Wave can be bad for freedom of speech

2009-07-16T01:52:00.001-07:00

I'm really excited about Google Wave and can't wait to see how it will work in every day life. But one aspect of it is a bit worrying.

I don't know if you have read 1984. In that book the government is constantly rewriting the past publications (books, newspapers, etc.), so they always seem like perfect predictions at their time proving to the government is always right.

In Google Wave waves are stored on the server and clients are immediately updated when a Wave is modified. Suppose a news organization switches to Google Wave from traditional websites. If it happens then they can constantly tweak their publications, suppress unwanted thoughts from their articles if they prove to be controversial, etc. It would be a true 1984 world: the readers would always see fixed articles and they could not tell if it was the original article or a modified version.

Sure, a Wave has a version history, but it may require special privileges to access and it could even be modified.

Wave is a wonderful tool, but I wonder what such a world look like where the government mandated using Google Wave, so it can constantly tweak its propaganda.

How to get a new IP address

2009-07-01T08:56:00.000-07:00

Sometimes you want a new IP address. For example, if you are especially naughty and want to download too much stuff from Rapidshare then it blocks you if you are over your limit.

Don't despair! If you're on an ADSL connection then you can easily get a new IP address by disconnecting and reconnecting. Provided your ISP is set up this way, but it probably is. Try it.

In the Advanced settings dialog you can change the color of any part of your desktop. Enjoy.

Be a happier clipboard user!

2009-06-23T13:36:00.000-07:00

I wasted lots of time during the years with the clipboard, because I often lost text on it when I copied a new block of text which overwrote the old one on the clipboard.

I heard about clipboard manager programs before, but I never tried any. Until now. Do yourself a favour and try ClipX or any other free clipboard manager.

On less thing to worry about. I'm a happier man since then. :P

Sorting text correctly according to language rules

2009-06-23T02:18:00.000-07:00

Sorting text in different languages into a proper order is a tricky thing. Collation rules can be quite complicated. If you have a static body of text then the simplest way to sort it is by using the relevant Word feature if you are on Windows or Openoffice on other platforms.

So copy the lines to be sorted into world. Select the whole text and choose Sort from the Table menu.

That's it. You can even choose the sort order there.

Finding interesting deleted pictures and videos

2009-06-22T02:40:00.001-07:00

Heard about some juicy thing in the news? Like a scandal or a sex video of a celebrity? You see links in the articles, but they are all dead, because the censors were faster?

Twitter to the rescue! Twitter is real time, so it's hard to censor it. Go to Twitter search, input the desired name or thing and there is a good chance you'll find instantly what you're looking for.

Nifty, eh? The dawn of real time search is a nail in the coffin of internet censorship.

Why Twitter is vulnerable when reporting from oppressive countries

2009-06-17T23:11:00.000-07:00

We hear many stories recently about Twitter used by people in Iran and China to report about issues which the government doesn't want its subjects and the world to know about. Twitter is used very successfully in this fight, but the main problem is the service is centralized, so the government can shut it down and that's it for tweeting.

Google Wave will be released this year and I expect it will replace Twitter for such uses. Why? Because people can run their own Wave servers and those servers can communicate with each other, so there is no central point of vulnerability.

So people run their own servers and they use it for normal communication, but if there is an important event they can use the mesh of Wave servers to distribute information about the event. The government has no central server to shut down, they have to go after each individual Wave server which is much more laborious.

Therefore the future of citizen media is Google Wave, not Twitter. We only use Twitter temporarily until the real thing comes out. Work faster, Google! :)

The reason why PHP Can't connect to MySQL server on 'localhost'

2009-06-17T07:59:00.000-07:00

If you can access the server from the command line with a mysql command issued without parameters then there is a good chance the server is configured to use a local socket or pipe on windows, so you need to specify this socket when connecting.

On Windows it's as simple as this: mysql_connect(".")

Configuring local virtual hosts with Apache/XAMPP

2009-06-17T07:51:00.000-07:00

Add these to c:/xampp/apache/conf/extra/httpd-vhosts.conf:

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot C:/xampp/htdocs
    ServerName localhost
</VirtualHost>

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot path/to/your/project
    ServerName yourvirtualhostname

    ErrorLog path/to/your/project/error_log
    CustomLog path/to/your/project/access_log common

    <Directory "path/to/your/project">
        Options Indexes FollowSymLinks Includes ExecCGI
        AllowOverride All
        Order allow,deny
        Allow from all
    </Directory> 
</VirtualHost>

The second one is your new virtual hosts and the first one guarantees access to non-virtual hosts still work.

You also need to add your new host name to c:/WINDOWS/system32/drivers/etc/hosts:

127.0.0.1 yourvirtualhostname

Opera Unite turns everyone into a pirate

2009-06-16T00:19:00.001-07:00

Interesting announcement from Opera today. Opera Unite turns your browser into an easy to use web server which can be used to shared stuff with your friends and family.

Neat idea, though I don't have my computer switched on all the time, so it's usefulness is limited to the periods when the computer is actually on.

The distributed approach is vaguely similar to Google Wave, but the details differ, of course.

The main problem I see with the approach is the limited upload bandwidth. I'm on ADSL, uploading stuff is slow, so having my meager upload bandwidth eaten by others is not what I want. Could be useful to people with fatter pipes, though.

Nice work, Opera. You showed them once again. :)

How to survive a Gmail failure with only a few scratches?

2009-05-08T03:26:00.001-07:00

Google provides offline access which makes your mailbox available to you even if their servers are down. You won't be able to send mail, but at least you can read the old ones and that's something, isn't it?

Gmail is down again

2009-05-08T03:15:00.000-07:00

Can't be accessed from anywhere. Reports are rolling in from all over the world. It's a bad day to be a Gmailer.

How can I extract and view broken RAR files?

2009-05-08T01:48:00.000-07:00

It's pretty easy actually. Open the file with Winrar and don't worry when it's complaining about an unexpected end of archive file. Just start the extraction and in the extract dialog box select the option Keep broken files. Winrar will extract the broken file, but won't delete it from the disk, so you can view its contents.

If it's a movie file then you can use VLC player to watch it. It is able to play unfinished files.

Enjoy.

How to preview quickly related Youtube videos

2009-05-07T11:25:00.000-07:00

When watching a video on Youtube it's often worth to check out the related videos too. Of course, most of them will not be interesting, so it would be nice if one could quickly watch them without clicking them one by one.

It is possible to do this with a bookmarklet which you can easily add to your browser and activate on any Youtube page.

Click this link: youtube hover with the right mouse button and in the appearing menu select Add to Favorites (Bookmarks). When it's done you can watch any video on Youtube as usual and if you want to see the related videos then you click on the bookmarklet, simply hover over the related links with the mouse and the related video appears instantly in a popup window.

Isn't it cool? Write a comment if you find it useful or you have suggestions.

How to use Google Reader effectively?

2009-05-06T11:32:00.001-07:00

If you read lots of feeds in Reader then the number of items waiting to be read can be intimidating. You know you have to process all news items, because new ones are coming continuously and you'll be overwhelmed if you don't read the ones you have in Reader already.

This is very stressful. I know, because I've been there.

The solution: employ a more casual approach to the reading of news. Collect similar feeds (e.g. economics, entertainment, etc.) into a common folder and use the folder to read all the relevant feeds mixed together. The secret is you don't have to read all items. Just skim the river of news and stop at an item which captures your attention. Don't worry about the others. If something is really important it will come around again.

This way you can use Reader in a more relaxed way. No more stress, more efficiency. :)

How Do I View Full Screen Videos on Youtube?

2009-05-02T03:38:00.001-07:00

My older relatives always complain when watching videos on Youtube that they are tiny and hard to see, and they don't know how to make it bigger. Do you also have that problem?

At the bottom-right corner of the video there is a little picture showing a small rectangle within a bigger one. Just click on it and you watch the videos in glorious full screen.

Much better, right?
