Playing with images can be lots of fun with Fotosketcher, throw the right photo through this program and you can create a professional image that would look great printed and framed or make for an admirable desktop computer wallpaper.

Fotosketcher review conclusion

One of Fotosketcher’s drawbacks is that it can only save images as a .jpg, .bmp and .png, not the best format for printing and mostly suitable for Internet usage of the photographs. I hope this photo editor can support more graphical formats in future releases because other than that I quite liked it.

This way to convert a digital photo into pencil sketch or painting canvas should satisfy most home user needs and it makes for a free, if somewhat limited, Photoshop alternative.

Methods to find out if your ISP is throttling your bandwidth

Bandwidth throttling and traffic shaping happens when a network attempts to limit the amount of bandwidth that a given service or user may use. Many ISPs terms and conditions specify a maximum data download per month allowed but they are not too keen to tell you about it when you sign up with them.

Citing bandwidth abuse from a few users some ISPs will sneakily throttle the Internet speed for users they claim to be downloading too much data, this bandwidth throttling is mostly used against P2P software protocols as P2P software is notorious for its bandwidth usage, technically bandwidth limits could be imposed to any application and it is often used for people on mobile Internet tariffs.

If you observe your Internet speed has ups and downs frequently or peer to peer applications do not reach the same Internet speed that your browser does, chances are that your ISP could be rate limiting your traffic for certain bandwidth intensive operations or at peak time.

How to test if your ISP is limiting Internet bandwidth

Nealyzr: Online test that analyses your overall Internet connection, it can detect an ISP slow DNS server, blocked TCP and ports, IMAP, SSL diagnosis and much more. You will have to allow Java to run in your computer, which could be a security risk if you don’t know the source. The project is backed up by the University of Berkeley which is a trust worthy entity.

Switzerland Network Testing Tool: This open source tool has been developed by the Electronic Frontier Foundation and it will test the integrity of data communications over networks, ISPs and firewalls. This traffic shaping test will spot IP packets which are forged or modified between clients, inform you, and give you copies of the modified packets.

NOTE: The Switzerland Network Testing Tool only works from command line, to be used by advanced computer users.

Glasnost test: To perform this Internet traffic shaping test you will need Java installed. The Glasnost test can detect bandwidth throttling in P2P software, Email, video streaming and even Usenet traffic shaping.

This traffic shaping test uses a Java applet to compare your regular download speed against the speed at which Flash videos get streamed to your system. It can also compare the download speed for email attachments (via POP and IMAP), normal HTTP based file transfers, torrents and binary downloads from Usenet servers.

The Glasnost test will create a fake data stream between your computer and their servers and then monitor the data packets flow.

Measurement Lab: M-Lab is a multi-functional internet performance measurement tool supported by Google that includes numerous online tests to check your Internet connection reach, ideal to troubleshoot Internet network problems.

Neubot: A research project that checks network neutrality is being enforced. You have to download their open source client for Windows, Mac or Linux and run it in your computer, the program will perform a series of tests in the background using the distributed Measurement Lab platform to find out if any kind of throttling is taking place. Data is collected by the University of Torino to carry out an study on Internet providers that throttle bandwidth.

How to run a traffic shaping test

Some Internet Service Providers only limit Internet speed at peak times, if you suspect your ISP is limiting your bandwidth consider carrying out various tests at different times and make sure that there are no other processes running in the background before performing the ISP throttling test.

What your credit card numbers mean

Every time you enter your credit card number into a form the credit card processor will perform a series of security checks based on the information that those numbers give away.

Credit card numbers are not randomly assigned, each digit in the number sequence has a meaning. Some companies like department stores and phone companies have their own numbering systems, but ANSI Standard X4.13-1983 is the system used by most national credit card systems.

Credit card number length will change depending from issuer, the most usual is 16 digits divided in groups of 4.

Credit card number length

The first credit card number will always be 3, 4, 5 or 6 and it is known as the Major Industry Identifier (MII), this number represents the entity which issued your card.

  • American Express: 15 digits
  • Visa: 13 or 16 digits
  • Mastercard: 16 digits
  • Discover: 16 digits
  • Diner’s Club/Carte Blanche: 14 digits
Credit card number codes by issuer

Meaning of the credit card first digit

American Express and Diners Club credit cards also use a second digit to identify the company. Diners Club cards will start with either 36 or 38, and American Express cards use 34 or 37.

The rest of the credit card digits meaning will vary depending on credit card type and issuing company. Normally the numbers grouped after the opening series are the routing number of the bank and the next group of digits represents the user’s account number.

  • Number 3: Travel and entertainment cards such as American Express or Diners Club.
  • Number 4: Visa credit card and Visa branded debit cards.
  • Number 5: Mastercard credit card and Mastercard branded debit cards.
  • Number 6: Discover credit card.

The other credit card numbers explained

  • American Express: Digits three and four are type and currency, digits from five to eleven are the account number, digits from twelve up to fourteen are the card number within the account and digit fifteen is the check digit.
  • Visa: Digits from two through six are the bank number, digits seven through twelve or seven through fifteen are the account number and digit thirteen or sixteen (depending on credit card numbers length) is the check digit.
  • MasterCard: Digits two and three, two through four, two through five or two through six are the bank number (depending on whether digit two is a 1, 2, 3 or other). The digits after the bank number up through digit fifteen are the account number, and digit sixteen is a check digit.

The final credit card number is a check digit, a checksum number calculated using the Luhn algorithm and used for fraud check purposes.

Credit and debit card security code explained

Credit and debit cards also contain a credit card verification code that it is known as CCV, CSC,CVC2, CVV2, CID2 and many other acronyms depending on who the credit card issuer is.

  • MasterCard, Visa, Diners Club, Discover, and JCB credit and debit cards have a three digit card security code printed at the back of the card but the latest US MasterCard and Visa cards feature this code in a separate panel to the right of the signature strip to prevent overwriting of the numbers when you sign the card.
  • American Express cards have a four-digit code printed on the front side of the card above the number and they call it Card Identification Number ( CID).

The credit card verification value is normally used for card not present transactions, like shopping over the Internet or buying items by mail, credit card regulations state that this number can never by stored by the merchant making it more difficult for a thief to get hold of it.

The card verification value at is calculated by encrypting the bank card number, expiration date and service code using encryption keys known only to the issuing bank, the end result is the three of four digit decimal number printed on your card.
