Agrivoltaics Is A Land Usage Hack For Maximum Productivity

Land tends to be a valuable thing. Outside of some weird projects in Dubai, by and large, they aren’t making any more of it. That means as we try to feed and power the ever-growing population of humanity, we need to think carefully about how we use the land we have.

The field of agrivoltaics concerns itself with the dual-use of land for both food production and power generation. It’s all about getting the most out of the the available land and available sunlight we have.

“The Era Of Distributed, Independent Email Servers Is Over”

Imagine the Internet had begun its life as a proprietary network from a major software vendor rather than evolved as a distributed network shared by researchers. It’s a future that almost came to pass for consumers in the 1990s when walled gardens such as AOL or the original incarnation of MSN were all the rage, but thankfully the world took the Internet course.

Though there are many continuing threats to Internet freedom we can still mostly use the network our way, but with sadness we note that one piece of Internet freedom may have drawn to a close. [Carlos Fenollosa] has written a lament about how the outlook for anyone running their own mail server now looks bleak.

At its heart is spam, or indeed the heavy-handed measures taken by large email providers to combat it. Spotting and canning spam is computationally expensive, so the easiest way to stop a spammer is to recognize their activity and block it at the network level. Thus a large email provider will instantly block large IP ranges when it detects they hold a spammer, with the collateral damage of also blocking any legitimate email servers in the same range such that their mail just doesn’t get through. Since spam is such a widespread problem, as [Carlos] points out it’s less of a case of if your server has this problem, but when. This functions essentially as something of a racket, in which large email providers have the power to ensure that any email not generated from amongst themselves is unlikely to reach any of the millions of addresses under their care, and the only recourse an operator of a small email domain has is to use the services of one of them.

He has something of a manifesto as to how this problem can be addressed, and we think that it’s important enough that you should take a look. Maintaining email as something beyond the control of large providers is too important not to.

Thanks [Thomas Steen Rasmussen] for the tip.

Organise Your Hacks With TreeSheets: An Open Source Hierarchical Spreadsheet

Some people may have heard of Dutch programmer [Wouter Van Oortmerssen] since he’s the creator of the Amiga-E programming language, as well as being involved with several game engines. Heard of SimCity? How about Borderlands 2 or Far Cry? Having had clearly a long and illustrious career as a programmer for a variety of clients — including a long stint at Google, working on Web Assembly — many people will be familiar with at least some of his work. But you may not have heard of his TreeSheets productivity tool. Which would be a shame, as you’ve been missing out on something pretty darn useful.

TreeSheets is described as a hierarchical spreadsheet, which is intended as a replacement for several distinct tools; think spreadsheets, mindmaps and text editors and similar. In [Wouter]’s words:

It’s like a spreadsheet, immediately familiar, but much more suitable for complex data because it’s hierarchical.
It’s like a mind mapper, but more organized and compact.
It’s like an outliner, but in more than one dimension.
It’s like a text editor, but with structure.

Having been in development for about a decade, TreeSheets might look a bit dated here and there, but the design is clear and distraction-free, which is exactly what you need when you’re trying to focus on the task in hand. Why not give it a try and see if it works for you? After the break, you can see a video tutorial by YouTube user [DrilixProject].

No strangers to productivity hacks, here’s Pomodachi, a cute pomodoro timer crossed with a Tamagotchi. Sometimes productivity isn’t solved with software tools, but more to do with your attitude to projects. Finally sometimes the route to greater productivity is a little closer to home, like inside your head.
