Experimenting with HTTP services – UrlEcho and UrlReq

Posted by jpluimers on 2015/04/16

Interesting, especially the reasoning behind them:

UrlEcho permits the requestor to completely define the response it wants to receive, thus giving it the ability to “host” static HTTP resources within URLs themselves. Why is this cool/useful? #

  • You don’t need a Web server to host a simple resource — you just construct a URL and you’re set to go.
  • Since resources are cheap to create and throw away, you can create as many URLs as you want, when you want them.
  • This is especially useful for testing — you don’t want to configure many server-side resources to return hard-coded responses in order to test correct handling of that response. For example, imagine you need many simple iframes to test a JavaScript library, and you don’t want to modify the server hosting the iframes each time you add or change tests. Since you already know what the responses will be, why not define them in the requests and have a simpler testing process? It makes tests easier to maintain no need to modify the server and understand due to response visibility in the tests.

UrlEcho [ed: UrlReq] lets the requestor to wrap any HTTP request any method, with headers and body into a simple GET request with only an URL defined. Why is this cool/useful? #

  • You can make any HTTP request in situations where only a simple GET is possible, or where you can only define just the URL. For example, most systems that provide Web hook callbacks only let you define the callback URL only not the method, headers or body structure.

Mobile Scanning Apps: A look Into The Dark Side By: Joe C. Hecht – Code4Sale,…

Posted by jpluimers on 2015/04/15

Summary of the dark side:

Every app we tested saved the image in a grayscale JPEG format. Simply put, you scan your document, save it in “space saving” monochrome, then the app up-samples it to a now “space wasting” grayscale format, dials in a low quality lossy compression ratio to make you think you are saving space, and thereby throws away some of the pixels in your scan.

A very interesting read by Joe Hecht. Nothing new for old FAX, TIFF and PDF farts like me. Entertaining and hopefully teaching for the newer generations of software developers.

So if you ever do PDFs of paper scans:

  1. use monochrome
  2. use loss-less compression
  3. look at what FAX machines did back in the days for pixel perfect legal proof documents
  4. know about PDF/A

Now that XE8 is out, some Turbo Pascal history

Posted by jpluimers on 2015/04/14

A few people asked, so below is a picture of just a piece of my books closet.

From left to right:

  1. Object Professional 1.0 manuals volume 1-3
  2. BTree Filer 5.0 manual
  3. Turbo Professional manual (from 1985!)
  4. Borland Paradox Engine 3.0 manuals
  5. Crystal Reports Developers Edition
  6. Borland Open Architecture Handbook for Pascal
  7. Turbo Pascal 5.5 OOP Guide
  8. Turbo Pascal 5.5 Reference Guide
  9. Turbo Pascal 5.5 User’s Guide
  10. Turbo Pascal Quick Reference
  11. Programming with Turbo Vision

This is only the front-left portion of one shelve. Most shelves are two deep and about 4 times as wide as what you see here (:

I have floppies somewhere in my archive too. Need to dig them up some day.

Batch file that finds and starts Cntlm.exe in verbose mode.

Posted by jpluimers on 2015/04/13

As a follow up on the Cntlm configuration post last week, here is a small batch file that will find Cntlm.exe (on x86 and x64 systems) then start it in verbose mode.
