Linux Systemd & Golang Services using Kardianos Service

This week I have done something new, but I found myself dealing with a ‘zero knowledge’ situation or something I like to call ZKS. This is one of those ones where it’s fun, but it also feels a bit stressy as there was enough rope to hang myself with.

That something new is Systemd, which is a Linux operating system thing that manages the initialisation of user things. To speak about this more technically, it is a drop in replacement ‘init’ system that starts services and sets up the user environment. Wikipedia has this to say about it:

Systemd is an init system used in Linux distributions to bootstrap the user space and manage all processes

For those lacking historic knowledge around systemd, it previously many upset devs and administrators, which in turn setup a site called ‘boycottsystemd’ which looks to be offline. They said it flies in the face of doing it the Unix way, which is (to summarise) do one thing and do it well. Systemd is now the default init system for Ubuntu 15x and newer releases. Can’t be that bad…right?

Whilst this is not a complete education around systemd, it’s popular and is reasonably easy to Continue reading

IDG Contributor Network: 4 ways to contain IT storage creep

In most businesses, data grows rapidly, voraciously consuming storage as it does so and ratcheting up expenses. Sometimes it seems impossible to keep it under control.However, there is a difference between the Blob and storage that puts you in the driver’s seat. Data didn’t arrive on earth courtesy of a meteorite. We create it by ourselves every day. If we produced the problem, we should be able to defend against it and its associated costs. Here are some ways you can improve storage efficiency.1. Tier your data Wouldn’t it be nice if business unit leaders would come to you and say, “I need a sub-millisecond response time on my reads and writes for this application,” plus inform you of all their other requirements? That would make it easy to determine the IT resources you should assign to an application. The truth, however, is that in many cases, business leaders don’t know what they need. They just want to make sure that the application does not slow down operations in their department.To read this article in full or to leave a comment, please click here

Desktop Linux the best it’s ever been—and keeps getting better

I can be a pretty pessimistic guy. I’m fairly convinced that the Internet of Things spells certain doom for mankind, and I’ve made a habit of standing in front of large rooms full of people simply to tell them how much I think “Linux sucks.” If you were to call me a Negative Nancy, you wouldn’t be far off.To make matters worse, I’m about to publish three new articles—each of them extremely pessimistic and gloomy—over the next week. otal “sky is falling, we’re all gonna die” sort of stuff.To read this article in full or to leave a comment, please click here

ARM Antes Up For An HPC Software Stack

The HPC community is trying to solve the critical compute challenges of next generation high performance computing and ARM considers itself well-positioned to act as a catalyst in this regard. Applications like machine learning and scientific computing are driving demands for orders of magnitude improvements in capacity, capability and efficiency to achieve exascale computing for next generation deployments.

ARM has been taking a co-design approach with the ecosystem from silicon to system design to application development to provide innovative solutions that address this challenge. The recent Allinea acquisition is one example of ARM’s commitment to HPC, but ARM has worked …

Introducing Zero Round Trip Time Resumption (0-RTT)

Cloudflare’s mission is to help build a faster and more secure Internet. Over the last several years, the Internet Engineering Task Force (IETF) has been working on a new version of TLS, the protocol that powers the secure web. Last September, Cloudflare was the first service provider to enable people to use this new version of the protocol, TLS 1.3, improving security and performance for millions of customers.

Today we are introducing another performance-enhancing feature: zero round trip time resumption, abbreviated as 0-RTT. About 60% of the connections we see are from people who are visiting a site for the first time or revisiting after an extended period of time. TLS 1.3 speeds up these connections significantly. The remaining 40% of connections are from visitors who have recently visited a site and are resuming a previous connection. For these resumed connections, standard TLS 1.3 is safer but no faster than any previous version of TLS. 0-RTT changes this. It dramatically speeds up resumed connections, leading to a faster and smoother web experience for web sites that you visit regularly. This speed boost is especially noticeable on mobile networks.

We’re happy to announce that 0-RTT is Continue reading

Malicious uploads allowed hijacking of WhatsApp and Telegram accounts

A vulnerability patched in the web-based versions of encrypted communications services WhatsApp and Telegram would have allowed attackers to take over accounts by sending users malicious files masquerading as images or videos.The vulnerability was discovered last week by researchers from Check Point Software Technologies and was patched by the WhatsApp and Telegram developers after the company privately shared the flaw's details with them.The web-based versions of WhatsApp and Telegram synchronize automatically with the apps installed on users' phones. At least in the case of WhatsApp, once paired using a QR code, the phone needs to have an active internet connection for WhatsApp messages to be relayed to the browser on the computer.To read this article in full or to leave a comment, please click here

Twitter accounts hacked, Twitter Counter steps forward as culprit

Twitter Counter, a third-party analytics service, appears once again to have provided a gateway for hackers to post messages to high-profile Twitter accounts.An unlikely number of Twitter users suddenly learned to speak Turkish on Wednesday, posting an inflammatory message in the language replete with Nazi swastikas.Among those posting the message were the Twitter accounts of Forbes magazine, the Atlanta Police Department, and Amnesty International, one of the few hacked accounts one might expect to speak Turkish.Fears that these accounts had all been hacked were quickly allayed, when Twitter identified a third-party app as being to blame.To read this article in full or to leave a comment, please click here

Review: MongoDB learns cool new tricks

MongoDB 3.4 continues the trend of databases building out support for a range of conceptual data models over the same underlying data store. This multimodel approach aims to deliver a single database that can be used to store data as documents, tables, and graphs simultaneously. The benefit to the user is a dramatically simplified infrastructure when compared to a polyglot persistence model, which might entail managing three or four separate data stores to satisfy those different use cases.To read this article in full or to leave a comment, please click here(Insider Story)

Spy agency, DOE, see China nearing supercomputing leadership

Advanced computing experts at the National Security Agency and the Department of Energy are warning that China is "extremely likely" to take leadership in supercomputing as early as 2020, unless the U.S. acts quickly to increase spending.China's supercomputing advances are not only putting national security at risk, but also U.S. leadership in high-tech manufacturing. If China succeeds, it may "undermine profitable parts of the U.S. economy," according to a report titled U.S. Leadership in High Performance Computing by HPC technical experts at the NSA, the DOE, the National Science Foundation and other agencies.To read this article in full or to leave a comment, please click here
