DebugPoint Weekly Roundup #22.08: Ubuntu Pro, System76's Iced Toolkit Debate and More

Programming Leftovers



Hackers Exploiting Unpatched RCE Flaw in Zimbra Collaboration Suite


↺ Hackers Exploiting Unpatched RCE Flaw in Zimbra Collaboration Suite


> A severe remote code execution vulnerability in Zimbra's enterprise collaboration software and email platform is being actively exploited, with no patch currently available to remediate the issue.


> [...]


> Zimbra said it expects the vulnerability to be addressed in the next Zimbra patch, which will remove the dependency on cpio and instead make pax a requirement. However, it has not offered a specific timeframe by when the fix will be available.



Windows High Contrast Improvements


↺ Windows High Contrast Improvements


> Spent a little time this week to explore our Windows accessibility High Contrast support because I was working on a GTK High Contrast issue by coincidence when xisco mentioned the Windows one in the regular ESC.



First Beta Release of PowerDNS Recursor 4.8.0 | PowerDNS Blog


↺ First Beta Release of PowerDNS Recursor 4.8.0 | PowerDNS Blog


> We are proud to announce the first beta release of PowerDNS Recursor 4.8.0.



First release candidate for Authoritative Server 4.7.0 | PowerDNS Blog


↺ First release candidate for Authoritative Server 4.7.0 | PowerDNS Blog


> This is the first release candidate for Authoritative Server 4.7.0. We hope it will also be the last


> 4.7.0 brings support for Catalog Zones, developed by Kees Monshouwer. As part of that development, the freshness checks in the Primary code were reworked, reducing them from doing potentially thousands of SQL queries (if you have thousands of domains) to only a few. Installations with lots of domains will benefit greatly from this, even without using catalog zones.


> 4.7.0 also brings back GSS-TSIG support, previously removed for quality reasons, now reworked with many stability improvements.



I've been playing with OS/2 again -- more on that soon -- but it was doomed from a young age


↺ I've been playing with OS/2 again -- more on that soon -- but it was doomed from a young age


> OS/2 2.0 came out in April 1992. Windows 3.0 came out in May 1990, 2 whole years earlier. It already had established an ecosystem before 32-bit OS/2 appeared.


> Secondly, OS/2 2 really wanted a 386DX and 4MB of RAM, and a quality PC with quality name-brand parts. I owned it. I ran it on clones. I had to buy a driver for my mouse. From another CONTINENT.


> Windows 3.0 ran on any old random junk PC, even on a PC XT class box with EGA. At first only high-end users of high-end executive-class workstations got the fun of 386 Enhanced Mode, but that was all OS/2 2.0 could run on at all.


> OS/2 died when OS/2 1.x was a high-end OS with low-end features, and a cheapo low-end 386SX PC with 1 or 2MB of RAM, with MS-DOS and DESQview (not DESQview/X, just plain old text-mode DESQview) could outperform it.


> (Remember the 386SX came out in 1988 and was common by the time Windows 3.0 shipped.)


> But as soon as OS/2 1.x was a flop, MS turned its attention back to Windows, and before even the first betas of Windows 3.0, there were rumours in the tech press that MS was going to abandon the project. This was widely discussed in the media at the time. In my then-job, around 1989, my boss sent me on a training course for 3Com's new NOS, 3+Open, which was based on OS/2 1.0.
