Reorienting MRO Massively Increases Its Subsurface Scanning Power
Orientation is more important than most people thing when it comes to sensing. A common example would be when the lasers of a garage door are mis-aligned, forcing the door to remain open until they are brought back in line. But when it comes to scientific sensors, orientation is even more important. So it was with great fanfare that NASA announced a new way to orient sensors on one of the most venerable of its spacecraft - the Mars Reconnaissance Orbiter (MRO) - and the resultant scientific discoveries it enabled.

«I guess the main point is understand the data types you’re using. You wouldn’t use an 8-bit integer to handle values in the thousands, but it’s fine if the values stay under one hundred. The same rules apply to floating point. You just have to know how they work.» […]

I think "context engineering" is going to stick - unlike "prompt engineering" it has an inferred definition that's much closer to the intended meaning, which is to carefully and skillfully construct the right context to get great results from LLMs […]

The Intel 80186 was to the Intel 8086 what the 68010 was to the 68000: a small improvement that almost made it into the original design but was issued as a different chip… and almost nobody used them, and waited for the 80286/68020 instead […]

Attached: 1 image Today, we’re back at the Practical Classics resto show at the NEC in March with another Polish car, the FSO Polonez. When it was launched in 1978, it had quite a fresh modern look, especially compared with most other Eastern European cars of the time, although most of the under-the-skin bits were carried over from the older 125P, which FSO built under licence from Fiat. Endless updates and variations produced this blander look on later versions. #davidsdailycar #FSO #WeirdCarMastodon

I set up a Timelapse on the roof yesterday but then one kid started screaming, and then the other kid staters screaming, and then the first kid started screaming again because the other kid was screaming, and I tried so hard not to scream that I forgot it was up there so here you have hours.

Die Universitätsbibliothek in Aberdeen ist sensationell. Einer der schönsten Orte zum Lernen, die ich je gesehen habe. #scotland
Blick von oben durch ein siebenstöckiges Atrium hinunter zum Erdgeschoss; die geschwungenen, grob dreieckigen Öffnungen der Etagen sind gegeneinander jeweils etwas verschoben und gedreht; ihre weißen Begrenzungen kontrastieren mit einem dunkelgrauen Teppichboden. Zwei Etagen tiefer läuft eine junge Frau mit Smartphone. Am Bildrand in den oberen Etagen kann man weiße Bücherregale erahnen.Das Bibiliotheksgebäude von außen: ein Würfel mit einer Glasfassade, bei der sich senkrechte, unregelmäßige Streifen von Weiß und blassem Grün in einer Art Zebra-Muster abwechseln.Waagerechter Blick durchs Atrium; man sieht neben der eigenen Etage auch eine darüber und darunter, verbunden mit einer senkrechten Säule mittig im Bild. Auf jeder Etage breite, weiße und in warmem Licht angestrahlte Bücherregalreihen und am Rand Tische mit ein paar Studierenden.
