If you are an early user, it should be very I am used to receiving blog or website content updates through RSS Reader (RSS reader). The earliest I used Google Readerbut most of the users of this service after the end of the service in 2013 Go to Feedly Inoreader or other services with similar functions. I still like to receive new articles via RSS, but now there are not many readers to choose from, and many blogs do not open full-text RSS feeds. If you want to read the full content, you still have to go back to the original website.

Recently I plan to leave Feedly to find an RSS reader that can be used on Mac. Although Feedly has Mac application it has fallen into disrepair. The focus is still on its own web version. The famous “Reeder 5” seems to be the best choice, but it needs to be paid for (Mac version $9.99, iOS version $4.99). There is no trial and I am not sure whether it can meet my own habits. According to the evaluation, it is also a pretty good reader.

was later found “NetNewsWire“, which is a free, open source RSS reader, provides free download of Mac, iPhone, and iPad applications a few days The experience of using it is quite satisfactory, and Feedly will also be officially decommissioned from the browser. If you are looking for an RSS reader that works on Mac or iOS, NetNewsWire is my recommended choice.

NetNewsWire allows users to receive updates on their favorite blogs or news sites, and can also manage their reading more clearly. This also means that there is no need to search for content updates from the browser, bookmarks or refresh, as long as If the website provides an RSS Feed, you can add it to the NetNewsWire subscription and automatically receive notifications.

NetNewsWire also mentioned that if you are still using social networking sites such as Facebook to receive news, those advertisements, algorithms, user tracking, and misinformation are all annoying. You can choose to use NetNewsWire to receive news from trusted and reliable sources. Information updates may help to reduce information anxiety for modern people with information explosions.

When NetNewsWire is opened for the first time, there will be some preset subscription sources, allowing users to test related functions and operation methods. The leftmost side will list today’s updated content, unread or marked content, and Shows the number of subscribed articles. You can see the website logo, article title, preview and time in the middle. After you click it, you can read the content directly on the right (of course, some websites do not open full-text RSS feed output, so you need to return to the website to read).

STEP 3

Select and delete the subscription source on the left, click “+” at the top and select “New Web Feed” to start Join the website you want to subscribe to. After entering the URL of the information source (for example) NetNewsWire will grab the RSS Feed. Some websites do not have the RSS function or may be due to errors If it is set, an error will occur if the application cannot find its RSS link.

Users can also add folders to manage different types of RSS feeds.

For example, if I add the free resource network community to the NetNewsWire subscription, new articles will be displayed in the app. Click to read the article content directly and also mark the article Star, share in other ways, etc.

STEP 4

After opening the preferences, select the account source to be added from “Accounts“. NetNewsWire also supports several common and commonly used RSS services including Feedbin, Feedly, BazQux, Inoreader, NewsBlur, The Old Reader and FreshRSS.

What’s even better is that if you want to synchronize the same subscription list on Mac, iPhone and iPad, you can also turn on the “iCloud” function, which can synchronize the subscription status with iOS and Mac devices.

After I turned on iCloud as an account, I disabled the “On My Mac” function, so there is no need to store the subscription source on the Mac, because it is saved To iCloud, you can synchronize updates in the iPhone app.

STEP 5

In addition, NetNewsWire defaults to refresh the RSS feed every hour. You can also shorten the time interval to 30 minutes or 10 minutes, which can be faster , Get information in real time.

For example, browsers are used to opening many tabs, and each time they respond to messages, they have to jump to the instant messaging page. Mac users may choose to download unofficial ones before. Messenger for Mac、Caprine or Goofy App can temporarily solve similar problems.

Speaking of Virtual private network(Virtual Private Network, referred to as VPN) What do you think of?Many people may say that websites can be browsed normally in countries or environments where the Internet is restricted, but “over the wall” is only one of its functions. In fact, VPNs also have features such as improving browsing security, encrypting connections, or blocking malicious websites. ,E.g Cloudflare WARP Both privacy enhancement and network acceleration can improve security in an open wireless network. In addition, some people will use VPN as a “springboard”, pretending to connect from other countries, such as browsing regionally restricted websites or cross-region shopping, it is very useful. Some products are in different countries. Different pricing and currencies will be used.

For example, I don’t usually need to use a VPN. Sometimes I just need to register an account across regions, or buy, subscribe to products, or pay. I don’t want to buy another month of VPN service for this, but I worry about downloading unclear software. May increase the risk in the use process, you can consider more well-known brands, they usually also provide free trials or free programs.

This article will introduce “FlyVPN“It can be regarded as a big brand of VPN service. I paid to use it in 2016. It just happened that recently I needed to cross the region to a European country. It happened to provide the connection node I wanted for free.FlyVPN supports common platforms like Windows, macOS, Linux, and mobile apps are also available for download on iOS and Android, This part can be regarded as the standard equipment of VPN service! Some will also develop extensions for different browsers, but this service does not seem to exist, but it does not affect the use.

FlyVPN free trial plan provides about 40 connection nodes, Including the United States, China, Hong Kong, Japan, South Korea, Taiwan, Thailand, Turkey, India, Vietnam, Kazakhstan, Cambodia, Portugal, Belgium, and Denmark. There are restrictions on usage time and traffic (free usage will have one every day Hours limit), but newly registered users can use the mobile phone without limitation for three days, and the connection speed is fairly fast.There is no need to pre-set the credit card or payment method when registering, and there is no need to worry about deductions at the end of the trial, This part is fairly safe in operation.

If users want to pay to subscribe to the FlyVPN service, the website provides plans for one month, six months, one year to up to two years. The longer the subscription time, the cheaper the unit price. It supports various payment methods such as credit cards, bank cards, PayPal, MyCard, Alipay or virtual currency, etc. The paid plan will be able to use more than 500 server nodes, without traffic and operating time restrictions, it seems to be a fairly cost-effective choice.

Can go to the registration page).

Enter the email and verification code when registering, and then click “get verification code“, FlyVPN will send a set of verification codes to the mailbox, copy and paste the verification code and set the account password, and check the agreement to the terms of use to register for free.

A notification will also pop up in the upper right corner (if it is Windows, it should be in the lower right corner), telling the user that the node is currently connected, and the download and upload speed of the network. After connecting, all network connections will go through the VPN The server just arrived at the destination,If you don’t want to use it, remember to go offline, otherwise all traffic will still go through the FlyVPN server.
