Change control isn’t so bad. With the underlying goal of risk mitigation, good change control can save a network engineer from the dreaded resume generating event we sweat over during cutovers. Change management frameworks such as ITIL layer an element of bureaucracy over network operations to provide a basis for a quantitative approach to IT […]

We’ve recently added video streaming service to Mail.Ru Cloud. Development started with contemplating the new feature as an all-purpose “Swiss Army knife” that would both play files of any format and work on any device with the Cloud available. Video content uploaded to the Cloud mostly falls into one of the two categories: “movies/series” and “users’ videos”. The latter are the videos that users shoot with their phones and cameras, and these videos are most versatile in terms of formats and codecs. For many reasons, it is often a problem to watch these videos on other end-user devices without prior normalization: a required codec is missing, or the file size is too big to download, or whatever.
In this article, I’ll go into detail to explain how video playback works in Mail.Ru Cloud, and how we made the Cloud player “omnivorous” and ensured support on a maximum number of end-user devices.

This week’s comedy gold was listening to a conversation emanating from a nearby inhabitant of our corporate cube accomodations, where one of my colleagues, Bob, was explaining to another coworker, George, the reasoning behind the decision to deploy firewalls to a particular new location.
Roughly summarized, the argument was this:
George, deploying a firewall is like having sex.
(No; I confess I had not anticipated ever typing that particular sentence, and I hope I never have to type it again.)
When you want to have sex, you decide whether you want a baby, and thus you choose whether or not to use contraception. If you don’t use contraception, while there’s no guarantee that a baby will arrive, there’s a real good chance that it will, so don’t be surprised if it does. Contraception isn’t perfect, but it at least reduces the likelihood of having a baby.
I confess I was laughing hard as I listened to the explanation because it’s an inspired analogy. However, buried somewhere in my subconscious was an Australian voice saying something like All these security products are a waste of money. It’s cheaper to save the money you would have spent, deal with a breach Continue reading

For best article visual quality, open Ping on You! – small weekend web/CGI project directly at NetworkGeekStuff.
After a few previous web programming endeavors (both here on networkgeekstuff.com with SDN programming and in real life job) I had a taste to develop “something” and since I am a network geek, I wondered what I have needed in the past as network tools that would ideally be placed on the internet. So I came to the very basic list of things like ping, nslookup or putty as tool accessible only via a browser.
So without more delay, I give you first beta release of Ping on You! – pingonyou.com the list of current features is:
Here is a quick view how it looks when you try to ping google’s public DNS service on 8.8.8.8, since in the background a linux like ping tool is used, you have the same output:
Additionally, here are some features that I plan to do when I get more time, however no release date right now because there are much more complex than the above ones:
For best article visual quality, open [minipost] Windows partition editing with diskpart directly at NetworkGeekStuff.
This will really be a micro-post as I only want to document this for my benefit. This is a way how to change partition table for disks, or USB sticks. In my example, I had a linux live boot USB stick that I needed to quickly convert into a usable storage USB stick with NTFS under windows and of course the visual GUI tools under My Computer -> Manage -> Disk Management was not having full visibility on all partitions that the linux created on this USB stick, so this is how to actually do partitioning on windows.
So without more delay, this is an example how to clean the USB stick partition table and reformat it for windows use:
In summary, short, but hopefully useful minipost for someone.
In the future, will software define everything?
