Exactly. If you're taking 9-figure investments, you ought to have a sustainable business model sorted out by now. At that level, raising more is supposed to be for things like accelerating growth in existing markets or expanding into lucrative new markets that have high barriers to entry, i.e., work that builds on an existing successful formula. Investing that kind of money in a business that couldn't survive without it was always a dubious proposition.

Indeed, all these mesh network fanatic seem to forget that outside the densely populated cities where they live there are vast sparsely populated areas. How does your mesh network reach those areas without being prohibitively expensive?

Even within densely populated areas, the technology doesn't scale well. This only works well at a very specific device density. Field testing has shown that much above or below this density, the performance of the system becomes badly sub-optimal.

It should also be noted that at no density is the technology performance competitive with hardwired providers. This is because as the density goes up, you need more and more primary gateway routers to keep the link latency and link saturation down. This turns out to be right around 2.2 hops per primary access (hard-wired) nodes. In practice, this requires so many hard links that you don't save much compared to just providing hard links to every home, and everywhere that mesh technology is economically viable, hard wired access is also economically viable and vastly superior in performance.

Lastly, the technology is highly susceptible to spectrum poisoning. The only good solution to that is to have a dedicated piece of spectrum for just mesh technology, but that spectrum would be worth close to $100B, and that alone renders the technology completely uneconomical. Current mesh solutions use the 2.4GHz and 5GHz bands, but both of those are also used by just about every home wifi that is included with any type of Internet access. This punches holes in the mesh that cannot be effectively compensated for. This is only going to get worse as the IOT becomes more and more prevalent.

There are a few mesh networking startup providers that I am aware of, and all of them are plagued by poor performance, poor profitability and poor service reliability. I fully expect the introduction of 5G wireless spectrum from the established cellular carriers to put the final nail in the mesh coffin.

Java (like Flash) was always designed as a plug-in, running side by side with the browser, not an integrated part of the browser. T

Uh, what?

Just because Sun developed a Java plug-in doesn't mean that Sun's vision was ever that Java was primarily supposed to be used that way. Java has always meant to be used as a standalone programming language, and the percentage of Java development targeted at the plugin is absolutely tiny. Most of it is focused on back-end applications, websites, and the occasional desktop app.

I'm not sure where this "Java = applets" thing comes from, and it's especially hard to understand why software developers would think this given it's pretty hard to work in this industry for more than a few years without being given a Tomcat/etc application hosted in a JBoss environment to fix up.

It's not just free overtime.

That is often very much what being on a salary means in practice: you get X money per day/month/whatever, and X doesn't increase if you work more than your normal hours. However, it's also not unusual for salaried employees to have those normal working hours specified in their employment contracts, effectively putting a lower bound on the amount of working time expected in exchange for the salary.

Again, though, this all depends very much on where you are and how your local labour laws work. For example, the US system of at-will employment is actually closer to what most of the world would consider contract or freelance work than employment, typically involving very little commitment to continuing the relationship by either side and relatively low benefits for employees beyond their pay cheque. What is particularly unusual in that case is that in much of the US such an arrangement seems to be the norm even for entry-level and low-paid work. Elsewhere, employment tends to involve much more of a commitment from both sides for those kinds of jobs, while the lighter touch arrangements tend to be used more for skilled professional work. In that context, abusive hiring and firing is usually less of a problem, and all parties may benefit from the greater flexibility, including flexibility about compensation arrangements.

I fully agree, and will re-emphasize what I said about company discretion. Learning new things on the company dime is not an issue, especially considering that it mainly helps the company. TFA explicitly states working on personal projects while making money for a company in any meaningful way. Self education, blowing off steam, or simply unplugging to let the brain relax before heading back to a complex issue.

It should be positively encouraged. I also believe offices should be furnished with beds, so we can take a nap when we want. And we should all have an additional computer with an up to date graphics card and 4K monitor that we can install Steam on.

This seems reasonable to me. What say you, fellow programmers?
