They didn't. Sounds like they gave the robot an AWS key from an account that was already linked to a credit card.

The robot decided to spin up an expensive setup prior to getting access, so the setup was sitting there costing money whilst it did nothing.

If it had designed the setup but not spun it up until it had authorisation to join the network then it would have been much less costly an exercise.

It all comes down to where the boundary for data access is implemented, and how strictly.

If your webapp has unfettered database access then don't be surprised if it is hacked and someone can do `select * from users` and then posts that dump somewhere.

The attack surface changes if your webapp can only do a REST call to pull a single user record at a time. That way you can put some auditing in, you can put rate limiting in to detect that, etc.

Obviously the user record REST api endpoint is still vulnerable, but it's a much smaller attack surface, easier to audit, and can be monitored a lot more closely.

Yes, ultimately, there will still be a set of vulnerable humans that have access to the database servers themselves and they can always walk out of the place with an SD card hidden in a Rubik's cube but there has to be an element of trust somewhere.

The problem is that too many people put that trust boundary way too far out into the big bad Internet. Or don't even consider it at all and just rely on the fact that other targets are more appealing.

Plus addressing (or movable periods in gmail addresses, etc) is increasingly pointless for a whole host of reasons.

It may keep out the bottom x% of spammers/hackers but it doesn't do much for the increasingly sophisticated scams that are appearing.

If the bit before the + ends up in your inbox anyway then it'll just get stripped off and used. Spammers seeing this kind of thing across several breach dumps:

bob+trello@example.com, bob+spotify@example.com, bob+chase@example.com

and will leverage that to target spam at you for other sites, or just email bob@example.com as there's a good chance that'll get through.

Years ago I did a test with my own domain where I created who unique aliases with plus addresses, e.g. steve.smith+iawer@example.com, bob.jones+wpoqe@example.com

It didn't take long for emails to start arriving to steve.smith@example.com and bob.jones@example.com even though that email address had never been used anywhere ever before.

As others have said, you're better off just creating unique emails with `pwgen -s 16` such as wmR5pNhGI8yidU7N@example.com and storing that in your password manager alongside a similarly random password. (Yes, this is roughly what those unique email address services provide.)

Also many services/sites/providers simply assume the username is immutable. $DEITY forbid you might have to change your email address at some point in the future.

Can confirm it's free. I tried it based on the GP comment. There are various ways to prove it is your domain: token sent to one of a small number of email addresses like {admin,security,webmaster}@, DNS TXT record, place a small file in the root of the website, etc.

The only extra bits I saw for the other emails on my domain was a plus address I'd used for last.fm which had been leaked. None of the other emails (wife, kid, family, etc) appear in any breach.

I'm slowly moving away from using my own personal domain as it's becoming an ever increasing burden. I'm also concerned that my wife/kid will be left with something they may not have access to, or would stop working at some point, if I suddenly dropped dead.

Someone in the house pressed the button to update the printer (Brother DCP-L3550CDW) firmware and the CSV page that was the basis for an existing Prometheus exporter (drum/toner lifespan, page counts, etc) stopped being a thing. Instead there was an HTML page with all of the information buried in various divs/etc.

I'd planned on writing something myself to parse the HTML and write a suitable exporter but I thought I'd give Claude a chance.

In a sandboxed VM I gave Claude a single static HTML file of the status page from the printer, also in the directory was the equivalent of "hello world" in Go, literally just the minimum needed to do `fmt.Printf("OK\n")`. The directory was called `brother-exporter`. That was it. No other instructions or information. I hadn't told it what it needed to write. I hadn't said what it should do. I hand't told it what language it was supposed to use.

Just by doing a `/init` in that directory Claude decided that it needed to write a Prometheus exporter in Go that would fetch and parse the HTML file from a printer (defaulting to 192.168.1.1) and then present the associated metrics in a way that they could be scraped by Prometheus.

It did this flawlessly in about 10 minutes.

I could have done it in several hours but this was definitely an "oh shit" moment for me. I think the biggest thing was the fact that it guess/assumed so much (correctly) from so little information in the beginning.

10g Upgrade 2 months ago

For my own 10G homelab network I jumped the gun and got a couple of Intel X540-T1 cards for my two servers and balked at the cost of the RJ45-SFP+ transceivers (Unifi's version is ~USD60). (I'm sure there are cheaper options for the "not hot" flavour transceivers but I didn't want to have to gamble again.)

In the end I just replaced each X540-T1 with a X520-DA2 which are pretty much the same price on eBay (under USD20) and then I can just use a DAC that's a fraction of the cost of the RJ45-SFP+ transceivers.

Some companies are purposely obtuse about it.

My wife is trying to sort something with a famous Irish airline who are well known for messing people around. She has LPA/POA for her mother but rather than the airline accepting the VCode (this is the UK) the airline are requesting to see the original POA certificate which is just ridiculous. They seem to be moving a little quicker now there is solicitor involved.

Given how much back and forth there has been it's probably cost the airline more than just refunding the amount at the first request. We'll keep going to prove a point.

Going for a cup of coffee means physical walk. Detaching from focussed mode means your mind gets in diffused mode. This is where/when creativity ensues.

Sure, but I want to choose when I do it, not have it forced upon me.

75 mbit up is pretty good compared to DSL (I bet it is cable)

It is FTTP not DSL or cable. BT Fibre 500 in the UK. Almost all of the deals through the legacy/monopoly provider (BT/Openreach) are asymmetric like this.

The 2500/2500 at the new property is a different provider that has their own network and so isn't tied into reselling Openreach's GPON infra.

The "Sasha" section brought back a load of memories from my childhood. As an Alex growing up in Western Europe with no connections to anything East it was just my Russophile father that used to call me Sandy or Sasha some of the time.

Edwardian houses in the UK rarely have that level of access. No basement at all and I can't lift the carpets and floorboards to get to where I might be able to pass things through/around. No AC ducts. No coax to be able to use MoCA either.

But, yes, that video is exactly the kind of thing I had in mind for the bend insensitive fibre.

It all depends how I set things up (and I can't tell that until I've had more access to the property). The ONT and the rack with the USW-Aggregation switch are 10 yards apart, in terms of absolute distance, but probably 20 yards if you follow the walls/skirting-boards/etc.

The FTTP is presented as 2.5GbE Ethernet (apparently) so I can either:

a) put my Unifi Express 7 next to the ONT and then need a fibre run (something like https://uk.store.ui.com/uk/en/category/accessories-modules-f...) from the SFP+ port on the Express 7 to the USW-Aggregation in the rack.

However this will be sub-optimal in terms of Wifi and I'll probably need extra APs to cover all three floors and out into the back yard.

b) put my Unifi Express 7 in the hallway in the middle of the house (which should give me full Wifi coverage with no extra APs). This would mean a short (2m) DAC to connect it to the USW-Aggregation nearby, and I can use a 20m long flat/flexible Cat-6 Ethernet cable to go between the ONT and the Unifi Express 7.

I had a big debate with myself whether to go Mikrotik or Unifi. Being EU based I really wanted to go Mikrotik but ended up with Unifi as I'd had more experience of it when helping out friends/neighbours.

Maybe my "last house" (i.e. the one we'll get to see us through to retirement and beyond) will be Mikrotik based. By then I'll probably want as little computing stuff as possible and will just sit in a comfy chair doing crosswords and sudoku with a pencil.

The limiting factor for me is that I'm renting so I can't put my own cabling in to the property. And with the new place there's no existing cabling, nor any conduits to run anything in, and chasing things into the walls/etc is going to be prohibited by the landlord or just too expensive if I'm only in this place for a year or two.

The spools of bend insensitive fibre are pretty cheap and very discreet so I'll probably have a couple of those running along skirting boards/etc in order to connect disparate areas of the house. (The ONT is ~15m away from where the majority of the equipment will live, that's the main bit I have to bridge.)

True, I don't really feel limited by my existing 500Mbps down, but knowing I'll be having 2500Mbps up/down soon means I want to have the infra to handle it.

Basing things on 2.5GbE would certainly have been cheaper but some things don't support it (they either do 1GbE or 10G SFP+) so settling on 10G where possible made more sense to me. My future ISP also has a 5Gbps up/down option, but even I can't justify that right now.

My wife and kid just want their phones/laptops to work, and to be able to stream stuff to watch, they don't care about the underlying speed.

Having a faster network may make some of my work related things run a bit quicker. A few times a day I'll need to pull something big down (either an ISO or a bunch of docker images) and that can take up to 2 minutes with 500Mbps down. Having those take a fifth of that time will make it seem less of a roadblock to doing work. 2 minutes meant I went and got a cup of coffee and often got more distracted, 30 seconds should keep me at my desk and focused on what I was doing. That's not a big enough reason to justify it on its own obviously.

I also want to do offsite backups with/for various family members, so something better than 75Mbps up is going to be a huge boost. Getting 1Gbps+ out will be huge (assuming whatever is at the other end can support that).

I don't do any kind of data hoarding, I think I've got something under 4TB of data that I actually care about, and most of that are family photos/videos.

Deep down it's mostly because I'm a networking geek so it's fun to play with some new kit and make blinkenlights.

Ha. I meant the rest of the equipment (USW-Aggregation, Unifi Pro Max 16, UNAS Pro, Unifi Express 7) was somewhere around half retail price.

I think I paid ~$15 for each X520-DA2 including postage.

I'm only planning on using one of the SFP+ ports on each of the cards, the dual port cards were just more common and cheaper on eBay.

The specs say they require PCIe v2.1 x8 lane.

My Proxmox server is quite old and has a Gigabyte GA-X79-UP4 mobo and has loads of spare PCI slots. One slot is taken up by a generic graphics card as the Mobo has no on-board graphics. (I think I went for this mobo because of the number of SATA ports, but it was over 10 years ago so not entirely sure.)

My general Linux server is newer and has an ASUS Prime H610M-A D4 mobo. Only two PCI slots (not used at the moment) and so the Intel X540-DA2 will use up the PCIe 4.0 x16 slot leaving just a PCIe 3.0 x1 slot. But that's fine as this machine is just a CPU (i7-13700), 64GB RAM and a 2TB NVMe. Sticking a good graphics card in it for GPU related fun had been on my list for years but I never got around to it, now the prices are just insane so I'll ignore that for now or something second hand falls into my lap.

I'm waiting for 3 DACs and a few other bits to arrive today to move closer to 10G networking at home. Moving house soon and the new place will have 2.5Gbps FTTP (both up and down) so I wanted to be prepared for that. Given my existing broadband is only 500/75Mbps FTTP I was fine with a 1GbE internal network and Wifi-6 meshing. I could have planned to move to 2.5GbE but it may have been a bottleneck at some point, so may as well push straight on to 10G.

I have a USW-Aggregation with 8 SFP+ ports arriving today too. Just have to install Intel X520-DA2 cards in two of my servers (Proxmox host and a general Linux server), and the NAS also has a 10G SFP+ port, and then connect it all up.

Most of it second hand from eBay for half the usual retail price.

This is almost as good as the classic HN "Putnam" comment: https://news.ycombinator.com/item?id=35079

Also the person is actually the CEO of Dropbox, the very person this thread is all about.

Some companies pay more if people are paged. It can create a perverse incentive not to fix problems or, in extreme cases, to watch things going wrong, waiting for the page, and then being ready to fix it straight away.

One team can't troubleshoot AND FIX every possible subsystem, so you just end up with lots (growing to hundreds) of people "on-call" anyway.

As others have said, follow-the-sun type models do exist, usually staffed by people in their normal working hours (EMEA, Americas, APAC) but this means you've still got to cover the weekend and public holidays (which there are a lot of when you factor in plenty of different countries).

Where you need a quick response you can have a core ops/noc team that looks at things with lower thresholds and shorter windows, and their job is to do the initial triage and then page the appropriate team earlier than they would have been alerted by their own alert thresholds/monitoring.

Actually clicking the button to change the status on a public status page is a whole different topic that becomes very political in certain companies.

Github measures/reports the SLA of the individual services.

The external page linked above goes the other extreme and considers it a bad status whenever any individual service is degraded.

In reality the majority of people only use 3 or 4 of the core services the majority of the time but since there's no "core services" SLA/uptime the usability of github for the majority of people is slightly obfuscated.

But many years ago I gave up Scrum completely in my teams. What’s more, over time I almost stopped coming across startups where Scrum is used in its classic form at all. Many distributed teams are gradually moving toward an async approach ...

It is my personal opinion that Scrum/Agile is just a rather dramatic/over-the-top system for fixing dysfunctional teams that have fallen into poor or absent communication anti-patterns.

(I also think the general trend towards async among distributed teams is that more people have gone through this and have picked up the "better" communication habits.)

After you've done it for a while you start to find that many of the individuals are talking to each other without the various contrivances.

Planning poker isn't really about project sizing, it's about surfacing issues that the team members might not find out about if they don't talk to each other. I've been on teams where someone has spent 2 months working on something only to find that someone else had 90% of the work done in a private branch.

After the third of fourth time during planning poker that someone is reminded that they need to consider the testing/docs aspect they start to factor that in without being prompted.

The daily standup is similar. "I'm going to frobnicate the foobar today" and someone will say "Ah, have you spoken to Alice in that other team as she did the same thing with Bob's team last week, she's got a load of scripts that should save you a load of time."

Retrospectives are about acknowledging people who did good work, what worked well within the team, and also raising the things that held people back. If you have a good team leader they should be wondering why on Earth this is the first time they're hearing about any of this stuff. (A bad team leader will continue to blunder on not learning anything and being blissfully unaware that they're missing the really big neon signs, or they'll find some other way to dismiss the concerns/findings.)

Eventually you may get to a point where there is very little face to face communication required because the team starts to use the async communication systems properly, they communicate freely between team members and also upwards. But this is often a precarious situation, it doesn't take much for the boat to be rocked, new people coming in, trusted people leaving, new projects, new directions, unrealistic deadlines, etc. Every so often it requires more communication than before to get things back on track.

Once you're over the "scrum/agile solves all" hill people tend to pick/choose what continues to add value, and they discard the rest. (For the teams I've worked on in the past it was the "don't interrupt or change course mid sprint" rule that worked best for us - so many times the urgency had disappeared once we had got to the end of the sprint and we'd been saved from ultimately unnecessary distractions.)

Back to the management style in the article, even though I could work somewhere with little or no regular verbal communication I know I would quickly find I absolutely despised it.

I've done long solo projects in the past with no real colleagues or technical leadership/reporting. I found it far less rewarding than being part of a team (although it was often more financially rewarding). I get that some people thrive on this kind of thing and I'm happy for them. Every so often I like to go deep on something but how long I can tolerate this for is becoming shorter and shorter as I get older. There's a big difference between going a full day or so in focus/flow mode to extending this for days/weeks/longer.

I used to seek out 1:1s with random people in the company. I'd join the "watercooler" video call a few times a week to just chat random stuff with random people. As for async comms, although we were all good at starting off with well thought out full initial message/question on Slack (not just a "hello" and then silence) many of these were better off resolved via a quick video call once it was clear that async wasn't the most efficient method. Pretending or hoping that everyone is so eloquent, clear and exact with their language that you can do everything async is just fantasy in my experience. If the question was raised in a channel (rather than a DM) then someone would go back and provide a brief summary so that anyone finding the initial conversation by search didn't just hit a "let's jump on a call" cliffhanger with no resolution. (Then the company grows big enough that Slack retention policies become a limiting factor.)

I've definitely worked with people who can work with little or no interaction but even in workplaces with a greater than average concentration of introverts and neuro-divergence such people (who can work like that) are in the great minority (again, IMHO). Most people work better with direct access to empathy, reassurance and even just someone to listen to them ranting. The trick is to find the right balance as too much communication can be stifling, but I'd rather be in that situation and working on dialing it back.

I think most people constantly try to adapt their setups based on every changing work/life requirements, plus also phases/trends of "lots of monitors" <-> "single big monitor", etc. There are random attempts to declutter or go minimalist. Less is more. But then more stuff comes (and maybe goes). Seasons bring extra lighting, a desk fan, a heater, etc.

I've worked in a variety of setups in both offices and at home.

Working for a startup I spent 18 months with 3 of us crammed into 2 normal desk widths. I think I had not much more than 60cm of desk for the whole of this time. The front portion of my desk was the keyboard and mouse and the back part of the desk was the desktop PC with monitor on top of it and a desk phone (2-4 hours a day spent on the phone to customers) to the right of that. Just enough space for a water bottle and/or coffee mug between the mouse and desk phone. I was disproportionately happy for the times when one or both of my colleagues either side of me went on PTO.

At some points I had a 90 minute commute (each way) by train and used that time to bash away at things on a Linux laptop. No chance of network connectivity on the move, this was the late 90s, the huge laptop (Toshiba Satellite things that were 50mm thick) could barely last the 90 minutes anyway. You made sure it was fully charged and that you'd downloaded everything you needed for the journey before you left home or the office. And you still took a book (or pen/paper) for the inevitable times you hadn't.

Other than this necessity it takes a lot for me to get into any kind of a flow if I'm not sat at a desk. I can't take my laptop and just sit on the sofa and do things, it just doesn't feel like "work". I'm hoping to get better at this though as I do envy people who are happy doing this.

For 18 months I worked in a classic cube farm in a corporate HQ in the US. Reasonably big cube with 6' high walls and U-shaped desk, so there was an easy way to have different zones for "laptop work", "paper work", and "other" (usually lunch _al desko_). It was nice having a little locker for hanging coats/etc, and a place for the internal/external mail to be delivered. The nearest window was probably 30 yards away from me and even then you really couldn't tell whether it was night or day. Sometimes I wasn't sure whether I was alone on our part of the floor or whether the other ~150 people were there.

My favourite office setup was back in the UK with a big L-shaped desk in an area with lots of glass partitions and windows. There were about 5 of us in the space that would usually be occupied by about 40 if they were trying to pack them in, but we were left to get on with things. It was deathly quiet too, which I loved. I had a view across South London and could see plenty of sky, buildings, trees and people.

My home offices have been OK but far from perfect. Too warm in the summer months given no aircon (I've got the sun beating down on my back right now), never too cold though. But never enough space. They've also always been a work in progress and never "right, that's all sorted" but I hope to get a bit closer to that with the next move.

I reckon I'll get it right just before I retire.

I have GEB, TAoCP, Stevens, Crandall/Pomerance, Tannenbaum, Aho/Sethi/Ullman, Schneier, K&R and a bunch of other books on my shelves next to me. About 1000mm worth in total but I could probably trim it down to about 600mm if I stripped out the random extras related to old projects (Rails/JavaScript/Mysql/etc) or stuff you just don't need a book about (Git).

Putting them anywhere else in the house would either be more "showoff" or just less practical. It's true that I rarely ever pick them up but the few times I do I'm glad they're right next to my work desk.

I'm moving house soon. Still yet to work out the home office plans.

There's an area on the middle floor landing that could make an ideal little desk area.

It's something like 150cm wide (my existing desk is 140cm) and deep enough for my 70cm deep desk and existing chair. There is a window directly ahead. The only problem is isolation, there's no door to close things off (noise or distractions), but I may be able to make do with a heavy curtain and my existing noise cancelling headphones.

This would mean that the spare bedroom (which would usually be the home office) could be an alternative home office for myself or my wife, and more of a spare bedroom for visitors. Right now our existing spare bedroom is a dedicated office.

I'm going to use the article as inspiration for the spare bedroom and not just putting the desk up against the wall as I would usually do, but the planning depends on what size bed we can get in this room as well as a desk.

Well, you can approximate it with crude measurements.

Using the photo under the "Rethinking the desk" heading we see an Apple Studio monitor on one side.

On my monitor/browser/resolution/etc the desk is 157mm wide in that image and the monitor is 48mm wide.

The Apple specs say that monitor is 623mm wide.

So that would make the desk roughly 623*157/48 = 2037mm long.

That makes sense, his computer setup is relatively small compared to the analog side.

I have a dim memory that one of my A-Level physics teachers (David Massey) was credited as a consultant on the Newtonian physics in F:E2.

The game came out at the start of my upper-sixth year so it often came up during his classes.
