I wouldn’t buy a non-brand laptop, but that’s not really a security issue.

I dunno, how paranoid do you want to be? Firmware hacks, compromised OS builds etc. E.g. the well publicised Lenovo system level vulnerabilities they were shipping. Supplier very much IS an issue.

The NSA publish guides to hardening various OS, but I can’t find a windows one from a quick google.

As above, something with S&S couplers.

So I had a similar issue – wanted to listen but still have people be able to get my attention etc:

that was my thread, still happy with the AKGs

I’ve ridden x-fusion any lyriks, I have lyriks on my bike….

One advantage of u4/3 compared to the sony, the smaller sensor keeps the lenses a fair bit smaller.

+1 for pretty much anything panasonic.

Though having said that, have some work olympus kit and they’re good too. As a human I prefer the handling of the panasonics tho (but the olympus lets you get a nice sensor in a smaller package which is nice for robot/drone mounting, and it’s barely used by a human directly so handling doesn’t matter).

Anything in the startup items folder in the start menu?

What do we do with it?

Reply, “ooh, tricky, i can have a look – would you fetch me a coffee and a donut?”

Is it just you needed to run ldconfig as a post-install step? Though not sure why it wasn’t automated in that case. I don’t have the time to try building iperf here for a closer look though.

To test, do your install from deb, then ldconfig -p and see if it’s listed (or something like ldconfig -p | grep iperf) if it’s not, sudo ldconfig and test again.

There’ll be a configure switch to set it to install the libs to the appropriate system path and avoid that faff.

Quick skim of that source code and the makefiles it looks like it builds the lib too? Of course whether or not you’re building them into your deb….

Try removing/purging the system libiperf you have, iperf, and reinstall your build deb.

Same process to build the lib, no quirks.

Running file on the offending .so may (or may not) be revealing too.

Yup. Where did you get libiperf from?

If it’s a debian arm build rather than a specific raspi one, it’ll be an armv7 build (or higher) but it needs to be armv6 or lower (different floating point capability).

Another thing to try would configure like this before you build it:

./configure --extra-cflags="-march=armv6"

(guessing here about what the configure script supports)

Ah sorry you have to run first.

Though my current thinking is you somehow have a build for the wrong arm instruction set version, but I forget how to check/change that…

Ok, so you’re building for the right arch.

I’d be inclined to have a quick look with gdb and see if it illuminated any more:

gdb iperf3

then bt to see the stack when it bails out.

Oh, and “–pkgarch” on checkinstall sets the arch the package is built for, FWIW.

A good start would be:

file which iperf

And that’ll tell you the arch it’s built for.

EDIT: Forum killed the backtics. Run “file” on the iperf binary you end up with.

E.g. on a x86_64 machine:
file /bin/ls
/bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=eca98eeadafddff44caf37ae3d4b227132861218, stripped

Don’t have an ARM box on to check that…

have some computing power to do analytics on the database and run simulations

If you’re even looking at Xeons and care about performance, go for the xeons.

AMD aren’t competitive just now on performance, though maybe are on cost in the mid/low range. Still, nearly everyone uses intel.

What sort of simulations, what sort of analytics? If you know this, surely you can answer the questions as to what sort of machine you need. If you don’t, ask whoever’s writing the sims/analysis code?

I do a lot of fairly high end computing, and the only thing that’d tempt me off Intel is power8 and I don’t have the budget for that…. that NVlink IO though…

(caveat to all the above, I do a lot of high end compute but DBs aren’t my thing at all)

Idle with screen off will be in the 5-15W range depending on vintage. Less on sleep obviously.

command-option-eject is the shortcut to sleep BTW.

No vast experience but having just done two bathrooms over the last couple years, the more recent one has this in:

http://www.screwfix.com/p/vent-axia-vasf100t-4-3-6-8w-silent-axial-bathroom-timer-extractor-fan/6468h#product_additional_details_container

It seems good. Steam clears, isn’t too noisy, doesn’t seem to let a draft in. In a wall rather than ceiling, but claims to do both. Maybe not as quiet as it implies, but it is quiet enough you can listen to the radio/podcasts in the bath ok…

Just to +1 the makita 453 advice above.

Though I also have a 10.8 makita drill and impact driver, which are both also ace – though if it was only one it’d be the 18v makita.

If it’s not right and your unsure get yourself there. I’d not be messing around with hands, they’re useful! Go seek help

Programing doesn’t look much harder than cnc. Just position moves linked together.

Gets harder when it’s not set moves, but “pick that thing” and you have unconstrained space with obstacles to move the arm through -solving fast enough to obstacle avoid is hard.

You’ve not clarified why you’re interested, which makes it hard to help. You’re asking very open ended questions (though maybe don’t realise it).

E.g. Why the focus on what makes robots safe – really you should ask what makes software safe. I can write software to spot a human, and avoid moving an arm into them – but then the question is how safe is that software? How reliable? Will it always detect and avoid in time?

However there is some work making robots designed to be safe in that they’re elastic, enough strength to do a useful task but some give to keep humans safe. HRI (human robot interaction) is also a big field of study (that I’ve worked in). I know there’s research within the ERC (Edinburgh and Herriot watt) into collaborative robotics for manufacturing tasks.

And the software isn’t just about guards, it’s about understanding intention – what is that person going to do? How do you help them? Avoid them? Keep them safe?

I mean what could go wrong…

“robotics” is very vague and far reaching. Could be anything from small mobile platforms that are at most a trip hazard, up to large Kuka arms that could throw you through the air or snap you in half!

Surely you know what you’re doing/wanting to do with robots? Give us a clue…

(i work in robotics and autonomy R&D, less on the manufacturing side, but I’m less clueless than most)

they will box in with wood on the inside and not horrible UPVC

We have horrible pvc. Yes, it’s not as nice as wood, but it’s not horrible, it’s “fine”. Budget-wise the choice for us was casement or these sash, these are a big improvement over casement, not as nice as wood would’ve been.

Yes, as above I’m sure I could’ve paid “only” a hundred (or two) more per window for wood inside, but I’ve also substantial other renovation work to pay for, and there’s never enough money for everything – compromises have to happen somewhere.

I can recommend CR windows for UPVC sash, if going that route in bristol. That wood would be pulled out and replaced with UPVC.

I agree wood is a better option, if you can afford it.

Perfect Curve Glacier neoprene gloves. Only for the very coldest days but these neoprene window cleaning gloves are the warmest I’ve ever tried.

See also Skytec Argon. £6 a pair, perfect for the winter commutes. Even come in a lurid yellow for safety.

CPUs specifically, and modern smartphones. Incredible the technology in them.

I mean in an old iPhone 5S say, there’s a billion transistors in the SOC alone. A billion things. In such a tiny space! And humans made that. incredible.

How did you get on with these?

Roku streaming stick is half price on Argos just now (£20) and is the only stick to do _all_ the services – plus you get a remote rather than needing to use a phone/whatever to stream to it.

Otherwise, chrome cast is cheap and has a great netflix implementation if you have a device to drive it.

At 6,4 I used to ride an XL giant, so XL I’d say.

Like me, I doubt you meet many folk taller – if an L was right for you why would they make an XL for a nearly non existent market?

If I could afford for space not to be an issue, I could afford some sort of bike butler/valet. So who cares how they’re stored.. ;-)

“Jeeves! The gnarpoon today I think!”

Just to address some wrongness above:

Extra ram doesn’t help slow disk io/random access in any meaningful way.

It’s PCIE ssds in the iMac, not sata, they’re about 4 times faster than a sata drive in usb3. I know, I have both. 2 gig a second vs 4-500Mb, and that’s just bulk transfer. They’re also more expensive, but yes apple charge a fair chunk….but then there’s no competition for the 5K iMac.

Drlex is a bit out of date, the latest 5k iMacs with the p3 screen have sky lake chips.

Anyway, great machine (I have one) but don’t cheap out with a fusion drive* get a proper SSD.

*on the latest 5ks it’s not 128 flash it’s much less, so more cache misses.

Fire up “console” and look in the logs at the times the problems occurred.

I think the real horror here is you know enough about computers to swap drives and run linux, but you’re still running spinning HDDs like an animal. ;-)

Bit bolting-the-stable-door, but maybe you could replace her dead HDD with a nice fast SSD (cheap these days) and a portable HDD for (automated!) backups? Cost you <£100 all in, might go someway to making amends…

As I said, download a gpx however (lots of ways) and open in goodreader, then mount the device on the mobilelite and copy it across.

I’ve downloaded, unzipped and installed an OS image to an SD card to boot a raspberry pi like that, gpx be easy.

If it mounts as a drive, you could do it wirelessly with a Kingston Mobile lite g2/G3.

They let you copy stuff on and off usb drives etc using anything that can mount a samba share, like goodreader.

Isn’t it basically Ingress Lite?

Made by the same people, after they spun out of Alphabet.

Just in case anyone wonders why I’m deffinitely not using RM:
