hi everyone!
I just tried to play PUBG for the first time since 1.0 and apparently I'm getting memory errors so that's fun
proven olive
Computer memory errors, or biological memory errors?
Either one can make playing games annoying
elfin wave
ha. well I'm sure I'll have forgotten how to play, but with the video card
the solution online seems to be "buy more ram"
instead it will be "don't play PUBG"
proven olive
How much RAM do you have?
elfin wave
8gb. so, not much, but I'm also not going to spend any more money on the pc right now
I might try uninstalling reshade. that was so it would run better but it might be more trouble than it's worth
proven olive
Not a terrible amount of RAM. I know DDR3 is fairly inexpensive, but at the same time, inexpensive is still not free

it would be good to upgrade but we're also supposed to be closing on a house in a week 😃

@sleek urchin I used Unity with Ubuntu for years. Recently I switched to cinnamon (the Mint UI) on Ubuntu 16.04 (xenial) and am quite satisfied. I installed it using this PPA, which keeps it up to date: https://launchpad.net/~embrosyn/+archive/ubuntu/cinnamon

@sleek urchin I usually keep one login configured as the Linux Distribution had intended -- following the path of least resistance -- to see how the designer meant the user to experience Linux.
For day to day work I bypass that, making use of an ~/.xsession file, which can be as simple as the name of a single program:
$ cat ~/.xsession
fluxbox
Seeing as how this works for me under a straight Debian installation, I haven't looked into the matter further. I do keep one laptop with Ubuntu on it, and occasionally bring that one up to date: it pretty much rests in a storage box (I don't know exactly where it even is, at the moment).
Logging in one time only, with the default environment (prior to installing .xsession) seems to help put the glue in the right spots, for a new login account -- I think I had to do so, once, to bring up proper audio support for that login (I use several logins for different purposes on a single machine).

stuck moth
know of a good technical write up?
flat lynx
https://meltdownattack.com here are the papers for both Meltdown and Spectre
quote from Spectre's paper:
Modern processors use branch prediction and speculative execution to maximize performance. For example, if the destination of a branch depends on a memory value that is in the process of being read, CPUs will try guess the destination and attempt to execute ahead. When the memory value finally arrives, the CPU either discards or commits the speculative computation. Speculative logic is unfaithful in how it executes, can access to the victim’s memory and registers, and can perform operations with measurable side effects. Spectre attacks involve inducing a victim to specula- tively perform operations that would not occur during correct program execution and which leak the victim’s confidential information via a side channel to the adve sary.
Spectre-based exploits can be patched, but Spectre can't on its own without making new architecture
Almost every system is affected by Spectre: Desktops, Laptops, Cloud Servers, as well as Smartphones. More specifically, all modern processors capable of keeping many instructions in flight are potentially vulnerable. In particular, we have verified Spectre on Intel, AMD, and ARM processors.```wait

A great deal of work lies ahead. Software security fundamentally depends on having a clear common un- derstanding between hardware and software developers as to what information CPU implementations are (and are not) permitted to expose from computations. As a re- sult, long-term solutions will require that instruction set architectures be updated to include clear guidance about the security properties of the processor, and CPU imple- mentations will need to be updated to conform.

There are several fundamental unsolved problems here. Heinlein talked about one of them in The Moon is a Harsh Mistress but I haven't reread that one in context of modern I.T. practice. There are others (early attempts at copy protection schemes on distributed hard media such as write-once CDROM style optical storage, comes to mind).
Another one is the ability (essentially) of an outside entity to 'take over' your personal property (your computer) without permission (and perhaps without a whole lot of access to your machine, physically or on a connected network).

Why do real MPPT chips cost so d**n much? I mean, that's sort of rhetorical, but STILL
The SM72445 is about the cheapest, but it's $11.68 in singles and you need an external H-bridge MOSFET driver... the recommended one is $4.56 in singles.
And there are plenty of things that claim to be MPPT but don't reall scan the panel to find the maximum power point.
And I kind of need a controller, because I want the panel to power the load directly if the battery fails open, which kicks out a whole class of charger chips, like the BQ24650.
And I really need buck-boost, because I want to harvest the panel power even at the lowest levels of insolation.
sleek urchin
Well, what is a MPPT chip? it's a small controller, with software, an ADC, and a MOSFET, right?
so it should be emulatable with a small MCU and the correct firmware

"Your key isn't legit" it claims "You'll have to buy a new key", it won't accept Microsoft Academic Alliance keys directly into windows 10, you still have to install windows 7 and then upgrade to windows 10. Another system I have outright wont let me use my legit Windows keys, even from Windows 8 which wasn't MSDNAA and wants me to buy a new license.
The 'free upgrade' was a coup.
@grave crest The only answer to the updates is to over-ride with group policy and/or run a local wsus server..

It's been over 3 hours. It's only 50% done. 50. %.
stray wind
Oi.
grave crest
@gray aspen I agree with your sentiment. It's absurd to go to such extremes. But I don't mean to argue with you -- but that is not the only answer 🏏 👊
[all joking aside, MacOS and Linux have been, and are becoming even more compelling of a solution]
gray aspen
A lot of complaints I read about the lack of control over updates and other parts of windows are mainly controllable using group policies.
gray aspen
@dusty citrus eh?
grave crest
@gray aspen Perhaps -- but I wouldn't mind having the feature reinstated -- the very feature that was present in practically every previous generation of Windows -- of being able to control what I download, when I download it, and when I may install it.
dusty citrus
There are bloatware in the latest version of windows 10 ever since the anniversary update
gray aspen
@grave crest Those features are still there
@dusty citrus Is that with a fresh install?
dusty citrus
yup
grave crest
I remember reading the group policy trick no longer works after the Anniversary Update...
gray aspen
Okay, I didn't see those being installed with an update.
grave crest
Maybe I read it wrong or the article was mistaken. I don't use Win10 as my main personal machine, so I don't fuss with it.
dusty citrus
I see
grave crest
I will agree, the bloatware is pretty obnoxious with Win10.
gray aspen
I'm not seeing anything in my start menu
grave crest
I have a Surface Pro 2 as a "spare" computer, running Win10. I remember decluttering all the bloatware...then a major windows update was released, which put all that bloatware back onto my machine. I was rather displeased.
gray aspen
Looks like Windows no longer has the group policies all listed by default and has started hiding them by making you create them manually/ with scripts.
(gotta give worth to your mcse obviously)
dusty citrus
I forgot about something that I think microsoft should stop doing
grave crest
For other reasons (hardware issues common with Surface machines), I just never use the SP2 as a daily driver. Backlight bleed, yellowish screen, weak wifi chipset (my wifi router is 10 feet away and has issues connecting. It's powerful enough to go through my apartment, out to the driveway, and into my car).
Oh, if you have Bluetooth enabled and Wifi, you'll have the wifi randomly drop out and the bluetooth with glitch (jumpy mouse).
dusty citrus
Look, the data sending thing is set to full
gray aspen
That's typical on most combo chipsets, kinda happens on the pi 3.
grave crest
@gray aspen Thank you for the article. You and I might be willing to do that, but my parents never will.
grave crest
And because of the principle of the matter, I don't think I will put that much effort into it -- not when the previous generation of windows was a simple radio button baked into the OS.
gray aspen
These are the settings you can change without messing with wsus.
start -> run -> gpedit.msc
dusty citrus
wow
gray aspen
Computer configuration -> Administrative templates -> Windows Components -> Windows Update
Automatic maintenance can be further configured by using Group Policy settings here: Computer Configuration->Administrative Templates->Windows Components->Maintenance Scheduler
If you set 'configure automatic updates' to 'disabled' then all updates have to be installed manually, apparently.
grave crest
I'll have to play around with that.
Still, much easier to do with Win7. I tell it to check for updates when I want it to. Bam. Done 😃
gray aspen
Windows 7 nicely put some of these options directly into the control panel.
It's great to have a VM of windows and mess about with group policy, you can entirely lock down the OS to prevent someone breaking it, or break it entirely
grave crest
And 8, and Vista, and XP, and ME....
gray aspen
Windows XP was very much an 'all or nothing' kinda deal. You either had automatic updates, or it broke, in my experience.
tame saddle
joining the convo late...i still remember the night I turned my computer on and received the "Welcome to Win10...we're updating your computer" screen. I was furious after having to uninstall W10GPX.exe or whatever that spam upgrade program was all those times; to no avail. yeah, took all night for that to finish (i was on ^7Mbps internet...don't miss that). The hiding/removal of settings is what irks me about Win10. But, at this point, I've adjusted and like certain things. The enterprise/corporate world did get a bigger shaft than personal though, methinks. My org has been struggling with it over the last year or so...
grave crest
Dad's computer auto-upgraded -- he hit the red X instead of saying OK, then NO. Which to be fair, is exactly what I trained him to do.
Took a long time to upgrade. With a very. unhappy. phone. call. to me. It completed, but nothing worked right. Able to log in, but fundamentally broken with everything.
So I went home, and spend a day trying to uninstall it (after backing up all the data). The uninstaller lied -- it failed, and failed badly. So I spent the rest of the weekend reinstalling Win7 and all of his software, devices, etc. Over a really speedy 1-2mb connection. Not. Fun.
tiny moat
Im back on my laptop!
grave crest
That's time that I'll never get back -- I had plans too -- because a company thought prudent to force their software updates on me.
So when I learned that Win10 forces updates on their users by default (without tricking the OS or denying ALL updates)...imagine how I felt.

@keen dock I'm guessing you are doing this for cosplay? In that case, you should wait for a cosplay event about the thing you want (Detroit: Become Human). Some people will create outstanding effects, surely using LEDs like tannewt showed.
tame saddle
@pure topaz AFAIK, its not really a standard number. Common terms like "4 ship", "6 ship", "12 ship" etc are used to describe the number of aircraft for a sortie/mission. I've seen all manner of number for squadrons, groups, wings; even two squadrons in the same group can have a different number of aircraft.

This is how a moment of my day goes:
- wash random dish in the sink
- notice the carrots in a bag need to be put away, and a piece cut from one of them for consumption
- remember the paring knife did not get washed
- find paring knife in 10 seconds
- begin washing the paring knife
- have no idea why I'm washing this paring knife, it's the wrong one for splitting hot dogs before freezing them (on the TODO list)
- go get the proper knife to split the hot dogs, and wash it.
- espy the bag of carrots (again) while washing the bigger knife
- Remember (only then) why the smaller, paring knife needed washing.
IF THE BAG of carrots wasn't within view, there's no way I'd remember why the paring knife needed to be washed (hey, they all do, eventually, but this is a good knife and I can take my time about it).
Generally, used at an hour of the night where running the water would be unkind to the upstairs neighbor, so it gets set down, unwashed.

When dealing with tech, I often use the "Kindergarten Approach" -- color code, compartmentalize, and make unique.
Color code for identification, compartmentalization for storage/transport, and make unique....well, that one is a bit harder. Use "keyed" cables so they can't be plugged in backwards or in the wrong port. Also, part of that is making so no two similar items are near each other -- forks + spoons vs. big forks + little forks [in a culinary world].

May I ask for some advice from some of the experienced people here?
I do CAD/3D printing for a company, and i've been designing and printing some demo parts for a bit, for some cash every now and then
I just got asked to bump up the production amount (to 200!), andthey're offering $2 for each one I make...which is a very tempting offer. However, I looked at an online printing service... and, guaranteeing IP protection, they can make 200 for around $150.. which brings up a good question of what to do.
I've mentioned those 3d printing services before, however the high road here is still to mention that again, as I would be slower, and more expensive... but also more reliable and precise...
any chance you guys have some insightful words?
tame saddle
@ebon temple you obviously know your relationship with the customer better than us. However, I would pitch the option to them. If it's a customer that has enjoyed your arrangement, the fact that you are honest about being slower and more expensive on this particular job, may appeal to them. On the other hand, it's possible that they realize they can do cheaper/faster elsewhere. I would try and pitch it in a way that is as honest as possible, but still outlines the advantages of future business with you (locality, design, etc). Tough decision...good luck. (Sidenote: if I'm a customer and I find out you sub-contracted on me for a fee without notification, I'm immediately cutting out the middle man. No pass go. No collect $200)
ebon temple
thank you, yeah, thats how I eneded up responding. I did the math for predicted filament amount/costs, and some time estimates, and compared it to the online service. I tried to make some pros/cons that balance things out. I have mentioned the online services before, which added another layer to the puzzle
thanks for that reply, cleared a few things up for me 👍
lol, i'd like to avoid the "go directly to jail, do not pass go" card, as I am a minor, and this "job" is less about the money and more about the references
tame saddle
it was a metaphorical reference to Monopoly. I'm assuming they're local to you. one interesting thing about manufacturing/production: faster isn't always faster or cheaper. say for instance, they task a design, but need to change it after production starts. if a larger batch and queue effort has begun, its more difficult to insert a change quickly, and the time and cost of faulty parts are multiplied (# of runs * amount per batch + total time). in single-piece flow production, the very next item can have the change, and time and cost of faulty parts are minimized. to bring that back to the local aspect, or even if you're not local but have lower barriers to communication (# of customers served, etc), you are better suited to quick-change orders with minimal wasted cost (which SHOULD be charged to the customer, most likely a discounted rate though, if they cause the change).
/end production rant (too much management/production training...it just kicks in automatically at this point) 😄
to summarize that garble: your ability to deliver cheaper and faster production changes is an advantage over a large print-for-hire hub (online or not)
dusty citrus
Opportunity cost for taking on someone's large job. Money up front, since you have to turn down small jobs to do the large one.
I'd throw on another hundred, too, for wear and tear on the machine.
ebon temple
very true, especially since i'm producing a tool
however this is revision #4, but changes definitely could be made in the middle
the filament cost for one part I calculated to be $0.07
or $0.12 depening on the filament
$2 is quite nice
tame saddle
@dusty citrus those are good points. but that last one...i'd be carefull with itemizing it. if it's never been itemized before, and i've purchased an equal amount over time, i might question it.
ebon temple

Cool!
Let's do both.
I'd like to get a sample of their quality ... perhaps we can order from them and you can make the first 200 locally. Do you think they would give us a sample of their product quality?
Do you know this company by reputation at all?
Thanks,

@tame saddle I'm guessing qty 200 is quite unusual so the charge, is also, quite unusual. ;)
"For less than qty 20 we amortize it ourselves. More than that, we have to charge for (depreciation concept verbiage here)"
Ask someone for a few hundred bux on a loan-investment so that 'we' isn't exactly untruthful. ;)
tame saddle
@ebon temple that's a pretty fair response. hard to read with regard to where they ultimately want to end up (again, I don't know the relationship/customer). but, since you're more interested in the reference...i'd say you can count on them either way.
@dusty citrus I would consider that "careful itemization", and wouldn't question it as a customer (though I may haggle on the cost). 😄
dusty citrus
Haggling's fun.
That's another thing: when the customer is fairly competent and willing to stay on reasoned terms, and is affable. That all adds up as well.

I don't have for-profit 3D printing/manufacturing experience -- but I have been on both sides of the fence. As a consumer, you love good businesses [like Adafruit].
It also goes the other way -- businesses love good customers. When I was doing a computer repair business, I'd be thrilled when certain customers came in. They were reasonable, a pleasure to work with, gave prompt payment, didn't throw you curve balls or slather on the drama.
I'd rather make a little less working with excellent customers than make a few pennies more, and be miserable all the time.

Hehe.
I never liked working the sales floor. It was a mistake my boss made often -- took off and left me in charge. I was hired for (and meant for) the back room, to do the repair work. Circa 1989, when (probably still true) all you needed was a #2 philips screwdriver to fix a home PC.

All seriousness, #2 philips will go a long way.

I have faith in your research and evaluation. Let's go ahead and order two hundred from them. I can email them a check or give you my credit card for full payment if they require it.
Also, go ahead and make as many as you can up to a maximum of 200 in your 3D printer.
No pressure from this end, if you fall short because of school work or some other project , I understand. Please don't let this project interfere with any of your classes, or projects.

Groovy.
There was a musician at New Music America (Hartford, Connecticut; long ago) who constructed very small toy vehicles with phonograph needles underneath each of the vehicles, such that it could drive around a vinyl LP. During the performance, the LPs did not spin; instead, the little vehicles drove around the grooves. He put microphones a bit more than a hand-span away from each LP (he had three of those). I think he also managed to do things dynamically with all of this, during the performance (which was enjoyable).
Somehow I understood all this from the back row of the (borrowed) theatre, working as a volunteer usher. Maybe there was some kind of video projection (don't remember) or maybe he was just good at the verbal part (not too much) of his presentation.
(checks topic) *.oO(good to go)
Probably used an audio mixing board and used the faders to 'perform' this piece, switching it up by moving the vehicles to another section of the LP (which was probably a custom pressing with selections he'd chosen for the performance). That'd be the way I'd do it, to keep it from being too linear.
Another fellow during the same week (it's a long festival) basically had a 2x4 piece of lumber, with electric guitar hardware carefully attached, who brought various hardware store implements (threaded rod stock comes to mind) to bear on the strings. Also an enjoyable performance.
Since it was a piece of lumber, he kinda went to town on it, and didn't hold back. ;)

@tiny moat I used to think about that a lot: what is the next technician to open this unit going to think of my work on it, today?
tiny moat
@dusty citrus Usually I find good notes on what happened, and most of the time the repairs are done correctly. This time all I have is notes on replacement parts and highlights in the schematictics.
dusty citrus
So is that a piece of thread not on the original deployed unit, with something removed to make room for the threaded pipe/whatever? I thought it was an RF connector, at first glance.
[What does the remaining stalk/knob do, 90 degrees away? The coaxial thing (far right) looks like optics (thread in/out to adjust focus.)]
thin canopy
@tiny moat Looks like an auxillary sensor or control port that they wanted to make electrically inert (grounded). Needs a proper shorting connector. Probably also has a floating shield connection, so grounding it to the chassis/frame may create some noise even if there's no inside sensor attached. Could it be or have been a positioning sensor or control rotational counter?
tiny moat
@thin canopy @dusty citrus This is my objective apurtur selector/adjustment. The schematics call for a +3v charge to be applied to it, but I have literally never seen another SEM ever (nor have any of my friends) that does this sort of thing. In this case, column ground is kinda special as the beam interacts with it all the way down, so you definitely want your obj apurture on either it or a good point ground. It looks like at the same time this was done the grounding harness was re-installed incorrectly. I am changing it over to a point grounding scheme and if I can find a connector for this then I am taking it back to the column point ground. The column is actually electrically isolated from the frame via the rubber high frequency vibration isolation stage, so I have a lot of control over ground.
thin canopy
@tiny moat Would a slight positive charge help to bleed off spurious beam electrons at that point of the column? A beam quality bias adjustment?
@tiny moat (disclaimer: I may not know what I'm talking about.)

@thin canopy That's pretty much my thought, but I just don't know. I haven't found any litterture or manual references to something like that though.

Im actually not making them with a microcontroller. I just take these little 40mm x 40mm x 28mm fans and wire them up to usb cables that i make up and people can place them into the fursuit heads to help circulate air and keep them cool
though i was working on a prototype diy voltage regulator that would allow you to change the voltage anywhere from 5v to 12v (roughly) and wouldnt go above that as to not fry the fans

much like the others making cooling fans i have a small variety of them and they vary in price. my lower 2 tiers of them are rather competitively priced and my best one is a little pricier than the other 2. But from what ive been told even my cheapest one is better than some of the other groups'

Yisssss. just gotta get my name out there for these things.
what do you mean by filters?
abstract violet
i guess that would decrease airflow but like carbon filters and such
would prolly only matter on the head section
soft thicket
ahhh. nah not really.
we use the fans to either bring air in and cool us or to move hot air out of the head.
Honestly im not sure how some people can run around in these things without a fan. They are wayyyy too hot to do that.
abstract violet
are the fans loud?
soft thicket
not really because they are running at 5v. but compared to what the other groups use they are a tad bit louder. only thing though (with any fan really) is once you mount it to the base that the head is made around, weather foam or resin then thats gonna disperse the sound through the head a little bit. like its a little louder in my own head because the foam spreads the vibration around throughout it. I can still hear but the airflow my fan provides is worth the noise
i mean, at higher voltages, like 12v, they are actually REALLY loud. but they are really powerful and move a lot of air that way
