Bad Code:

Do we not think enough when coding? Do we jump to the first solution without really considering the problem, without trying to analyze and decompose it and understand the components and orthogonal forces involved? Is that the cause of bad code (together with time press) and the reason why we typically see a “patchvolution” rather than evolution (of design)?
For example I want a certain item on my list shown grayed out because it has been marked for removal or is currently being edited and I therefore add a flag called isDisabled. But if I really thought about it, I would likely call it based on the purpose rather than display, e.g. is Being Edited. And I have often observed that I/we tend to jump to the first acceptable solution without trying to consider other, (radically) different and perhaps better alternatives. That is easily explained with our inborn intellectual laziness and we certainly can agree that we should not over think things and that we need to ship but still, shouldn’t we try to think a little more?
The Clojure community has been very inspiring for me in this regard. There is a strong focus on spending more time on the problem than the solution to really understand it, and on separating the different concerns involved and adressing them separately, as well as on achieving simplicity. One of the manifestation is the strong preference of small, focused, composable libraries over frameworks. F.ex. it took couple of years for Clojure to get support for named arguments – but the result – destructuring – is something much more powerful, that now pervades the whole languages (of course, this is a language, not an app). When you listen to Rich Hickey talking f.ex. about core.async (vs. agents etc.) you see that the man thought deeply about the problem, alternatives, and their pros and cons.
May be we should spend little more time with our problems before jumping to solutions, no matter how much we like to solve things. Perhaps we would end up with a much better code than we typically have, and thus considerably lower maintenance costs.

Top 5 Affordable Web Hosting Companies in Pakistan

Pakistani bloggers and website owners usually face difficulty in finding a good web hosting company for their online business. One of the biggest reasons for this difficulty is the unavailability of PayPal in Pakistan due to which bloggers and website owners from Pakistan unable to purchase international brands. It doesn’t mean that you will fail to get a good web hosting in Pakistan. There are some top hosting companies where you can avail quality services at affordable prices.
All Pakistani web hosting companies sell the hosting of international brands. Due to energy un-stability and unavailability of ultra fast Internet connections, it is impossible to maintain local servers. Now while selecting a web hosting company in Pakistan, we need to know that where the servers are located at which the company is offering hosting for your blog or website and what is the reputation (it tells the performance of the company) of the company among customers.
Since 2004, Navicosoft has grown a lot. With US based servers, the company is providing quality web hosting and domain registration services to its clients at very affordable prices. I have been using the hosting services of Navicosoft for one of my websites and found it brilliant. Uptime of the servers is almost 100% and your site will perform faster on shared plans with Navicosoft than any other company. In addition, support of the company is also brilliant and you will get instant help whenever you will face any issue with your website or blog.
The one and only drawback of the company is that it doesn’t provide unlimited domains for hosting packages. i.e. if you purchase the unlimited hosting with Navicosoft, you can use only one domain with it. If you don’t have more than one blogs or websites, Navicoft is my first recommendation for your online business.
HosterPK is yet another fast growing web hosting company in Pakistan. Most servers of the company are located in Germany. The company offers the cheapest hosting in the country. Support will also satisfy you and you will be helped instantly whenever you need assistance. The flexible plans at HosterPK allow you to choose a suitable package according to your blog or website’s need. 
Our next recommendation is Nexus.net.pk‘s hosting services at which you will find brilliant web hosting features at affordable prices. The company is serving Pakistani bloggers and website owners for a long period of 14 years since 1999 and it has a large number of satisfied customers. These stats show that Nexus is really doing well in filed of web hosting.
CreativeOn.com is operational since 2001 and is providing quality web hosting services to its clients at affordable prices. Not only in Pakistan, the company has many satisfied customers from all over the globe. You will also find it a perfect choice for your online business as others do. 
Our last recommendation is Cyber.net.pk‘s hosting. It is among the oldest web hosting companies in Pakistan. Cyber.net.pk is providing hosting services since 1996 and has a good number of satisfied and happy customers.
These were top five web hosting companies in Pakistan. The list doesn’t end here, there are many other good web hosting companies also about which I don’t know a lot, so I restricted my list to these five hosting companies. If you have any suggestion, then don’t forget to share with us by leaving your comment below. Thank you!

Q.Horrible stomach pain when hungry?

If I go too long without eating, I get a stabbing pain in my upper abdomen, It goes away after eating. I had my gallbladder removed about 7 months ago.

A.You may have a duodenal ulcer, or the start of one. I guess the best treatment, if you want to call it that, is not to go too long without eating. In ulcer patients, an empty stomach is conducive to pain, since the hydrochloric acid in the stomach can make it feel raw and painful. There was a time when doctors recommended a bland diet and drinking milk, but nowadays, they say you can eat anything you can tolerate. Avoid excessive caffeine and alcohol, as they are irritants. Same goes for nicotine. There are a number of OTC remedies for hyperacidity, such as Tagamet, Zantac, and Prilosec. Your doctor can write you a prescription for stronger versions of these drugs. They can be extremely helpful in either neutralizing excess acid, or preventing the flow of it. Antacids, like Tums or Rolaids are also helpful, but should not be taken with the medications named above. If symptoms persist or get worse, then see your doctor by all means. Good luck!
