Twitter spam phishing continues

Published by:

twidowThere is a new Twitter phishing scam making the rounds, and this one is spreading quickly via direct message, wrote by Ben Parr on in October.

Indeed, when using Twitter, I have noticed a lot of DMs in my inbox containing weird messages accompanied by a short URL. Twitters @SPAM acount wrote a few days ago: Getting weird DMs? Probably due to phishing. Don’t go to the links sent in the DMs or give out your login & PW! It seems like the problem is spreading.

The phishing and spamming on Twitter is going on since January! Typical messages look like hi, find out if your iq is higher here http://pei**** or you’re on here lol http://v*** They know just how to get you curious enough to click the link, so it’s best to refrain from clicking any link in your DMs for a while. The link takes you to a Twitter login page. If you enter your password, rogue spammers abuse your twitter account to send private messages to you followers, possibly infecting them too. So don’t do it!

If you think some application is sending DMs in without your permission, look to revoke the permission rogue apps have at and change your password at

Twitter says: We’re working to reset PWs and notify users w/affected accounts in the meantime (but feel free to change your PW if worried!)

How to make a high quality MP3

Published by:

Making the perfect MP3 is still a challenge. When looking for an MP3 encoder, the software that creates the MP3’s, you’ll find an abundance of programs available. But not all of them get the job done.

In this edition of “make a high quality MP3” we go for encoding WAV files into MP3s using the LAME MP3 encoder. This encoder is widely accepted as the best free alternative for expensive commercial encoders. It’s very fast, it produces high-quality files and has many advanced features.

Unfortunately LAME is a command line utility. To get the familiar graphical user interface, we need a front end. A front end is a piece of software that communicates between you and a command line utility through a graphical user interface. Razorlame is exactly the software to get this done.

Setup is easy. Download Razorlame and extract it to a folder. No additional setup is required. We included a recent version of Lame.


Now that’s done, let’s see at some basic features of Razorlame. RazorLame should be quite straightforward. LAME offers a great variety of options, so does Razorlame. To find out what an option does, hover with the mouse a few moments over the control and a hint will appear (most of the time).

Encoding settings:



  • Bitrate:: The higher the bitrate, the better the quality, but higher bit rates create larger files. Also note that not all devices can cope with hight bitrates. I suggest to use 128 kbit for portable devices, 192 kbit for car MP3 players and 256 kbit for archiving. The difference between 256 and 320 kbit is unnoticeable for 99% of the listeners.
  • Mode: Choose between stereo or mono. Joint stereo gives somewhat smaller files, but it distorts the stereo image.
  • Output Directory: Choose between storing the resulting output in the same directory as the source OR point the output to a specific directory.



  • Optimization: Choose between speed or quality. Quality is slower, while speed results in (somewhat) lower quality.
  • Include CRC Checksum: Check this if you want some protection for bit errors. It makes the files larger. CRC does not protect for large errors, some believe CRC prevents corrupted MP3’s from playing all together, while without CRC the files plays, even when there is some minor corruption. I suggest you leave it unchecked.


Variable bitrate (VBR) files vary the bit rate in function of the complexity of the sounds it needs to encode. The advantage of VBR is a better quality-to-space ratio compared to a CBR, but the encoding is more complex (slower) and the results are incompatible with some hardware.

  • Maximum Bitrate: This is the maximum bit rate a segment can have. If a passage of music is very rich (high frequencies) it will switch to this bit rate during that passage. When the music becomes less complex, the bit rate drops to a lower rate. You can set the lowest bitrate in the general tab. I suggest setting this to 256 kbits and de general tab bitrate to 128 kbits.
  • Quality: When using VBR this setting sets the overal quality/speed, where 0 is highest quality and 9 the lowest. I recommend 4. Look at this table to see the different results for different settigs:
  • ABR: ABR is variation on the VBR-style distribution of bitrate, but subject to an overrall target bitrate, rater tha an overall target quality irrespective of bitrate. Some hardware isn’t compatible with ABR.

Leave the Expert and Compression tabs as they are for now.


Let’s encode a WAV file. It’s the kind of files you’ll end up with extracting audio from CD’s. The process is very simple. Just drag & drop the wav file into Razorlame. Then click the ENCODE button. You can drag multiple files to Razorlame.


There you are. You now have a high quality MP3.

Left click folder freezes or hangs explorer

Published by:

This is a troubleshooting post.

Windows explorer may stop responding when left (or right) clicking a folder. The explorer is freezing or freezes for some time, typically 30 seconds. After that you can access the folder. Attempts to close the folder while the hourglass is turning results in an error or message “This program is not responding”. You can either end the process, after which explorer restarts, or cancel.

In my case I found windows looking for Network Drive letters. I noticed that using Procmon, a process monitor.


Just after the explorer had touched a .lnk shortcut file.


It seemed windows, when clicking the folder, looks trough all the files and then discovered a shortcut to a network drive that doesn’t exist. It was an old shortcut pointing to a fileserver that doesn’t exist anymore. The query typically times out, but that takes a while.

The problem was solved by removing (deleting) the shortcuts.

Is your WordPress affected by a virus?

4 ways to find out if your WordPress installation has been affected by eval / base64_decode | Digitizor
Many websites including Lorelle and Techcrunch are reporting a new kind of attack on WordPress that affects almost all WordPress installations running WordPress software below version 2.6. All those running WordPress version 2.8 are not  affected.  Users having blogs on have not been affected, although. In this article we will tell four ways which you can use to find out if you have been affected.
