guardiangod··on IPv4 Waiting List
>it took me less than a week to understand enough to be able to set up an IPv6 LAN.

Don't mean to brag but it took the 12 year old me less than an afternoon (armed with a CISCO book) to understand IPv4 syntax/routing/ARP/DHCP + whatever and roll it out to my 2 computers lan.

The difficulty curve jump from IPv4 to IPv6 is humongous (IPv6 + ancillaries took me 2 days to setup in my home, and that's with a decade of IT experience.)

The issue is there are just so many officially right ways to do the same thing. Even assigning 'static' addresses has 3 official methods. Yes I get why there are so many of them (flexibility!) but it's a lot of stuff to learn and put together.

guardiangod··on Digging into Linux namespaces – part 1
Good article.

I mostly deal with the NET namespace (eg. 100+ VPN WAN source-base router + IDS lol) but I've never read an article that explore other namespaces in detail.

Let me perface this by saying thank you for being sincere and civil, because what I am about type might not be up to the standard you established.

I read that email and there's a serious tons of hand waving and 'dude, trust me.'

I am going to ignore "would be useful to a lot of people -- hundreds of millions of people who you may never know." There's no example use case of who the hundreds of millions of people might be, and how this proposal would benefit them. What are the benefits that the existing CG-NAT and ipv6 couldn't provide?

I am also going to ignore "one-line patches is almost risk-free." Sure if all the software in the world is only Linux/Windows/BSD TCP/IP stack and no one build anything on top of the stacks, then the patch would indeed be only 'one -line'.

What I really have a problem is 'simply include them in new releases of the various operating systems and router OS's that implement the Internet protocols.' I work for a _major_ hardware firewall company, and it is ridiculous the amount of effort we would put on our customers to upgrade their firmware. There are still hardware that run with 15 year old firmware (with all the accumulated CVEs). You are telling me it's easy to convince these people to upgrade their stuff? Are you serious??? 'People naturally upgrade their OS's every few years." Oh I guess we can ignore all the IoTs and middle-boxes on the interweb then.

"We have tested major routers, and none so far require software updates to enable most of these addresses." As mentioned I work for a firewall company. I just logged into a sample firewall under my control- yes the configuration is doable. But in enterprise, everything needs to be rigorously tested or else the sysadmin's not gonna touch it. The sysadmins are certainly not going to waste a few weeks of their lives testing things that might bring down their entire network, and would only benefit the select few who managed to grab ahold of the new IPs.

It's late at night and I don't want to continue. So here.

>0/8, 127/8, 224/4, 240/4

Why would anyone even bother. All the scripts and programs that were hardcoded to treat 127/8 as loopback and 0/8 as various default routes would need to be changed and more importantly, verified. You wouldn't want anything that's hardcode bind to, say, 127.48.47.218 as localhost to suddenly be routable from the internet.

I vaguely recall Cloudflare uses a huge chunk of 127/8 as internal loopback addresses for their edge servers. Without Cloudflare's support this proposal is DOA.

guardiangod··on Macron says France will build new nuclear energy reactors
>I mention this as a counterpoint to any 'If China's doing it, it must make sense' fallacy.

It makes sense if you realize

1. China pledges to peak carbon emission by 2030

2. Any increase in emission before 2030 will increase China's peak carbon allowance afterward.

3. Coal plants are cheap to build. Who cares if you only run them at 30% load factor for their entire lifespan.

4. Cap and trade between countries mean the carbon credit will worth a lot in the near future.

guardiangod··on When Facebook went down this week, traffic to news sites went up
I can believe that. My father often bugs me to buy things he saw advertised on Facebook ads. For older generation like him who spend a lot of time on Facebook, Facebook is a good avenue for non-Amazon sites to peddle their wares.
guardiangod··on Tesla’s headquarters will move to Austin
Maybe, although I would imagine Tesla's the premiere destination for fresh triple-star college graduates that don't mind taking a pay hit to work for Tesla (and burn out after 3 years.)

Or California's housing market is just too fucked. I think this is more plausible than the income tax too high theory.

>High earners pay an effective tax rate of > 50%.

Musk has not paid any tax because he hasn't cashed out any of his stock options yet. Some of his options will expire next year so he will pay tax then, but I am sure California will get the lion share of the tax revenue (as Musk lived in California up to 2021.)

The National Museum of Nature and Science in Ueno Park, Tokyo is my favorite place to visit in Tokyo. Everytime I am in Japan I'd find time to visit it. Its 630 yen entrance fee is a steal. I can spend a whole day in it, alongside school kids on field trip.

guardiangod··on Are SSDs More Reliable Than Hard Drives?
At work, I've been using hundreds of the top of the line SSD drives from a certain S company. The drives are used 100% from the start in 1U servers. The failure rate for them is higher than HD imo. The more worrying thing is that none of the drivess' SMART hinted their imminent failure. The drive would just die one morning, taking all the data with it.

Thank god for their 10 years warranty. I guess people like me is the reason why the S company lowered the warranty to 5 years for their next generation product.

guardiangod··on Art or heist? A Danish artist took $84k and sent a museum 2 blank canvases
While I don't know anything about art to disagree with you, I'd imagine people say the same thing no matter if it's 100, 500, or 2000 years ago.

I suspect the situation is the same with old appliances- only the Good Stuff survives the test of time.

guardiangod··on Xi Jinping’s War on Spontaneous Order
>Each targets an industry that seems to strip people of their agency and rob them of their dignity. Each seems to hijack healthy behavior with a set of short term incentives whose end results are self destructive and degrading.

>One does not wish to waste a child’s youth away on 18 hours of evening cram school a week, but to do otherwise is to risk falling behind. It is a classic arms race problem: no player can stop the game from the inside, even though all players would benefit from a cap on the game. An outside force is needed to halt the madness. Xi Jinping has decided to be that force.

I feel the author's logic is flawed here. In the previous paragraph, he wrote-

>Xi Jinping is not reigning in capitalism writ large; Beijing is not scrapping market mechanisms altogether. Semiconductor foundries, agricultural conglomerates, and Christmas light factories (to choose three examples of hundreds) have been untouched by Xi’s ‘common prosperity’ agenda. It is a very select slice of Chinese capitalism that is being “reigned in.”

You mean, working in 'agricultural conglomerates' or being factory workers making 50 RMB a day, is not 'hijack healthy behavior with a set of short term incentives whose end results are self destructive and degrading.'? (short term benefit for the factory owners to the detriment of the society and workers.)

The author took a winded way to try to distinguish the reason why certain industries are targeted, but really there is no need- the PRC literally tells you why themselves: 'Fictitious Economy' vs 'Real Economy' .

(https://www.reuters.com/world/china/chinas-cabinet-says-it-w...)

In Xi's eyes, anything that can't be physically grasp and control by the party belongs to 'Fictitious Economy' , hence the move to squash meal delivery (self-organized proto-union), k-pop/entertainment (voluntary idol worship), cram school (corruption and private source of education), and real estate (mass bubble speculation). Real Economy is output that the party can allocate and mobilize. The populace must lie down and accept whatever the party provides.

No need to invoke fancy Marxism philosophies.

guardiangod··on Hit me with a wrench all you want, I can’t tell you my password
I'd rather get hit by a wench than a wrench, if I am gonna get hit by something. Death by Snu Snu is preferable to death by blunt trauma- at least I get something out of it.
guardiangod··on Hit me with a wrench all you want, I can’t tell you my password
Sometimes I wonder if nerds find pleasure of finding loopholes in figure of speech and then feel all strangely superior about it.

"Haha I can't 'tell' you because the password can only be constructed from a specific series of hand gestures. Plot foiled!"

The attackers don't care if you can't verbally 'tell' them the password. With enough motivation, they will try anything to get it out of your head. A wench is just a tool to hasten that process, in certain scenarios. If you can't tell them, they will just hit you with a wrench until you tell them the exact way you use to reproduce what they need.

Edit: Thanks atatatat. Wrench, not wench.

guardiangod··on Jeff Bezos’ Blue Origin Sues NASA for a Moon Lander Contract
https://www.businessinsider.com/how-spacex-beat-blue-origin-...

Bezos said in a letter following the complaint that NASA risked compromising the mission by eliminating the element of "competition."

In response, the GAO pointed to NASA's limited funds for the mission. The group even took a stab at Blue Origin, saying NASA was not "required" to choose an applicant whose proposal NASA did not find attractive. In other words, NASA was not forced to take on two companies if it only found one company up to par.

Despite Bezos' offer to lower Blue Origin's $5.9 billion contract and take on $2 billion out-of-pocket, the GAO said NASA had found it "implausible" that the company could reduce its price without significantly changing its design.

Bezos said NASA had unfairly evaluated Blue Origin. For example, the company argued that it was not specified that the vehicle should be able to land in the dark. The GAO contended that NASA was not required to lay out all minute details, and Blue Origin should take into account the conditions on the moon or space itself- which is dark.

Blue Origin also raised issue with the fact that SpaceX received extra points for developing a system that focused on the health and safety of the crew- an objective that NASA had not made a requirement. The GAO said NASA had the freedom to choose which design function to prioritize.

guardiangod··on ‘A Form of Brainwashing’: China Remakes Hong Kong
1. The 'princess' of Huawei, Meng Wanzhou, was transferring flight in Canada when she was arrested on behalf of US.

2. China realizes this is a serious advantage and want to arrest foreign dissidents when they transfer flights in China. But no one transfers flight in any Chinese territories except in...Hong Kong, with its international airport.

3. China pressured the HK government to pass a security law that allows HK government to arrest anyone on behalf of PRC for extradition purposes, even for transferring flights.

4. The HK civilians revolted against the law for obvious reasons.

5. PRC flipped the table, suppressed HK, declared the Sino-British Joint Declaration to be invalid, and changed all the HK government's security officials to ones from the mainland. Oh, and the brainwashing starts.

Meanwhile, Meng Wanzhou is relaxing in her multimillion dollar mansion in Vancouver arguing Huawei has no ties to the PRC. roll eyes

guardiangod··on Starbase Factory Tour with Elon Musk [Part 1]
From the video and https://everydayastronaut.com/starbase-tour-and-interview-wi...

Musk overviewed his five step engineering process, which must be completed in order:

1. Make the requirements less dumb. The requirements are definitely dumb; it does not matter who gave them to you. He notes that it’s particularly dangerous if someone who is smart gives them the requirements, as one may not question the requirements enough. “Everyone’s wrong. No matter who you are, everyone is wrong some of the time.” He further notes that “all designs are wrong, it’s just a matter of how wrong.”

2. Try very hard to delete the part or process. If parts are not being added back into the design at least 10% of the time, not enough parts are being deleted. Musk noted that the bias tends to be very strongly toward “let’s add this part or process step in case we need it.” Additionally, each required part and process must come from a name, not a department, as a department cannot be asked why a requirement exists, but a person can.

3. Simplify and optimize the design. This is step three as the most common error of a smart engineer is to optimize something that should not exist.

4. Accelerate cycle time. Musk states “you’re moving too slowly, go faster! But don’t go faster until you’ve worked on the other three things first.”

5. Automate. An important part of this is to remove in-process testing after the problems have been diagnosed; if a product is reaching the end of a production line with a high acceptance rate, there is no need for in-process testing.

Additionally, Musk restated that he believes everyone should be a chief engineer. Engineers need to understand the system at a high level to understand when they are making a bad optimization. As an example, Musk noted that an order of magnitude more time has been spent reducing engine mass than reducing residual propellant, despite both being equally as important.

guardiangod··on Starbase Factory Tour with Elon Musk [Part 1]
It's good to see Elon Musk not to take personal credit on anything in the video. It shows that he is just a part of the team, and not the person who 'created' the rockets.

guardiangod··on Today we’re eating the winners of the 1948 Chicken of Tomorrow contest
A result from today's fast-grown chickens is the epidemic of 'woody' chicken breast.

https://holistickenko.com/woody-chicken-breast/

An increase in size and growth rate has caused the meat of the muscles to become harder and rigid in texture, giving a distinctive bulge to the breast and becoming known as woody breast chicken. The chicken, even when cooked well, is harder and chewy.

The white stripes that occur visually look like white lines running across the breast, tendons and thigh. A woody breast will feel firmer, like an incredibly tough muscle. When touching regular chicken breast the flesh is soft, you can press into it. Woody breast is simply firm to the touch, you cannot press into it (Kuttappan, V.A., et al., 2016). Occurrences of the woody chicken breast, as well as white stripes on chicken, have increased from around 1.4-8.7% in 2012 to a shocking 25.7-32.3% in 2015.
