I love this research on schizophrenic files (and polyglots in general), but I feel that the scenario in the quoted post is maybe too convoluted to happen in real life.

It needs lots of recon to know which zip software each person in the chain will be using;โ€ฏand at this point, spear-phishing and others become lower cost than crafting custom files with the associated QA.

I've referenced it enough that now it's all I can hear when I read it. Now you have to hear it too ๐Ÿ™‰ https://ericwbailey.website/published/you-must-listen-to-rfc-2119/
You MUST listen to RFC 2119

It turns out you can just pay people to do things.

Classic enterprise: we saved money by moving from on-premise to Cloud.
Me:โ€ฏgo on...
Classic enterprise: yeah, when we saw the bill go up, we had an emergency task force to optimize usage.
Me: why didn't you do that before?

One of the strengths of the Cloud, not to be underestimated: immediate cost feedback.

'On November 28th, 2012, Randall Munroe published an xkcd comic that was a calendar in which the size of each date was proportional to how often each date is referenced by its ordinal name (โ€ฆ) "In months other than September, the 11th is mentioned substantially less often than any other date. It's been that way since long before 9/11 and I have no idea why." After digging into the raw data, I believe I have figured out why.'

I love how Apple will now be repeating every security mistake by writing their own container runtime. I thought we're past all that but hey, let's have some more path lookup CVEs. @cyphar

mount /dev/console by elijah-wright ยท Pull Request #173 ยท apple/containerization

fixes #145 this PR changes configureConsole() to bind mount /dev/console if process.terminal is true. I couldn't think of a better way to get the pty path so I used readlink. most OCI images do...

So, on average, poll respondents guessed that a Netflix Open Connect server uses ~2.3W per simultaneous user. Based on some real user feedback & https://openconnect.netflix.com/en/appliances/#the-hardware, the number is probably closer to 20mW. It could even be a lot lower. So the right answer is definitely "<0.5W"!
Hunting down bugs on embedded systems is not always fun. That one was.

Deep Down the Rabbit Hole: Bash, OverlayFS, and a 30-Year-Old Surprise

This blog post describes a recent debugging session that led through a surprising set of issues involving Bash, `getcwd()`, and OverlayFS. What started as a simple customer bug report turned into a deep dive worth sharing.

@vbabka what did you expect? Something like this? ๐Ÿ™ƒ
Hat tip to John Kemp for admitting that he was wrong to blame Spain's blackout on excessive reliance on inverter-based renewables and insufficient inertia, and ๐Ÿ‘ for his very decent explainer on what actually happened. https://jkempenergy.com/2025/06/19/spains-blackout-blamed-on-poor-voltage-control/
Spainโ€™s blackout blamed on poor voltage control

19 June 2025 Spainโ€™s massive blackout was caused by overvoltage on the transmission system and the failure of the countryโ€™s generators to compensate by absorbing more reactive power, according to tโ€ฆ

@bert_hubert Economy of scale basically as the content isnโ€™t delivered individually until the last few miles basically
@BenBen @bert_hubert open connect *is* the last mile server for this purpose.
@bert_hubert That is a bit misleading, since the servers are not really the energy intensive part of the operation. The network towards the user requires a lot more power... but that can wildly fluctuate depending on the last mile. So it's more for copper or radio because of the expensive signal processing, and much less for optical connections.
@casandro I worded it very specifically for people like you. Reread the poll if in doubt. It was about nothing other than the server.
@bert_hubert Yes, absolutely, but companies like Netflix commonly use such facts for Greenwashing. They are technically right, but create a wrong impression in the uncritical mind.

@casandro @bert_hubert

Imagine doing it at Netflix' scale - the OCA appliances are actually a pretty sustainable architecture.

The appliances are filled once and from there the content is available closer to the consumer.

Now, imagine that Netflix didn't have or used those appliances - how is that more sustainable?

@casandro @bert_hubert

Fortunately, Netflix isn't in charge of the last mile. They have quite optimized the content - their bitrate is lower than part of the competition.

@h3artbl33d @bert_hubert Well comparing that to normal satellite broadcast television. It's very unsustainable. There you can provide an area like Europe with a DRM-free copy of a movie or TV series... with just a few hundred watts in total.

@bert_hubert I suspected. And we get shamed for streaming 4K (by whomever last bought into the carbon footprint nonsense).

Any TV screen (and audio amp) uses way more power than the network streaming does.

@holsta @bert_hubert It is not only the server but also all the rest of the infrastructure between the server and the client. All in all there is quite a bit of overhead.
@alterelefant @holsta Which is why I worded the question very specifically.

@bert_hubert @holsta I get that.

Most people just have no clue how much energy is used (or wasted) in networking, local and long distance.

@bert_hubert Unluckily I see everywhere a lack of knowledge and interest for such topics.
