thirsty sword lesbians does it and even goes so far as to make it one of three ways to get XP that the party has available to them and so at the end of each session where nobody had used a safety tool one of my friends would joke "okay now i'll say every slur i know in alphabetical order so someone can safety rtool me and we all get XP" and it was funny every time. poorly thought out implementation of an obviously good impulse

i understand why people do it and it's obviously well intentioned but i think mechanically incentivizing the use of safety tools is a silly practice because it then mechanically incentivizes doing things you know will result in safety tools being used. and of course i don't think anyone would actually follow that to its logical conclusion and do that but it is what that kind of mechanization inadvertently makes into 'optimal play' which is imo a bit of an oversight

Help exists! / Hjelp finnes! - 🇬🇧There is help out there but the question is are you open to receive it? I know I wasn’t for many years bc I felt that no one could help me, but that is not true, trust me I learned that the hard way 😉 I also learned that I have to help myself I have to be responsible for my own health, learnings and happiness, Ofc it may take time but it’s the key to everything. the beauty of it is that it is so many ways to get the support you need, in tools, from self love, from others, but you must dare to experiment to find what works for you! 😊 - - Det er hjelp å få men spørsmålet er jo er du åpen til å ta i mot hjelpen? Personlig så slet jeg lenge med det at jeg trudde at ingen kunne hjelpe meg, men det er ikke sant det finnes metoder og hjelp der ute for oss alle. Jeg skjønte det at jeg måtte ta ansvar for min egen læring, helse og egen lykke, ja det kan ta tid å finne ut av men det krever at man tillater degselv å eksperimentere får å finne ut hva som passer for deg, om det er redskaper, andre mennesker, deg selv, osv, det er opp til deg! 😊 ——— This image was made for the book #DetErOrdBakBokstavene written by @infoliten and @sjova.

R 4.0 install Rtools, solve warning: Rtools is required to build R packages but is not currently installed

STEP 1 DOWNLOAD RTOOLS

Download link: https://cran.r-project.org/bin/windows/Rtools/rtools40.html

STEP 2 INSTALL RTOOLS

Just click all steps as default

STEP 3 CONFIGURE PATH

There are 2 ways to do it, I only use the first one then solve the problem. If you can't solve problem by using first option, then use the second.

OPTION 1

Open RStudio, and run code as follow:

writeLines('PATH="${RTOOLS40_HOME}\usr\bin;${PATH}"', con = "~/.Renviron")

If there is no error messenge appeared, then close and open Rstudio again.

Once there is error messenge, jump to OPTION 2

OPTION 2

open a text editor, copy PATH="${RTOOLS40_HOME}\usr\bin;${PATH}" into and save file under RStudio's working directory.

To get working directory: Run getwd() in Rstudio

Then change file name to .Renviron

(don't leave .txt at the end)

If error popup like: you have to name a file name, then do as follow:

change file name to a.txt

open Windows Powershell by shift + right click file directory

run code: ren a.txt .Renviron

if there is no error appeared, then open file and double check if code was correct

CONFIGURE CONT...

Once close and open Rstudio again, run code to check if configuration has been correctly set.

Sys.which("make")

If there is messenge like: "C:\rtools40\usr\bin\make.exe" then you have configur rtools succesffuly

CHIA SẺ QUY TRÌNH TRIỂN KHAI SEO CƠ BẢN

1. Nghiên cứu từ khóa:

a. Nếu biết từ khóa chính của mình thì dùng ahrefs nghiên cứu đối thủ, lấy kết quả từ khóa của 5 đối thủ đầu tiên gộp lại và bỏ trùng lặp. Tiếp đ��n lấy những từ khóa có lượng tìm kiếm cao cho tiếp vào Keywordtool.io lấy ra khoảng 100 từ rồi gộp tiếp và bảng từ khóa tổng, loại trùng lặp tiếp. (Ahrefs và Keywordtool nên dùng mua chung cho rẻ, có thể mua của Rtool, Trần Lâm, Khắc Anh,…)

b. Nếu chưa biết từ khóa ngành thì bỏ ít tiền chạy adwords, sau đó lấy gợi ý từ khóa trong Google Consule, lấy xong mang vào ahrefs lặp lại bước a bên trên.

2. Phân loại từ khóa:

a. Sau khi có bảng tổng hợp từ khóa ta đi phân loại từ khóa. Có 3 loại từ khóa cần chia ra như sau:

i. Từ khóa CHÍNH: Cạnh tranh cao, từ khóa chung chung top của ngành

ii. Từ khóa HÀNH ĐỘNG: Là các từ khóa dài nhưng có tỷ lệ chuyển đổi cao

iii. Từ khóa THÔNG TIN: Thông tin, tìm hiểu, hỏi đáp

b. Bước tiếp theo sau khi có bảng phân nhóm từ khóa, ta tiến hành lên cấu trúc nội dung: H1, H2, H3,…

c. Tiếp theo gửi cho bên content viết theo cấu trúc đã lên, hoặc có thể thuê.

d. Lên sitemap cho website theo từng landing page hoặc, có thể chi tiết tới nội dung

i. VD: https://domain.com/em-nhi-chua-co-nguoi-yeu-> landing page cho từ khóa chính “Em Nhi chưa có người yêu”

ii. VD danh mục: https://domain.com/nhi-2k1

iii. VD bài viết, blog: https://domain.com/bai-viet-cua-nhi-co-duoc-khong-a (Bài viết này trong danh mục “NHI 2K1” nhưng khi lên web phải dùng Breadcrumb điều hướng, link để ngắn gọn, không cần chứa danh mục trong link bài chi tiết).

3. Thiết kế website:

a. Yêu cầu code thiết kế web theo sitemap dựng ở bước trên, nhớ web lên phải chặn index.

4. Lên nội dung cho website:

a. Nội dung chuẩn SEO hay không thì cứ theo Yoast SEO hoặc Rank Math (Lưu ý: Link out ra phải nguồn có uy tín và cùng ngành nghề, không out ra những site kem chất lượng). Nội dung có link nội bộ điều hướng thế nào, từ khóa ra sao anh chị tự tìm hiểu ạ.

b. Lên đầy đủ nội dung, check lại onpage, có thể dùng SEO Quake, Web Developer, Google Speed Insight, Uptopz của Diệp Nguyễn…

c. Tới đây với cài Google Analytics, Google Search Console và cho website index, anh chị nhớ Submit sitemap trong Google Console.

d. Fix lỗi trong Google Consule nếu có thông báo.

5. OFF SITE:

a. Việc đầu tiên và quan trọng là phải xây dựng lực cho trang chủ trước, sau 2 tháng mới đi xây dựng cho các landing page. Lưu ý quan trọng: Nên điều hướng link nội bộ từ trang chủ về landing page trong thời gian đầu đẩy lực cho trang chủ. Vậy đẩy lực bằng cách nào?

i. Tạo Google My Business site, site maps cho Brand

ii. Social Entity cho Brand: Có thể dùng 300 Social hay 600 Social cho brand cũng được, dùng tool index cho chế độ drip feed trong vòng 30 ngày: Dùng LARindex, linklicious, expressindexer, elite indexer, link processors, Instant link index (toàn bản mất phí). Miễn phí em sẽ có Tip cho bài khác ạ :D . Anh chị lưu ý Social Entity đồng nhất thông tin của website, thông tin trùng với Google my Business, site maps, logo, số đt, email (nên dùng email domain), tất cả thông tin này phải xuất hiện trên website chính. Có thể mua của các anh SEO Mũ Cối, GTV, Đặng Lê Nam, Phan Tài,…

iii. Social Entity Auhor: ít nhất là 1 Author cho web cá nhận, nên dùng nhiều cho công ty có quy mô. Mỗi Author nên làm khoảng 20 social chính, thông tin Author trên các Social đồng nhất và ghi rõ cơ quan hoặc web đang làm việc (web đang seo)

iv. IFTTT:Dùng IFTTT kết hợp RSS FEED cho auto tin trên site chính ra khoảng 20 Brand Social và từ Brand Social Auto Link ra Author Social.

1. LƯU Ý QUAN TRỌNG: tất cả các link Social Brand và Author đều phải được index thì mới có kết quả tốt. BẮT BUỘC phải khai báo Schema những Social chính của Brand và của Author.

v. Google Entity Stacking: Cái này hỗ trợ SEO Map, SEO local nhiều hơn, đẩy lực từ các tài nguyên có sẵn từ Google: Google Drive Folder, Google Doc, Google Sheet, Youtube, Slides, My Map, Drawing, Form, G-site, Blogspot. Có thể dùng IFTTT kể kết nối các tài nguyên.

vi. Làm đồng thời thông cáo báo chí, càng nhiều báo càng tốt, không lo chênh lệch các chỉ số như anh Diệp Nguyễn nói. Site mới anh chị cứ đi dạng Full URL hoặc Brand. Thương hiệu hay sản phẩm nào mới ra mắt đều phải có bài thông cáo báo chí hết. Có thể mua báo của Phong Nguyễn, Hường Link Báo, Hiếu Cao,… Còn 300 Backlink báo Global của anh Diệp nếu nội dung khác nhau trên các site báo thì nên mua từ tháng thứ 2 hoặc 3, nếu dạng Press Release thì nên dùng cho tháng thứ 3 hoặc 4 và từ khóa thương hiệu, hoặc từ khóa chung chung.

vii. Xây dựng và chăm sóc các web 2.0, cái này tốn tiền content, mỗi tuần nên lên 1-2 bài, làm khoảng 10 đến 20 site đa nền tảng. Nếu có điều kiện hơn thì nuôi PBN.

viii. Làm đều các việc trên trong 3 tháng, sang tháng thứ 4 mới đi link về landing page, lúc này có thể mua thêm guest post, PBN, Link báo cho các từ khóa cần seo, nên làm từ dễ tới khó và dùng các bài viết trên web 2.0 sau khi chăm nó được 3 tháng trở lên.

ix. Dùng SEO Autopilot đi link cho các Social Entity và Brand và Author, Tiếp đò Dùng GSA đi link cho tầng 2 hoặc tầng 3 của SEO Autopilot. Dùng 2 Tool này anh chị phải tốn tiền mua: Proxy, Tool Build Content (mỗi tool 1 bộ), Email, Capcha (càng nhiều càng tốt), Indexer (như đã nói ở trên).

x. Từ các tháng thứ 5, thứ 6, tùy vào độ phát triển của đối thủ và của từ khóa, mình có thể bơm thêm link, tăng cường các bài viết dạng silo, link wheel, internal link hợp lý trên các landing page để Rank từ khóa.

6. Trên đây là các bước cơ bản mà em đã thực hiện, để viết chi tiết hơn khéo phải trên 10 trang A4. Anh chị đọc xong cho em xin ý kiến ạ. Cảm ơn anh chị đã đọc tới đây ạ.

"Nguồn đi copy về, các em đọc có chọn lọc lấy cái hay. ví dụ như cái entity author khá hay."

---

Đến phút chót mới ngỡ ra mình ảo tưởng vch.

Nhưng mà ít ra ông anh sếp cũng quan tâm. Thế mới thấy ông ý nhanh. :))

This most likely means you don't have Rtools installed. If that's not the problem try passing showOutput=TRUE to get more diagnostics.

I've been looking all over the net for about two weeks now trying to find a solution to this problem. Application Launch Failure The application 'PowerPoint' could not be launched because of a shared library error: '4<Microsoft PowerPoint><OpenGLLibrary><CFMPriv_AGL>' All of my Microsoft Office X apps work except for PowerPoint. I've found about 50 (I was going to say 1000) suggestions on how to fix the problem. Lots of guesses. No one knows what is going on and no one has an answer. The above text in quotes varies from problem to problem, BUT, it's always a shared library error. I've tried every suggestion I've found. Nothing makes any difference. To the best of my knowledge, this problem occured not long after I 'updated' some system protection from Apple/Mac and/or 'updated' Office from Microsoft. Will all of the pundits please chime in? Let's think this out and stop guessing. Gary

7 Common Digital Marketing Challenges and how to overcome them

Marketing is about connecting with your audience. Digital marking is a form of marketing that targets people online. Many businesses can use digital marketing to their advantage with channels such as search engines, social media, email and websites to connect with existing and future customers. Even though these channels are available there are new technologies approaches that can be used that can impact and create new challenges for marketing and sales groups. In 2019 a research study was conducted by Altimeter to determine what the current state of digital marketing looks like. In this study we explore what the seven most common digital marketing challenges may be.

1. 55% of marketers find that trying to find people with the right skills and qualifications to hire to join their team is proving difficult. For business to overcome this challenge they should define what work has to be done and find the right combination of teams and use of agency partners. An approach like this must be extensive and logical to deliver its superior outcomes.

2. 54% of marketers find that gauging innovation across the whole organisation is a top challenge.

Business need to find the right experts, best practices, training methods and digital resources to meet their objectives and deliver their highest marking ROI.

3. 50% of businesses create a digital marketing strategy. With technology rapidly changing marketers struggle to develop a clear strategy for what they must accomplish and how it will run across the business.

Businesses need a digital marketing strategy that suits their requirements. An effective strategy targets customer opportunity, assessing the capabilities, finding and prioritizing gaps and establish a strategy to turn customer insight into growth.

4. 47% of digital marketers find having the digital rtools valuable easier to attribute the business impacts to their marketing actions but struggle to demonstrate how analytics and insights can deliver something useful and impact their different growth levers.

Businesses need to gather their data from multiple digital sources and create a measurements system that can be used across the whole organisation and provide both qualitative and quantative insights.

5. Purchasing the right software is one of the top challenges for 46% of growth leaders. There are more than 7,000 different vendors that can process technology platforms to decrypt the data and tool needed to improve the businesses marketing.

Finding technology advisors who can use platform evaluations and make recommendations for feature upgrades should be a common need

6. 46% of marketers find getting increased investment and support from leadership is always a challenge.

Partnering with industry leading researches and digital experts can help the business find investors through a combination of industry analogues, data and in-depth knowledge.

7. Customers want to be recognized for their digital interactions and expect a cohesive and positive experience at every touchpoint. 33% of marketers find that creating and delivering a personalized experience a challenge.

Tailoring content, customizing user profiles and personalization has become easier to do so from new data sources and martech tools. Multi-factor customer segments can be used in personalization schemes involving B2B and B2B2C.

Misdirection

Magic Tricks that rely on misdirection!

2 card monte

3 card monte

Two guys in the white van (fake speakers trick)

Misdirection: Con Artist/Social Engineer makes target pay attention to the wrong thing and calms down their interest/alertness/arousal about the right thing. So you don't notice the right thing, only the wrong thing.

The art of keeping attention where you want it, so that you can put things in place without people knowing

Kevin Mitnick Attack

US Hacker, caught by japanese physicist

Used TCP/IP (TCP is higher IP is lower on the networking stack)

He's never confirmed that he did it

Attack:

Christmas 1994: "Shim-San"

TCP has one setup (handshake), connection live and comms, tear down

uses a seq number to keep packets in order

Session hijack: persuade the server to send the next packet to you and increment the seq number

for the OG request, it will time out because it will have an invalid seq num

Shim-san set up all his machines with RTools in UNIX, so that instead of always logging in, if you login from a trusted computer, then you can log in to any computer

If you compromise one machine, all machines are compromised

The Authentication in the R Protocol the machines were using used the IP address of the packet (src addr). Not really that secure because anyone can 'spoof' the src addr

R Protocol works on a TCP Level, but in order to be authed, you need to have a valid TCP connection setup.

Attacker (1.2.3.4): hi im 1.1.1.1

Target (2.2.2.2): ok hello 1.1.1.1

Target 2 (1.1.1.1): lolwot? reset

Target (2.2.2.2): reset

Attacker (1.2.3.4): waiting...timeout

Mitnick DOS'd target 2 and found a simple pattern in the sequence numbers -> increased by 128,000 each time.

Mitnick (1.2.3.4): DOS Target 2 creating a bunch of half open connections, Target 2 cannot accept any more connections

Target 2 (1.1.1.1): Bruh all these connections tho, ok no more

Mitnick (1.2.3.4): Hello (2.2.2.2) im (1.1.1.1) with this initial seq num and SYN

Target 1 (2.2.2.2): Hello (1.1.1.1) SYNACK with your seq num incremented and my seq num

Target 2 (1.1.1.1): Still busy...doesn't reply

MitNick (1.2.3.4): ACK (2.2.2.2) with my seq num incremented and your seq num + 128,000

Connection successful

Mitnick (1.2.3.4): Open RHOST File -> Allow every computer

Really important thing, this attack happened at christmas. Everyone is naturally mis-directed at this time.

When a system is in chaos, naturally we turn down the security settings and open up our exposure to risk. Risk is invisible, and no one will notice until something goes wrong.

More Social Engineering:

krak des chevaliers

Crusades era castle, held by the Knights Templar, had an outer ring and inner ring. Eventually outer ring fell by the Ottomans, templars retreated to the more formidible inner ring. Ottomans forged a letter from the head of the Templars telling them to surrender and the templars believed them.

Tutorial Notes:

ECB:

has repetition, same input leads to the same output

each block is independently encrypted

CBC:

encrypt the block and XOR it with the previous block

this means that a change to one block will change all remaning blocks

has no repetition and affects all future blocks

CTR:

doesn't affect any future block

Has nonce and counter which means that theres no repeition in the ecrypted text

check:

affecting future blocks

repetition

if affecting future block: CBC

if repetition in the ciphertext: ECB

Else (no repetition and not affecting future blocks): CTR

Perfect forward secrecy:

If you intercept all traffic for one session it doesn't help you any other future sessions
