Hey, Luke, is this article at all useful to you?
http://hackaday.com/2017/06/24/hackaday-prize-entry-a-3d-printer-management-...
It looks like something you could fairly easily implement in such a way as to potentially speed up laptop part printing... the way I envision it, you have one printer for each part, and it just spits out one after another into, eg, an empty Tide or Fresh Step box.
...or maybe I'm daydreaming. You tell me :)

i saw an ultimaker-2 just use the printhead to push parts off the printbed. it was even simpler than what that guy came up with. a heated bed one would assume you let it cool down first but it's so simple it's hardly worth there being a prize.

Correct me if I am wrong, but isn't simpler better for some things? no need to make things too complex right?
but I just learned what you have been trying to tell me for a while, with regard to how the amount of ram I have been asking for: 8gb isn't even needed.
I used lxtask manager and I looked up the difference between free and used memory. So... yeah... this will no doubt be the last time I care about needing more than 4gb of ram for the next 8 to 10 years. xD
yeah... my bad.

ah so you've not run 25 xterms, wicd-gtk, chromium with 20 tabs open, firefox with 200+, openscad, qemu _and_ vlc all simultaneously then :) that takes up 13 out of 16gb
no that's a developer mindset. for ordinary average person usage, libreoffice, one web browser maybe 3-5 tabs if that, and vlc: yes 8gb is total overkill.
one problem is that linux tends to use unused memory for cacheing. i have a vague recollection of it being used for file cacheing.

I cannot comprehend the necessity of having two hundred twenty browser tabs open, sum total... I rarely have need for one tenth of that.
But, then, I'm not a dev. Maybe for us mere mortals, there is some explanation? :P

information / history. search for one topic, explore five links (right-mouse tab) and not find what you want, then close 1/2 of them, open 5 more. within 5-10 minutes there are 20 tabs open on one topic.
then get another email message, and have something else to track down. but you're still in the middle of analysing the previous lot, which may take time. so leave those open.
repeat that process and after 2 months you easily have 200 or more tabs open.

Fair enough. Suggestion: power cycling your computer more than every few months might be good for it.
Mine gets rented-mule stubborn/slow after a couple /days/ like that. Not to mention, Mint has a bug with suspend/hibernate related to the wifi card -- I always have to unplug and replug it (I use an external card, the internal one is a burnt out POS and this Thinkpad still has an intact whitelist).
OK, enough typing from me for a while -- this laptop went for a tumble two days ago and the spacebar now works only if I freakin' stand on it. So I'm done, till I can get someone with actual dexterity to have a look at it.

I do end up power-cycling my computer; I tend not to leave it on when I put in a ventilation- and rain-proof bag to tke it somewhere.
When I power it up and start the browser, it offers to restat the tabs that were open when it lost control during the power down. I get to choose which ones. It's meant as a crash-recovery mechanism, but has other uses.
This is quite useful, and can lead to tabs accumulating longterm.
If I actually explicitly shut down the browser, it does not rememmber all the open tabs.
I could use more RAM. But my 32-bit system won't take more than 2GiB.

In my experience, there are few things in life slower than Chrome/Chromium after restoring a previous session...

I use firefox. It seems to do lazy restoration of tabs, which makes it somewhat more performant.
I've noticed that when it gets slow, doing killall firefox-esr and the restarting it does wonders for speed. Rumour has it that firefox never releases storage for a deleted tab, causing it to bloat.
I should try Chromium sometime. Chrome itself is no longer supported on 32-bit Linux.
I hate the way there aren't any cross-browser bookmarks. Another form of lock-in.

Indeed. I have significant experience of this as I operate the same way as Luke, so have hundreds of tabs in 50-odd windows at any one time.

My firefox gets noticeably slow after a few days, and extremely slow after 10 or 20 with lots of 10-second 'hangs'. I have spent some time trying to find out what is going on, collecting debug logs, and have determined that it is the garbage-collection action which makes it just do nothing for several seconds. Something is making memory horrible fragmented and/or just using it up steadily and not giving it back, and it just takes longer and longer to try and collect garbage. I have not yet determined which component is doing this. I can say that for most people (who have a lot of pages open) switching from adblock plus to ublock origin will save stonking amounts of memory and make things perform rather better, just because of the way they work.
I should try Chromium sometime. Chrome itself is no longer supported on 32-bit Linux.
I have not used chromium enough to determine if it better in this 'slowdown' regard.

If you are OK with remote bookmarks then you can use them from both chromium and firefox (e.g. google bookmarks), and it's quite easy to transfer them in either direction, but I don't know of a local, open, bookmark-store mechanism.

What about Import/Export to HTML? That's always worked well for me. Also, looking at Chromium, it seems to offer to import bookmarks from Firefox/Iceweasel (but not Icecat, from what I can tell). Likewise, Icecat seems to offer to import from Chromium (Bookmarks -> Show All Bookmarks -> Import and Backup -> Import Data from Another Browser).
However, I've tested the non-HTML import/export process using only a single bookmark, so perhaps it misbehaves if you have a lot of bookmarks/structure to transfer.
Does this not fulfill the task at hand?

I have, chromium uses lots of memory, just like FF. It has even worse troubles when it comes to more than 10 yabs. As for a slowdown over the course of several days, I've not tried it because of the above problems.

XBEL is an xml format for bookmarks. Elinks can use it, I don't know about FF or chromium.

Sure it does. History -> Restore Previous Session. Works perfectly for me, even if I explicitly shut down the browser. Or are you thinking of a different behavior than what I have in mind?

Actually, I also have one other thing to add, I might be wrong about my last message. it might not even use that much.
But if I am correct, processors are more important for linux laptops than crazy amounts of ram right?
unless, like you said they are developers.
Anyways I meant to send this directly to luke so we can drop this if you wish.

So not a total dev and not a total mortal. between worlds ;) ram 92% used always. firefox tor proxied and chromioum for bloddy cloudflare walled sites and for when firefox is clogged up with too many tabs :P. 16GB ram. struggled with 8gb for ages. a friend helped me out :) life saver having this much ram but now it looks like ive taken it for granted again! been having too many tabs = system slowdown problems this week. hmm time to kill some backlog and reduce project tabs.... my netbook is 2GB ram or was it 4gb...? i think its 2GB.... yea bit of a struggle on that. been using Enlightenment DE to save on ram.

This is common for me too. The tabs accumulate like this: 1. Search for "How to program in C" (or some other cool thing.) 2. Open first 15 tabs of links to sites advertising tutorials. 3. Open second list of 10 tabs for sites claiming to know the "Best" tutorial, book or other resource. 4. Go to the tabs of each website that advertised the "best" tutorial and open tabs for their recommendations. 5. Go to each tab and open tabs for every part of the tutorial. 6. Open tabs for every "This author recommends" page. 7. Open tabs for the links the authors link to and close the "This author recommends" pages. 8. Open tabs to expand all the tutorials and cool info you just got to.
This is how I waste memory in FF, others may differ.

I'm using 29 tabs right now after cleaning a couple. Libre Office and Rhythmbox open too. 4.3 out of 8 gigs free. Most of it is actually used memory and not cached. I open the links that I'm interested in and then leave them open until I'm done with them. You can easily get a lot of tabs, I have gone over 50 in some cases. Besides since I power off my computer every day at night I have it setup to reopen the tabs from last time I used it when I open it again. So the only escape is if I accidentally close them myself.
ah so you've not run 25 xterms, wicd-gtk, chromium with 20 tabs open, firefox with 200+, openscad, qemu _and_ vlc all simultaneously then :) that takes up 13 out of 16gb
no that's a developer mindset. for ordinary average person usage, libreoffice, one web browser maybe 3-5 tabs if that, and vlc: yes 8gb is total overkill.
I would say that even using a qemu with a winblows xp game on it while using an emulator or waterfox/icecat might almost use 4gb of ram but yeah... 8gb is insane for a normal user.
I see my folly now that I learned the meaning behind that show memory used by cache as free via lxtask.
well that's all.
