Universal Android ADB driver for Windows – koush/UniversalAdbDriver

Posted by jpluimers on 2015/11/17

If you ever need a universal Android ADB driver for Windows, then use this one: koush/UniversalAdbDriver.

I never noticed it was there until Koushik Dutta posted about a signing trick on Google+.

Windows drivers need to be signed, so what he does is generate a self signed certificate on the fly during installation, sign the driver install it, and drop the private key of the certificate.

Each installation has its own key, Microsoft is happy, and it is proven the driver signature mechanism in Windows has a hole.

If you want to do similar things, then this commit is what you are looking for: Use a self signed, self destructing signing cert. · e8b78fe · koush/UniversalAdbDriver.

It isn’t rocket science, but not trivial C# either, so this is a great example of something that works.

Inno Setup: Program Folder not showing up In Start > All Programs. I’ve been…

Posted by jpluimers on 2015/11/15

taskkill /f /im explorer.exe
del %LOCALAPPDATA%\IconCache.db /a
start explorer

Source: Inno Setup: Program Folder not showing up In Start > All Programs. I’ve been… (A Google+ post not archived in the WayBack machine)

It will kill explorer.exe, delete the IconCache.db, then starts explorer which will rebuild IconCache.db.

The Power of Open Source… Microsoft .NET and OpenShift: .Net on Linux

Posted by jpluimers on 2015/11/11

Really exiting times ahead: Microsoft .Net on Linux.

It’s not fully ready yet, but to get an idea to learn more about running OpenShift Enterprise 3 and a .NET application based on a Red Hat Enterprise Linux container, here are a few links to get started:

I wish that the demo repository at https://github.com/munchee13/snoopalicious.git and the rhosepaas.com domain were accessible (:

There are other alternatives too, but OpenShift (RedHat) and Microsoft working together is really exiting news to me.

If you’re on other distros, here are some more links:

And of course there has been Mono for a while, which is a different implementation of .NET:

Hopefully this will have search results soon: dnvm opensuse tumbleweed.

Hash Toolkit – Reverse MD5 / SHA1 Hashes

Posted by jpluimers on 2015/11/11

Interesting: Hash Toolkit – Reverse MD5 / SHA1 Hashes

They generate and allow you to generate various hashes, and store both the hash and original so you can reverse it.

Not meant for production data, but an approach for verifying if you do hashing correctly.

c# – TFS Code Reviews – Show updated files in response to comments – Stack Overflow

Posted by jpluimers on 2015/11/10

Nice steps here: c# – TFS Code Reviews – Show updated files in response to comments – Stack Overflow.

What’s missing here is that you now loose your history within the shelve-set.

That makes it harder for the reviewer to view the changes being re-reviewed.

Life in a post-database world: using crypto to avoid DB writes

Posted by jpluimers on 2015/11/05

Interesting: Life in a post-database world: using crypto to avoid DB writes.

For some security related operations, you only need smart use of HMAC, and no temporary database entries.

Thanks for the Jan Wildeboer referral to this.

Do not expose properties with writeable fields without a chance to react on the writes.

Posted by jpluimers on 2015/11/04

From a chat with a co-worker a while ago:

I’m not against properties. Just something against properties properties that are objects with writeable fields.

So even if you expose such a property as read-only, it can still get its writeable fields overwritten.

That is a pain when those are part of the state of the underlying object.

In other words: encapsulate your state changes.

Here we solved it by making

  • the type of the property immutable
  • the property writeable
  • react on state changes during the write

Proper encapsulation.

In this case it was a project mixing C# and Delphi, but you can easily apply the above to any language featuring classes and properties.

Another solution would have been to extend the type of the property so it can expose an event that fires during change. Much more convoluted.

c#: Lazy is not constrained to static contexts, instance field initialisers are – via: Stack Overflow

Posted by jpluimers on 2015/11/03

Lazy<T> is not constrained to static contexts.

Instance field initialisers cannot use instance references (but can use static references) as they run outside of the constructor.Though there are arguments for instance field initialisers too., I think this is a good reason to initialise fields inside the constructor: there you do have access to instance references (but should not call virtual instance methods or properties) which leads to another reason: consistency as field initialisers run in the opposite hierarchy order as constructors (incidentally causing this virtual method restriction).

Boy, that was a long sentence (:
