redm··on Why 56k is the fastest dial up modem speed
This brings back a lot of memories, but I think what I lament the most is that this was really the end of American soup-to-nuts engineering in telecom. At the end of the 56k production and the start of G.Lite DSL, all this engineering started going to China to save money. Long gone are the days of Radio Shack and companies EE's designing, prototyping, testing, and manufacturing electronics. Sad.
redm··on Tunnel Vision: CloudflareD AbuseD in the Wild
Thank you for your response. Since I have your ear, I'll provide some direct feedback.

"We definitely care about abuse generated by Workers."

That may be the case internally but it's not as evident through support. I base this on their ability to answer security-related questions, diagnose odd behavior, or mitigate problems. FYI, we are paying for your highest tier of support.

"it should be treated as if they were running their bot on any other cloud provider and making requests across the internet."

Part of this is how Site Analytics and WAF analytics represent worker data (or don't). Even though the worker modifies the contents, the IP is passed through as the end-user IP (at least the way we use them). These analytics systems need to do a better job of identifying anything worker or tunnels related. If this were being done through AWS it would be evident. We can use various mechanisms to mitigate this, but I wanted to clarify why abuse through Workers is different for our implementation.

Also, the process to block non-zone workers was undocumented, and it took a couple of weeks for someone to dig it up and only after several trials and errors. Support wasn't sure it would work, and there was no other documentation (at the time).

We have yet to get an answer about the high volume of tunnel requests from specific goes.

Combine this with the opaque stack you have that causes odd situations. For example, I added a worker that automatically retries 500 errors from the origin. Simple enough. This breaks Zero Trust, though, and causes a redirect loop. There may be documentation somewhere, but there isn't a good breakdown of how Zero Trust fits into a customer-defined worker, and a redirect loop is undoubtedly a poor failure mode.

There is a world of difference between the information you have and may provide as the Technical Lead of Workers, and what I'm getting via support or raw documentation.

I could provide you more information offline if you want.

Edit: Let me just add the other recent thread [1] regarding redirect loops in verification is par for the course. We had the same issue and tried for weeks for progress or resolution. The issue was never resolved, nor could we get information on why the failure mode was so poor, etc. That ambivalence adds up to expecting general ambivalence or inability to make meaningful progress. At some point, you say to yourself, "Why waste my time talking to support and putting in much effort and getting the run-around."

redm··on Tunnel Vision: CloudflareD AbuseD in the Wild
I find that more and more CloudFlare is so ubiquitous that we have to use CloudFlare tools to protect ourselves from other people attacking us via CloudFlare. Here's an example of a rule we had to put in place to block people using CloudFlare workers to scrape pages and bypass security. CloudFlare doesn't seem to care about this kind of abuse (or maybe they do but aren't talking about it publicly).

(!cf.bot_management.verified_bot) and (cf.bot_management.score lt 10 ) and len(cf.worker.upstream_zone) gt 0 and not cf.worker.upstream_zone in {"<zone>"} and (not ip.geoip.asnum eq <exception as>)

redm··on Semiconducting Transport in LK99 reproduction attempt
Seems there is new support that its legit!

https://twitter.com/Andercot/status/1686215574177841152

National Lab (LBNL) results support LK-99 as a room-temperature ambient-pressure superconductor.

Simulations published 1 hour ago on arxiv support LK-99 as the holy grail of modern material science and applied physics.

redm··on The World Bakes Under Extreme Heat
To have dramatic change, you have to either have a technological breakthrough or get the entire planet to agree to make a consistent change. It's a tough sell for many geo-political reasons.

Right or wrong, it's hard for developed economies to destroy their economies while China (and others) are rapidly making the problem worse. [1] Progress is being made through:

"The Climate Action Tracker says that between 2015 and 2022 China's greenhouse gas emissions increased nearly 12%, while U.S. emissions declined some 5%. China's methane emissions rose about 3% from 2015 to 2021, the latest year with good data, while the U.S. cut them by 5%." [1]

redm··on HTTP vs. WebSockets: Which one is the fastest for Postgres queries at the edge?
@raoufchebri & @nikita, What about comparisons to CloudFlare Workers using Workers Sock API to connect to PG? [1] I know CloudFlare workers support Neon directly through API so how does that compare to the alternative PG implementations?

redm··on GitHub Private Repos Considered Private-­Ish
I see a lot of deserved distrust of MS, but I thought GitHub was a operated as a separate unit under Microsoft? [1] I expected that Co-Pilot was an initiative of that leadership team and training the LLM is what's likely reading certain repositories?

On a side note, I'm trying to imagine what "sensitive" code would be read, incorporated into an LLM such as Co-pilot, and somehow have any meaningful impact to me once incorporated?

redm··on KeyDB – A Multithreaded Fork of Redis
To counter what the other active business said, we tried using KeyDB for about 6 months and every fear you concern you stated came true. Numerous outages, obscure bugs, etc. Its not that the devs aren’t good, its just a complex problem and they went wide with a variety of enhancements. We changed client architecture to work better with tradition Redis. Combined with with recent Redis updates, its rock solid and back to being an after-thought rather than a pain point. Its only worth the high price if it solves problems without creating worse ones. I wish those guys luck but I wont try it again anytime soon.

* its been around 2 years since our last use as a paying customer. YMMV.

redm··on Blizzard developers say return-to-office policy 'cost us some amazing people'
I don't think this is a one-size fits all.

I've been WFM for 7 years now. I don't think RTO is a bad thing, but its all situational. How silo'd are projects and how much inter-team coordination do you need? How long is your commute? What kind of person are you (some people just work better in office environments)? Do you need physical access to equipment? The list goes on.

Being fully remote has allowed flexibility for team members to relocate without being forced to leave and thats been the biggest advantage. Going from a FTO to WFO or RTO is a big transition that requires re-defining workflows and communication mechanisms. Products like Zoom and Slack have made that far easier, but the bigger the organization, the harder the transition.

Personally, I miss having an office. I've lost human connection by being isolated at home that isn't replaced with normal social interactions. Maybe thats just older men not making time, but office space traditionally filled that role for me.

It’s finally that moment when something from your “youth” has become a historical curiosity.
redm··on Binance to suspend US dollar bank transfers
"From looking around the internet I am starting to believe I might be the only person holding crypto strictly because I just happen to think it's neat."

I'm holding crypto because I think it's neat, but I'm also holding it because there's little I can do with it... i.e., lack of general utility, yet.

redm··on Deepmind is working on a rival to ChatGPT
If there is a threat to Google, it's not that ChatGPT beats them on technology, even if it does. What changes Google is a competitor in search, Microsoft, that integrates natural language into a search engine without as much concern for showing ads or linking users through to websites. It may not kill Google, and Google may become more profitable, but it will be fundamentally different.
redm··on Netflix has created a self-fulfilling cancelation loop with its new shows
The worst part of this is the statement that 1899 was canceled. I just finished it and was looking forward to the second season. I guess there's no way in Netflix to know if a show is ever coming back.. Will there ever be another Black Mirror season.. who knows..
redm··on Ok, Cloudflare I am leaving
This is a problem of CloudFlare's own making. They provided a lot of services for "free" to gain scale and market share. Now they are a public company, and things are changing. A pro plan does not give you unlimited CDN data transfer, but I've heard from people enough times, "Just do it on Cloudflare for free", and that perception is CloudFlare's making. When you get to the Enterprise tier, CloudFlare works just like a traditional CDN in terms of metered usage and billing.

* I've been using various CDN's since the 90's, and I'm currently a Cloudflare Enterprise customer. However, Cloudflare, not without its faults, is still the best option out there.

redm··on EU adopts global minimum 15% tax on big business
It's where the profits are, not where the cost centers are. If the customers are in France, the profits are in France.
redm··on Show HN: 0xFast – Faster Web3 APIs
Congratulations on the launch! Looking forward to more middleware to enable the app ecosystem to develop more rapidly.

"We build and run our own servers. In datacenters."

Is this a selling point today? Suddenly their background in on-prem architecture, operations, security, and network management becomes very important.

redm··on PayPal phishing scam uses invoices sent via PayPal
This problem is similar to problem's I've had as well. Scammers/Spammers exploit services and tools in such ways that its difficult to prevent without manual review. Just like in Field of Dreams, If you build it, they will come.. The best advice is Buyer (or reader) Beware.
redm··on How Bungie identified a mass sender of fake DMCA notices
This is highly overlooked “The company tried to subpoena Google using the DMCA but the chosen mechanism only allowed Bungie to identify an alleged copyright infringer, not the sender of allegedly abusive DMCA notices.”

We have been the recipient of many invalid notices to Google. Google publishes the details via Lumen but makes it impossible to reasonably analyze the data. 1) They hide the sender info. 2) They make you validate, via email, for EACH DMCA you want to view. In other words, they claim transparency, but practical use isn't possible. They also don’t publish DMCA’s against sites like YouTube.

redm··on Ask HN: Cloudflare broke my domain's DNSSEC making it unreachable since 4 days
Enterprise plans no longer come with "premium" support either, you are looking at 20% over contract value to get a similar level of previously included support and an SLA. To be fair, CloudFlare provides a lot of services for free and $20 premium plan with upgraded support seems like a pretty good deal!
redm··on OVHcloud fire: SBG2 data center had no extinguisher, no power cut-out
I've spent a lot of time in US Data-centers, and I can't remember seeing one without an EOD. I've even seen them pressed a few times accidentally when people exiting the floor thought they were "exit" buttons.

Are they talking about the lack of an EOD or something more fundamental to the power system? It almost seems like you need something external to the facility in case of a fire where it's unsafe to enter the building.

redm··on Subaru, Kia shut off some car features rather than adhere to 'right to repair'
Unless I'm missing something, you have your own API, SDK, Service Fees/Pricing, and overall business. Certainly it's good for you if people standardize on your platform, but I'm not sure thats realistic. It's also not exactly the same as an open standard that can be applied globally. i.e. an extension of ODB-II access to the CAN bus I guess? That standard will probably need to come from the manufacturers themselves.
redm··on Slackware 15.0
I used Slackware for years in the 90's before moving to FreeBSD. I honestly thought the project was dead and moved to Arch. Sadly, I'm not coming back, but I keep fond memories.
redm··on Austrian DPA Ruling Against Google Paves the Way to EU-Based Cloud Services
This could go a few ways. First, I'm sure Google will fight this and the fight will go on for some time. If they loose, Google could build EU data-centers and try to be GDPR compliant, which seems the most likely outcome. They could also pull out of the market, which seems less likely. If they pull out, I'm not sure that would be good for the EU market. People are suggesting that EU entities will spring up to fill the void, and thats probably true, but those services will almost certainly lag the benefits of the big US clouds. That may put EU entities at a competitive disadvantage.
redm··on We're migrating many of our servers from Linux to FreeBSD
I used FreeBSD for many years (on servers) between 2001-2009. I also used it as a personal machine in the 90's. We used it for stability, at which it did well.The real problem was that everything was moving to Linux. The Linux kernel and community kept up with with bleeding edge hardware or software. Stability of Linux continued to improve and most people stopped compiling custom kernels anyway. I used to compile most user-space software too, and almost never do now. That largely negated the FreeBSD benefits.

redm··on 1906 San Francisco Earthquake and Fire

redm··on Tell HN: AWS appears to be down again
Some datacenter failures aren't related to redundancy. Some examples: 1) transfer switch failure where you can't switch over to backup generators and the UPS runs out, 2) someone accidentally hits the EOD, 3) maintenance work makes a mistake such as turning off the wrong circuits, 4) cooling doesn't switch over fully to backups and while your systems have power, its too hot to run. The list can go on and on.

I'm not sure why this is a big deal though, this is why Amazon has multiple AZ's. If your in one AZ, you take your chances.

redm··on Debunking Cloudflare’s recent performance tests
I think statistics like these tests are easy to sway in your favor, hence why Fastly is responding. Its not clear that Fastly didn't do the same thing, but a good ole' CDN rivalry does make for a good read. Someone get more mud to sling.
redm··on Disney’s Influence on U.S. Copyright Law
I don't see why IP such as Mickey Mouse should be treated any differently than patented IP. 20 years is a fairly length time to have a monopoly on your creation before it becomes public domain.
