5 best code editors for Linux users

Date Published: Sun, 31 Mar 2019 13:50:29 +0200

Linux is a go-to OS for many developers. Because so many people use Linux for development, the platform is littered with dozens of development tools, both good and bad. If you’re sick of wading through programs to find a good code editor for your Linux development PC this list may help.

Yes, you may be surprised to see Microsoft and Adobe in this list but the editors are both open source code. Personally, I actually use Visual Studio for Python.

Linux laptops alive in South Africa - By Dell at Least

Date Published: Sun, 31 Mar 2019 13:44:04 +0200

Dell and Canonical recently announced the new version of the Dell XPS 13 Developer Edition laptop, offering up to 16GB RAM and a 1TB SSB. Since then, a 2TB version has become available. Like other Developer Edition variants of the Dell XPS 13, the 2018 model comes with Ubuntu Linux rather than Windows. At the time, the latest long-term support release: Ubuntu 18.04 “Bionic Beaver”.

Despite the fact that these laptops serve a small demand, Dell continues to offer them in South Africa. “You can order today,” he said. Buchanan said that many computer users still consider Linux as a technical operating system, however, and perhaps don’t understand it.

Linux performs a range of tasks better than Windows, though, including the package management features it offers.

So if you are a Linux user in South Africa choose Dell and don't pay for an OS you won't be using.

Single Blade Razors With A Pivot?

Date Published: Sat, 30 Mar 2019 15:47:52 +0200

After years of single blade razors with a rigid head, and multi-blade razors with pivots, there is now an upstart group of razors that have a single blade and a pivot. Could it be the best of both worlds?

If there is one thing that transitioning to shaving with a double edge (DE) razor ten years ago did for me, it is to show me that I don’t need a multi-blade cartridge that vibrates like a marital aid to get a great shave. A single blade gives me great results, and a lot more cheaply thankyouverymuch.

But one thing I do think that “modern” razor engineering got right is the concept of using a pivot in the razor head. I think a razor with a pivoted head provides a more consistent shave with less effort compared to a razor with a non-moving head.

And it appears I am not alone with that view. Several razors with a single blade on a pivoted head are now available.

Four existing ones are reviewed and an emerging one is covered at…

The Complete Guide for Using ffmpeg in Linux - Literally the "Swiss Army Life" of media file manipulation in Linux

Date Published: Sat, 30 Mar 2019 12:26:29 +0200

ffmpeg is a CLI (command line based) utility for processing media files. It is a framework with a multitude of features and, because of it’s open sourcee license, it is the base for many widespread apps such as VLC, YouTube, iTunes and many more. A number of Linux video editors use ffmpeg underneath the GUI.

So even though you may not ever have used ffmpeg from the command line yourself many (most) application do so in the background without you ever seeing it. The guide below not only shows how to install it but also lists the myriad of ways you can use it to manipulate media files yourself (or as a programmer how you could use it from your application).

A surprising number of people trust AI to make better policy decisions than politicians

Date Published: Sat, 30 Mar 2019 11:53:51 +0200

A new survey on Europeans’ attitudes towards technology found that a quarter of people would prefer it if policy decisions were made by artificial intelligence instead of politicians.

The Center for the Governance of Change at Spain’s IE University polled 2,500 adults in the UK, Spain, Germany, France, Ireland, Italy, and the Netherlands in January. The results reflect an intense anxiety about the changes brought about by advances in tech, with more than half of respondents worried that jobs would be replaced by robots, and 70% saying that unchecked technological innovation could do more harm than good to society. Respondents also expressed concerns about the impact of digital relationships replacing human contact as more people spend time online.

Perhaps most interestingly, a quarter of the respondents said they would prefer AI to guide decisions about governance of their country over politicians.

“This mindset, which probably relates to the growing mistrust citizens feel towards governments and politicians, constitutes a significant questioning of the European model of representative democracy, since it challenges the very notion of popular sovereignty,” Diego Rubio, the executive director for IE’s Center for the Governance of Change, said in a statement.

Around the world, citizens have expressed a growing disillusionment with democracy, and an increased skepticism that their voice has an impact on political decisions.

Very interesting so it's not just call centre agents who may have to fear losing their jobs to AI. It should be a wake-up call though to politicians to get in touch with the humanity of the people they serve and make to make a difference. Let's just hope politicians tackle this positively and don't retreat into just resisting AI. They need to see it as a competitive challenge to do better.

Sony launches Wena smartwatch strap internationally - it adds subtle "smart" to existing classic mechanical watches

Date Published: Sat, 30 Mar 2019 11:30:16 +0200

The Wena watch strap upgrades any traditional watch with fitness tracking, contactless payments and phone notifications. All of the technology has been carefully designed to fit within the gentle curve of the watch clasp, including a small OLED screen where notifications are displayed. So it is not "vibrate only" alerts but even has a small OLED display.

Two strap designs are available: the Wena Wrist Pro, a classic metal link style in either silver or black, or the Wena Wrist Active, which has a silicone strap made for fitness.

The Active model comes with additional GPS and heart tracking. It also has a "quick-release system" that allows the watch face to be easily removed during exercise, making the accessory lighter and giving it the appearance of a Fitbit-style fitness tracker.

Both band styles are 20 millimetres wide and attach to any watch that takes an 18-, 20- or 22-millimetre lug, although Sony also offers the option of five of its own watch face designs.

Sony has sold the watch strap in Japan since 2015, but is now launching the product internationally.

There are also two solar-powered models and two entry-level quartz models, each available in Three Hands and Chronograph styles.

I seriously believe, due to the versatility of this working with most other mechanical watches, that this is hitting a real sweet spot for lovers of classic mechanical watches. It has a display but it is very discreet and you are getting all the typical notifications that smartwatches get. Only thing really not there are the smartwatch apps like grocery shopping list apps.

Battery life for the strap is about 1 week which is acceptable. The bigger issue for me (lesson learnt from the LG WAtch Sport) is everything is built into the strap, and the strap is usually what wears so how long is the strap expected to last?

Largest cannabis expo on African continent in Cape Town next weekend - Certainly a new opportunity opening up in the economy

Date Published: Fri, 29 Mar 2019 20:05:28 +0200

It has been less than a year since using cannabis at home was made legal in South Africa, and now the city will host the largest cannabis expo on the continent at the GrandWest Arena next week. The expo will host more than 100 exhibitors showcasing a variety of cannabis-related products and services from all sectors in the industry including health care, medicinal, growing, harvesting and processing technologies, product retailers and innovators, legislation groups and government departments.

“The Cannabis Expo is not just about the recreational, it is not about promoting the notion of getting high, but rather has a focus on having a central, controlled place where experts in the industry impart valuable knowledge, make available cannabis-related products and educate and inform South Africa and the world about this vast industry.

Omron HeartGuide - The First Smartwatch to Read Your Blood Pressure Is an Ugly Marvel

Date Published: Fri, 29 Mar 2019 19:49:29 +0200

There’s a reason they call high blood pressure the silent killer. The Center for Disease Control says 75 million Americans suffer from hypertension, a sobering one in three adults. Worse, it says only 54 percent have their condition under control—a fact made more awful by the fact that hypertension is a contributing cause for about 1,100 deaths per day.

The way the HeartGuide works is there’s a secondary, inflatable strap that works as a miniature cuff on your wrist. All you have to do is hold your arm at chest level—sort of like you’re doing the Pledge of Allegiance—and press the top button on the right side of the watch. Then presto bingo bango, a reading of your systolic and diastolic pressure appears on the screen. If you’re in a healthy range, you’ll see a green border. But if your blood pressure is high, it’ll be red. Readings can then be synced to Omron’s accompanying HeartAdvisor app.

One thing I was wondering about was battery life with something as mechanical as this... The battery is solid, however. Omron says the typical user can expect to charge about 2-3 times per week, depending on how often they take their blood pressure. In real life testing, taking measurements about twice a day, it lasted about three days before needing a charge.

But it's not all roses and sunshine - see more detail at…

Ranking Juices By How Healthy They Are - Surprise! Most juices are less fix-all tonics, more sugar-overdose fructose bombs

Date Published: Fri, 29 Mar 2019 19:35:46 +0200

Juice is something of an anomaly. It generally contains healthy ingredients, like fruits and veggies, yet as we’ve seen time and again, the processes that these fruits and veggies undergo to become juice takes them out of the “healthy” category and into, at best, “meh?”

Overall, juice is much less healthy than you might think. “Most fruit juices, especially those without pulp, are unfortunately sugary beverages,” Hunnes explains (in many cases, fruit juices contain just as much sugar as soda). “Yes, it’s a healthy sugar, because it comes naturally from the fruit, but still, some juices can have upwards of 150 calories per cup, which is similar to soda. I wouldn’t recommend drinking juice on a regular basis if you can eat the fruit instead, which is much healthier because it contains the fiber, pectin [which can lower cholesterol and might prevent cancer] and other nutrients that synergistically make the fruit better than the juice.”

But as with anything — even plain old vegetables — some juices are healthier than others so the article below does at least what juices it is best to aim for.

Secure Your Linux Server With Fail2Ban [Beginner’s Guide] - Helps in securing your Linux server against malicious logins

Date Published: Fri, 29 Mar 2019 18:34:42 +0200

If you have enabled SSH, please check the login history of your Linux server. You’ll be surprised to see a huge number of IPs that try to login to your server via SSH.

If you have no mechanism in place to deter these login attempts, your system is susceptible to brute force attack. Basically, a script/bot will keep on attempting SSH connection your system by trying various combinations of username and passwords.

This is where a tool like Fail2Ban comes into the picture. Fail2Ban is a free and open source software that helps in securing your Linux server against malicious logins. Fail2Ban will ban the IP (for a certain time) if there is a certain number of failed login attempts.

Fail2Ban works out of the box with the basic settings but it is extremely configurable as well. You can tweak it to your liking and create filters and rules as per your need.

It's always the first thing I install after I set up any hosting server... and it's ready to run straight out of the box.

See the guide at…
