Microsoft is buying Github

It seems that Microsoft is buying Github for about 7.5 billion USD worth in their own stock.

Is this a good thing or a bad thing? Probably no reason to celebrate, but Microsoft under Nadella seems to run a totally different strategy than Microsoft under Steve Ballmer. Selling licenses of MS-Windows and MS-Office is probably still a good business, if done efficiently, but it cannot be the future of a company of the size of Microsoft. The dominating operating system is now Linux, mostly due to cell phones and tablets running Android, network devices and of course servers. The religious rejection of open source, as it was propagated by Steve Ballmer, is no longer visible. Some MS-Projects like C# and F# have in large parts or completely become open source and on the MS-Azure-platform virtual servers with Linux and PostgreSQL can be chosen, with the limitation that there seems to be a need to have an MS-Windows-box with dedicated software to manage the Azure cloud services. If we ask Richard Stallman this is probably all tactics to achieve bad goals by harming the free software movement. This can be true or not.

But we no longer have to automatically assume that this acquisition is bad. Most likely Github will continue to operate as it did before. Nadella will not shut down Github, while Ballmer might have done so, maybe. He would not have bought Github anyway for so much money. The real asset of Github as well as of LinkedIn and Skype for Microsoft might be the large collection of high quality identity data. Today Google and Facebook have identity data for about two thirds of the adult world population by my estimation. We see it in action when we find a „login with Google“ or „login with Facebook“ option for a web site. Yes, „login with Skype“, „login with Github“ and „login with LinkedIn“ would also be possible or even exist. This is the spot were these acquisitions might or might not be seriously negative. But increasing the pool of identity data makes a lot of sense for the new strategy of the company and I would assume that it was one of the major reasons for this acquisition of Github as well as Skype and LinkedIn before. Is it worth so much money? If the answer is quite obvious, we will probably know in the future.

Source Code of Apple-iOS leaked

It seems that the parts of the source code of Apple’s iOS 9 have leaked via github. They might have been removed from there, while you are reading this, but probably they will be passed around in the internet anyway.

Some sources say that this is a risk to security. It might be, but in the end cryptography specialists tend to consider the availability of the source code as an advantage for security, because it can be analyzed by everyone, vulnerabilities can be found and published and of course more easily be corrected if the source is available to everyone. Hiding the source code is some kind of „security by obfuscation“, which is not really a strong mechanism and it should be based on verifiable secure mechanisms, as successfully applied by Linux and other open source operating systems. But this might not be fully true, if the sources are just passed around in somewhat closed circles and not easily available to the general public.

This does not make iOS open source, because the licenses that Apple imposes on their software are still valid and to my understanding they do not make this part of the system open source, which means much more than just being able to read the source code of a certain version that might already be outdated. Please observe that if the source code that you might find on github is really coming from Apple, their original license and not the one mentioned in github applies.

To put Jail breaking somewhere near security breaches is wrong, because this is an action done by the owner of the device with his or her own device at own risk. This should be everyone’s right to do so and there should be nothing wrong with making it easier. I know, we are not living in a perfect world…

So please relax. If Apple has done a good job, there will not be too bad exploits and if they are still doing a good job, they will quickly fix any exploits that show up. And if you like to have an open source system, you should still consider using something else.
