Network jobs watch: Hiring, skills and certification trends
22 April 2024 @ 5:39 pm
Network and infrastructure roles continue to shift as enterprises adopt technologies such as AI-driven network operations, multicloud networking, zero trust network access (ZTNA), and SD-WAN. Here’s a recap of some of the latest industry research, hiring statistics, and certification trends that impact today’s network professionals, infrastructure and operat
Altnets and neutral hosts: Are options widening for enterprise network services?
22 April 2024 @ 2:38 pm
Almost all enterprises get their network services from a big telco, but we’re starting to see a kind of network populism developing, generating things like “altnets” and “neutral hosts.” Might these new players offer things that could break the big-telco hold on enterprise services, and might they create both savings and headaches for enterprise? Yes, and yes.
An “altnet” is usually an independent retail broadband provider selling services in fringe areas – an alternative to one of the big telco or MSO providers. The idea is that an altnet focuses on a small geography, an area that has concentrated opportunity (what I call “demand density”) but is too limited to just
CSP Vultr launches sovereign cloud services
22 April 2024 @ 1:07 pm
GPU-based cloud services provider Vultr has launched a pair of new services designed to keep data within national borders to protect data sovereignty and maintain compliance.
“To address the growing need for countries to control their own data, and to reduce their reliance on a small number of large global tech companies, Vultr will now deploy sovereign clouds on demand for national governments around the world,” said J.J. Kardwell, CEO of Constant, Vultr’s parent company, in a statement.

Can your cloud backup provider fail?
19 April 2024 @ 3:46 pm
In the world of data protection, the cloud has emerged as a popular destination for backups. The appeal is obvious: Offload the complexities and costs of backup infrastructure to a provider, and rest easy knowing your data is safe in an off-site location. In addition, backing up to the cloud ensures that at least one copy of your backup data is stored off-site. Finally, many backup providers also offer immutable backups, which means that hackers can’t delete, encrypt, or corrupt your back
Cisco marries AI and security with cloud-based data center offering
18 April 2024 @ 5:22 pm
Cisco is tying together the intelligence of AI with the power of the cloud to deliver a system it says will proactively protect distributed applications, devices and data located across public and private data centers and clouds.
The new architecture, called Hypershield, is comprised of AI-based software, virtual machines, and other technology that will ultimately be baked into core networking components, such as switches, routers or servers. It promises to let organizations autonomously segment their networks when threats are a problem, gain rapid exploit protection without having to patch or revamp firewalls, and automatically upgrade software without interrupting computing resources,
Shredding files on Linux with the shred command
18 April 2024 @ 2:52 pm
The most obvious way to remove a file on a Linux system is to simply use the rm (remove) command. However, even though you will no longer see the file once it’s been deleted, this doesn’t mean that the file’s contents have been so thoroughly wiped from the disk that they can’t be recovered. Content will often sit on the disk until the space is used by a new file.
Another option – one that overwrites the file and optionally deletes it too – is called “shred”. As the name implies, the shred command will repeatedly change and rearrange the file’s data so that it can’t be recovered. It will also delete the file if you request that it do
Intel announces edge AI processors
18 April 2024 @ 2:01 pm
Intel and Altera, an Intel company, announced new edge-optimized processors that are specifically aimed at major vertical industries such as retail, manufacturing, healthcare, and aerospace. Unveiled at the Embedded World conference, the lineup consists of FPGA processors from Altera as well as Atom and Core CPUs and Arc discrete graphics.
One of the advantages of Intel’s edge AI processors is they are integrated into other Intel products and tied together with
HPE sues China’s Inspur Group for server patent infringement
18 April 2024 @ 10:52 am
Hewlett Packard Enterprise (HPE) has filed a lawsuit against Chinese tech conglomerate Inspur Group for infringing upon several of its server patents.
The case, lodged in the Northern District of California, also implicates several of Inspur’s subsidiaries, including Inspur Electronic Information Industry Company, Aivres Systems Inc., Betapex Inc., Inspur USA Inc., and KAYTUS Singapore Pte. Ltd. The complaint centers on allegations of widespread patent infringements that purportedly extend across multiple Inspur products.

The APAC sovereign cloud surge: How will it impact your business?
18 April 2024 @ 10:24 am
From Sydney to Seoul to New Delhi, a new type of cloud is casting a long shadow over technology strategies.
Sovereign clouds, designed to keep a nation’s data firmly within its borders, are upending traditional approaches to cloud computing for global enterprises operating in the Asia-Pacific (APAC).
Although it’s still in the early days, IDC’s survey shows that 19% of APEJ (Asia Pacific except Japan) organizations expect to increase their spending on sovereign cloud this year. According to Capgemini’s research, in Australia alone, 64% of organizations are actively investigating a sovereign cloud strategy, compared to 52% globally.

Intel builds world’s largest neuromorphic system
18 April 2024 @ 1:56 am
Quantum computing is billed as a transformative computer architecture that’s capable of tackling difficult optimization problems and making AI faster and more efficient. But quantum computers can’t be scaled yet to the point where they can outperform even classical computers, and a full ecosystem of platforms, programming languages and applications is even farther away.
Meanwhile, another new technology is poised to make a much more immediate difference: neuromorphic computing.
Neuromorphic computing looks to redesign how computer chips are
The problem has been that sometimes the node has crashed, so much that we can't even ssh into it.
And since the dns points to that node all applications stop being accessible.
So my though was to setup an external load balancer and point the dns to this.
Something like this:
I have tried using HAProxy with good results.
It seems to work fine.
But I am only using http between the load balancer and the k8s cluster.
I would like that 
Btrfs, which stands for "Butter FS" or "B-tree FS," is a modern Linux file system. It was developed to overcome the limitations of older file systems like ext4 or ext3. Btrfs is an excellent choice for efficient storage management on multiple Hard Disk Drivers. It supports Linux file systems with snapshots, subvolumes, and built-in RAID-like capabilities that provide robust data protection. It is designed to handle huge file systems and file sizes. Btrfs incorporates checksumming and COW (Copy-on-write), making it more resilient to data corruption. The COW feature means changes are written to new loc
{Updated} Are you getting, ' WARNING: UNPROTECTED PRIVATE KEY FILE!' when try to use the ssh command under Linux, macOS or BSD? Let us see how I fixed this problem and log in using the ssh command.The post SSH WARNING: UNPROTECTED PRIVATE KEY FILE! Error and Solution appeared first on nixCraft.
The Uncomplicated Firewall (UFW) needs to be configured to allow traffic on UDP ports 67 and 68, regardless of whether the Dynamic Host Configuration Protocol (DHCP) server is local or remote. Additionally, it may be necessary to open both TCP and UDP port 53, which are used for Domain Name Service (DNS). In small business and home environments, typically, both DNS and DHCP services come from a single device. Hence, it would be best if you opened both DHCP and DNS ports using the ufw comman
I recently had to submit multiple PDF files for government work, but the web form only allowed for the uploading of a single file. This meant that I had to merge the PDF files into one on Linux. To do this, I used a command-line tool called pdfunite, which is a Portable Document Format (PDF) page merger. Let us see how to install and use the pdfunite in Linux.

I am migrating an old Perl project from an unsupported OS to Fedora Linux 38. However, I discovered that Perl is not installed by default, while Python 3 is. This seems ridiculous. Anyway, here is how to install Perl in Fedora Linux including latest version of mod_perl with Apache (HTTPD) and get on with your life.
