26383 Shoreham Air Disaster - embracing failure and the AAIB
I'm a huge believer in embracing failure in technology - create a psychologically safe space where people can talk about what went wrong without fear or favour. No blame. The Air Accident Investigation Board (AAIB) is the absolute best in any business at this.


Not much will be written about this as it is now a court case and the pilot is being charged with manslaughter - but everything is in that report. Amazing work.

Every geek can learn from this.

26357 Dodgy batteries
Hello brain trust.

What are our thoughts on third party laptop batteries?

I very much love my X220 and don't want to let it go, but both of the official batteries I have are about a third of the capacity they're supposed to be now.

There are still official Lenovo batteries on the market (for 80 quid) but I would assume these things have been sitting on shelves for long enough that they're probably half dead anyway.

Are Chinese knock-offs really that bad? I'd have thought we were at a stage in battery technology where they're probably as good as the ones made in the 'official' Taiwanese factory anyway. But at the same time I'm very aware that the potential for disaster is fairly high in a Li-ion pack.

Another possible move is that these battery packs are just a big plastic case full of 18650 cells. It's within my capabilities to spudge one open and replace the old cells with new 'trusted' ones, but it's a lot of hassle if the chinese ones aren't going to set fire to my cock.

Any thoughts? Do you trust the Chinese?

That's fucking fantastic. I wonder if that'd be feasible in not-so-sunny england. I've seen the council put solar on their roofs now, but I can't imagine there's much throughput.

My grandparents house has a fairly feisty river flowing past it, I've always wondered if we could hydroelectric it. My granddad would love this too, I'll have to show him.

Oh man, I have always always wanted to do that. I don't know why we aren't doing a load more tidal and hydro in the UK, we're surrounded by water. Seems obvious, though I understand the engineering challenges.

That's exactly what I was thinking. I think it's plausible with that sort of power storage, too.

I worked for a restaurant once that was talking about piping steam and heat from the kitchen to partially power the place somehow. I do hope they did it, though it sounded a bit like a pipe dream (no pun intended) at the time.

> Perhaps the charge lost on a stored battery is still better than the charge that will be rapidly lost in the first few months of a shite chinese clone, but I can't find anything other than opinion on this.

My personal experience is that my own rebuilt pack with good Panasonic 18650s performed and lasted better than an old-stock original pack, which in turn performed better than all of the several cheap ones I bought in the Huaqiangbei market. In fact the only thing the latter were good for were stripping down to reuse with better cells.

26330 Curved Monitors
I tend to use a multi monitor setup, with some horizontal, some vertical. I have an ageing Apple 30" LCD and am in the market for a new, large monitor. Samsung do a pretty good 32" now that I have used, but I notice there are a lot of very large curved monitors around now.

I am sceptical - are they really better to use than two flat monitors, correctly positioned? Anyone out there with a curved setup?

That's pretty urrghh, for sure. I had a friend who bought one of those 'ultrawide' LGs and we just hated it. Too wide for games, knackered up sites like this, didn't even look good running something like i3 window manager, at least not as good as a couple of seperate monitors.

Would you mind mentioning why you didn't like it for games? It's slightly annoying since some games letter box as they don't support this wide a resolution (and this particular screen has a noticeable amount of backlight bleeding) but for games that do I find it quite nice. As long as your setup doesn't choke rendering the resolution and, for FPS games, there's an FoV slider you can just plain see more; I don't see the down side.

It was a very subjective thing for games - I actually don't like a massive FoV - if you do, it's no problem, but it makes me feel a bit queasy. Having ultrawide just makes everything visually seem a bit 'off'. Perhaps I could have gotten used to it. If you like it you like it, I suppose, but I could never get my head around it, no pun intended.

The only thing we ever found it useful for was showing a big long ableton or Logic project.

Alright lads.

Bad news, my £100 Tesco Hudl 2 shit the bed a while ago.

Unfortunately they've stopped making them, so I've been scraping the lower end of the market for a replacement. There's nothing really catching my eye as good value, even the wanky half-sales websites like Which? and CNET are saying as much.

My budget is probably £250 absolute max, preferably around the £200 mark.

>preferably 10" screen, as long as it's not distinctly noted as being shit quality I don't mind
>proper Android OS, nothing Amazon or Chinese proprietary
>expandable memory (32Gb+)
>smooth general operation and HD playback

I can heartily recommend torque. It's nicely configurable and as technical as you want it to be.

>want to change out the car radio into one of these little double-DIN Android/PC boxes that do all the things

I can recommend that too. The Pumpkin ones they sell on amazon are great, fairly powerful for what they are. The one I bought was about 200 quid but it came with a fuckload of accesories - two cameras, 4G dongle, DAB unit, and some other stuff. They've got surprisingly decent DAC on board too.

It's really fucking fun to run Torque live on it, especially since it logs quarter mile speeds and live graphs of pressures and speeds basically everything you want.

I'm about to start the painful process of hacking one into the Disco so I can have live terrain views for off-roading.

>Pumpkin ones they sell on amazon are great

Thanks lad, that was going to be my next thread - wondered if someone round here had done it. How well did it integrate with existing peripherals in the car? Mine is a VW with parking sensors (which I love), I would like to add the Pumpkin but don't really want to have to remove or rewire the existing microphone, speakers and sensors. Kind of hoping I just yank the existing radio out and plug everything back in, but I know how optimistic that idea is.

Yeah the OBD2 thing while live is fucking amazing. I have been trying out the various apps while having the Kindle mounted on the dashboard, getting the real-time graphs and that as you're moving is like something straight off the F1 pit-wall; only on an a VW MPV and using a fifty quid Kindle.

Of the three cars I have owned, my first two had OBD2 and I couldn't get any more info than your basic error codes at best on my first, and the second (a Volvo V40) would not talk to anything over OBD2, ever. I checked the wiring and fuses as best I could but it never did.

My car these days has OBD1, so God help me if it ever spits out a code.

Actually, that's often exactly how it works. I can only speak for the cars of about five to ten years ago because it's what I tend to buy, but typically if you have a thing that controls your radio, or puts sound through your audio system, it's all done through the ISO plug on the back. It's often plug and play, or at the very worst 'buy an adaptor from Halfords and play'.

The fact my 1994 Landy can do the volume on a 2017 Sony head unit should say a lot. Car electronics are pretty fucking primitive.

The first programming language I learnt was C++, but I didn't start to enjoy programming until after I learnt Python. I'd highly recommend starting with Python - unlike C-style languages it's quite far abstracted from the hardware-specific aspects like memory management, letting you concentrate more on application logic and get more done in less time. Despite being relatively easy for beginners to learn it still has complexity to master that makes it worth sticking with for a while, it's still my go-to for anything smallish I write myself.

I used https://learnpythonthehardway.org/python3/ as my primary resource to begin with, and found it pretty useful. It's designed with complete beginners in mind and covers most of what you need to get started without assuming too much. It's presented online as a "free sample" of the paid-for book, but personally I found the free sample more than enough to get started with.

I'd like to build a portable battery pack with which to use my laptop longer in the field. I've made a couple attempts with Chinese BMS boards that supposedly allow balanced charging and discharge/overcharge protection. However, the quality of these boards is very poor and they are always burning up or killing cells. I would love to to know if anyone has had success with a similar project .

I've used a couple for Raspberry Pi projects, but those were essentially just a a step-up and a diode plugged in to a LiPo. I doubt I could make a proper, safe board for higher power stuff any better than the Chinese. Maybe the best bet is to cannibalise a USB power pack?

Also, they do already make laptop power banks. I don't ever want to dissuade someone from making something themselves, but I use a Poweroak K2 which is 50kmAh and does 100W. It's nice. It's also about a hundred quid, mind.

I wouldn't go to the effort, because an off-the-shelf power bank with 19v output will cost you about the same as the components.

If you don't trust Chinese BMS boards, I'd suggest using an iMAX B6 balance charger and an RC battery pack. The B6 is cheap but reliable and will charge 6s packs at up to 50W. You'd only need to solder a couple of pigtails on to a boost/buck converter, saving you the perilous task of soldering directly to the cells. If you need really long running times and don't care about weight, you could use a sealed lead acid battery.

Managed to do this challenge. The way the code works is to make a table of equations describing the FSM to match the numbers, and then algebraically reduces it down to a single term. The regexes it produces are longer than they need to be but they work. Simple solution but took a lot of thinking to get there.

Here it is in action for n = 5:

0 = 0(0) | 2(1) 1 = 0(1) | 3(0) 2 = 1(0) | 3(1) 3 = 1(1) | 4(0) 4 = 2(0) | 4(1) 0 = 0(0) | 2(1) 1 = 0(1) | 3(0) 2 = 1(0) | 3(1) 3 = 1(1) | 4(1*0) 4 = 2(0) 0 = 0(0) | 2(1) 1 = 0(1) | 3(0) 2 = 1(0) | 3(1) 3 = 1(1) | 2(01*0) 0 = 0(0) | 2(1) 1 = 0(1) | 3(0) 2 = 1(0) | 3(1) 3 = 1(1) | 2(01*0) 0 = 0(0) | 2(1) 1 = 0(1) | 1(10) | 2(01*00) 2 = 1((0|11)) | 2(01*01) 0 = 0(0) | 2((01*01)*1) 1 = 0(1) | 2((01*01)*01*00) 2 = 1((10)*(0|11)) 0 = 0(0) | 1((10)*(0|11)(01*01)*1) 1 = 0(1) | 1((10)*(0|11)(01*01)*01*00) 0 = 0(0) | 1(((10)*(0|11)(01*01)*01*00)*(10)*(0|11)(01*01)*1) 1 = 0(1) 0 = 0((0|1((10)*(0|11)(01*01)*01*00)*(10)*(0|11)(01*01)*1)) regex: ^(0|1((10)*(0|11)(01*01)*01*00)*(10)*(0|11)(01*01)*1)+$

I'm in the market for some new headphones but I can't decide on which ones. I want to replace my old Audio Technica ATH-AD700s which have finally kicked the bucket after 9 years of use and numerous replacements of the headphone wire (this time the break seems to be somewhere in the middle of the headband, and I can't resolder it without breaking the headphones).

I've been looking at the AKG K702s as a replacement, but are they really worth the £130? It seems to me that the placebo effect and confirmation bias play a pretty big role in the perceived quality of a set of headphones, but I haven't come across any concrete evidence like blind listening tests that would back that idea up. Are human ears even sensitive enough to perceive a difference between something like a well-regarded pair of £30 Superlux 681s and a well-regarded pair of £130 AKG 702s? It's very difficult to tell the marketing dross apart from tangible technical differences.

They're large, heavy and have relatively low clamping force, so they'll probably fall off your head. I'd suggest some inexpensive in-ears from Xiaomi or Betron; if you can't stand in-ears, then I'd suggest looking for some "sport" headphones with a more secure headband design.

If you want an amp/dac that powers pretty much anything with minimal setup fuss, try JDS Labs’ The Element. Buy it once and forget it forever. As for headphones, well it depends what sound you want but you can’t go wrong with HD600s. Or 650 is alright too, bit more bass but not as accurate. None of that stuff is cheap but it’s not unreasonable. Audio stuff is expensive . But get to your end game quick with that and you can forget it all. Hopefully.

I ended up buying the Philips Fidelio X2s for 130 squid back in August. They ticked all the right boxes and since they're 32 ohms, I don't really need a headphone amp to get the best out of them. Very happy with them so far.

I also bought a pair of closed-back Superlux HD-662s which are pretty decent for £25, but the level of comfort is nowhere near as good. I think Superluxes are mainly aimed at the Chinese market so maybe they design them for smaller Chinese heads. It's either that or I just have an usually big head.

I use my headphones for gaming and it's important that I can hear stuff like the footsteps of other players.

The right ear of my old JVC HA-RX500s has stopped working, so by way of replacement I unboxed the Sony MDR-570LPs that I got as a Xmas gift years ago. They are awful, in no way approaching the sound quality of the JVCs. This will definitely affect my performance.

You still haven't quite grasped the "personal" qualification here, have you?

Merry Christmas everyone. Thanks to whoever suggested trying Vivaldi again; it is great.

If you guys are in your 40s some day and thinking about all the stuff you argued about on .gs, don't be embarrassed. Everyone does it, and it's harmless. Only boring people never did anything cringey in their life.

The filtering and search functions in Claws are pretty bad, as is the documentation. This page explains it better:


It doesn't really affect me, because I have very simple filters and use grep for any complex searches.

I miss Presto so much, I've tried countless browser hoping something could fill the void but nothing comes close. I don't want twenty extensions just to get the functionality I had ten years ago

You can determine latitude easily. Longitude is rather more difficult, for obvious reasons.

If you knew what day of the year it was and time of night you could definitely do it.

The time of night you could probably make some sort of estimate of based on the position of the moon after knowing the time of year. The time of year you could make a 'good enough' estimate based on which stars are present in the sky for a broad estimate and then use the phase of the moon to calculate a more exact date.

I have really no idea how precise any of this navigation would be based on eyeballing, probably good enough to get you across an ocean and in the direction of the right port.

If you had precision measuring tools and a sophisticated computerized star chart you could probably calculate your exact position on the earth.

It was not really known how to calculate longitude accurately until around the 18th century. The major way people determined it was by using latitude, speed and direction to estimate it using the ships vectors of movement against a known position.

I agree but the question was about ability to determine your position with no other points of reference.

If you flash anything over anything you'll lose anything you don't have backed up.

So I'll only lose custom recovery then? Not my data or apps, which I think are in user?

Not him but I think the term 'flashing' refers to formatting a flash drive, and you know what happens to the data when you format a drive, right?

The flash memory is partitioned into different areas.

It depends on what you're flashing. IIRC flashing stock images tends to reformat & wipe everything, but going to custom firmware often preserves things. Depends on what the upgrade script written in the image does.

Stock recovery... I dunno, I'm less confident that would wipe everything. I think recovery is a separate 'partition', so it'd *probably* be okay...

If your TWRP is still functional, I'd use the backup functionality if I were you to take a complete copy of your flash memory before you start. Just get everything backed up before you start; better to be safe than sorry.

I think we all seem to be talking about different things.

>>26219 seems to be referring to flashing stock over custom ROM

>>26222 seems to be referring to dirty flash

I will of course do a nandroid back up before fucking around. Just to be clear I'm on rooted stock android, and I want to go back to stock.
