Like any good sysadmin, I kept my servers and desktop side up to date and patched all the time. However, recent Java updates have broken my IPMI KVM Java Applets on Dell, IBM, HP, Supermicro and FreeNAS mini servers. You will get an error that read as follows:
Unsigned application requesting unrestricted access to system. The following resource is signed with a weak signature algorithm MD5withRSA and is treated as unsigned.
Intel announced Euclid development kit for robotics. It is Ubuntu Linux 16.04 based system. One can run, monitor and manage their robotics apps with the web interface. The software works with any ROS-based (Robotics Operating System) robot such as Arduino to build sensing capabilities in your project. You can use sensors and cameras to control a robot.
GnuBee is a personal NAS (Network Attached Storage) cloud server that is currently being funded on Crowd Supply. It is a low-cost, low-power, NAS device that runs GNU/Linux and it is claimed to be based on free, libre, and open source software. No proprietary drivers needed to use GnuBee.
Everyone loves the desktop operating system. People customize their Linux or Unix desktop with themes, wallpapers, killer configuration and more. These customizations show you how cool your desktop can be!
I recently installed TomatoUSB advanced firmware on my Asus RT-AC66U wifi router. This router act as my wireless Ethernet bridge. TomatoUSB advanced has additional features like
- Multiple WAN support (3G/4G/Static IP/Cable/ADSL2)
- Virtual Wireless
- FTP/Media server via USB
- BiTorrent Client via USB
- UPS support
- OpenVPN client and server
- Tinc VPN server and much more.
Coreboot is a free and open source software. The project aimed at replacing the proprietary BIOS firmware and blobs. Unfortunately, Coreboot does not run on the modern laptop (except Chromebooks) due to Intel ME and other closed source technologies.
Purism vendor sells Linux preloaded on the Librem 13 and the Librem 15 laptops. Purism claims to follow a strict belief in users’ rights to privacy, security, and freedom. Untile today Librem bios was not freed. However, the coreboot port for the Librem 13 v1 is 100% done. It means you can have blob free Coreboot running on a full-fledged modern laptop. The laptop comes with Hardware Kill Switches that physically sever the circuit at the hardware level for Wireless & Bluetooth, Camera & Microphone. The specs are as follows:
Oops! I did it again. I thought I was logged into my home server. Turns out I rebooted the db server. Another my not so favorite is typing “shutdown -h 0” into the wrong terminal. I know a few people who have admitted to doing that here.
Is there any end to the madness? Do I need to suffer from accidentally random reboots and shutdowns? After all, it is human nature to make mistakes, but one should not keep on making the same mistakes again and again.
Intel’s Atom C2000 chips are bricking products, and it’s not just Cisco hit. From the theregister:
Intel’s Atom C2000 processor family has a fault that effectively bricks devices, costing the company a significant amount of money to correct. But the semiconductor giant won’t disclose precisely how many chips are affected nor which products are at risk. Coincidentally, Cisco last week issued an advisory warning that several of its routing, optical networking, security and switch products sold prior to November 16, 2016 contain a faulty clock component that is likely to fail at an accelerated rate after 18 months of operation.
Intel has “Silvermont” which is a microarchitecture for low-power Atom, Celeron and Pentium branded processors used in systems on a chip (SoCs) made by Intel. It includes:
- Avoton – SoCs for micro-servers and storage devices.
- Rangeley – SoCs targeting network and communication infrastructure.
Recently I came across an excellent software called CoreFreq. It is a CPU monitoring software designed for 64-bits Processors w/ architectures Intel Atom, Core2, Nehalem, SandyBridge and superior, and AMD Family 0F. It runs on 64 bit Linux system. CoreFreq provides a framework to retrieve CPU data with a high degree of precision:
Raptor Engineering is working and crowdfunding a high-end power8 based desktop computer with zero proprietary firmware blobs in the Talos Secure Workstation. Traditionally IBM, Oracle(Sun), Intel/AMD and others ruled this market segment. But now there is competition to Intel for a desktop computer.
