Windows Flaw Reveals Microsoft Account Passwords, VPN Credentials

Posted by jpluimers on 2016/08/08

Attack from the ’90s resurfaces more deadly than before

Source: Windows Flaw Reveals Microsoft Account Passwords, VPN Credentials

TL;DR: block LAN->WAN port 445

Note this won’t affect web-dav shares like \live.sysinternals.com\DavWWWRoot as that uses ports 443 and 80.

OpenSuSE Tumbleweed `zypper dist-upgrade`: `mt-st` versus `mt_st`

Posted by jpluimers on 2016/08/08

TL;DR: I’m not the only one being partially word-blind.

I had the below while performing a zypper distribution upgrade on "openSUSE Tumbleweed (20160726) (x86_64)".

revue:/etc # zypper dist-upgrade
...
Detected 2 file conflicts:

File /usr/bin/mt
  from install of
     mt-st-1.3-1.1.x86_64 (Main Repository (OSS))
  conflicts with file from package
     mt_st-1.3-1.2.x86_64 (@System)

File /usr/sbin/stinit
  from install of
     mt-st-1.3-1.1.x86_64 (Main Repository (OSS))
  conflicts with file from package
     mt_st-1.3-1.2.x86_64 (@System)

File conflicts happen when two packages attempt to install files with the same name but different contents. If you continue, conflicting files will be replaced losing the previous content.
Continue? [yes/no] (no): no

Problem occured during or after installation or removal of packages:
Installation aborted by user

Please see the above error message for a hint.

Did you see the cause of the error in the above message?

Neither did I.

So I went to the #opensuse-factory IRC channel on freenode with this information:

There cooloo pointed out both the cause and solution were deceptively simple:

coolo: wiert: zypper remove mt_st ; zypper dup; zypper in mt-st
coolo: the package was incorrectly renamed

My partial word-blindness didn’t spot the difference between mt_st and mt-st, but it was indeed renamed.

So here I went:

zypper remove mt_st ; zypper dist-upgrade; zypper install mt-st

Note that strictly zypper install mt-st isn’t needed on my system as it is part of  Base:System. which means that zypper dist-upgrade automatically re-installed it.

Graphical emoji are killing Unicode

Posted by jpluimers on 2016/08/05

Unicode is about Glyphs that are used in writing. Have you ever seen the emoji on the right being written like this?

This has been bothering me a while and gets worse over time.

According to: Microsoft just changed its toy gun emoji to a real pistol:

Looks like Microsoft and Apple may not be on the same page about firearm emojis afterall. Right after Apple changed its gun emoji to a water pistol in iOS 10, Microsoft replaced its toy pistol emoji with an actual revolver.

…

While Apple and Microsoft have gone back to edit their symbols, Google continues to use a pistol in Android keyboards and doesn’t appear to have plans to change this. None of the companies in question have adjusted their knife, sword, bomb, poison and coffin emojis, so… ¯\_(ツ)_/¯

When vendors start prescribing how emojis must look like (influenced by all sorts of emotions) without the user allowing to choose (via a font – that’s what fonts are for!) how they look then it invalidates the whole Unicode principle:

Unicode is a computing industry standard for the consistent encoding, representation, and handling of text expressed in most of the world’s writing systems.

These emoji aren’t text and should be gone from the Unicode standard before they can do more harm.

Will the next step be that vendors define their own colours for certain characters in fonts? For Windows Times New Roman A becomes red, B green, C yellow, but in Courier New we’ll permute these colours and all Operating Systems and Versions will do different random colour choices.

When you get a black screen with mouse cursor: Fast Startup – Turn On or Off in Windows 10 – Windows 10 Forums

Posted by jpluimers on 2016/08/05

The Windows 10 installation does not warn you about it but the Fast Startup in Windows 10 will fail with many video cards and display drivers. This happens a lot on older hardware which somehow Microsoft thinks deserves to be auto-upgraded to Windows 10.

Usually you will see this when – after a previous shutdown – you boot and you get a black screen with a mouse cursor.

If you wait long enough, the machine will go to sleep and if you un-sleep it by pressing the spacebar most of the times everything will be fine.

The actual solution that works most of the time is to disable Fast Startup as described in Fast Startup – Turn On or Off in Windows 10 – Windows 10 Forums.

Sometimes there are other solutions which you can see in the below video.

bash – How can I convert tabs to spaces in every file of a directory? – Stack Overflow

Posted by jpluimers on 2016/08/05

Kev:

Try the command line tool expand.

expand -t 4 input >output

Chrono Kitsune:

And for those systems that don’t use the GNU Core Utilities, you have a decent chance of expand being installed since it is standardized by The Open Group’s Single Unix Specification. See Issue 6, which is from 2001, though some updates were applied, hence the year of publication being 2004: expand

Frequent password changes are the enemy of security, FTC technologist says – via Kristian Köhntopp – Google+

Posted by jpluimers on 2016/08/03

Frequent password changes are the enemy of security, FTC technologist says

Source: Kristian Köhntopp – Google+

Since the 1980s I’ve been advocating the above opinion and I’m glad some people now agree with me.

If you ever hire or employ me and force such a regular password change policy upon me without allowing me to use a password manager that can communicate securely with the cloud (which means you don’t play TLS man-in-the-middle) then I will either:

  • create a password-change script that invalidates the password history you keep and re-use my really secure password of choice.
  • if that fails: add an incrementing value to a reasonably secure base password.

Insentricity :: This Letter Quality Printer Is Now Fully Armed and Operational ::

Posted by jpluimers on 2016/08/03

Chris Osborn was finally able to open up his 1980s Smith Corona Memory Correct 400 Messenger and replace the fuse, enabling him to do letter quality printing over over the parallel port (and hopefully the serial port soon too).

Cool!
