The general point here is that your individual behavior as a consumer likely doesn't impact this mechanism. An aircraft doesn't skip a flight just because you waited a week to go on vacation. Aviation infrastructure is something of a fixed-cost which would likely only respond to systemic changes in travel demand, economic impacts on maintenance or fueling, or possibly some other form of regulation (e.g. a penalty for inducing contrails).

>How should the program know?

if we're talking about logs from our own applications that we have written, the program should know because we can write it in a way that it knows.

user-defined config should be verified before it is used. make a ping to port 25 to see if it works before you start using that config for actual operation. if it fails the verification step, that's not an error that needs to be logged.

I don't know about all hyperscalers, but I have knowledge of one of them that has a large enough fleet of atomic frequency standards to warrant dedicated engineering. Several dozen frequency standards at least, possibly low hundreds. Definitely not one per machine, but also not just one per datacenter.

As you say, the goal is to keep the system clocks on the server fleet tightly aligned, to enable things like TrueTime. But also to have sufficient redundancy and long enough holdover in the absence of GNSS (usually due to hardware or firmware failure on the GNSS receivers) that the likelihood of violating the SLA on global time uncertainty is vanishingly small.

The "global" part is what pushes towards having higher end frequency standards, they want to be able to freewheel for O(days) while maintaining low global uncertainty. Drifting a little from external timescales in that scenario is fine, as long as all their machines drift together as an ensemble.

The deployment I know of was originally rubidium frequency standards disciplined by GNSS, but later that got upgraded to cesium standards to increase accuracy and holdover performance. Likely using an "industrial grade" cesium standard that's fairly readily available, very good but not in the same league as the stuff NIST operates.

The difference is between staying on stable and cherry-picking the latest for what you really do need, and being on everything latest.

The latter has a huge maintenance burden, the former is the, as I said already, sweet spot. (And let's not talk about combining stable/testing, any machine I tried that on got into an non-upgradeable mess quickly)

I am not saying it is easy, which is exactly why I think it should be a commercial service that you pay for for it to actually survive.

As always „it depends”

- info - when this was expected and system/process is prepared for that (like automatic retry, fallback to local copy, offline mode, event driven with persistent queue etc) - warning - when system/process was able to continue but in degraded manner, maybe leaving decision to retry to user or other part of system, or maybe just relying on someone checking logs for unexpected events, this of course depends if that external system is required for some action or in some way optional - error - when system/process is not able to continue and particular action has been stopped immediately, this includes situation where retry mechanism is not implemented for step required for completion of particular action - fatal - you need to restart something, either manually or by external watchdog, you don’t expect this kind of logs for simple 5xx

Sure, but water vapor doesn't spontaneously transition to a liquid and accrete onto surfaces - there needs to be a super-saturation of water vapor, and given the temperatures of jet exhaust, that's not trivial to achieve. However, the super-saturation needed for water vapor to deposit onto surfaces as ice is much lower, hence the preference for ice crystal nucleation.

It depends entirely on your use case. If all you need is a DB and Python/PHP/Node server behind Nginx then you can get away with that for a long time. Once you throw in a task runner, emails, queue systems, blob storage, user-uploaded content, etc. you can start running beyond your own ability or time to fix the inevitable problems.

As I pointed out above, you may be better served mixing and matching so you spend your time on the critical aspects but offload those other tasks to someone else.

Of course, I’m not sitting at your computer so I can’t tell you what’s right for you.

> With marijuana it’s not. So until we have a valid method of testing if someone is “too stoned to drive” we have to push back on any attempt to classify marijuana users as ineligible to drive.

I agree. As someone who regularly consumes 250mg of edibles daily at a minimum, I’m sure my levels would be off the charts on a constant basis, even when sober. With the tolerance I currently have, it’d take a ridiculous amount to put me into a state where I felt driving wasn’t safe.

I wish I could emphasize this even more.

There's a lot more where it doesn't and people absolutely to apply any kind of scientific thought to it.

Currently Denmark participates in financing Greenland, pulling the rug on it would likely not be pleasant for the greenlanders and if they did I'd count that as rather dickish unless the greenlanders had a near consensus on the issue and asked the danish parliament to do it.

Well, some justice have been sought and won, but a lot remains. To me it seems like an attempt at distraction to clump together the treatment of the Mau Mau and the nuking of Algeria with Denmark's relation with Greenland.

Besides economic relations, independence for Greenland would also mean that they would need to seek justice to a larger extent through international courts and in at least some cases it's likely easier for greenlanders to find justice in danish courts.

Well, the GPs criteria are quite good. But what you should actually do depends on a lot more things than the ones you wrote in your comment. It could be so irrelevant to only deserve a trace log, or so important to get a warning.

Also, you should have event logs you can look to make administrative decisions. That information surely fits into those, you will want to know about it when deciding to switch to another provider or renegotiate something.

> If the third party being down has a knock-on effect to your own system functionality / uptime, then it needs to be a warning or error, but you should also put in the backlog a ticket to de-couple your uptime from that third-party, be it retries, queues, or other mitigations ( alternate providers? ).

How do you define uptime? What if e.g. it's a social login / data linking and that provider is down? You could have multiple logins and your own e-mail and password, but you still might lose users because the provider is down. How do you log that? Or do you only put it as a metric?

You can't always easily replace providers.

Funny I ride a bike in Manhattan & BK (but only post COVID) and I very rarely experience cars going through reds. IME cars here respect traffic lights and stop signs. I try and count cars actually running a red ("speeding" through it) and it's rare, say 1/mo tops. Ymv I guess :)

They do not, though, give an owl's hoot about yielding to straight traffic when turning. I suspect NY drivers are on a big group chat encouraging each other to cut off cyclists and pedestrians, by turning into their lane whenever they see one, and promptly parking there for an hour.

And there's the "squeeze", and "crowding the box". Almost like no car here is truly allowed to ever really stop so they're always gently rolling, just a little, juuuuust a little, just, maybe, I know it's red but maybe just a lil squeeze into the intersection, maybe, squeeze, ...

I don't know how to explain it but if you've been here you'll recognize it I'm sure.

> So currently you'd need to have 4 images before it is a net win.

That's from an external storage perspective (fitting more images onto a floppy, which is, IIRC around 140 Kb).

You are typically only going to be loading one image at a time. So if you save an additional 100 bytes, using more than 100 bytes of extra code, it's not a win from a RAM point of view.

"high quality results". Yeah, sure. Then I wanted to check this high quality stuff by myself, it feels way worse than the overall experience in 2020. Or even 2024.

Go to docs, fast page load. Than blank, wait a full second, page loads again. This does not feel like high quality. You think it does because LLM go brrrrrrrr, never complains, says your smart. The resulting product is frustrating.

I'm not talking about one-ways, those are confusing in general. I'm talking about clearly marked off-ramps from freeways. In one situation the person had to drive over a fairly large bump in the median just to enter the wrong side of the freeway; again many signs to prevent such a thing and they still ended up in that predicament. Sometimes miles down the freeway before a cop pulls them over. It's terrifying.

I saw another one where the car tried to turn right into an off-ramp with a line of cars waiting at the light. Like wtf, do you not see the wall of cars and headlights in front of you? Where are you going?!

I think it's lawlessness overall. For instance, consider San Fransisco traffic citations. Went from around 11k in 2014-2015 steadily down and then fell off a cliff during covid but never recovered (around 1k in 2023).

I remember the sad story of Eric Garner who was killed in 2014 while being arrested for selling loose cigarettes in Staten Island. Today, at least in NYC, you see people parked out in front of the same corner every day selling weed and loose cigarettes. Same people, out in the open. I'm pretty sure that's not a sanctioned dispensary.

Just shows how much things can change in ten years. For whatever reason, police and prosecutors just gave up in enforcing any kind of laws. Seems like an overreaction to whatever problems we had with criminal justice

The numbers do appear quite staggering. It can't just be the dead drivers - there must be similar numbers of stoned drivers who are causing accidents, maybe killing others, while surviving themselves.

As far as driving goes, any amount of drugs or alchohol is going to reduce reactions times, in addition to any impaired judgement or ability to control the vehicle. Even a couple of 1/10ths of a second in increased reaction time is enough to make the difference between braking in time and hitting another car or pedestrian/etc.

Below is a comprehensive list of geoengineering-related patents, compiled to the best of my knowledge. Based on the language and scope of several of these patents, their stated purposes do not appear to be inherently human-friendly in any form as the language escalates from weather influence to planetary irradiation, artificial plasmas, relativistic particles, atmospheric weapons-scale energy systems, and even the generation of destructive weather events.

https://gist.github.com/pupdogg/4e796ed1bb0d24338a3f6523e404...

Examples:

1. System and Method for Irradiation of Planet Surface Areas 2. Method and Apparatus for Altering a Region in the Earth’s Atmosphere, Ionosphere, and/or Magnetosphere 3. Broadcast Dissemination of Trace Quantities of Biologically Active Chemicals 4. Method and Apparatus for Creating an Artificial Electron Cyclotron Heating Region of Plasma 5.

The most galling and pervasive offense, though, is TEXTING. The rampant texting while driving is killing pedestrians (and other drivers), leading to oft-cited statistics about the failure of "Vision Zero" and the increase in pedestrian deaths. Not to mention the millions of hours stolen from us all by people BLOCKING TRAFFIC while texting.

We should not tolerate the ignorant and ineffectual response from lawmakers on this issue. Year after year, they refuse to do the right thing: make texting a DUI-level offense, with the same penalties. You could even argue that texting while driving is worse than DUI: Drunk people suffer from impaired judgment; sober people texting have decided to endanger and steal from everyone else while in full command of their faculties. It's despicable.

Well, yes. They control ISPs and exit nodes, therefore they can correlate entries into and exits out of the Tor network, narrowing down candidate lists until only one user remains. Essentially a nation scale version of the Harvard bomb threat correlation:

As noted in the article, it wasn't the failure of Tor that led to arrest, it was poor OPSEC. Failure to cover, failure to conceal and failure to compartment.

It’s not controversial; you just want something different. I want the opposite: I want to know why/how it fails; counting how often it does is secondary. I want a log that says "I sent this payload to this API and I got this error in return", so that later I can debug if my payload was problematic, and/or show it to the third party if they need it.

I'm seeing the EU being singled out as unreasonable for avoiding the risk represented by buying their whole infrastructure from companies with deep and blatant ties to CCP's armed forces.

We actually have a full page on the methodology we used. We did over 20 experiments on the best way to digest this dataset and ended up settling on just using llms to review each interview in-depth. This helped us unlock some insights that would only be available if we paid someone to actually sit down and read every single interview. All other nlp approaches we used, like topic modeling, tfidf, and the roaring 2010s wordcloud,s were just too boring to even warrant a write-up. We tried bringing up as many raw excerpts to light as they make our point that much clearer. People are not simply "happy" about ai as Anthropic would have us believe, they are torn by it. It gives them a deep sense of angst and make them question the authenticity of their very existence.

I built an XSL stylesheet for Nmap that turns XML output into a clean, interactive HTML report.

The motivation came from penetration testing work where Nmap results are extremely useful during an engagement, but after delivery they often sit in a folder and are hard for others to read or explore. I wanted something that preserved the raw data while making it easier to understand and navigate.

The report focuses on readability and workflow rather than scoring or conclusions. It supports filtering by host and port, organizes service and script output so it stays compact, and keeps everything client side with no dependencies beyond the browser.

This is a personal project and still evolving. I’m sharing it in case it’s useful to others, and I’d really appreciate feedback on the approach or ideas for improvement.

It really depends on the third party service.

For service A, a 500 error may be common and you just need to try again, and a descriptive 400 error indicates the original request was actually handled. In these cases I'd log as a warning.

For service B, a 500 error may indicate the whole API is down, in which case I'd log a warning and not try any more requests for 5 minutes.

For service C, a 500 error may be an anomaly and treat it as hard error and log as error.

But what I also see frequently is people trying to do the impossible and idealistic things because they read somewhere that something should mean X, when things are never so clearly cut, so either it is not such a simplistic issue and should be understood as not such a simple issue, or there might be a better more practical definition for it. We should first start from what are we using Logs for. Are we using those for debugging, or so we get alerted or both?

If for debugging, the levels seem relevant in the sense of how quickly we are able to use that information to understand what is going wrong. Out of potential sea of logs we want to see first what were the most likely culprits for something causing something to go wrong. So the higher the log level, the higher likelihood of this event causing something to go wrong.

If for alerting, they should reflect on how bad is this particular thing happening for the business and would help us to set a threshold for when we page or have to react to something.

> In a review of 246 deceased drivers, 41.9% tested positive for active THC in their blood, with an average level of 30.7 ng/mL — far exceeding most state impairment limits.

That could mean they all had levels far exceeding most state impairment limits, but it also could mean most of them had trace levels, while a few had levels way above 30.7 ng/mL. So, it says fairly little.

Also (FTA) “Researchers analyzed coroner records from Montgomery County in Ohio from January 2019 to September 2024, focusing on 246 deceased drivers who were tested for THC following a fatal crash”. That means there could be selection bias at play.

Finally, no mention is made on the levels of THC in the general population of of those driving cars. Both _could_ be equal or even higher.

I’m not sure one should blame (only) the researchers for these statements, though. Chances are they didn’t intend to find out whether THC use is a major cause of vehicle crashes, but only in whether legalizing THC use changed those numbers, and someone managed to get some more juicy quotes from them.

We had some fun requesting key for accessing nist time servers. the process is (quoted from website)

NIST currently offers this service free of charge. We require written requests to arrive by U.S. mail or fax containing:

Your organization’s name, physical address, fax number (if desired as a reply method).

One or more point-of-contact personnel or system operators authorized to receive key data and other correspondence: names, phone numbers, email addresses. Up to four static IPv4 network addresses under the user’s control which will be allowed to use the unique key. By special arrangement, additional addresses or address ranges may be requested.

Desired hash function (“key type”). NIST currently supports MD5, SHA1, SHA256, and HMAC-SHA256. Please list any limitations your client software places on key values, if known: maximum length, characters used, or whether hexadecimal key representations are required. If you prefer, please share details about your client software or NTP appliance so we can anticipate key format issues. Desired method for NIST’s reply: U.S. mail, fax, or a secure download service operated by Department of Commerce.

NIST will not use email for sending key data.

ps. there actually seems to be improvement over what they had year ago. they added "secure download service". and previously they had message that nobody assigned to actively monitor mailbox so if you didn't get key, please email us so we will check it

most people who get put in jail/prison for drugs do not get a "taste" of how horrible it is and get years right off the bat for first offense

that's why I proposed five steps starting with warning, weekend, then week in jail

if you spend a weekend in jail and don't change your behavior from doing something wildly dangerous yet absolutely not addicting, well then proceed to a year in prison

note I am not saying put people in prison simply for smoking dope, it's not legal here but there are no serious penalties if caught

I don't care what people do in their homes

You drive on the road stoned when I am riding my bike or running and put my life in danger, you definitely deserve some time to think about it behind bars

I've been "grazed" on the road many time over the years, I have no idea if people are drunk or stoned or just looking at their phones but I am okay with my five step idea for ALL of those cases, but they will never be caught anyway until they murder someone and then it's too late

Its usually drivers license transfers from countries where small bribes can "buy" you a license? https://wise.com/us/blog/transfer-international-driver-licen...

The worst offenders are usually the older generations of countries where driving en mass is a recent thing. The old red guard uncles and aunties regularly run red lights cause who gives a damn about the law when you experienced the rule of the mob throughout your formative years. So parents and grandparents of students would be my guess.
Show HN: Cerberus – Real-time network monitor with eBPF
by zrouga | 2025-12-20 18:13:50+00:00
Hi HN! I'm Mo, a platform engineer at Deltaflare working on critical infrastructure protection.

I built Cerberus because traditional packet capture tools (tcpdump, Wireshark) have too much overhead for production CNI environments. eBPF lets us filter and classify packets at the kernel level with near-zero performance impact.

Some interesting challenges: - eBPF verifier is strict - every memory access needs bounds checking - Limited to 32 bytes of L7 payload (tradeoff between inspection depth and overhead) - TC vs XDP decision (chose TC for compatibility)

Looking for contributors, especially on: - Redis backend for distributed deployments - Prometheus metrics export - Anomaly detection

Happy to answer questions!
