Connection of three "no-mirror display" monitors to one computer

Categories: Tech | Pubby Cash Received:  10

Experienced writers need big monitors. Although you can purchase one super big monitor with a size of 38" or above, the price is too high and it is not adaptable to different writing scenarios. For example, landscape is the default orientation of a monitor. When you are writing, there is a lot of unused space to the left and right of the word processing window. If you enlarge the text size to fill the entire window, the vertical view would be restricted. In this case, you may want to rotate the monitor and use in a portrait mode. If you only have one monitor, no matter the monitor is big or small, it is not practical to change back and forth between the landscape and portrait modes frequently. Thus, a secondary monitor that is oriented in a fixed portrait mode in addition to a primary landscape mode monitor would be very handy. Mac is relatively weak compared to Windows in this case, as its ability to extend screens to multiple monitors in an extended screen mode is restricted. If you don't have the latest mac products, it is likely that your mac system would support mirror display only. But mirror display is useless, since our purpose is to write, not to give presentations to people. With a Windows system, even for my $300 bucks old desktop computer, extended display mode can be easily set. I have one 27" monitor in landscape mode connected to a HDMI port, one 24" monitor in portrait mode connected to a VGA port, and the third 24" one in portrait mode connected to a USB 3.0 port. You will need to buy a USB 3.0 to HDMI port converter to add the third monitor. I've put the link below. I'm not in short of screen any more! ...  Read more

Differences between ranks and levels

Categories: Tech, Education | Pubby Cash Received:  10

People might be confused about the differences between ranks and levels. In this article, I will explain their concepts and why they need to be separated. Take academic ranks in the United States as an example. Academic ranks are the titles, relative importance and power of professors, researchers, and administrative personnel held in academia. The most common hierarchy for professors are three ranks: assistant professor, associate professor, and full professor. In some cases, chaired professor is also considered as a rank higher than regular full professor. In addition to ranks, the academia also has levels. Ranks are the titles printed on business cards to show people, while levels are different. Levels are mainly used internally for salary reference. In China, professors have 13 levels despite that the ranks are only 4. Their relationship between levels and ranks are as follows: Full Professor Level 1: Full professors who are academicians Level 2: Full professors who gain "Thousand Talent" titles and the like Level 3: Full professors who gain "Youth Thousand Talent" titles and the like Level 4: Full professors with no honorary titles Associate Professor Level 5, Level 6, Level 7 Assistant Professor Level 8, Level 9, Level 10 Technician Level 11, Level 12, Level 13 As far as I know, the base salary for a level 9 assistant professor is 5K while a level 4 full professor is 10K in China. In addition, levels sometimes can be used externally and printed on business cards. For example, a Level 2 Full Professorship is right below academicians and definitely worth bragging about. However, it will be weird if professors in lower ranks advertise their levels. Who cares an assistant professor is level 8, level 9, or level 10? The rank is what really matters. For the pubbies community, there are four ranks: member, community member, staff, and head staff. This resembles the real civilian world scenario that there is no need to introduce more ranks than needed. Otherwise, it will be hard for people to memorize and instantly see their differences. For example, military ranks are many, but how many people can tell major and captain, which rank is higher? Instead, the use of multiple levels within a certain rank is appropriate and efficient for internal promotions and salary raises. ...  Read more

Issuance of a Virtual Currency - Pubby Cash

Categories: Tech | Pubby Cash Received:  60

Pubby Cash is a virtual currency that is issued, managed, and controlled by GoPubby.com. Like other virtual currencies, Pubby Cash relies on a system of trust and is not issued by a banking regulatory authority. It derives its value based on a underlying mechanism: appreciation of article creation work by the fellow pubbies and appreciation of the moderation work loads by the moderators during the article publication processes. It is also backed by the underlying asset - the supreme quality of each article that is published on GoPubby.com and gains a number of likes. Pubby Cash can be used in circulation among the members of the online pubbies community who transact online for supporting the author of an article, for peer-to-peer payments, and for the purchase of virtual goods and services. I have several recommendations for the admin team to consider regarding the promotion of Pubby Cash : Ways of Gaining Pubby Cash : 1. Absolutely writing. As long as pubbies write, they should be awarded certain amount of Pubby Cash for appreciation of their devoted work and time. We could set up a base salary, say 40 weekly, as long as they are active and publish at least one article in a week. The base salary commensurate with experience. For pubbies in higher rank, it should be higher. 2. Gaining likes. Writing is not a the sole purpose. We need to award pubbies who write high-quality and in-depth articles. Undoubtedly, such articles will gain a number of likes and extra Pubby Cash should be given correspondingly as a bonus in addition to the base salary to those pubbies. 3. Helping moderation. Moderation as a moderator is a volunteering work for the pubbies' community. For pubbies who work temporarily as moderators should be awarded with extra Pubby Cash for compensation of their extra work and time devoted to maintaining the online community. 4. Peer-to-peer transfer. Other pubbies can transfer their Pubby Cash to you to show their support on one of your articles, or simply transfer to you for the online goods and services you could offer. 5. Exchange with real currency. If a pubby would like to support the running and growth of the website by donating real money, the website should respond with giving back the Pubby Cash at a fixed exchange ratio (say $1 USD = 100 Pubby Cash) as a sort of appreciation. Note that, this is economics as it comes to currency issues and is quite complicated. There should be no other uncontrollable means of gaining the Pubby Cash . Otherwise, inflation will occur for sure and the issuance of the currency will fail in the end. The value of Pubby Cash definitely lies in a fact that it can be used...  Read more

How to populate WTForms MultiCheckboxField

Categories: Tech | Pubby Cash Received:  10

It is very tricky to have a MulticheckboxField populated via WTForms with Flask. The field cannot be directly imported. You have to manually make a class using two other imported modules: widgets and SelectMultipleField! See code below: from flask_wtf import FlaskForm from wtforms import widgets, SelectMultipleField class MultiCheckboxField(SelectMultipleField): widget = widgets.ListWidget(prefix_label=False) option_widget = widgets.CheckboxInput() tag = [(0, 'General'), (1, 'Tech'), (2, 'Gaming'), (3, 'YouTube'), (4, 'Sports'), (5, 'Arts'), (6, 'News'), (7, 'Events'), (8, 'Education'), (9, 'Market')] class PostForm(FlaskForm): tags = MultiCheckboxField('Tags', choices=tag, coerce=int) ...  Read more

Can hashed password be decrypted?

Categories: Tech | Pubby Cash Received:  10

Account security is the most critical thing you need to consider when surfing the internet. Even the most 'secure' websites such as Equifax - an agency that store 800 millions of users' social security number information had a data breach and resulted in the most harm to users. (Check if you are affected by Equifax data breach here) Here are my recommendations when you surf the internet: Make at least three security levels of passwords for high-risk, medium-risk, low-risk websites. For high-risk website logins (such as online forums), only use the lowest security level password. For email logins (such as gmail, hotmail), use the medium security level password. For banking account logins, use the highest security level password. This way, the passwords are easily managed and memorized. Even if any of a high-risk website's database is breached and the password you used there is decrypted, your accounts with email and banking websites are still safe. Here is a question you may have: Is this website high-risk, medium-risk, or low-risk? As far as I know, this website uses the industry-grade and battle-tested bcrypt algorithm to securely hash and salt passwords to ensure extra level of account security. Even if the database is breached by hackers, the hashed passwords cannot be retrieved. This is different from some high-risk websites that passwords are not properly encrypted and administrators can see everything in their control panel. Therefore, I would classify this website as a medium-risk website. Therefore, do not use a password you used to access your banking account here. Also use a password that is different from your email's password, for a piece of mind. ...  Read more
