Just an example https://www.newegg.com/p/2SW-003Z-00008 but countless examples on amazon,newegg,aliexpress

It seems to even support two 4k monitors (probably in 60hz)! And they advertise up to 3 monitors support.

This is running a 5257U which is an ancient 5th gen mobile chip and even with the Iris graphics it got (much better than the usual Intel HD) only HDMI 1.4 is supported.

> You can get considerably more powerful mini PCs for less than a 4GB Pi5 with needed accessories that is upgradable, has further software support, and includes all of what you need to get with a Pi. Name three, please, with emphasis on the "considerably more powerful" part.

Sure...but it might take me a while...how about this, I'll name...as of current, 385 under $100 all with free shipping: https://www.ebay.com/sch/i.html?_from=R40&_nkw=mini%20pc&_sa... The Pi5 is slower than a Core i3 6100, does not support upgradable ram, does not support Pci Gen 3 let alone Gen 3 x16, no actual Sata 6, no upgradable sockets, etc. There are a TON of uses cases for a Pi 5...but only really if power co…

Someone buying used electronics on eBay has already decided that their time is worthless and the hardware doesn't need to be dependable out of the box. Which is fine, those are decisions a person could make, but it's just disingenuous to compare the value of one thing to another without taking the you are using someone's untested trash factor into account.

Please stop using “average” for wage comparisons. It’s an utterly useless metric for showing if wages are moving or not. If you must use average, then you should remove the top 5% from the average.

> If you must use average, then you should remove the top 5% from the average. 5% is too arbitrary, just use the median.

median is a type of average. the parent commenter means the mean

I see that the PR against the Raspberry Pi linux repo is out [0]. Interestingly they are introducing a BCM2712 defconfig with a 64k default page size.

From the device tree [1] it looks like they've rolled their own IOMMU rather than using ARM's SMMU which is annoying.

Beaglebone (from Texas Instruments) is more open, but still not as open as you'd probably like. Still, its a better balance than what Rasp. Pi organization has (more documents are available on AM335x, open-hardware for Beaglebone Green and reference designs, full chip specifications and the like). Beaglebone isn't really "more expensive", as much as its just "lower specs at the same price" though. The "most open" are…

I always thought the beaglebone had a better hardware design. The thing I first noticed was the female header pins - why would the pi have pins that can be shorted out? the beaglebone pru is cool too. But all of that pales in comparison to the huge mindshare the pi has, which makes all the difference.

Maybe, maybe not.

RP4 doesn't have LoRA like the Beaglebone Play. 3mile / 5km radios can do many things that RP can never do.

> This device has a PCIe 2.0 x1 connector now, so NVMe drives should be usable now. It's a fiddly FPC connector though, which isn't a great contributor to mechanical robustness.

FPC is used in billions of devices with perfectly fine robustness. As long as it isn't part of some flexible mechanism (e.g., a flex display, or something folding), it should be just fine. If you toss it into a box with the FPC flopping in the breeze then I'm sure it would be terrible, but... don't do that?

FPC is used in billions of devices-- that are professionally assembled, usually assembled only once, well-enclosed, and careful attention has been given to strain relief. It's cheap and compact and allows very small assemblies.

It's not so hobbyist/tinkerer friendly, where you're likely to put a lot of cycles on the connector, bend things back and forth, and end up with an enclosure that does not protect everything as well as one would like. Indeed, you have a sibling comment talking about breaking lots of FPC going to cameras.

Mechanical/connector failure is a small but noticeable share of the SD robustness problems on SBCs. I would expect FPC to be worse.

No word on price. When Raspberry Pi first launched, this was the prime feature of the thing. Can we expect same price as the Raspberry Pi 4? (at the respective RAM level) Edit: found it here: https://www.raspberrypi.com/news/introducing-raspberry-pi-5/ So the 4 GB model is 60$, which is 5$ more than the 4 GB model of the Raspberry 4 when that was launched: https://www.raspberrypi.com/news/raspberry-pi-4-on-sale-now-.…

My gripe is that the original Pi cost $35 at launch and while they have made a better Pi...They have not made a Pi at that price ever again, even accounting for Inflation. Furthermore, increased power consumption and features have added big price jumps to the required Accessories. Now you need miniHDMI adapters rather than more common HDMI, you need cooling, you need more expensive power adapters. a fully set up Pi 1 was simple USB, SD, and HDMI All possible in a $50 budget or less if you had some stuff. Now you are $90 in to run it.

Given outliers in a skewed dataset, wouldn't median be a worse description than mean without outliers? https://openstax.org/books/statistics/pages/2-6-skewness-and...

The answer is always "it depends", which is exactly why I prefer the median in most cases. Once you choose to use the median, there are no more choices/degrees of freedom - it's just the median. On the other hand, "mean without outliers" requires you to make a subsequent value judgement on what exactly is an "outlier".

> "mean without outliers" requires you to make a subsequent value judgement

Do you think that comparison of outliers to interquartile range is not a relatively objective method of determining outliers?

The interquartile range is a number that indicates the spread of the middle half, or the middle 50 percent of the data. It is the difference between the third quartile (Q3) and the first quartile (Q1) . . . The IQR can help to determine potential outliers. A value is suspected to be a potential outlier if it is less than 1.5 × IQR below the first quartile or more than 1.5 × IQR above the third quartile. Potential outliers always require further investigation.

Same as the people on Reddit claiming that Raspberry Pi has killed itself as a business because it's constantly in such high demand that it's always sold out.

They're claiming that they've killed themselves as a business hobbyists, which isn't exactly wrong. During their supply chain issues they made it clear they were prioritizing their commercial customers over the hobbyist market. At this point the hobbyist community has moved on to other things (shout out to odroids). I don't think raspberry pi is going anywhere, but they do have a very different market and customer ba…

Are there any odroid-based PiKVM-like devices? The PiKVM device is really well built and the software is good. Easiest thing for me to LetsEncrypt too.

I suspect the speculator and reseller markets are already abuzz with figuring out how to stockpile and control the distribution like they did during the pandemic and various video game releases. This ought to be fun to watch.
