Help.
I'm a hardware guy. If I do software, it's bare-metal (almost always). I need to fully understand my build system and tweak it exactly to my needs. I'm the sorta guy that needs memory alignment and bitwise operations on a daily basis. I'm always cautious about processor cycles, memory allocation, and power consumption. I think twice if I really need to use a float there and I consider exactly what cost the abstraction layers I build come at.
I had done some web design and development, but that was back in the day when you knew all the workarounds for IE 5-7 by heart and when people were disappointed there wasn't going to be a XHTML 2.0. I didn't build anything large until recently.
Since that time, a lot has happened. Web development has evolved in a way I didn't really fancy, to say the least. Client-side rendering for everything the server could easily do? Of course. Wasting precious energy on mobile devices because it works well enough? Naturally. Solving the simplest problems with a gigantic mess of dependencies you don't even bother to inspect? Well, how else are you going to handle all your sensitive data?
I was going to compare this to the Arduino culture of using modules you don't understand in code you don't understand. But then again, you don't see consumer products or customer-specific electronics powered by an Arduino (at least not that I'm aware of).
I'm just not fit for that shooting-drills-at-walls methodology for getting holes. I'm not against neither easy nor pretty-to-look-at solutions, but it just comes across as wasteful for me nowadays.
So, after my hiatus from web development, I've now been in a sort of internet platform project for a few months. I'm now directly confronted with all that you guys love and hate, frontend frameworks and Node for the backend and whatever. I deliberately didn't voice my opinion when the stack was chosen, because I didn't want to interfere with the modern ways and instead get some experience out of it (and I am).
And now, I'm slowly starting to feel like it was OKAY to work like this.10 -
No actual data loss here, but the feeling of data loss.
After having my data scattered across several devices i decided to get a grip on it use a cloud. I'm too paranoid for a real cloud so i used a local nextcloud installation. That was done via docker and with a 2TB raid1-array.
I noticed that after restarting the server the cloud was somehow reset and pointed me to the setup-page, afterwards my files were already there. It did strike me as odd but i figured "maybe don't restart the server in the next time".
But i did restart it. And this time i had to setup the cloud again, but my files were gone. I got close to a heart attack, even though all those files weren't that valuable. I ripped one disk from the usb hub, connected it to my laptop and tried to mount it, but raid array. Instead i started photorec and recovered a bunch of files, even though their names were some random hex and i knew i'd spend my next weeks sorting my files. While photorec ran i inspected the docker container and saw that there were only 10GB of space available. After a while and one final df i found the culprit: the raid. For some reason the raid wasn't mounted at boot and docker created the volumes on the servers hard disk, same goes for the container data. After re-adding the disk to the hub i mounted the raid and inspected everything again. All my files were still there.
At no point did i lose my data, but the thought was shocking enough. It'd be best not to fiddle with this server in the next time. -
The Use of Recycled Heart Devices
There are many controversial issues in the healthcare, and some of them seem so debatable that it is difficult to chose which side to support. One of such issues is the use of recycled heard devices – implantable cardioverter-defibrillators (ICDs) that were previously used by people who could afford them and changed them to a new model or died. These devices are still in good condition and have some battery life remaining. Scientists like Pavri, Hasan, Ghanbari, Feldman, Rivas, and others suggest that these ICDs can be reused by those patients who cannot pay for them.
The issue has caused many arguments. Federal regulators and ICDs manufacturers in the United States prohibit the practice of such a reuse; however, it is allowed in India, where very few people can afford defibrillators. The use of recycled ICDs can be regarded as inferior treatment to the poor. People who cannot pay for the expensive devices still deserve the healthcare of the highest quality as any wealthy person. For this reason, other means of providing healthcare to poor people should be found as it is unethical to make them feel humiliated or deprived of medical aid guaranteed to them by the Declaration of Human Rights. Harvard medical experts claim: flagship projects must remain free of the taint of the secondhand, in part by making it clear when devices can safely be reused.
These scientists also doubt the safety of ICDs reuse. Despite the fact that all devices are carefully transported and sterilized, there is still a danger of infection transmission. The experts, for instance, claimed that three people died because of stroke, heart failure, and myocardial infarction. Though it is not proved to be caused by recycled ICDs, there is no evidence about the relevance of the reused devices to these deaths. It can be presumed that the failure of the defibrillator did not prevent the problem. In general, their findings prove that the alternative reuse of ICDs is a comparatively riskless life-saving practice.
There is another side of the problem as well. It is obvious that human life is sacred; it is given to one person only once, so it should be protected and preserved by all means (humanlike, of course) possible. If there cannot be another way out found, secondhand ICDs should be applied to patients who cannot pay for their treatment. If the world is not able to supply underprivileged patients with free devices, richer countries can, at least, share what they do not need anymore. One may draw a parallel between recycled defibrillators and secondhand clothes. There is nothing shameful about wearing things that were used by another person. Many organizations supply children in poor countries with garments in a good condition that richer people do not wear anymore. For the same reason, reused defibrillators in a proper state can be implanted to those patients who cannot afford new devices and will not be able to survive without them. Underprivileged patients in some developing countries receive alternative treatment of drug therapy, which, in this case, can be regarded as inferior method. Apparently, if to consider the situation from this viewpoint, recycled heart devices should be used as they allow saving people’s lives.
The use of recycled implantable cardioverter-defibrillators is illegal and risky as they are classified as single-use devices. Moreover, despite the fact that the results of researches on the topic proved to be positive, there were cases when some people with recycled ICDs died because of stroke, heart failure, or myocardial infarction. It is unethical to break the law, but at the same time, person’s life is more important. If there is no other possibility to save a person, this method must be applied.

9 Ways to Improve Your Website in 2020
Online customers are very picky these days. Plenty of quality sites and services tend to spoil them. Without leaving their homes, they can carefully probe your company and only then decide whether to deal with you or not. The first thing customers will look at is your website, so everything should be ideal there.
Not everyone succeeds in doing things perfectly well from the first try. For websites, this fact is particularly true. Besides, it is never too late to improve something and make it even better.
In this article, you will find the best recommendations on how to get a great website and win the hearts of online visitors.
Take care of security
It is unacceptable if customers who are looking for information or a product on your site find themselves infected with malware. Take measures to protect your site and visitors from new viruses, data breaches, and spam.
Take care of the SSL certificate. It should be monitored and updated if necessary.
Be sure to install all security updates for your CMS. A lot of sites get hacked through vulnerable plugins. Try to reduce their number and update regularly too.
Ride it quick
Webpage loading speed is what the visitor will notice right from the start. The war for milliseconds just begins. Speeding up a site is not so difficult. The first thing you can do is apply the old proven image compression. If that is not enough, work on caching or simplify your JavaScript and CSS code. Using CDN is another good advice.
Choose a quality hosting provider
In many respects, both the security and the speed of the website depend on your hosting provider. Do not get lost selecting the hosting provider. Other users share their experience with different providers on numerous discussion boards.
Content is king
Content is everything for the site. Content is blood, heart, brain, and soul of the website and it should be useful, interesting and concise. Selling texts are good, but do not chase only the number of clicks. An interesting article or useful instruction will increase customer loyalty, even if such content does not call to action.
Communication
Broadcasting should not be one-way. Make a convenient feedback form where your visitors do not have to fill out a million fields before sending a message. Do not forget about the phone, and what is even better, add online chat with a chatbot and\or live support reps.
Refrain from unpleasant surprises
Please mind, self-starting videos, especially with sound may irritate a lot of visitors and increase the bounce rate. The same is true about popups and sliders.
Next, do not be afraid of white space. Often site owners are literally obsessed with the desire to fill all the free space on the page with menus, banners and other stuff. Experiments with colors and fonts are rarely justified. Successful designs are usually brilliantly simple: white background + black text.
Mobile first
With such a dynamic pace of life, it is important to always keep up with trends, and the future belongs to mobile devices. We have already passed that line and mobile devices generate more traffic than desktop computers. This tendency will only increase, so adapt the layout and mind the mobile first and progressive advancement concepts.
Site navigation
Your visitors should be your priority. Use human-oriented terms and concepts to build navigation instead of search engine oriented phrases.
Do not let your visitors get stuck on your site. Always provide access to other pages, but be sure to mention which particular page will be opened so that the visitor understands exactly where and why he goes.
Technical audit
The site can be compared to a house - you always need to monitor the performance of all systems, and there is always a need to fix or improve something. Therefore, a technical audit of any project should be carried out regularly. It is always better if you are the first to notice the problem, and not your visitors or search engines.
As part of the audit, an analysis is carried out on such items as:
● Checking robots.txt / sitemap.xml files
● Checking duplicates and technical pages
● Checking the use of canonical URLs
● Monitoring 404 error page and redirects
There are many tools that help you monitor your website performance and run regular audits.
Conclusion
I hope these tips will help your site become even better. If you have questions or want to share useful lifehacks, feel free to comment below.
