SEO investigate HTTP server responses

in SEO

As of 2014, there are plenty of tools that allow observing HTTP traffic from and to your browser. As a default, nowadays browsers come with an integrated Developer Tool offering – among many things – a visual interface for such tests. Why is valuable investigating the HTTP connections? From an SEO standpoint, this investigation proves to be helpful while debugging Ajax problems and Flash apps connectivity issues. Similarly, it may be necessary investigating the cause of a redirection chain, or the HTTP response returned when users hit a resource. It is not a surprise (not anymore) the fact that many sites – although very expensive – have many underestimated technical issues simply because coders have no clue of what the web and the Internet foundations are. For instance, one of the most common mistakes I encounter is non-existing URLs returning a HTTP Status code 200 instead of 404. Similarly, resource rarely (or never) changed that return an Expires header too far into the future thus suggesting browsers not to request the resource […]

Combining multiple CSV files with your Mac OS X

in Tips

If you have ever used a Windows or Dos based system, one thing that you may have appreciated is the possibility to use wildcards while searching for files and directories. Unfortunately, this opportunity it exists on Macintosh, but you have to remember to specify the exact path where you are looking for the files. Failing in this, LS will nastily command prompt the syntax string to use that is even useless. Assuming you are in the folder where all your files reside, to selectively return only some files corresponding to certain criteria you have to type something like ls ./*yoursearchstring* Clearly ‘yourstring’ need to be replaced with the string you need, but pay attention remove the quotes. I’ve written a Python script to generate a series of file for me, and in my circumstance the files are generated in a timely order. Let’s say I need to order my files from the most recent to the […]

Open multiple instances of an application in OS X

in Tips

Nobody wants to run multiple instances of a program at the same time, and I don’t want it either. And Mac OS X is doing a great job for this as by default it is designed to handle software in a single-instance launching allowing the user to have it only once at a time.  As long as the software has a nice “Window” function and it supports floating windows, meaning that you can align the windows in two different places and makes comparisons if required, this is absolutely fine.I’ve seen the majority of the Mac software I need to make this possible. However, there are particular applications – normally Java/based – that don’t make this possible, and this really made me mad. So, I did run a couple of searches and here we go, a pretty neat solution that will make the word “instance” at the top an easy game. How? This requires you to be […]
