Run your downloaded files directly from Firefox using Opendownload

If you have used Internet Explorer, as I have once did. You may know that there is an option to execute or run a file, usually a setup file directly while downloading. i.e The file will be downloaded to your temporary directory and it will be executed directly from there. The nice thing about this is that you can keep your downloads directory clean, void of any clutter from excessive downloads. The downloaded files will be deleted after 24 hours.

This can be implemented in Firefox also, with the help of Open Download extension. Especially useful if you want to install an application directly, without wasting any time or maintaining the files in your hard disc.

I today found a guide on how to keep your Ubuntu installation in perfect shape. It advises you on how to get rid of “orphaned” packages, unnecessary local data, and some more.

Tips for solving Crosswords

Crosswords are very interesting, if you love words. It is a cool way to kill time when you are on the bus, waiting for a plane, OR in a restaurant. Here are few tips you can use to figure out how to solve a puzzle.

  • Start with what you know for sure and build from there. Short answers are usually easier to get than longer ones, because the English language doesn’t have many three- and four-letter words, and the same ones tend to appear often in crosswords. This is especially so for words with lots of vowels, like ALE, ARIA, and OLEO
  • Remember that a clue and its answer will always be in the same part of speech and generally can be used interchangeably in a sentence with the same meaning.
  • If you get stuck, don’t be afraid to guess. But also don’t be afraid to erase an answer that isn’t working out from the crossings.
  • If you really get stuck, put the puzzle aside and come back later. It’s amazing how often this trick works. Thinking of one new answer the next time around may be enough to get you off and running again.
  • Finally, to answer a question I’m asked all the time: No, it’s not “cheating” to use a reference book or the Internet to get an answer you don’t know. It’s your puzzle. Solve it any way you like!

How to reduce the size of Adobe PDF documents

I have a collection of articles that I collected throughout the years and converted to pdf documents. But recently I have to send some of them to my friend, being on dial up, I know that it will be a messy business if I try to send them without trying to reduce the size of the documents.

Use the Save as command instead of Save

This is No. 1 suggestion for reducing the sizes of  PDFs. After you make any changes to your PDF, select Save As, instead of just Save, this will overwrite the entire PDF. Otherwise, if you just click Save, changes are appended to your file, and you’ll notice a slow and steady accretion of kilobytes.

Use the PDF Optimizer

By selecting Advanced > PDF Optimizer > Audit Space Usage, you can find out which elements in your PDF (fonts? images?) are taking up the most space and make changes accordingly.

Reduce Graphics and Images

We all knew that image files takes many times more the disk space than text. So reduce them or use optimized images, if necessary.

Vector-based graphics scale perfectly, look better and take up less space than their GIF counterparts.

If you have to insert a graphic as a bitmap, prepare it for maximum compression and minimum dimensions. Don’t compress the graphic beforehand, because distilling them in the PDF may cause the creation of noticeable artifacts in the image.

To experiment with the image compression quality to size ratios, select Advanced > PDF Optimizer, and on the images tab select compression options for color, grayscale, and monochrome images. Or, select Enable Adaptive Compression and drag the slider to balance file size and quality.

Use RGB colour

PGB uses less space than CMYK, so if you are not intending to print the documents in high quality it is recommended to use RGB than CMYK

Use Minimum fonts

Fonts use space, try to use minimal space and don’t embed many fonts as this will increase the size of the document considerably.

Use latest Acrobat

Use the latest version of the software, as there will be minor improvements in the compression algorithms that may help you to achieve the desired results. an example Acrobat 5 (PDF version 1.4) introduced JBIG2 (Joint Bilevel Image Experts Group) compression, which is superior to the CCITT or Zip algorithms that previous versions used when compressing scanned monochromatic copy. Most PDF users have made the switch to newer versions of Acrobat, but if you’re still using an old copy, it may be time to make the switch.

Use special Software

There are specialized software that can reduce the size of the document. Here are a few links that may of help.
