metildaa··on Zhaoxin KX-6000 CPUs Purportedly Match Intel's Core I5-7400 in Performance
A 7nm part won't be manufacturable outside TSMC or Samsung for years more, so this tech is really dependent on good relations with Taiwan or South Korea.

Scaleway has been hosting large scale SIP attacks for the past few years: https://badpackets.net/ongoing-large-scale-sip-attack-campai...
metildaa··on Ellen Pao: Our world is LGBTQIA. Your workplace should be too
There is a lot of hate from TERFs and religious groups towards the non-straight/non-cis community.

I think the corporatization of pride parades (like this article advocates for) is both harmful and helpful, insofar as its a positive for those of us in the Overton window (eg: gay people like myself) but it drowns out those that society still violently rejects (Trans, enby, pan, poly, etc) with corporate advertising rather than forcing society to improve.

Eh, Boeing has huge scale, but they havw a worse version of Amazon's recruiting problem. Terrible work environment for most employees (unless you like knuckledragger drivel), poor quality work by other teams being swept under the rug by managers, and large relocation/sign on bonuses being dangled in front of potential employees for year long commitments post-move.

I thought most seatbacks ran Linux?

For more critical applications, Boeing is using Ada on Linux atop AMD's new embedded CPUs, which have no closed firmware (to ensure auditability).

Sadly, Boeings culture rot has led to some poor design decisions recently.

metildaa··on Monzo Is Launching in the USA
I don't see any advantage of using Monzo over BECU (seems you've got fewer features). What is the value pitch here?

The US market is a fair bit different than the UK, there are a plethora of banks and credit unions to choose from.

Most US Credit Unions will give you a free account with free access to the co-op ATM network (every 7-Eleven, many gas stations, every credit union atm, etc) and reimburse $20 to $30 in 3rd party ATM fees per month. Live chat, card freeze, Zelle support, etc is built into BECU, Umpqua and presumably most CU/bank apps & websites.

metildaa··on Apple’s all-new iCloud for Windows app, now available in the Microsoft Store
Doubtful, Apple seems to want to keep iMessage as an iOS/MacOS exclusive as part of their moat to bring people into the full ecosystem.

iCloud was accessible through the web browser before this app was available.

metildaa··on How Did WeWork’s Adam Neumann Build a $47B Company?
Terrible experiences happen to me way more on the newer platforms I listed. People are literally crazy on those new platforms, I've had death threats (from a user which OfferUp never banned) and various other threats on those 3 platforms. Facebook, OfferUp and LetGo all ignored my complaints.

Craigslist over the past 2 years has had zero issues, I've interacted with fairly even keel 40+ year old people that are easy to work with. The "no lowballers, I know what I got" crowd has mostly departed Craigslist.

metildaa··on How Did WeWork’s Adam Neumann Build a $47B Company?
Craigslist seems to be dying as people use Facebook Marketplace, OfferUp and LetGo to buy used items. The end of the personals section combined with heavy advertising by the aforementioned new entrants is causing a slow user bleed from Craigslist.
metildaa··on Opera, Brave, Vivaldi to ignore Chrome's anti-ad-blocker changes
Note that this was done after two prior failed attempts to rewrite the CSS engine for multithread in C++: https://hacks.mozilla.org/2019/02/rewriting-a-browser-compon...

Its sad to lose DownThemAll and the plethora of othwr XUL extensions, but having performant multicore support is critical given the shift to having many cores (as single thread performance improvements become uncommon).

metildaa··on Opera, Brave, Vivaldi to ignore Chrome's anti-ad-blocker changes
WebKit/Blink is a mixed LGPL/BSD licensed project, with KHTML and other KDE developed parts being LGPL. Google likely can't keep most of their patches stripping support secret.
metildaa··on Microsoft deletes face recognition database
Silence is not consent, its a basic rule in the photography class I took. Microsoft seems to be going by the legal minimums, getting a dataset skewed by whoever is employed in that building (likely not terribly diverse).
metildaa··on Why the “Digital Ocean killed my company” incident scares the hell out of me
Notice the memory and file I/O, huge gulfs in performance. The focus of my comment though was about Amazon's restrictive leaky bucket CPU allocation scheme, you can burn through your allocation of high cpu use and then get throttled to 5% of peak use iirc for hours while this bucket refills. DO lets you use much more CPU comparatively.
metildaa··on Why the “Digital Ocean killed my company” incident scares the hell out of me
The CPU allocations on Lightsail are anemic compared to DO.
metildaa··on An update on last week's customer shutdown incident
Fyi, I'm planning to migrate off of DO due to the crummy payment options. With every other recurring service I can have a PayPal subscription, DO doesn't support PayPal properly though.

Also, your billing system is incredibly spammy (1 to 2 emails a day at times). The bills I get are always for partial months despite the VMs on the account running for a full month.

metildaa··on Huawei reassesses goal to be world’s bestselling smartphone vendor
China has a very distorted market, which has limited Alibaba and Tencent's ability to expand beyond China.

The lack of an app store is a problem unique to China that led to WeChat and similar becoming omnibus apps, doing many things moderately well. This isn't a problem in most other countries, as our govts don't block Google Play and FDroid.

metildaa··on AMD Not Conducting Further Technology Transfers of x86 IP to China JV
Hrm, citation? I'm just reiterating what I heard from an AMD employee that took me out for drinks. AMD needed the $200 million to survive and thought there were market segments they could not access in China, but a JV would not be encumbered in that manner.

By the time the JV's chips would be in volume production, it would be 2 generations behind, thus not eating AMD's existing Chinese customer base.

Edit: Nice un-noted edit...

metildaa··on AMD Not Conducting Further Technology Transfers of x86 IP to China JV
Sure, but China has a less competent industrial espionage than Israel, who has failed to steal the secrets of TSMC's or Samsungs processes for Intel (leaving them trapped on 14nm with a really broken 10nm node in development).

As it turns out, bleeding edge silicon lithography is massively expensive, and the cost to build newer processes balloons every generation. Most of the secrets of each process aren't generalizable between vendors (like how transplanting a design from TSMC 14nm to Global Foundries 14nm would take a fair bit of engineering work).

metildaa··on AMD Not Conducting Further Technology Transfers of x86 IP to China JV
Zen 2 is designed for a 7nm process, which limits its production to TSMC or Samsung. There is nowhere to build AMD's newer chips in China (unlike 14nm Ryzen), stopping them from using the tariff bypass they did through this JV. This lack of bleeding edge fabs in China is unlikely to change soon.

MIPS is a product of Wave Designs in California. We're years away from a non-western influenced CPU being commercially available.

VPNs and firewalls can't help when the cellular basestation is the issue. How would you prevent a malicious LTE client fron running these exploits?

Telcom security is a mess, but the frontline gear is usually the saving grace of the network.

> I want to see a modern one, if possible with free software GPU support like for the Mali

The Mali drivers that were just mainlined last month aren't necessarily feature complete like Intel, Via or AMD GPU drivers. Mali is licensed from ARM, which would be a showstopper for US embargoed companies.

> Which is exactly why I want to see MIPS64 that can do all that without hardware acceleration - and much more with it.

If MIPS64 were competitive on price, we would have a plethora of tablets & boards based on it. Currently, dated Mips 24k cores are a $0.10 afterthought that is used to boot and initialize the dedicated ASICs. We've started seeing ARM cores eat the router market though, they're likely delivering more performance for that $0.10.

The cellular network being totally insecure is much worse than passive surveillance. Calls and texts can be rerouted and altered in transit, and mobile identities (eg: your SIM) can be impersonated on a whim.
metildaa··on Huawei reassesses goal to be world’s bestselling smartphone vendor
AMD did something very similar as a way to bypass tariffs in China (license their 1st gen 14nm Ryzen IP to a JV), but they've brought a ton of scrutiny to this loophole from both the USA & China, plus this trick won't work for Ryzen 2 since no 7nm fabs exist in China (and none are on the horizon).

This is a pretty weak rebuttal, the MT7621 based board you cite has two MIPS 24k CPUs, straight out of 2005: https://wikidevi.com/wiki/MIPS_24K

All of the MT7621"s speed is from ASICs that accelerate NAT & WPA2, without that silicon external to the CPU, any kind of crypto would slowly chug along.

More competitive offerings like the OrangePi PC Plus ($19) and FriendlyARM boards based on Allwinner chips offer much nore performance for the dollar, but these are literally foriegn IP blocks Allwinner licensed, glued together and sent off to a 45n or 28nm fab to have manufactured. Most of the work Allwinner did for these chips was on a trashcan ready, buggy board support package.

The telcos really want to have Huawei in the running, as their presence on RFPs causes a 30% price drop in competitors bids.

Problem is, really basic maintenance tasks like updating OpenSSL aren't happening on Huawei's existing cellular basestations, leaving cell networks vulnerable to anyone who can be bothered to look up a CVE and run the provided demo exploit code. Hard to maintain a network you can't secure :c

Huawei has no 7nm fab available that will turn a blind eye to pirate ARM chips (since their ARM license was revoked), and it is unlikely any new 7nm fabs will be built in China soon. See my other comment: https://news.ycombinator.com/item?id=20077587
metildaa··on Huawei reassesses goal to be world’s bestselling smartphone vendor
China already has an (uncompetitive) alternative stack, covering silicon to operating system.

The problem is with building a competitive stack, Huawei can't get access to a 7nm fab in China, nor is their talent skilled in working with the limitations of said newer process, which kneecaps their ability to build chips competitive with Qualcomm and Apple.

Huawei can build 7nm chips at TSMC, but due to their ARM license revocation and Qualcomm's inability to license them cellular patents under FRAND during this dispute, TSMC is unlikely to fab IP infringing chips.

If TSMC were to fab these chips, their other 7nm clients (primarily Apple, followed by ARM licensees Qualcomm & AMD (which uses ARM TrustZone)) would all be in an uproar as ARM would likely prohibit the use of their designs at TSMC fabs.

Wrt China building their own 7nm fab, it is very unlikely they will get it off the ground in the next few years. Only TSMC & Samsung have succeeded in this, Intel, Global Foundries (formerly AMD) and many others have spent tens of billions and half a decade trying to build better than 14nm processes to no avail.
