JackMcMackon AMD Zen 3/Ryzen 5000 announcement [video]

I don't disagree with you, but when was the last time you ever had to replace a stick of ram?

JackMcMackon AMD Zen 3/Ryzen 5000 announcement [video]

ECC is supported on the Pro series as well. My home server is running Ryzen 5 Pro 4650G (yay for integrated graphics) and Asrock B550M.

I went through the effort of using qvl memory, but actually testing ECC is a bit more difficult. While ECC is supported & active, memory errors are sadly not reported to the OS. I remember seeing a forum post somewhere of somebody overclocking/undervolting the ram to force errors, but I can't seem to find it right now. There's a fine line between stable, stable with recovered errors, and unstable.

JackMcMackon Adults with ADHD show decreased function in brain dopamine reward pathway (2010)

Extended work from home finally pushed me to get diagnosed (ASS + ADHD).

I'm now on 2x 10mg methylphenidate (ritalin). It has definitely helped, but after a few weeks I now feel habituated (is that the right word?). Unless something is on fire or past deadline I'm back to getting no work done. I do notice positive effects when combined with (too much) caffeine, but ideally I want to quit soft drinks (and I don't like coffee).

I think I will ask my gp to switch to extended release. I hope he's willing to help me find something that works best for me.

As a sidenote, I do with people could be clearer when describing their medication. Just say the active ingredient, dosage, and frequency. Brand names can differ in different countries.

For reference:

- Ritalin, Concerta = Methylphenidate

- Adderall = Amphetamine

- Dexedrine = Dextroamphetamine

- Vyvanse = Lisdexamfetamine

JackMcMackon Nvidia Unveils GeForce RTX 30 Series GPUs

Indeed it is. For those wondering, this (official) link has much more info (and the video), that the currently linked blog post.

JackMcMackon Nvidia Unveils GeForce RTX 30 Series GPUs

It's not mentioned in this announcement, was it confirmed somewhere in the past by Nvidia?

JackMcMackon Nvidia Unveils GeForce RTX 30 Series GPUs

True, the new generation offers better price/performance vs the previous generation.

Do note that the 3080 is still 2 weeks away (17 sept), 3090 24 sept, 3070 in October.

I would consider getting a non-founders edition though, in the past other brands have had better/more silent cooling for pretty much identical pricing.

Edit: While the 3090 (350W) is the only one requiring a 3 slot cooler, all 3 use the new 12 pin power connector. The 3080 founder edition power draw is still 320W, vs 220W for the 2080.

JackMcMackon Nvidia Unveils GeForce RTX 30 Series GPUs

As always, wait for the benchmarks before deciding to buy (or return). My guess is the performance improvements are the biggest for raytracing, which I personally don't care for. And let's not forget the huge power draw, requiring a new power connector and a 3 slot cooler.

8N manufacturing process is presumably Samsung, which will probably be beat by TSMC 7nm.

I'm holding out for RDNA2.

JackMcMackon OpenZFS Merged to FreeBSD

ZFS has feature flags [1]. If you're carefull not to do 'zpool upgrade' (as this commit message warns) unless you understand the consequences, you can switch between ZFS implementations.

[1] http://build.zfsonlinux.org/zfs-features.html

You can explicity create a pool with certain features disabled.

I'm going to try FreeNAS Core tonight.

JackMcMackon AngelCAD: Script-based 3D solid modeller

What IDE are you using for CadQuery? I really want to get into it, but I had trouble getting the default IDE up & running. And standalone python was too troublesome to code/visualize, the feedback loop got too long, especially compared to pure UI CAD such as Fusion360

JackMcMackon How to turn off Android TV's homescreen ads, 'staff picks'

I've run this for a while, but Kodi seems to be focused on the "old" way of having your UI run on your TV, whereas I would like to be able to browse through my content on my phone. Yes, Kore can do this, but it feels much more like an afterthought.

Prior to this I was running Windows (Vista I think) MCE with a dual channel analog cable capture card. That was truely the pinacle of home theater. Easy TV recording + easy local content.

Raspberry Pi + Kodi (+ NAS) feels underpowered, and a bit dated.

I haven't properly tested something like Plex.

NVidia Shield seems like it would do, but now ads might be coming...

Are modern smart tv's somewhat capable of local content browsing? Or is it like very basic file browsing?

JackMcMackon Show HN: Daily non-commercial blog posts which didn't reach HN's front page

Would you consider posting the individual blog posts in your rss feed? Use the original text, link through the original url, and maybe add a header or footer with HN link.

This way you don't have to leave your rss reader if you just want to read the article/post, which is kind of the point of the rss reader.

JackMcMackon Blameless post-mortems and a just culture (2012)

It means killing your org to live again.

This resonates with me.

I've experienced a few "agile transformations". They almost never stuck. The thing that mostly worked was creating teams with a majority of experienced agile devs, people willing to self improve and execute. And when the job is over, it all starts falling apart. Some team members might be believers now, they become disillusioned and leave. Some might have been good followers, but quickly conform to the old ways. You only have a temporary influence on a single team or project. You can't change a company's culture like that, without it hitting rock bottom first. This is very similar to overcoming addiction.

I've long wondered why NUMMI worked where others failed, something I believe is largely ignored in most literature: the factory closed. All the workers were out of a job for several weeks. And in comes Toyota with jobs for many workers, with the hopes of giving every single worker their job back.

JackMcMackon Living Without Atomic Clocks (2016)

The rubidium does not deplete (it's a closed system), but does settle on the glass. Supposedly you can heat the glass to turn all the rubidium into gas again, giving you theoretically infinite lifetime. I picked up a used PRS-10 on ebay for $250. It's a small but great oscillator, still made today. The manufacturer SRS claims 20 years lifetime, and mine has had 13 years of runtime, so I should be able to get 7 years out of it hopefully. The 11W1 DSub connector they used on the other hand is stupidly expensive.

Cesium oscillators on the other hand do deplete their cesium (by design), as mentioned by CuriousMarc in the video. The tube in his unit was probably replaced at least twice, at a cost of >80k. The high performance tubes fare even worse because they "burn" through their cesium at a 3x rate.

The 5071 successor by HP-Agilent-Symmetricom-Microsemi is the most frequently used COTS clock that contributes to UTC.

JackMcMackon DuckDuckGo is good enough for regular use

I love duckduckgo, but for some reason my home ip address (new-to-me but fixed) seems to be banned on at least one server, and I have to flush my dns cache often to be able to reach duckduckgo.com . I've tried reaching out to info@duckduckgo.com but only got a generic "thanks for the feedback response", and I don't have twitter. Is anyone from duckduckgo reading this?

JackMcMackon Why ZFS is not good at growing and reshaping pools, or shrinking them

The issue is not a loudly failing disk. If you get read errors, or if the disk is simply offline, it's easy to recalculate the data.

But what if you have silent data corruption: a single bit? Even if you have parity (raid5) or a duplicate (raid1), how do you know which part is correct, and which part to repair? Without checksums.

I've had to restore 1TB from Crashplan. They apparently had checksums in their software, and something like 10-15 files were damaged.

Without checksums, you simply don't know if your data is damaged, even on a single hard drive. ZFS gives you data integrity with checksums, and redundancy with mirrors or raid-z.

This is why a regular scrub is recommended, you verify the checksums and repair if possible.

JackMcMackon BorgBackup: Deduplicating Archiver

It's incredibly slow (backing up 1.5TB took more than a day), but the built-in support for PAR2 makes it worth it (for me).

Sadly, it seems like borg has no built-in support for any kind of redundancy [1]

JackMcMackon ZFS v0.8.2

Damn, I could've used this a few weeks ago. I moved my NAS from bare Ubuntu + ZoL to FreeNAS, and got stuck on a read-only pool because of unsupported features such as userobj_accounting (1). I had to zfs send/receive to external drives and back again to work around this, which was annoying, to say the least.

JackMcMackon Ask HN: How do you organize everything you want to do?

I can also recommend GTD, it was definitely an eye opener.

A few takeaways for me:

* There is no (need for) 1 list to rule them all. I'm using Google Inbox, Calendar, Keep, Post-it notes in the house on doors & walls, and a handwritten notebook for my day job.

* Inbox helped me organize a lot better. Snooze is great for getting an empty inbox. It used to have "snooze to someday" to incubate, but unfortunately that's not an option anymore. I still have 50+ items in there that I review a few times a year. I'm sad inbox is getting killed. Gmail has most of the functionality, but the UI is waaaay to busy.

* Keep is nice for simple lists. Grocery shopping has become a lot faster and easier. I will try to order the list so I can pick up everything in one pass. The kids & wife are joining the shopping trip? We can split up, see the list update instantly, and be done in half the time.

* GTD defines 5 phases: collect, process, organize, review, do. I wasn't used to having collect as a separate phase, but a lot of sites make this easy. Inbox has reminders, and a browser extension to save any page, Reddit has a save button, Inoreader has starred items. HN even has a favorite button, but does a very good job of hiding it. Seriously, I have to click on the post/comment age to favorite it?
