Anyone that tried to cache static files eventually got to a point where cache caused more problems than it solved. After all, telling all your users to press Ctrl + Refresh in their browsers is not exactly how one should do things on the web. Two years ago Mads Kristensen presented us with a solution […]
A few years ago, I wrote a post on why I don’t trust 3rd party APIs. It has never been more true than today (in days of NuGet, npm and other package managers) when adding an API is a matter of seconds. Seriously, you don’t even have to break a sweat. Package managers and web […]
In olden times, when I did C and C++ development, memory leaks were a common thing. From time to time I still wake up from nightmares in which I debug, trace and try to locate and plug memory leaks (of course, as this is nightmare, I fail to do either, or it wouldn’t be a […]
At work, I got a short task of extending a varchar column in our database from 25 chars length to 50. The task seems easy enough. But, as things usually turn out, it contained a GOTCHA! The column was also a part of primary key on that table. Thus, I started to wonder. Can you […]
In 2013 Forbes reported that approximately 30,000 sites across the globe are hacked each day. Yet, for some odd reason, in 2015, I still see web applications that employ questionable password storing mechanisms e.g. storing passwords in plain text or just hashing them with md5. With 30,000+ sites hacked a day, there is a strong […]
Recently, I started to learn how to do mobile apps. Instead of classic ToDo app, that everyone is so fond of, I decided I will do a bit more realistic application. It would include, for starters a first time initialization, that would run (what a surprise!) at first run of installed app. This initialization would […]
This might be a bit of a d’oh, but if you decide to handle exception, handle it properly. What do I mean by saying “properly”? Have you ever seen code like this? var myClass = new MyClass(); try { myClass.SomeMethodThatCanThrowException(); } catch { } finally { myClass.Dispose(); } This code is stupid. Exceptions are a […]
In asp.net world, creating custom server controls has become some sort of a standard. In fact, it is so easy to create a server control, that developers usually do it without thinking. The problem is, that server controls are a bit more complex than an average Joe would think. There are bunch of things you […]
I don’t know about you, but I still have a vivid memory of the time before internet actually became useful. In those days, learning how to solve your problem included a lot of trial and error attempts and eventually a trip to local library. If finding a book on correct topic wasn’t enough of a […]
The easiest way to obtain serial number of a certificate is to go to Internet options -> Content -> Certificates and double click the desired certificate. In the Details tab, there is a property list control with a row containing “Serial number” label in first column and value in second. When you click on it, […]
