Raising the temp on liquid cooling
23 February 2026 @ 10:00 am
Nvidia CEO Jensen Huang announced early this year that the new Vera Rubin processor, which is twice as powerful as the previous Grace Blackwell chip, doesn’t require its cooling water to be at a very cold temperature. In fact, the Vera Rubin can be cooled with water that’s 45 degrees Celsius, which is 113 degrees Fahrenheit. That’s hotter than the recommended settings for a hot tub. And it’s one degree hotter than the peak summer temperature in Las Vegas in 2025.

Arrcus targets AI inference bottleneck with policy-aware network fabric
20 February 2026 @ 2:41 pm
As AI usage continues to scale, there is a distinct type of application traffic that is having an impact on networking. Training isn’t the issue, it’s inference.
Training runs in centralized clusters on predictable schedules. Inference is distributed, latency-sensitive and subject to real-time constraints around power availability, data sovereignty, and cost. The network fabric that is routing that traffic is increasingly the bottleneck, and traditional hardware-defined networking was not built to handle it.
That is the problem Arrcus is moving to address. The San Jose-based networking software company has spent a decade building ArcOS, a network operating system designed

Bluetooth is limited to short range. None of those technologies were designed with massive-scale, low-power IoT as the pri
Data stored in glass could last over 10,000 years, Microsoft says
19 February 2026 @ 12:36 pm
Enterprises struggling with the cost and complexity of long-term data archival could soon have a new option: a piece of glass.
New research published on Wednesday suggests that a borosilicate glass plate 120mm square and just 2mm thick can store 4.8TB of data across 301 layers with accelerated aging tests, indicating that the data would remain intact for at least 10,000 years.

How to install KSH on FreeBSD
3 March 2025 @ 11:50 pm
Installing KSH (KornShell) on FreeBSD can be done with either FreeBSD ports or the pkg command. The ports collection will download the KSH source code, compile it, and install it on the system. The pkg method is easier, and it will download a pre-compiled binary package. Hence, it is recommended for all users. KornShell (KSH) has a long history, and many older Unix systems and scripts rely on it. As a result, KSH remains relevant for maintaining and supporting legacy infrastructure. Large enterprises, especially those with established Unix-based systems, continue to use KSH for scripting and system administration tasks.

3 March 2025 @ 9:47 am
Sed is an acronym for "stream editor." A stream refers to a source or destination for bytes. In other words, sed can read its input from standard input (stdin), apply the specified edits to the stream, and automatically output the results to standard output (stdout). Sed syntax allows an input file to be specified on the command line. However, the syntax does not directly support output file specification; this can be achieved through output redirection or editing files in place while making a backup of the original copy optionally. Sed is one of the most powerful tools on Linux and Unix-like systems. Learning it is worthwhile, so in tHow to tell if FreeBSD needs a Reboot using kernel version check

15 January 2025 @ 6:04 pm
Rsync is a opensource command-line tool in Linux, macOS, *BSD and Unix-like systems that synchronizes files and directories. It is a popular tool for sending or receiving files, making backups, or setting up mirrors. It minimizes data copied by transferring only the changed parts of files, making it faster and more bandwidth-efficient than traditional copying methods provided by tools like sftp or ftp-ssl. Rsync versions 3.3.0 and below has been found with SIX serious vulnerabilities. Attackers could exploit these to leak your data, corrupt your files, or even take over your system. There is a heap-based buffer overflow with a CVSS score of 9.8 that needs to be addressed on both the client and server sides of rsync package. Apart from that info leak via uninitialized stack contents defeats ASLR protection and rsync server can make client write files outside of destination directory using symbolic links.

How to control the SSH multiplexing with the control commands
15 January 2025 @ 8:29 am
Multiplexing will boost your SSH connectivity or speed by reusing existing TCP connections to a remote host. This is useful when you frequently connect to the same server using SSH protocol for remote login, server management, using IT automation tools over SSH or even running hourly backups. However, sometimes your SSH command (client) will not respond or get hung up on the session when using multiplexing. Typically, this happens when your public IP changes (IPv4 to IPv6 changes when using DNS names), VPN issues, or firewall cuts connections. Hence, knowing SSH client control commands can save you time and boost your productivity when such gotcZFS Raidz Expansion Finally, Here in version 2.3.0
14 January 2025 @ 9:19 am
After years of development and testing, the ZFS raidz expansion is finally here and has been released as part of version 2.3.0. ZFS is a popular file system for Linux and FreeBSD. RAIDz is like RAID 5, which you find with hardware or Linux software raid devices. It protects your data by spreading it across multiple hard disks along with parity information. A raidz device can have single, double, or triple parity to sustain one, two, or three hard disk failures, respectively, without losing any data. Hence, expanding or adding a new HDD is a very handy feature for sysadmins in today's data-sensitive apps.

How to run Docker inside Incus containers
18 December 2024 @ 5:44 am
Incus and Docker both use Linux kernel features to containerize your applications. Incus is best suited when you need system-level containers that act like traditional VMs and provide a persistent developer experience. On the other hand, Docker containers are ephemeral, i.e., temporary in nature. All files created inside Docker containers are lost when your Docker container is stopped or removed unless you stored them using volumes in different directories outside Docker. Docker is created as a disposable app deployment system. Incus containers are not typically created as disposables, and data is kept inside heartinternet.co.uk

Building a Custom Read-Only iSCSI Target on Windows (Physical Disk Export)
23 February 2026 @ 12:01 pm
I want to implement a custom iSCSI target on Windows Server 2019 that exports a physical disk (\.\PhysicalDriveX) in strict read-only mode to a Windows client.
Requirements:
Disk should appear as a locally attached SCSI disk on the client.
Full disk layout visible (GPT/MBR, partitions).
All WRITE commands rejected.
No VHD/VHDX wrapper.
Questions:
Is user-mode implementation (Winsock + raw disk reads) sufficient, or is a kernel-mode StorPort/virtual SCSI driver required?
Which Windows components or tools are needed (Windows SDK, WDK)?
If implemented as read-only at SCSI level, is it architecturally safe from disk corruption?
Looking for architectural guidance on the correct implementation path.

ubuntu 24.04 running redmine, apache2.4 asks for multiple logins
21 February 2026 @ 4:10 pm
Running redmine under apache 2.4 on ubuntu 24.04.
The apache server is set up to require logins.
Under normal circumstances, one logs in to the apache server once, then when one requests a redmine page one logs into redmine once. Subsequently, additional tabs require no logins on either apache or redmine.
However, under some conditions which I have not been able to pinpoint, when one switches browser tabs or tries to update an issue, the apache server asks for another login; redmine seems to maintain state ok and does not request additional logins. When this happens the login request seems like it is in some kind of loop, as it comes up multiple times. It's not clear whether it is asking for logins for tabs other than the one currently being viewed and is getting confused, or if it is just in a loop. In order to get out of this condition I have had to completely exit the browser. It happens with both firefox and chrome.
Does anyone have any idea wh
Linux hangs on IO operations [migrated]
21 February 2026 @ 2:43 pm
Since several days now, my Linux desktop (Fedora Linux 43 Workstation) has occasional IO "hangs". So far I noticed
Playing MP3s from an NFS filemount
Writing to the local filesystem (e.g. when saving a file in a texteditor)
Reading from the local filesystem
When it happens, the thread with the operation is freezing 2-20 seconds and then continues normally.
I don't see any messages journalctl or dmesg.
I suspect that it started with the last batch of installed package updates, but I have no clue how to approach this without a hint in the logs.
Current kernel is 6.18.8-200.fc43.x86_64, built on 30. January (not by me).
Do you have any other advice how to triage this?
Ubuntu Server 22.04 – Wi‑Fi PCIe card detected but no IP with Netplan (NO‑CARRIER, state DOWN) [migrated]
21 February 2026 @ 12:53 pm
I bought a WiFi card on Amazon for an Ubuntu Server. I know it's not optimal for a server, but I don't need it running 24/7—it's for personal use and I can't run a cable.
I installed the card, and when I run ip a, I can see the new WiFi interface:
3: wlp2s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
link/ether e0:e2:58:aa:13:51 brd ff:ff:ff:ff:ff:ff
I modified my /etc/netplan/01-netcfg.yaml config file to manage this new interface. But when I run sudo netplan generate followed by sudo netplan apply, I still don't get an IP address when I check ip a.

Domain Controller Change Region settings
21 February 2026 @ 8:41 am
I need to change the timestamp format of the logs in C:\Windows\System32\dns\dns.log to include the complete year in the logs timestamp. Since the time stamp format in this log file is based on Region settings, I would have to change the format there and then use the "Administrative" tab in the "Region" settings to Copy settings to the system account. I believe this not only changes the format in dns.log but also systemwide. Since this is a production Domain controller, I would like to know what adverse effects this could have. Will it affect the current functionality of the domain controller? If this not recommended what other alternative method is possible to just change the format only in the dns.log?
