How dangerous is the coronavirus 2020

The coronavirus is extremely dangerous, and I suspect that the danger is currently being underplayed by the world medical community to minimize panic as we prepare for the worst.
Covid-19 is deadly, although fatality rates skyrocket for the elderly and those with compromised immune systems.

First and foremost, it is really important to know that as of today (February 17, 2020), there is still much we do not know about SARS-CoV-2 (i.e. the official name of the novel coronavirus) and COVID-19 (i.e. the official name of the disease caused by SARS-CoV-2). This uncertainty makes this question difficult to answer with a short or simple response.

However, epidemiologists and scientists from around the world are making rapid and significant real-time progress in understanding the nature of this novel coronavirus. Earlier today, a comprehensive report from the China CDC was released on over 70,000 individual cases in China, which included data for 99% of confirmed cases globally as of February 11th, 2020.

As I stated at the very beginning, there are still many unknowns out there. That is why there is no simple answer to the question of how dangerous this thing really is. Among others:

• There is no vaccine against COVID-19 (one that can be deployed safely at scale)
• We are still unsure about how contagious this is in people that are infected but asymptomatic
• We do not know how many people are infected, because (very likely) many people are infected and not yet identified for a variety of reasons
• We do not know exactly why infection and/or mortality rates for young people are so much lower
• We do not know how countries with less-developed healthcare systems will be able to cope with potential outbreaks
• SARS-CoV-2 will continue to mutate and evolve (although scientists aren’t that worried about this)
• It’s hard to predict the second-order effects (e.g. policy under/over-reaction, economic disruption, etc.)

What is the difference between DBMS and SQL

DBMS is a system and SQL is a language

DBMS (Database Management System)
A DBMS is a software for creating and managing databases. The DBMS provides users with a systematic way to create, retrieve, update and manage data. It is a middleware between the database which store all the data and the users or applications which need to interact with that stored database. A DBMS can limit what data the end user sees, as well as how that end user can view the data, providing many views of a single database schema

SQL (Structured Query Language)
SQL is the programming language which is used to access this DBMS and the database. It is the language in which you write the command regarding how and what to access in the database. In the figure above, API is what is SQL. The APP or the USER writes SQL commands which are processed by the DBMS

We use the DBMS system along with SQL for querying data in the database.

Now, for knowing the difference, you must understand one thing that is - in SQL we can see the data we want by asking a query, while DBMS optimizes the query and show us the data.

Let’s understand it with the example -

Suppose, you have a table that contains details of different persons such as name, age, gender, mobile number, address etc.

Now, if you want to see the mobile number of a person, you simply gave a query to DBMS, DBMS here starts working, catches query and finally, it will show you the mobile number of that person.

A DBMS (database management system) is a software system that allows you to store and retrieve data in an efficient and organized manner.

SQL is a formal language that allows you to communicate with many DBMS to insert, query, update, delete the content.

A large subset of the DBMS uses SQL, most notably almost all so-called "relational" DBMS. However, there are non-relational DBMS that use SQL (e.g. IDMS), and relational DBMS that don't use SQL (in particular the early versions of Ingres and Postgres)

Spiderman : Homeless Recent Buzz about the Exit of Spiderman Franchise from MCU

In a Sony statement to USA TODAY Tuesday night, the studio said the outstanding issue remained over the future involvement of Marvel President, and comic movie mastermind, Kevin Feige as producer in future Spider-man films.

 

 

So when the two companies agreed to share his rights in 2015, it felt like a homecoming -- Spider-Man was finally able to appear in films in the Marvel Universe.

Now played by Tom Holland, the character has appeared in five Marvel movies since that deal -- most recently this year's "Spider-Man: Far From Home."

 If Sony and Disney can't come to a deal, Spidey might not be in Marvel movies in the near future – but he probably wouldn't be anyway, unless for some reason he was supposed to be in "Black Widow" or "The Eternals," the MCU's next two films (which is highly doubtful). There's plenty of time to work stuff out.

Pulo Cinta Resort is an Indonesian Maldives

Pulo Cinta has a very unique historical story. Once upon a time during the Dutch colonial era, this island became a place of escape between the Prince of Gorontalo and the daughter of one of the Dutch traders. When that war broke out and was expelled from the local community. As a result their love is not condoned. They finally chose to break away and isolate the Pulo Cinta.

 

The Pulo Cinta natural tourism destination is perfect as a honeymoon spot for a new friend to get married, this Gorontalo island is located in Tomini Bay, Patoameme Village, Botumoito District, Boalemo Regency, Gorontalo Province, North Sulawesi. The distance is indeed quite far, if calculated travel from the city of Gorontalo which is about 115 kilometers or takes about 3 hours by road or any bay.

 

To visit Pulo Cinta, you have to take a flight to Jalaluddin Airport and continue the journey to Bolihutuo Beach. Only then will you board the ship for approximately 15 minutes to reach this Pulo Cinta.
 

Mini Africa Savanna in Wonderful Indonesia "Baluran National Park"

 Baluran National Park protects pasture animals such as buffalo, buffalo, deer, long-tailed monkey and long-tailed bird, peacock. You can see where they are grazing in the middle of the savanna. Every now and then, a herd of deer will cross your vehicle that is passing the road. This scene is often found in pastures like this. It is as if you will be taken far to jump to Africa with such a situation.

 

The area of ​​Baluran National Park is 25 thousand hectares. The location of Baluran National Park is included in Wonorejo village, Banyuputih sub-district, Situbondo district, East Java. Actually, this Baluran area is located on the border of Situbondo and Banyuwangi districts. Many people call the Baluran Situbondo National Park, others also call the Baluran Banyuwangi National Park. It's simple, because the location of this park is closer to Banyuwangi than Situbondo district.

Basics proxy setup for beginners

Normally you connect to the router by IP addresses with any telnet or SSH

client software (a simple text-mode telnet client is usually called telnet and

is distributed together with almost any OS). You can also use graphical

configuration tool for Windows (also can be run in Linux using Wine) called

Winbox. To get Winbox, connect to the router's IP address with a web

browser, and follow the link to download winbox.exe from the router.







MAC-telnet is used to connect to a router when there is no other way to

connect to it remotely if the router has no IP address or in case of

misconfigured firewall. MAC-telnet can only be used from the same

broadcast domain (so there should be no routers in between) as any of the

router's enabled interfaces (you can not connect to a disabled interface).

MAC-telnet program is a part of the Neighbor Viewer. Download it from

www.mikrotik.com, unpack both files contained in the archive to the same

directory, and run NeighborViewer.exe. A list of MikroTik routers working in

the same broadcast domain will be showed double-click the one you need to

connect to. Note that Winbox is also able to connect to routers by their MAC

addresses, and has the discovery tool built-in.





You can also connect to the router using a standard DB9 serial null-modem

cable from any PC. Default settings of the router's serial port are 9600 bits/s

(for RouterBOARD 500 series - 115200 bits/s), 8 data bits, 1 stop bit, no

parity, hardware (RTS/CTS) flow control. Use terminal emulation program

(like HyperTerminal or SecureCRT in Windows, or minicom in UNIX/Linux) to

connect to the router. The router will beep twice when booted up, and you

should see the login prompt shortly before that (check cabling and serial

port settings if you do not see anything in the terminal window).

What Role Did She Play in Miley-Liam Split? : January Jones

At least one tabloid has said Hemsworth was caught cheating with Eiza Gonzalez over the weekend, a Mexican singer/actress with whom he hooked up in Las Vegas.

But other reports have claimed tension between Liam and Miley for weeks, dating back to the latter's lewd Video Music Awards performance and continuing when Cyrus went naked for her "Wrecking Ball" video.

Then there's January Jones.

Rumors first surfaced in February that Liam swapped spit with the Mad Men actress at a Vanity Fair party, while an insider alleges the two have kept in contact ever since... especially dirty contact, that is!

More than one source says Hemsworth texted Jones that he wants to "f-ck" her, while Us Weekly quotes a friend of the star's who backs up this allegation and adds that "January thinks Liam is so sexy."

Liam Hemsworth was reportedly pursuing Mad Men’s January Jones, while his relationship with his 20-year-old fiancee crumbled in recent months.

A source told Us magazine that Jones thinks that The Hunger Games actor is very sexy.

Earlier this summer, Hemsworth had also sent the 35-year-old single mum, a graphic sexual message, which read the he wants to “**** her”.

The Mad Men star was earlier linked to Miley Cyrus’ former fiancee in February, when the two of them were spotted leaving West Hollywood hotspot, ‘Chateau Marmont,’ together.

A source had then revealed that Jones and Hemsworth were “all over each other” at a house party that night, though the 23-year-old actor denied the rumours.

Though a rep had recently hit out at claims Liam had been pursing the actress, insisting to GossipCop the rumours were "tabloid fiction," sources recently told Us Weekly the actor had once again been after her.  "January thinks Liam is so sexy," a source told Us Weekly, claiming the couple were "all over each other," on the infamous night out at the Chateau Marmont.

Hamming code

Hamming code
Richard Hamming invented at Bell Labs in 1950
Error detection mechanisms by adding a data word (D) with a code, usually a parity check bit (C).
The data stored in length D + C.
Known errors by analyzing the data and parity bits

# Data Bits	# Bit Paritas SEC	# Bit Paritas DEC
8	4	5
16	5	6
32	6	7
64	7	8
128	8	9
512	9	10

Parity check bits are placed with 2N formulation where
Each check bit (C) operates in every bit position data position number 1 in the column contains numbers
Data enter: 00111001 then change the data bits to 3 from 0 to 1 as its error.

how to get the data bits to 3 bits as there are errors?

  N = 0,1,2, ……, while the remaining bits of the data is. Then the exclusive-OR sum::

  C1 = D1 Å D2 Å D4 Å D5 Å D7

  C2 = D1 Å D3 Å D4 Å D6 Å D7

  C4 = D2 Å D3 Å D4 Å D8

  C8 = D5 Å D6 Å D7 Å D8

answer:

Enter data into the formulation of the parity check bits :

C1 = 1 Å 0 Å 1 Å 1 Å 0   = 1

C2 = 1 Å 0 Å 1 Å 1 Å 0   = 1

C4 = 0 Å 0 Å 1 Å 0   = 1

C8 = 1 Å 1 Å 0 Å 0   = 0

Now bit 3 having a data error : 00111101

C1 = 1 Å 0 Å 1 Å 1 Å 0   = 1

C2 = 1 Å 1 Å 1 Å 1 Å 0   = 0

C4 = 0 Å 1 Å 1 Å 0   = 0

C8 = 1 Å 1 Å 0 Å 0   = 0
