WHO has reported at least 6 Vaccines going human trials, 3 of them Chinese, one is Russian, i suppose there is one American and one from UK. I even read some news about Peru using something from Llamas...

The race for a vaccine and better drugs to treat started in January, and they guestimated at least a year, but given the urgency i'd say they really made progress, it also helped the sharing of info which tends to go against big pharma interests.

Originally the idea behind isolation was for people to contain the virus until proper medicine was available, but many couldn't just remain isolated, helping the virus spread. The virus exploited human weakness to socialize, and has claimed nearly a million lives.

It definitely isn't lasting forever, or actually it may, but won't harm much when everyone gets immune by surviving it or getting the vaccine.

BTW there is a new nasty virus in China but it spreads from ticks biting humans it seams; troublesome for those handling animals i guess.

There is also reason to believe the virus was spreading even before Dec 2019, but Wuhan had the place able to detect it.

I was doing some research about how to use strong password which can be easily remember and I find a site which was said to randomly generate strong password.
My question is, should i trust the password generate from this site?
Is it save from brute force?

Note : I'm going to use with an offline computer

I dont know if i posted this thread in the right section if not please let me know.

You should download a proper password manager like KeepassXC (Free and Open Source) and let that generate your passwords. Never trust online generators, or proprietary software for that matter.

How do you know such an online generator isn't saving it for some private database or giving it to some agency?

My current internet connection is such a piece of garbage that i have gone back to offline games. Currently I'm playing Dungeon Keeper, since i never played it back in the day. I tend to like sand box games like the Sims 3 or "simulated" stuff like Kerbal Space Program. Recently i also found entertaining a free game called Endless Sky, which is yet another space trader like 2d game.
1304  Other / Off-topic / Re: Chinese products are junk on: August 09, 2020, 09:30:48 AM
The range of quality for Chinese products goes from cheap and disposable up to expensive indistinguishable from certain brands in terms of quality. Obviously, the cheaper stuff tends to be known more, since its what people aims for more often than not.

The reason is simple: They do manufacture for the expensive brands as well. So they CAN, and DO sell expensive quality things as well. Well, usually the expensive stuff is still cheaper than the quality brands anyway, but not as cheap as the really cheap stuff.

Ideally people would have a choice, but often do not, unless they buy direct and already know what they are buying.

There are also shameless merchants that buy the cheap things and try to sell it like the good quality brands (and often imitating the brand name too).

The truth is, it depends in what you buy. Just because its made in China doesn't mean that is automatically crap.

For example i have a cheap Huawei cdma "feature" (not smart) phone from 2007, i just wanted something basic back then. Surprisingly, it still works, with the original battery which is mad. Sure its charge doesn't hold long nowdays, but its disturbingly working even after 13 whole years. I remember having a couple of similar Siemens phones die on me like 2~3 years after being in use. I also has some Samsung i bought after that didn't last even 4 years, one day it went off to never turn back on again, just like the Siemens. Of course i know people whose smartphones weren't so great. Also i have some Phillips led lamps that have been going for a decade with nearly daily 8hrs+ continuous use, while the more recent Chinese led bulbs i had already one die on my under a year. Of course the Phillips was like $60 while the Chinese isn't even $3.

I know for a fact that in the 70ies-80ies Japan had a similar reputation, but unlike China they never wanted to make cheap disposable stuff and currently their products are among the best. And yet what they sell in Japan is on a whole different level, than the same thing they sell abroad. It is also possible to see certain Chinese things sold in China being better than the (nearly) same thing exported.

Most of the "expensive" brands literally manufacture things abroad, often China, or Vietnam or similar poor country where they can pay miserable wages. In theory branded products have a better quality control, but that doesn't mean you cannot find a simillar quality product from a Chinese brand.

Well it should be fixed. Carefully plan when how to execute it, and do it. No need to leave baggage to the future generations; "i won't be here" is no excuse for leaving unfixed things that could be fixed.

Or, do you think those Roman bridge builders though their creation should crumble by the time they died? Many are still in use today, couple thousand years later... And that was before modern construction techniques and materials (they did invent concrete, more or less).

There is time to plan it, but there is no reason to ignore it. Same as the quantum resistant changes.
1306  Bitcoin / Bitcoin Discussion / Re: Beirut explosion - Lesson to learn from this. on: August 09, 2020, 07:44:38 AM
When you make a cold wallet, by writing 12 words in a paper with your own hands, i have mentioned many times that you should make a copy (again with your own hands, no electricity) so that you have two papers with the same 12 words you store securely at two physically separate locations.

Please stop the talk about private key because while the seed words internally recreate it, you are not directly handling a private key, nor should you ever do it due to the security implications. Never handle private keys directly, stick to the 12 words, and protect them well.

As for the Beirut case, sadly it is yet another case of State bureaucracy. Apparently these hazardous materials have been stored for many years and across at least 4 administrations. Of course, some official designated that specific area for all flammable materials, so it was all conveniently places together (fireworks, nitrate ammonia, etc). All it took was one lousy wielding or spark igniting some fume or who knows.

You'd be surprised at how common this is in many countries: State bureaucracy plus less than stellar practices. You people in the "first" world wouldn't even know how often we gamble our lives everyday just by getting born in the wrong place. I'm sure most people in Lebanon didn't even know such dangerous things were concentrated there.

So it happens they had this port for everything related to agriculture, all that grain stored, and no doubt this nitrate was meant for fertilizing purposes. Ironically this country has had plenty to worry about with its neighbor having the largest military power of the region plus insurgency stirring things all the time.

On the afternoon of 4 August 2020, two explosions occurred at the port of the city of Beirut, the capital of Lebanon. The extremely powerful second blast resulted in at least 158 deaths, 6,000 injuries, US$10–15 billion in property damage and an estimated 300,000 people made homeless.[1] The blast has been linked to about 2,750 tonnes (3,030 short tons; 2,710 long tons) of ammonium nitrate – equivalent to around 1.2 kt – that had been confiscated by the Lebanese government from the abandoned ship MV Rhosus and stored in the port without proper safety measures for six years.

Under normal circumstances, I see no reason to stock up on goods for a long time.

ALWAYS stock on non perishable goods, especially when there is no reason, so that you have it when the reason comes and avoid the rush of everybody else trying to procure the same things at outrageous prices or simply going out of stock.

By the time the reason comes, it will be too late. Never count on disasters to send you an advance notice. Yes, same as keeping your savings in USD rather than BTC, once it falls, you won't have a chance to exchange, you are already poor, thank your politicians.
1308  Local / Español (Spanish) / Re: $11,000... por fin rompimos esa barrera. on: August 08, 2020, 07:34:28 PM
Realmente el ATH es 20k si, lo de los 11k, pues bueno el año pasado hubo de eso. Está bonito (para los trader) pero nada de que emocionarse. Yo espero que se estabilice, otros que solo hacen trading necesitan que no, pero el mercado habla no los deseos individuales. Aunque no le llamaría entropía, pero está bien... Es simplemente que el valor de algo es percibido de manera distinta por la subjetividad de las personas, y por supuesto cambia en todo momento, la correlación (o puja) de ambos resulta en el precio.

Hay que prestar atención al valor del dólar, que en cualquier momento puede caer.
1309  Local / Español (Spanish) / Re: Opinion de Plan de Trump para Latino America on: August 08, 2020, 07:26:49 PM
Yo opino que aunque lo intente no podrá competir en precios, solo china sabe explotar los recursos y el tiempo al máximo y desgraciadamente la gente en latinoamérica es algo peresosa y no tan enfocada como los asiaticos. Como ejemplo los chinos cuando hacen huelga aceleran la producción, en américa simplemente dejan de trabajar.

Así que no se que tan buena sea esta medida. No creo que le funcione del todo.

Ese es un viejo cuento de Japón, no de China. Las culturas son distintas. No quita el argumento, claro.

Trump lo que necesitaría es el país con el sueldo mas miserable del mundo: Venezuela. Pero, la relación binacional está en uno de los puntos mas bajos de la historia, obviamente.

El resto de los países, tradicionalmente por ejemplo México les ha fabricado productos siempre que les duró su acuerdo comercial, que acaba de ser modificado y no precisamente en favor de Mexico.

Pienso que realmente es demagogia. El objetivo de Trump era volver al pasado al cual America (USA) se niega a volver, un pasado en el que producía. Ya no produce tanto porque sencillamente es mas rentable en otros países, donde se puede pagar menos para hacer lo mismo (y es la verdadera razón por la cual EEUU había movido toda su producción a China). Trump piensa que a fuerza de decretos y leyes proteccionistas, puede de alguna forma revertir esto, pero sencillamente le es imposible.

Consideren que por su edad, si vivió y conoció su país cuando producía mas que ahora, pues su economía se movió mas hacia el sector servicios, finanzas, etc. Ahora este tipo de personas se negará a admitir que todo cambió, hasta que sencillamente se van.

No exista tal cosa como una "guerra comercial" entre EEUU y China, existe la guerra de Trump, que es como la guerra de Maduro: Una ficción solo termina con la salida del cargo. La globalización es un resultado de la sociedad moderna, ya no se puede volver al tiempo en que las distancias eran insalvables y lo que no se hacía localmente sencillamente no existía.

Las comunicaciones hoy mas que nunca permiten hacerlo, solo quedan las barreras artificiales impuestas por los políticos. Irónicamente dichas barreras tienden a ser mucho mas severas contra las personas que contra las mercancías; son las paradojas de la globalización.

Y China no duerme, China tiene toda la intención de consolidarse en latinoamérica, tan pronto la situación de Venezuela cambie, por ejemplo. Venezuela tiene algunas maquilas, pero eso solo sería el comienzo que se mantiene en suspenso hasta tanto cambie la política local. Pero ellos son pacientes, esto ocurrirá, no en vano la deuda de Venezuela mas grande es con China (igual que la de EEUU).

Cada vez parece mas difícil que Trump repita, y si lo hace, serán solo 4 años mas. Afortunadamente, existen países donde los gobernantes no ostentan cargos vitalicios. Sin duda que EEUU volverá a lo que ha venido haciendo antes de Trump, sus políticas no durarán ni son tan populares como se piensa, ni siquiera dentro del grupo y partido que lo apoya.

De Trump no se debe esperar nada. Es mejor mirar a otra parte, incluso China, que se ve encaminada a desplazar la hegemonía americana.
1310  Local / Español (Spanish) / Re: La propuesta de valor del Bitcoin on: August 08, 2020, 07:04:11 PM
Bitcoin tal como está, funciona bien para pagos de un día para otro. Por ejemplo al momento actual, solo se necesitan 3 sat/B para que una transferencia se confirme en 1 día. Usualmente 1 sat/B (el mínimo) es mas que suficiente y para una transferencia promedio en mi caso eso representa unos 300 satoshis, de manera que ahora en momentos de congestión, bastaría con usar unos 900 satoshis.

La mayor parte del problema es en las carteras, que alegremente intentan hacer pagos de confirmación en una hora (o menos) y por efecto dominó, siempre que aumenta el tráfico se disparan las comisiones (por culpa de esas carteras, no de Bitcoin). Pero si se dan cuenta, la mayor parte del problema está en la cartera y la actitud de los usuarios.

Si necesitas "pagos instantáneos", puedes usar LN o algún altcoin, pero es opcional. Realisticamente hablando, Bitcoin puede hacer pagos "instántaneos" (10 min) sin ayuda de nada, pero cuando la red no está saturada por ejemplo por el abuso de algunos exchanges en momentos de volatilidad.

En un mundo ideal, no se usan exchanges, ya que se paga y se recibe pago en Bitcoin.

El tema del aumento al tamaño de bloque nosotros por acá le decimos "correr la arruga". No es una solución escalable y sencillamente es postponer lo inevitable a costa del aumento del tráfico, cosa que justamente se desea evitar.

Fíjense como ethereum constantemente enfrenta los mismos problemas, sencillamente tiene demasiado tráfico, en el caso de ellos, porque todo el mundo usa su blockchain para otras cosas gracias a los fulanos contratos inteligentes tienen la red sobrecargada (todo el que se invente un token, primero piensa en ellos).

Y lo que nosotros decimos es que el problema no es técnico, es humano. Con el tiempo, las aguas volverán a su cauce y todo funcionará correctamente. De hecho siempre lo ha hecho, pero la gente se lleva impresiones erróneas por desconocimiento; y para que lo entiendan mejor, no vean Bitcoin como medio de pagos instantáneos, véanlo como medio de pago de un día para otro y notarán cuan perfecto es.

Lo que se escribió en el whitepaper se hará realidad en el futuro cuando todo madure, sin necesidad de hacer cambios. Yo de hecho entiendo a la gente que piensa en lo innecesario que fue todo el asunto de LN, aunque no comparto todos sus argumentos pues segwit si me parece útil con o sin LN, y las direcciones bech32 ahorran dinero en comisiones de envío.

Damn dude.

This kid is going to get one hefty sentence. This is identity theft of an extremely serious degree, and could even be considered an act of terrorism considering he exfilitrated the personal data of presidents, ex presidents and members of congress.

There is a 100% chance that they are going to make an example of this kid, I'm expecting 5-10 years in prison at the very least.

I guess the $1 million bounty Justin Sun put on his head was enough to send people on an epic man(boy?)hunt.

Let's see if he can social engineer his way out of jail.

These millennials, how could they be so stupid? This kind of thing, you cannot absolutely go against your own country, even with the infamous "7 proxy" whatever stupid media culture portrays.

If they were, i don't know Russians, Chinese, Iranians or North Koreans, places where America can't reach, i would get it. But Americans against Americans?; well what can i say. Just breaching an American company server is bad enough, lets ignore the many affected individuals all right and powerful enough to permanently ruin this kid's life... Its suicidal, i don't think the common black hat is dumb enough for this.

And on top of that there was that juicy bounty, which would lure the others. Yup, not gonna end good. Lets see how many more are involved, so in the end it was a bunch of kids for the lulz. Unless they recruit him or something, which i bet some of them dream of, but i doubt it its not that stage in history anymore. The State has plenty of skilled employees already, even the military, for "cyber" operations. Those romantic days of "do a great hack and get hired" are long gone.

5 to 10 years really sounds small for America. Unless he does a lot of negotiation giving names, etc. I remember how Manning got busted for trusting Lamo who in turn was another idiot turned informant...

If they did this against China, Wechat, TikTok whatever, they would probably be getting a medal in the Whitehouse instead (and recruitment probably) Tongue
1312  Local / Mercado y Economía / Re: Pido consejo para vender bitcoin on: August 02, 2020, 03:50:19 PM
Para ahorro a largo plazo, es necesario crear y usar una cartera en frío. Está fuera del alcance de malhechores informáticos. Solo puedes depositar, pero no sacar sin regenerar la cartera y eso solo se hace con las 12 palabras anotadas en un papel a mano.

Por ejemplo inicias la PC con un Linux desde un pendrive, ahí le pones Electrum y creas la cartera, anotas las palabras (a mano) y te copias digitalmente todas las direcciones de esa cartera que quieras, para que puedas "depositar". Luego, así sin mas, sin guardar ni nada, se apaga la PC para que todo quede borrado.

La cartera existe, y le puedes hacer depósitos, pero no sacarle nada.

Incluso puedes vigilarla con Electrum sin "abrirla", solo ver lo que tiene y lo que le entra. Para abrirla tienes que regenerarla, y eso se debe hacer de forma similar a como la creastes. Eso se hace solo en casos muy excepcionales.

Aunque alguno te va decir que compres una hardware wallet y la guardes, eso es muy pero muy malo. Las memorias flash pierden lo almacenado con el pasar de los años; y esas carteras necesariamente te hacen anotar las palabras a mano también, de manera que es una inversión perdida.

La utilidad de una hardware wallet, es no usar una pc o un teléfono como cartera. Es útil con pequeñas cantidades, para hacer compras; sobretodo cuando no se sabe trabajar con un sistema operativo mas seguro. No debe emplearse para almacenamiento a largo plazo.

Técnicamente hablando, las "carteras" no almacenan moneda, pero lo dejo simplificado así para los demás.

Total desacuerdo. ¿Comprar dólares? ¡Compra bitcoin!

Tu piensas que los dólares son "seguros" y ahí está tu gran error. No se te pasa por la mente que se repita exactamente lo mismo que nos hicieron con el bolívar, porque ellos son de alguna forma inmunes a la emisión ilimitada de dinero sin respaldo, porque su economía es mas grande y diversa, etc.

Pero lo que no te das cuenta es que eso simplemente les da mayor capacidad de maniobra, mas no es infinita. El dólar puede caer, y si cae, habrás perdido lo que ahorrastes.

Y a la hora de comprar algo, se cambia por bolívares y ya. Y si sales del país, los bitcoin están ahí, siempre. No hay riesgo que te atraquen o te matraqueen. Ni zelle, ni paypal, ni skrill, ni andar pariendo abrir cuentas por ahí o buscar que te den una pedazo de tarjeta crédito/débito en el país que pisas. Bitcoin funciona siempre, en todas partes, sin bancos, y no hay que andar enviándolo o cargándolo encima, está ahí; el dólar no.

Puede que el dólar no desplome, pero si desploma, es tarde para ti, ya perdistes. ¿Vas a confiar en los políticos otra vez? ¿Tu no ves a Trump repartiendo real a todo el mundo, con dinero que no existe en ninguna parte? Hizo exactamente lo mismo que Maduro: Emitió dinero sin respaldo. Los gringos son mas pilas, muchos agarraron ese cheque de $1200 y derechito pa' bitcoin. Deberías agarrar consejo. De hecho los que lo hicieron, compraron a 9k y hoy está en 11k, ya se ganaron 2k con esa movida.

Los que se sigan fiando del dinero fiat, están condenados a repetir la misma desgracia, tarde o temprano.

Kaboomracks hasta $25. Eso es lo que revenden acá en $100. Ese kaboomracks tiene usuario en el foro, obviamente en inglés y está en Telegram. Lo de $25 es incluso de antes del halving, todo este tiempo han revendido por acá con esa diferencia de precio, semanas antes del halving a $400 pero afuera en $25.

Y claro en cierto grupo de Telegram los revendedores quejándose de que no se debe divulgar el precio real cuando criptonoticias hizo el artículo ya con varias semanas de atraso (como dije, desde antes del halving estaban a $25)

Pero siempre te dirán que se paga flete y nacionalización (aunque no nacionalicen), así que el mejorcito te vende en $90, solo el triple de caro...

Y no es todo, hay quienes venden afuera por piezas como "dañado", y resulta que de ahí sacan tarjetas buenas y arman maquinas completas. Esas venden en paleta tarjetas, cases, controladoras y ventiladores. Así que es posible hasta menos de $25 por ebay. Los que tienen capital pueden hacer esas compras tranquilamente containers con paletas de S9 desarmados al costo del peso, de tanta granja desmantelada en donde la electricidad es mas cara.

Entonces ya tienes la respuesta, pero puesto aquí te saldrá mas caro. Buena suerte...

I only play some old skool games like red alert and dungeon keeper. Sometimes I also play some Pokerstars but nowadays I use most of time the IPhone and IPad for gaming.

I started to play Dungeon Keeper recently, quite surprised. Reviews mention that the games made after it weren't so good, specifically DK2. I never played either and had that hole in my gaming history. Well, not anymore.

Excuse me, time to send a prisoner to the torture chamber, and back to prison before it "breaks". Rinse and repeat enough, and even the "Lord of the Land" becomes your subject; good.

Back when games gave you actual educational values...

Its no wonder the ratings of that game are thru the roof. Sure the graphics are dated (even with alt r) but Dosbox runs it happily anywhere.

It had to do with a certain Japanese web novel whose main character everyone was commenting was inspired in DK. Puzzled, i went for it. Now all makes sense...

Consider buying from alibaba, you'd probably make a bigger cut and lower those prices. US prices aren't great for things like bags. All they really make is weapons, and only for their closest "allies" and internal. The rest is outsourced anyway.

There is this documentary, about Chinese new rich elite purchasing furniture from the US which in turn imports all the raw materials from China. Well, at least the Chinese elite helped paid those US wages the US common folk can't afford (and buy cheap Chinese "disposable" furniture instead).

I hate that exchanges, some pools and other online wallets don't let you choose the transfer fee. Most people can wait a day. Currently a 4 sat/B fee would take a day, it was 1.3 a few days ago. The current "next block" needs about 158 sat/B, i rarely ever need anything within the next block; but everyone uses those wallets with the fee guestimation built in, and then blame it on Bitcoin...

If you can wait a day, then use the recommended fee for 1 day confirmation. If you can wait more than a day, go with 1 sat/B.
