Congress is considering a bill that will increase the minimum wage for H-1B visa holders to $100,000 per year. This is an attempt to discourage businesses from hiring immigrants who require sponsorship, instead of hiring American workers. At least that’s what congress says H.R. 170 will do. However, I think what we’ll actually see are large companies in tech hubs like the bay area, Seattle, Chicago, New York and others, start to absorb the largest swatches of the immigrant talent pool, while shorting smaller companies and public sector jobs from the same access to skilled workers.
In January of 2017, three black eighteen year old males and one black eighteen year old female abducted a white, mentally handicapped man of the same age. The four of them abused him for somewhere between one and two days. They made him drink toilet water while yelling, “fuck trump” and “fuck white people.” They broadcast this on Facebook’s live streaming service. The kidnapping, abuse and hate crime charges they face could put them away for years. We are looking at the effects of the false left right paradigm, and of government propaganda, directly turning Americans against one another.
For the past couple of years, we’ve seen a substantial amount of research committed by the tech and auto industry into self driving vehicles. Billions of dollars are being spent on a solved problem; depending on how you view the problem. If the domain of the problem is transportation and increasing populations within metropolitan areas, automated driverless trains have been a reality for quite some time. I’d argue that solving the domain space of individual automated cars, while contributing significantly to the fields of machine learning and computer vision, is a wasted effort when it comes to sustainable transportation solutions for the planet.
Earlier this year, I decided to build a development desktop. It’s the first PC I’ve fully built in at least four years. While I was backpacking, I relied solely on my laptop for development work. Prior to that I had used desktops people were giving away, or systems I had build years ago and had just continually upgraded. Since this would be a Linux workstation aimed primarily at development, the hardware was focused on performance. It would be built with 32GB of DDR4 memory, a 6700K i7 processor and dual M.2 solid state NVME drives connected to the PCI-E bus in a software RAID0 (striped) configuration for performance.
Mesosphere DC/OS is a data center operating system, based on Apache Mesos and Marathon. It’s designed to run tasks and containers on a distributed architecture. It can be provisioned either on bare metal machines, within virtual machines or on a hosting provider (what some people like to call “the cloud.”). I wanted to see what was involved in setting up my own DC/OS instance, both locally and with a provider, for running some of my own projects in containers. I wanted to keep this cluster as low cost as possible, and ran into some issues with the Terraform installation in the DC/OS documentation. The following is a brief look at setting up a minimal DC/OS cluster on Digital Ocean.
I had been using a Banana Pi BPI-R1 as my router. Due to some reliability issues, I attempted to replace it with a ClearFog Pro, which also met with unfavorable results. Many hobbyist tend to use old PCs as routers, as I have in the past. Due to some scaling down, I no longer have a bucket of spare parts to build a low powered Linux box. Instead of going with another ARM solution, I decided to build a custom x86_64 system based on the Thin-ITX form factor. I discovered that a x86/Thin-ITX solution was more reliable than the ARM alternatives I have tried, and ran the same cost as a high end home router.
Back in February, I decided to use a Banana Pi BPI-R1 as my primary router. There wasn’t a lot of documentation on setting up the R1 as a router, and understanding the port/vlan mapping was a little complicated, so I wrote a tutorial. The BPI-R1 only has one Gigabit Ethernet controller, shared between the WAN and LAN ports and configured via vlans, which I found could result in potential security issues. Due to stability and security issues, I decided to purchase a ClearFog Pro, which featured separate Ethernet adapters for its switch, primary and SFP port. However, what I soon found was a disappointing mess of hardware and software. The manufacturer has refused my request for a return, leaving me with a $240 USD worthless brick.
Previously I had written a guide to using a Banana Pi BPI-R1 as a router. As I write this, I’ve been running the BPI-R1 as my home gateway/firewall for approximately nine months. Initially I had problems with the router freezing and needing to be power-cycled every few weeks. Although this is somewhat commonplace and accepted on consumer commodity routers, it shouldn’t be necessary on a piece of hardware designed for hobbyists. Furthermore, there were other stability and hardware issues that could cause the BPI-R1 to reboot as a switch, with public IPs being assigned to internal machines. This effectively disabled the firewall, leaving internal machines in a potentially vulnerable state.
I recently I purchased a 4K monitor which I intended to use with both my laptop and my desktop. Both machines support a resolution of 4096x2160 over their respective display ports. Individually, each machine works well with the monitor, the Windows laptop being able to drive it at 50Hz and the Linux desktop able to drive it at 60Hz. I’ve owned many KVM switches in the past without major issues, so I was surprised to learn that using a KVM with a 4K/UHD monitor proved to have significantly more challenges than previous interfaces.
