Late 90’s I had a ~90 minute commute for a while (50min train with seat, 20min London Underground seat mostly, 15min train crammed, 10min walk).
The longer train I would use my laptop, same with the 20min underground section on the journey in (going home no chance), but for the packed train and the walk I listened to music (I still have my Diamond Rio PMP300, no idea if it still works, just remember downsampling music to 32kbps to get more on a memory card, quality was less important than quantity - I must have listened to David Gray’s album _White Ladder_ many hundreds of times).
Toshiba laptops (Satellite? I think they were before the Tecras), heavy and the battery life wasn’t much more than 90 minutes but it was just enough. Dual booting Windows and Linux. (Linux for dev work on the go…)
Obviously no mobile connectivity back then, I had to have a plan for what I was going to work on and that also involved backup plans if I ran into a blocker on the primary. Same for the way home.
A bit later I could get GPRS data rates via Infra-Red to my mobile and that just felt like magic.
I found the times I couldn’t be on my laptop (walking or on the packed train) were great for thinking problems through and often had to stop to scribble down thoughts/ideas/solutions in a notebook that I kept in the laptop bag.
Wrote so much useful code in that 18 months without the distractions of the Internet or emails or whatever.
Now I somehow find I have less time despite having virtually no commute. Technology has vastly increased the number of distractions and I have let myself succumb to them. Where I had no real choice in what music I listened to now I have too much choice. There’s always one last thing to check before I get on with a bit of work. Sometimes I wish for simpler times.
A friend once asked me to do some pen-testing on a machine he was running on his home network. He said I'd need to come round to his house to do this as he didn't want to provide access to the machine via the Internet. Fair enough.
When he opened his front door the conversation went something like this:
Him: "Ah hello, thanks for coming round to do this. It should be fun, come in and we can get started."
Me: "OK, but I'm already done."
Him: "What?"
Me: "I'm done. I've already got root on the machine and I left a little text file in root's home directory as proof."
Him: "What? But ... what? Wifi?"
Me: "Nope. Let me in and I'll explain how."
The short story is he had an PoE IP-based intercom system on his front gate. I remembered this from when he was going on about his plans for his home network setup and how amazing PoE was and how he was going to have several cameras etc. I also remember seeing the purple network cable sticking out of the gate pillar whilst the renovation work was being done and the intercom hadn't yet been installed.
I'd arrived 45 minutes early, unscrewed the faceplate of the intercom system and, with a bit of wiggling, I got access to a lovely Cat-5 ethernet jack. Plugging that into my laptop I was able to see his entire home network, the port for the intercom was obviously not on its own VLAN. Finding and rooting the target machine was a different matter but those details are not relevant to this story.
I suppose I got lucky. He could have put the IoT devices on separate VLANs. He could have had some alerting setup so that he'd be notified that the intercom system had suddenly gone offline. He could have limited access to the important internal machines to a known subset of IPs/ports/networks.
He learned about all of the above mitigations that day.
I've always wondered just how many people have exposed their own internal network in a similar way when trying to improve their external security (well, deterrent, not really security) but configuring it poorly.
Now we need to get an enterprise grade switch - doubt Cisco would add macsec into SOHO gear. Along with enterprise grade intercoms, cameras, doorbells...
And beloved by many Unifi is out of question - they still can't bake IPv6 support.
So looks like it's feasible but the cost wouldn't be good.
i well familiar with macsec. we use it between datacenters and for aws directlink. it de-facto standard for this kind of stuff. i even worked on hardware that provided macsec support
a couple of years ago I tried to use it inside datacenter during fedramp implementation. it crashed and burned for a couple of reasons:
- linux wpa_supplicant was crashing during session establishment
- switch had a limit on number of macsec session per port
They still engage, possibly even more so, with the topic if it's setup and structured the right way. (It's all too easy for lazy teachers/schools to just shove work onto a laptop for the kids to do and then pay little attention, but this was also definitely true back in the days of work from books or sheets of paper.)
My 15 year old can touch type(*) at about 60wpm, knows how to browse the Internet and drive a search engine effectively, can create reasonable presentations using Powerpoint or equivalent, can create nicely formatted docs, is comfortable with spreadsheets, not be fazed by online forms or similar, has a basic understanding of cyber-security/safety, password security and password reuse, spotting scams, etc.
All of these are useful skills that my parents in their 70s struggle with.
Having a phone means they're able to keep in touch with their friends far more effectively than I was when I was that age. They can keep in touch with us (parents) much more easily. They can see how much money they have as they've got a banking app on their phone. They can check the weather themselves. They can check the train and bus times themselves.
I trust my kid to use the phone (and laptop) responsibly. In return they know that I will occasionally ask to check what they're doing just to make sure they're safe. I don't want to have to police it.
Back to the school bit, they could be doing Maths questions from a piece of paper or in a book, which they do do some or most of the time, but their engagement levels seem good when doing it on a laptop via Sparx or MyMaths or whatever. Plus things can be a lot more interactive on a laptop/tablet. Being able to tweak values/variables/functions/etc and see how things change in real time, that's laborious to do again and again with pencil and paper.
> They're not learning computing.
No, but most will have that option to if they want. My kid wasn't interested and so didn't choose Computer Science as an option despite being able to do various simple things in python. Their interests lay elsewhere (sport, music, etc).
* I remember watching when my kid sat down at my work computer and wasn't fazed at all by the entirely blank keyboard I use. There was just a "oh, that's cool" and off they went typing away.
Driving on public roads is prohibited until a certain age.
That age is 17 here in the UK but me and many of my friends growing up in a rural area learned to drive from the age of 14 or 15 on private land. Our parents would take us there/back, provide the car and be our "instructor". Some friends who lived on farms had cars/trucks/etc of their own that they could use to drive around and their parents were fine to let us try too. But we knew that we were never allowed on public roads.
By the time we all got to 17 we applied for our tests and had a few lessons with an real instructor on real public roads. We still had to learn all of the rules/etiquette/etc but most of us where completely happy with the physical aspects of controlling the vehicle, that saved us a huge amount of time.
My kid is 15 and if a suitable opportunity arises I'll let them have a go behind the wheel (not illegally obviously). Unfortunately I live in a city not a rural area, and don't own a car, so there hasn't been the chance yet.
(In the UK land like a supermarket car park is still considered as public roads despite being privately owned. Generally anywhere where the public can access it easily is not considered "private" in terms of the Road Traffic Act.)
Exactly. In order to prove you are not 15 online you have to prove you are >=16, even if you are 63.
And there's no "I'm an adult" proof with leaking exactly who you are.
This is thinly veiled "we want to know exactly who is behind every account" legislation. Expect it to be coupled with the usual "If you've nothing to hide you have nothing to fear" argument.
> Imagine being 14 and having an entire laptop to prevent you from ever needing to focus in class.
Depends on the school obviously, but at my 15 year old's school they default to their laptops staying in their bag and only get them out for specific tasks when directed by the teacher. The rest of the time the laptop is in their bag. They don't just sit there staring at a laptop during every lesson and goofing around on the Internet.
Also all of these school provided laptops have pretty extensive keylogging/etc installed. The laptops are not provided for personal use and the school picks up pretty quickly on any student browsing websites they shouldn't be looking at or typing things they really shouldn't be typing, even when at home and not on the school's wifi. The students are all aware of this and cope quite well.
Leaving it in the bag sounds really reasonable. I'm not really worried about _where_ a kid goes on his laptop. Even if all you had was wikipedia that would be way more interesting than what you were being taught in your lecture. It's the opportunity for distraction here which is what I'm worried about rather than what the kid actually does online. (social media is its own problem, but I'm not addressing that here)
> One thing that stopped me from seeking the vanity plate
I'm sure it differs between countries but in the UK vanity plates have become reasonably contentious.
As a gross generalisation they're fine if the car is worth hundreds of thousands or the plate itself is worth hundreds of thousands.
The UK plate "F1" last sold for just under £1m (about US$1.3m) over 10 years ago and it's rumoured that there are offers for ten times that from someone who wants to buy it now.
It comes down to a classic British issue of "class", which is inherently difficult to explain.
If you have the money to have, say, a Ferrari 250 GTO then you can do what the hell you like with it, including getting a vanity plate for it. You are rich enough that you don't care what anyone else thinks about you. Anyone seeing you and that car will know you are rich.
If you have the money to spend close to £1m on a plate like "X1" and decide to put it on beat up 15 year old 1.2 litre Ford Focus then, again, it shows you have stupid amounts of money and some delicious irony in putting it on an old beater of a car.
But if don't have a supercar and you get a relatively cheap vanity plate like "RMZ 1327" and stick it on a Range Rover Evoque that's only a couple of years old then it just shows that you're trying too hard and just aspire to be seen as rich. You don't have enough money for a really nice car, or a really exclusive vanity plate.
I guess the other way of looking at it is that people who don't have the money to get a vanity plate aspire to being able to do so as it would mean they have more money than they have now. Once they get to having that amount of money most realise that the money is best spent elsewhere (or not spent at all). Once they have so much money that having a vanity plate is inconsequential to their finances they may as well do it. So it's natural that some people want to pretend they've reached the "rich" state by buying a vanity plate preemptively - the problem is that this is so easy to spot it just looks gauche.
All of this obviously doesn't apply to countries where vanity plates aren't traded for stupid amounts like famous pieces of art.
Loved your description of the class system. There's a general theme of old money wealthy people not caring about vanity purchases because they don't know how much stuff costs nor if that is a too much money or not.
It's interesting to see how luxury brands have different segments of clothes that range from no logos at all to a huge alligator the size of your chest, depending on whether you need to announce to the world that you made it or if you just want to have access to good quality clothes.
Yes, the classic description for a member of the British Upper Class is someone who looks down on people who have to buy their own furniture.
(One classification of "upper class" is someone who has never had to buy their own furniture because they inherit it and pretty much everything else they need.)
In CA and AZ vanity plates are first come, first served. You cannot sell them either. You either keep them on a car, or you can keep on paying to keep it out of circulation forever. But once you give it up it goes back to the pool, and someone can get it.
Also, my vanity plate is $0 more than a normal plate. Why wouldn't I?
Yeah, but the plate itself was $100/year last time I looked, which is outrageous. (It looks like it's $50/year now. I swear that's lower than it used to be)
This. When I moved from Ontario, Canada (where they charge a yearly fee for them), to CA, I was all excited to get a vanity plate - until I saw they also charge a yearly fee..
In the most ironic twist of all - Ontario did away with license plate renewals a few years ago, and now, I would actually consider a vanity plate..
I've always wondered if a regular plate was better for avoiding speeding tickets - a vanity plate is much easier to validate, IMHO.
I had a friend who used to work as a QA for an ANPR parking system. He said that they had to investigate an issue where the car with 11111 kept appearing in the system as unpaid, but at different places across the network at the same time.
The issue turned out to be drain covers in the field of the view of the cameras, which the system was detecting belonged to car 11111.
> I'm imagining someone driving in England and the police having no way to input those letters into their system.
I would assume the UK has worked out a way of dealing with this having had plenty of years of foreign plates being driven around the country.
Any Danish license plate driven in the UK will almost certainly have to a be an EU style plate with the blue band on the left with the "DK" country code. If someone needs to send a fine to the registered owner of this plate I'd guess they'd be handing over the camera footage/images to a contact in the relevant country and letting them confirm what the exact plate is.
(There may be some weird exemptions for old classic/vintage cars that can continue to be driven on their original number plates, in which case you really don't know who to contact.)
The UK is very strict on license plates. I don't think there's any valid reason for driving a car without some form of a license plate on display (cars being driven on trade plates placed in the front/rear windscreens are the closest thing I can think of). I'd expect the UK Police to pull over any car that didn't have plates on it if they spotted it. It's certainly considered very suspicious in the UK if a car is missing either of its plates.
>I would assume the UK has worked out a way of dealing with this having had plenty of years of foreign plates being driven around the country.
Based on my experience, the UK approach is to not even bother and try and collect fines from owners of foreign registered vehicles. They do sell them to some private company that has been sending me scary letters for 10 years soon.
My understanding is that most countries just don't bother; I once drove around North America on Danish plates; since European plates are much wider than North American style plates, none of their cameras could scan my plates; so camera-only toll roads were essentially free for me. I consider that it happens so rarely anyway, that they don't bother.
Similarly, I've been flashed for speeding in France, which does have cameras adjusted to my plates' size, but they also didn't bother sending a ticket. Germany - on the other hand - will send you a ticket, but since they allow Ö, Ü, etc. on their plates, their system can probably handle Æ, Ø and Å as well.
Edit: Obviously, they don't bother to a degree; severe infractions will obviously make local law enforcement do something, but it's a rather manual process. Most countries are signatures to a treaty, that recognises other countries' plates.
