Programming Enterprise Application in Perl - 00

SellerBay is a software package I have been developing part-time over the past 1 year. It's aimed to help online sellers make their sales activity efficient and as automated as possible. The commercial motivation comes from prospects of growth of online sales, and the impact that is going to have in reorganizing traditional sales-channels.

Perl is the lingua franca, which I mainly chose because:
  • I am familiar with it from past projects of developing network (LAN, 802.11) appliances
  • From the good things I read about how portable it is.
  • It's age, the "old-wine" status. I just felt better going for something that's been around since so long.
New languages like Ruby, Python etc as well as commercial spins like J2EE, .net were other options that crossed the decision table. .net was easiest to rule out, coz we all know from experience that stuff from the Microsoft-house-of-shit-software-sold-by-genius-marketing-campaigns is best to keep fingers off.

I've read a lot of good things about Ruby, Python and other new languages and how web-app developers are falling in love with them, but having writting 0 lines of code in any of them and SellerBay's objective of being a market-ready ASAP, I shied away from the adventure of getting into them from the scratch.

J2EE was the other other serious alternative, which I am not totally unfamiliar with, but here again Perl won out on portability and age.

I haven't forgotten PHP - features are super fast to accomplish and programmers are abundant whenever I need some coding support. But I stayed away from this given the fact that SellerBay is an Internet based app and security could be my nightmare when the code grows to a sizable amount.

Why is portability important for me? It is because I'd like to keep the flexibility of moving the production, development or staging environments between machines as fast as cafeteria lunch gets served on a weekday. This gives me the advantage of modifying the application environment at will, which I may need to do often till a really stable 1.0 version makes the first dollar.

Why is age important? Mainly because of support. Indeed with Perl I have a luxury of going up to and typing in any keywords like "pdf reports" or "date calculation" or "templates" and find a selection of packages ready to be installed, evaluated and adopted into the application.

So far it's been very rewarding to have banked on Perl, which means I am able to get the features I need without major overheads of time or cost. I am consious of the fact that I might be writing some 20% extra code in implementing certain functions where other langs have them built-in, but it doesn't bother me at this point.

In the long-term I would consider having made a correct choice if these requirements are fulfilled.
  • Performance - The app needs to perform at speeds ala Google, and definately not at those of Paypal and ebay. I am aiming at 1000 simultaneous users
  • Application growth - SellerBay is destined to grow in features as demand for them rises over the years. We also need to make sure that it is prepared to be offered in multiple-languages and look & feel issues (which are at the front-line to customers) can be resolved quickly.
  • Security - There isn't much room to allow for an attack, because it will of course mean loss of revenue and reputation, but I fear it is also going to be difficult to recover from an attack given the minimal resources available to pull this project off.

Paypal's Ridiculous Business Practices

In Q3-2005 we discovered the power of online sales and started to market Wapsol's products extensively online. Just as importantly we decided to get into the trading business for WLAN accessories (antennae, cable, connectors etc) which entails buying from manufacturers and selling on online-retail. Needless to say ebay's 26 worldwide markets were lucrative points of sales.

We used Paypal for collecting most of payments from customers outside Germany. The numbers ticked up fast and we were hecticly building up infrastructure for shipping, online-support, product-portfolio and payment-systems.

One morning as I woke up in Germany I found that Paypal decided to lock up our account without any specific reason. There were no disputes or complaints from buyers or anything that suggested provocation. They just locked it. In it a few thousands of dollars of cash-flow and the account was listed as a favored payment option for some 100 pending auctions - now customers couldn't pay for …

SnagIT Problem Solved! (Hangs for minutes)

Here's the solution to the SnagIT sluggishness (hangs for several minutes)
I would try first turning off the magnifier window under tools > program preferences > program options. Uncheck the box to show magnifier windows. Click apply > ok and then try the capture again.Check your security software and make sure that Snagit is set as a safe application. A security program that consistently scans the process will cause a very slow response like you are seeing.Please also check your printers per this article:Answer Title: Slow SnagIt startupAnswer Link:, please review the steps here and try these as well:Answer Title: SnagIt crashes or hangs when launchedAnswer Link: me know what happens.
