Be damned careful here

Very high side effect profile, ESPECIALLY if you pull a 'me' and go back to work or chores too fast! Very poor circulation down there - infections can get nasty and can be with you for a really long time. As in permanently. I've had to have multiple repeat surgeries just to remove crap from down there. Not quite as much a problem as cancer but its been life changing... Think I'm turning into ... Frankensack!

Seriously, this procedure has one of the worst side effect profiles of any elective operation. Do your homework. And if you're definitely going to get nipped, make sure it's with a doc who specializes in it and have it done in a proper hospital - increases your odds.

Take your time and do research. For most guys in the point of marriage where you are under orders to get snipped, you are not gettin any anyways, so what's the rush? Patience.

My understanding is that male hormonal birth control is under evaluation- definitely a thought.

Re: Strain and stress

@Evertime; good points but the devil is literally in the details and why a professional engineer won't typically answer a 'is conventional or additive manufacturing better?' question with anything but a 'it depends' answer. One can harden AM printed gears. Surface peening is an option, and is electroplating, exotic lubes, and so forth. Nearly all the materials post processing used for conventional parts are applicable to AM. Of course one can fail to design the gear well and all the king's manufacturing men cannot make a go of it. Or truly excellent mechanical design can make a go of a product even with crap materials and processes- the key being knowing just what quality you have. Or I can overthink my gears to the point where they outlast my otherwise dodgy product and I go out of business having spent too much capital on my lovely gears.

So many tradeoffs... This is why engineering is an art, really - making the best product humanly possible is fun. But making an economically competitive, safe, "good enough" product that users like is both fun and bloody difficult!

Material properties

If you are an engineer seriously interested in material properties of additive manufactured materials, I'd recommend getting in bed with NIST (link: https://www.nist.gov/document-3511) or its UK/EU equivalent.

I haven't worked with NIST on metal AM but know they've got access to just about every polymer printer under the sun and a spectacular set of materials data and at least an equivalent if less mature program on the metals side. For my polymer work the relationship has proven essential.

Absolutely have your prospective vendor print standard ASTM coupons and perform proper materials testing. If you cannot do so in house, materials test houses abound and can provide full traceability. Try different lots of powder. Try powder from the top and bottom of a cartridge. Try powder that is new and some that's been stored right at the margins of its storage envelope. For polymer printers, test parts printed at all corners of the materials' temp and humidity space. You get the idea.

The people I know who do DMLS in a production environment always include two test coupons (x-y and y-z axes) and do at least a basic yield measurement on every single one to catch any process drift. Fatigue strength, hardness, etc are occasionally tested per SPC.

The bottom line is that there is nothing inherent in AM that absolves you of the need for robust processes control. Indeed until many thousands of hours accrue in a given process one tends to keep a weather eye on outcomes.

Note that you generally still need some CNC capability to.clean up parts post-build, no matter what the salesman claims.

@cray74, truly excellent post.

Ive been using the porous, brittle crap from the 1990's and have actually found it of some use: its good enough for form and fit prototypes. Sometimes we can use it to build mold sets for injection molding. But the real niche is that it makes it easy to build tools and jigs that facilitate conventional production, inspection, and test. Granted the photopolymer printers do this for me a lot more, but sometimes a metal jig that can take some heat and abuse, yet simplifies some other task ("robot" handling PCB in vacuum chamber, reflow oven, etc)

Of course Im benefittting from a sunk cost from years ago. All I have to do is justify the continued tax on depreciated capital equipment. Justifying a few hundred grand on a low end printer to build production gear can be ... difficult.

Don't worry about those 40 Linux USB security holes. That's not a typo

Chairman of the Bored

Physical access is physical access ; you've got insider problems

Yes the holes need to be plugged and the number is high. But I give the researchers credit for an enjoyable fuzz job.

Some perspective though... let's say I'm feeling a little evil:

If I want to steal your data I will just grab the HDD. Max 30sec. If I first just do a recon to figure out your make and model then replace like for like on second pass... will you really notice the change or will you just assume the HDD failed? Does your org track serial numbers? I do. Data at rest encryption is your friend here but it is not perfect.

If I want DoS whats to stop me from hacking a usb plug and mains plug into a plug of death adapter? Your motherboard will not survive mains being applied from USBP to USBM. Time to attack? Seconds. Platform independent.

What if I want deniability? Shell of USB stick in parking lot. Guts replaced by photoflash cap charger, cap, spark gap. Either label it as pr0n or an official software install disk. Costa a few bucks and needs only technician skills.

Or what about a kilo mixture of potassium permanganate and glycerine inside... heck, anything you want to experience a Viking funeral (DONT do this at home, kids).

Point is that if someone wants to do you in and they have access, how much can their OS help?

Re: 20 layers you say.

@short,

Thanks for the photo; good stuff.

Regarding lack of full pot on assembly, there are a few reasons: with the increased mass comes lower frequency eigenmodes and therefore greater coupling of shock and vibe into your boards and solder joints. Phone design has the luxury of using really small boards with high freq responses- show me a 40cm x 40cm, 20 layer board that does well in shock and I will be truly impressed. 5cm by 10cm not as much.

Thick conformal has a lot of gotchas possible with respect to differential coefficient of thermal expansion stresses... and if you fail to degas it you can get little bubbles giving rise to ideal gas law-driven thermal stresses...

Unless you are doing high voltage or anti tamper a little dab'll do ya. This is one area where "the bigger the blob the better the job" is NOT the way to go.

Chairman of the Bored

Re: Confirmal Coating

*laughs* love your Apollo 13 comment and observation. Have an upvote and a brew.

What I find funny here are the people who do a crap job of cleaning boards and then blissfully encapsulate with a great coating and wonder why they get various plagues... or fail to bake out components prior to reflow or high vacuum... so many ways to FAIL! And theb they blame the conformal chemicals...

Chairman of the Bored

Boards and coatings

For high performance RF / mixed signal PCBs I don't find 20 layers particularly heroic. What IS novel is being able to make them really, really cheap. Mitigating factors: the frequencies involved in an mobile are not particularly high. The boarda are physically small, which alleviates a lot of differential coefficient of thermal expansion-driven problems. Design lifetime for a mobile is a small fraction of what we need in, say, aerospace or biomedical space.

And then the big gun: modern design and production test methodologies such as halt/hass permits the cheapest possible acceptably robust boards.

Conformal? Almost certainly something like parylene C, applied in a fine (order of thickness... microns) layer through chemical vapor deposition. Used to be only for military / space / biomedical. But if you can afford cvd - and Foxconn can - its What You Do. Perfect control of layer thickness. No meniscus stresses or cte problems - layer too thin. Totally impervious to water and most solvents. You will find the current state of the art uses nanoparticles like aluminum silicide to make the layers hygroscopic.

So I know you guys can do a proper job of this, must be something odd going on.

Re: What shall be done about civil liberties?

@six, same on this side of the pond. In many communities the plate recognition cameras are ubiquitous. My assumption is that most of these are controlled by the local sherriffs' offices but their use is only rarely revealed in court.

One problem is that their existence is used to justify ever more intrusive surveillance. For example I've seen the argument made that warrantless vehicle searches should be ok because you have "no reasonable expectation of privacy in a vehicle". Why? Presumably because we the people are supposedly ok with the plate cameras, indiscriminate use of stingrays, etc. Its tough to climb up a slippery slope...

Chairman of the Bored

What shall be done about civil liberties?

I love tech and wouldn't mind some level of automation to help me with the insane drivers I interact with on the I95 corridor. And to be honest, I too get sleepy, complacent, and boneheaded.

But I guarantee you that the lawyers will see V2V as a potential gold mine of data to support whatever personal injury litigation perspective they are being paid to litigate. This may or may not be a good thing. Regardless we need to consider up front what data are publicly available and what is covered by amendments 1,4,5. Yes its a short range protocol but Im having trouble imagining any scenario where your data is not stored in your vehicle's ECU and/or backhauled to Google or equivalent.

What really concerns me is potentially allowing local law enforcement real time access to data. I can easily see something like getting a traffic stop and 'cooperative search' because a database says Ive just driven from a 'dangerous political rally' and another database helpfully adds that 'I'm driving while black', combined V2V data that says Ive been driving in an environmentally irresponsible way... etc.

Participation would be a lot higher is it would stick with its Constitutionally mandated requirement for a headcount permitting apportionment of seats in the House of Representatives.

Their so-called 'American Community Survey' is so invasive It borders on a violation of the 4th amendment protection against unreasonable search and seizure. The survey is not voluntary. Not that we bother using our constitution any more, mind.

Last go around had us detail: income, education, mortgage debt, marital status, race, religion. At least in my area canvassers were also recording lat/lon of residence entrances - at least until such practices became widely known.

Type 23 shallow water?

@dmacleo has a point; the 23s are pretty good platform for littoral work. Especially when the type 997 radars are fully deployed. I dont know much about the new modular anti-air missiles but what Ive read in the trade journals sounds encouraging. Eight Harpoons plus a 4.5in gun, helos, and perhaps some Royal Marines embarked makes for a pretty compelling package.

Draft is about 7 meters and change, so these will not be doing any brown water work but the weapons and sensors have decent range.

Type 23 is mainly an ASW platform intended to keep the N Atlantic commerce flowing. At this it is truly exceptional.

The USN counterpart, LCS, is comparatively unarmed. And vastly, vastly more expensive. Unless you are fighting a girls' primary school LCS will probably need to be defended by DDG-51's, which are definitely not at home in the shallows...

Chairman of the Bored

I was going to say 'unbelievable'

But why? USN has already been there.

We set the example by cutting costs through removal of the FFG-7's AAW capability... only to realize a figlet with no AAW capability is about as useful as a football bat. Supposedly the ships couldn't be upgraded, but that's a rather hollow argument when you look at what the Taiwanese can do with the same hull. The excuse being that LCS - a frigate in all but name - will somehow be better and do more with fewer hulls. LCS? Think of an F-35 that floats, but without weapons and built to commercial spec.

The OHPs were decent ships but I'd love to have something like the Type 23s. Brits have done some incredible work with these. Sorry to see them go.

Got to admire the F-35 though! One single program that has metastasized to the point where it bricks the defense establishments of not one but two of the world's greatest navies. If this were an enemy plot it would make more sense.

Mine's the one with a stiff, 4100 ton hull full of seamen in the pocket.

Have a pint. You have nailed it and gotten us to the heart of the problem.

Indeed these should be fit for the purpose of safeguarding our rights. At least in my chunk of the USA the coppers seem to believe they are only fit for purpose in covering themselves from liability.

So long as the primary goal of the police is to actually defend us and our rights, the ultimate outcome from pursuit of these objectives is the same.

Today though citizen's rights are on life support and the liability lawyer is king; hence any footage that increases liability- such as the murder of the Australian woman- is destined for the memory hole

Strange sample space

Lived and worked in around DC. No idea how one goes about getting a statistically relevant subset of 'DC'. The place is strange - extremely high end upper class neighborhoods adjacent to crack alleys... more law enforcement agencies with conflicting turf and objectives than any normal city... a daytime population vastly greater than nighttime... and so forth.

What I can tell you about cameras in the bedroom communities south of DC is that they've got a very strange failure mode. When more than a handful of cops are beating the crap out of an unarmed teenager - white or black - the BWC never seem to work. Strange, eh?

Why are racing boats so well equipped? "The difference between the men and the boys is the price of their toys." When I was a younger man I blew my $ on the boats and toys.

In my professional life Ive been intimately familiar with the bridges of many large, grey painted hulls. Working for the world's largest operator of fast planes, big ships, and violent men has given me a fair amount of hands-on at sea time.
