Red Hat Will Revert Spectre Patches After Receiving Reports of Boot Issues
Red Hat is releasing updates that are reverting previous patches for the Spectre vulnerability (Variant 2, aka CVE-2017-5715) after customers complained that some systems were failing to boot.
"Red Hat is no longer providing microcode to address Spectre, variant 2, due to instabilities introduced that are causing customer systems to not boot," the company said yesterday.
"The latest microcode_ctl and linux-firmware packages are reverting these unstable microprocessor firmware changes to versions that were known to be stable and well tested, released prior to the Spectre/Meltdown embargo lift date on Jan 3rd," Red Had added.

The impromptu Slack war room where ‘Net companies unite to fight Spectre-Meltdown | Ars Technica
When major security vulns go live without warning, competitors suddenly band together.
Meltdown and Spectre created something of a meltdown in the cloud computing world. And by translation, the flaws found in the processors at the heart of much of the world's computing infrastructure have had a direct or indirect effect on the interconnected services driving today's Internet. That is especially true for one variant of the Spectre vulnerability revealed abruptly by Google on January 3, since this particular vulnerability could allow malware running in one user's virtual machine or other "sandboxed" environment to read data from another—or, from the host server itself.
In June 2017, Intel learned of these threats from researchers who kept the information under wraps so hardware and operating system vendors could furiously work on fixes. But while places like Amazon, Google, and Microsoft were clued in early because of their "Tier 1" nature, most smaller infrastructure companies and data center operators were left in the dark until the news broke on January 3. This sent many organizations immediately scrambling: no warning of the exploits came before proof-of-concept code for exploiting them was already public.

Meltdown and Spectre: Good news for AMD users, (more) bad news for Intel | Ars Technica
Windows patches are fixed, but microcode updates are causing even more trouble.
The good news: Microsoft suspended shipping its Spectre and Meltdown Windows patches to owners of AMD systems after some users found that they left their systems unbootable. Microsoft partially lifted the restriction last week, sending the update to newer AMD systems but still leaving the oldest machines unpatched.
Now the company has an update that works on those systems, too. If you're unfortunate enough to have installed the previous, bad update and now have a system that crashes on startup, you'll still have to roll back the bad update before you can install the new one. We've read reports that this is indeed possible, but unfortunately, Microsoft only offers generic guidance on troubleshooting blue screen of death crashes, not any specific steps to fix this specific issue.

Microsoft Resumes Meltdown & Spectre Updates for AMD Devices
Microsoft has resumed the rollout of security updates for AMD devices. The updates patch the Meltdown and Spectre vulnerabilities.
Microsoft released these patches on January 3, but the company stopped the rollout for AMD-based computers on January 9 after users reported crashes that plunged PCs into unbootable states.
After working on smoothing out the problems with AMD, Microsoft announced today it would resume the rollout of five (out of nine) security updates. The five updates are:

Commodore C64 Book: Inside the Commodore 64 (1983)(French Silk)

There are basically two parts to this book. The first part deals with the 6502 and 6510 microprocessors. A complete description is provided of these machines and how they function and how they are programmed ... The second section covers the Commodore 64 specifically. It elucidates the graphics capabilities, the music synthesiser and the internal programs which are burned into the ROMSs of the 64. Examples of machine language proramming techniques are provided to illustrate the programmer's means of accessing ths capabilities. Throughout the book, the assembly language conventions used are those of Develop-64 ...-Introduction
