While all the hype might make you think that Bitcoin is the only cryptocurrency, there are a number of alternatives out there and this piece in Fortune outlines what they are: 5 Bitcoin Rivals That Are Rapidly on the Rise.
While this piece lists a handful, I expect that there will be a flood of such things in the future as financial markets look to capitalize on this mixture of money and technology.
The Fortune piece is also not bad in summarizing some key facts about Bitcoin if you still find it hard to get your head around it.
I expect Bitcoin to crash to a much lower level, but I don’t see cryptocurrencies going away. Knowing more about them, especially because they could have a major impact on global economies, is worthwhile.
According to CNET: Delivery robots face strict rules in San Francisco.
I like that picture above. Often when I see delivery robots in photos, they are by themselves on an uncrowded street. In the photo above, you can get a better sense of how it will be a problem if swarms of these things start taking over the sidewalk. The idea of sidewalks becoming more crowded by these tiny vehicles is a maddening one.
I’d be fine with them if city planners can come up with a way these robots can roll around and not impede better uses of the streets such as walking and cycling and public transit. Until then, the less robots crowding the sidewalks, the better.
Like drones in the air and autonomous cars on the roads, robots are coming to the sidewalks. City planners need to start planning for that now.
I thought this piece was great: This ex-trucker has some questions about the Tesla Semi – Autoblog.
It punctures the hype behind Tesla’s new truck in the best possible way, by carefully and methodically asking questions and bringing up real life experiences that show the limitations of the truck.
Too few tech reviews come with this type of analysis. I’d like to see more of it. Most tech reviews are positive summaries of features. Or there are a small number of pieces that say such and such will never work because I say so. In either case, the person reviewing it comes from a technology background. I’d like to see more non-technical reviews of technology.
If you are interested in Tesla or the direction of automotives, it is well worth a read.
I am unexcited about the direction in Smartphone design. The key design idea that less is more in a phone is becoming Less is a Bore. Perhaps that’s why this design of a Blackberry got me thinking about it. While it still has a gorgeous screen, the phone itself is worthy of looking at and touching. It strikes the right balance. The phone as a design object is worthwhile.
It would have been good if Apple had struck out in a new design direction with the iPhone X. Instead they went with Less is More. Instead we have a phone with the Notch and a camera on the back that sticks out. It’s as if Apple would have preferred not to have these cameras and sensors, so rather than design the phone to incorporate them into the design, they stick out, figuratively and literally. In a few years from now when Apple has gone in a different direction, Apple fans will look back and exclaim how poor that aspect of the phone design is.
As for now, we live in an age where the screen dominates design, from TVs to smartphones. In the future that may change and the technology that we interact with will be contained in objects that have noteworthy design in them.

And you can get it here: blm849/supersimplehardening: A super simple way to harden your server.
I create a lot of Ubuntu test servers, and I find that as soon as I create a Ubuntu server on a cloud environment, it gets immediately attacked by automated software. This is obviously a concern. A bigger concern is that when I went searching for recommendations on how to harden such a server, I found a wide variety of recommendations! It can be hard to know what to do. Still, I needed something. As a result, I created this package of scripts. The scripts do a number of things:
- prevent direct root login to your server via ssh. This was one of the things I saw consistently happen and once someone cracks the root access on your machine, it’s game over.
- stop some basic security holes, like IP spoofing
- download some useful software, like logwatch, ufw and others
- upgrade all software on the server
This is just a very very limited number of things to prevent attacks. But it is better than nothing.
If you install Apache, PHP, MySQL or other software on your machine, there are even more attacks that will be launched against it. I recommend you get a firewall up and running and at least run logwatch on a regular basis to look for potential attacks being launched against you.
Finally, if it is important for you to secure your server, don’t stop with my scripts. Go out and consult with IT security specialists right away.
