You will have to define "safe", but in general things like infinite loops are effectively bound by the amount of gas provided. Mistakes are still expensive, and it is easy to get the code wrong (the DAO hack and quadrigacx screw u

The article doesn't get the concern of the curlers right. Curling has recently undergone a similar transformation that other sports have gone through over recent decades: the sport has become a lot more athletic. Of course, the sweeper

This is a good heuristic for just about _everybody_. The more people are willing to say "I don't know", the higher the likelihood that they are saying what they really believe to be true when they don't.

Thank you! I actually have become more anal about code quality as I've gone along, to the point of annoying people. IonDB represents a much better coding standard, in my mind than LittleD. Like I say, every bit of documentation and cle

We've actually been looking at getting some newer devices, I'll look to add this to our list. Thanks!

I recently was invited to give a talk about LittleD at the University of Michigan. While there, I got to talk with the one of the lead researchers working on the world's smallest computer, this thing: http://www.eecs.umich.e

You are not wrong, but consider that the problem may be handled a number of ways. Once I move to storing everything through IonDB, you will be able to choose key-value stores that could wear level, should one be implemented. Such algorithms

SQLite has many more features. It has more types, more functions, more SQL support. It also requires significantly more resources; they claim 100KiB of heap space and 4KiB of stack space with at least 300KiB of compiled code, stripped as sm

How little memory have you managed? They claim 100KiB, but if it could be even half that then there are some tremendous opportunities to use it. I'd love to hear more about your work adapting SQLite for Cortex-M-class devices.

If all you need is a key-value store, consider IonDB: https://github.com/iondbproject/iondb

And many of these still don't have enough RAM to make SQLite workable. That said, I look forward to the day when SQLite is the smallest database we will need; its just up for debate when that will occur.

That is one area LittleD needs some improvement. We only support CREATE TABLE, INSERT, SELECT right now. O(1) for inserts because we only append. That said, IonDB was in part motivated to be a storage engine for LittleD. Then you basically

Thank you for the feedback! I actually have a lot of thoughts of ways to improve this too, which is why I am applying to do a PhD in this area.

There isn't really a targeted platform. There just only happens to be one of me at the moment, and so I've only managed to compile it for a few devices. As you noted, its not really an IoT databases. It could be used as such, but

by geedy 11y ago
I did not target "IoT" specifically if I am honest. Its one of the use cases I envision. But sensors and motes would could find just as much use, or anything having to collect and store data to make decisions with over time.

Full disclosure: I am one of the authors of this work. There was some interest in my other research, LittleD ( https://news.ycombinator.com/item?id=10621337 ), and IonDB has been another focus for a few years in the lab I wor

My goal has always been to support a wide-variety of devices. As for the name, I cannot take credit. There is a good story behind it though. ;) As for the need, I sort of explained the motivation this comment: https://news.ycombi

In the example given, it was more about needing to collect data over a large area, such as across multiple city parks. They needed to manage data at the source(s) to inform good watering decisions.

As others have noted, the resource constraints associated with many of the most cost-effective 8/16/32-bit AVR or ARM devices simply cannot run on SQLite. I even looked at making it smaller before starting LittleD, but I deemed th
