Also spotted on my daily bicycle ride, a vintage Ford...

A new Ford...

That's the owner in the first 2 pics (and my fixie in the first), he was properly chuffed (translation: He was very pleased... Why am I translating this? Learn English, you heathens. And God save the Queen.) that I pulled up to take photos.

Want to do a grand tour? This is your ride...

2017 Porsche Panamera 4s. Base price, 103,000 USD. That gives you a twin turbo V-6 with a top speed of 179 mph. Upgrade to the V-8 and add some options, you're over 200 large.

-edit- Looks like base price and power have come down. 85 grand, 330 horsepower, 0-60 in 5.4 s. That's not the engine I'd buy if I had the money. 330 with turbo-lag would suck in that heavy car, I'm guessing.

I don't usually like cruiser-type bikes (I prefer to go fast make progress) but the Scout Bobber is simply gorgeous, nicer than Triumph's effort, IMO.

Not sure about those cages[1] though...

a whole week without any off topic chat?
what's going on!

anyhow, i came into some money unexpectedly, and wanted to ask your opinion what i should do with it (or some of it).
investing in hardware, that is.
desktop & phone, are my main targets, but really anything goes (peripherals=screen+mouse+keyboard+speakers, tablet, laptop...).
would love to invest in reliability, expansibility, openness, security.
let's say i want to spend max. 1000€ on one device, and 2 devices max, but that's just to give you a rough picture of my budget, it could be more if there's a compelling reason.

i'm only a casual gamer, but multimedia capabilities are a must.

^ i was thinking that myself!
anybody has a clue if there's a performance hit?
explanation:
currently, i use a 1680x1050 monitor (yes, it's 16:10!) on an intel i3 6100 (iirc) with integrated graphics, well supported by the current 4.14 kernel.
i can play e.g. supertuxkart 0.9 with the second-lowest quality settings smoothly, and watch all the movies i want if they're not insanely hi-res.
suppose i get myself a significantly higher resolution monitor, what's going to happen?
according to this, 3840x2160 is currently the top, and that would be 4.7 times as much as i have now.

but my foremost advice-seeking topic would be a new phone.
would love to go wild with something that is ethical both in the hard- and software.
fairphone2 would be great because it is "built to last"... that, with an equally ethical OS ...
other considerations?

^Which OS do you intend to use with that phone? Luckily there are a few to choose from.
That phone is more on the expensive side (400-500), but it's modular, so it might be even a good investment in the end.

There is a new bug I have been bitten by ... makes showing desktop after boot slow (we are talking about tens of second, or even 100+ secs). Possibly related to https://forums.bunsenlabs.org/viewtopic.php?id=4789 or similar.

(Normally, I wouldn't report such obscure bug here, but it might affect lots of users, and at this moment seems very difficult to recognize that it really is that bug.)

Symptoms: unusually long boot (or 'show desktop') times, tens or even hundreds of seconds

How to recognize symptoms: after boot, go to terminal and execute

$ sudo dmesg
...
[    3.820698] random: systemd: uninitialized urandom read (16 bytes read)   # lots of these lines
...
[  127.969588] random: crng init done     # this one line; note the time
...

Workaround: maniacally press keys on keyboard during boot 8) 8) It will make 'random: crng init done' line quicker (check with 'dmesg'). I can personally confirm that this works (time: 127 sec --> 5 sec). Other people on internet experience the very same effect ...

Explanation: both systemd and other services ask kernel for random numbers during boot. Some services need high-quality - read cryptographically-grade - random numbers (cryptographic services like sshd), some don't (like systemd). Unfortunately, systemd seems to exhaust the kernel random number generator, hence kernel waits for more entropy. After it collects enough entropy, it generates new random numbers and boot can continue. Since some entropy is collected from keyboard, apparently pressing random keys (or even single key!) during boot shorten the waiting time.

Affects: it seems to affect newer kernels like 4.16+ (I was affected when I updated kernel 4.15 --> 4.16); but I might be wrong, perhaps some 'subsystem' of the kernel gets updated irrespective of the kernel version; also it may depend on actual hardware.

Disclaimer: I am in no way expert on kernel stuff or systemd stuff, so take above text with caution, as my understanding of all this is incomplete (and might be wrong).

Literature:
Systemd/Poettering won't(?) fix it and link therein (bug seems to be about plymouth, but lower posts explains that it is about random number generator during boot).

EDIT: improved Literature part

@iMBeCil, try

sudo apt install haveged

iMBeCil · 2018-05-08 20:28:06

^Thanks a million HoaS, it solved the problem with slow boot. Nice find/advice!

For the reference: now I have (without pressing random keys during the boot)

$ sudo dmesg | grep random
[    0.000000] random: get_random_bytes called from start_kernel+0x94/0x478 with crng_init=0
[    2.561532] random: fast init done
[    3.287944] random: systemd: uninitialized urandom read (16 bytes read)
[    3.294224] random: systemd: uninitialized urandom read (16 bytes read)
[    3.300520] random: systemd: uninitialized urandom read (16 bytes read)
[    3.306851] random: systemd: uninitialized urandom read (16 bytes read)
[    3.313233] random: systemd: uninitialized urandom read (16 bytes read)
[    3.319650] random: systemd: uninitialized urandom read (16 bytes read)
[    3.326132] random: systemd: uninitialized urandom read (16 bytes read)
[    3.332733] random: systemd: uninitialized urandom read (16 bytes read)
[    3.338113] random: systemd: uninitialized urandom read (16 bytes read)
[    3.343214] random: systemd: uninitialized urandom read (16 bytes read)
[    5.213253] random: crng init done

To conclude: systemd still exhaust random generator, but at least '[ 5.213253] random: crng init done' doesn't slow down boot process. Compare it to previous 100+ seconds ...

Thanks again, HoaS.

suppose i get myself a significantly higher resolution monitor, what's going to happen?

i looked up the processor and its graphical capabilities.
the Intel® HD Graphics 530 is supposed to support up to 4096x2304, which would be good enough for me.
how would a significantly larger monitor affect normal Xorg/openbox usage (*)?
where can i get more info on GPU/Monitor relations & performance?

(*) i finally managed to compose a search phrase that yields useful results.
most answers (even if the questions aren't) are gaming related, and the answer is a clear YES, big performance hit.
so now my question is clearly only about Linux Xorg Openbox usage.
the answer will most likely be yes again, but i have no idea about the severity of the impact on system performance.
Let's assume, for arguments sake, i go from 1680x1050 to 3840x2160, which is 4.7 times as much.

You might want to try updating your system and removing haveged, some folks over at forums.debian.net are reporting this as fixed.

iMBeCil · 2018-05-10 11:38:11

^Thanks for the info ... will try in a day or two.

EDIT: yes it seems to be fixed ... I can boot normally without haveged installed. Thanks once more.

Warning for any Arch Linux users who have the [Community-Testing] repositories enabled: blender v17:2.79.b-8 is broken:

https://bugs.archlinux.org/task/58514?p … ng=blender

So tell pacman to ignore it don't update until the next version is pushed out.

^ nice blog.
there was another article about animal intelligence, arcing gently over to human intelligence and alternative education...

All these GDPR notices people have been getting in the mail - Genuinely surprised I've gotten so few (mostly asking to resubscribe to newsletters or reminders to read new forum policies). Was half expecting evildoers to spam me with phishing schemes or malicious javascript executing buttons.

On a side note, is it only me that thinks Trump and Kim Jung look like they're related?

^ personally i think it's finally happening - the rules (laws, whatever) are finally catching up with www realities. i welcome this.
emails asking me to give my explicit consent if i want to continue receiving this or that newsletter... common sense told me this ages ago.

Valentino Rossi on pole for the Italian MotoGP?

Crazy Joe (Andrea Ianonne) topping the timesheets in every practice & warm-up session and with a point to prove after being sacked by Suzuki?

Marc Marquez ominously fast in warm-up practice?

Mugello is going to be awesome...
