Apple May Launch 16-inch MacBook Pro by End of Year 25 Jun 2019, 3:29 pm

There have been rumors of a new 16-inch laptop coming from Apple floating around for quite a while. A new report suggests the system is real and will ship in the next few months, with September the most likely launch frame.

According to IHS Markit, the new laptop will have a unique display size (16-inch) and a new resolution (3072×1920), up from 2880×1800 used in Apple’s Retina-class MacBook Pro up until now. It’s a fairly modest bump, as far as total pixel count, stepping up from 5.184MP to 5.898MP. Production figures are expected to be around 250K/month based on IHS’ projections.


There’s no sign of an OLED panel as was previously implied — some PC manufacturers are moving to OLEDs on certain high-end laptops, but Apple may not want to make this jump yet. OLED panels are certain to have different power consumption figures than typical LCDs and will tend to respond better if kept in dark mode to reduce overall power consumption (unlike LCDs, OLEDs don’t use backlights and consume markedly less power when displaying dark content).

There’s no word of any additional improvements to the system. Issues like the T2 security processor USB bug (specifically, the T2 processor causing audio glitches when working with the USB bus) apparently are still occurring as of late May and have yet to be resolved. It is not known if Apple intends to fix this problem in hardware or software, or with a future version of MacOS.

Apple is also expected to offer an update on the 13.3-inch MacBook Pro and Retina MacBook Air, though less is known about these updates. Supposedly there will be a 32GB RAM option offered on the 13.3-inch MacBook Pro. No other upgrades have been specifically mentioned and there’s no news of any updates for the 12-inch, single-port MacBook.

We have been recommending caution when considering Apple hardware and continue to do so. Apple’s laptops, in particular, have been beset by a host of ongoing issues the past few years, with multiple audio issues, a shipping UEFI on the Core i9 models last year that led to dramatic throttling (fixed post-market) and ongoing reported problems with displays and keyboards that have led to expensive repairs or expensive repair programs once Apple was willing to acknowledge the issues. Apple also recently recalled its 15-inch MacBook Pro from 2015, saying that the batteries in these systems may pose a fire risk.

There is a reason, in other words, to be concerned about the overall quality level of Apple products in ways that didn’t seem quite so prevalent a few years ago. Obviously, everyone has their own experiences on topics like this — run an article on reliability, and chances are good you’ll have at least two people with completely opposite experiences with the same brand over multiple products and years of life.

But the sheer number of complaints about Apple — and the way these complaints have risen at a time when the company has been aggressively trying to boost revenue from its Services division (which sells AppleCare) — have not painted a pretty picture of what Apple’s financial goals with some of its design decisions might be. The fact that the company is now on the fourth revision of a problematic keyboard design and still won’t certify that it’s actually solved the problem is emblematic of the larger issues here.

Microsoft’s Dual-Screen Surface Could Launch in 2020, Run Android Apps 25 Jun 2019, 3:28 pm

The dream of the mythical Microsoft Courier may not be dead after all. Microsoft is reportedly working on a dual-screen tablet device that could debut as soon as next year. The device will allegedly have dual 9-inch displays with a 4:3 aspect ratio and support for running Android apps. 

According to IHS Markit, Microsoft calls the device “Centaurus” internally, but it will be part of the Surface brand when it launches. In addition to the dual screens, Centaurus will have Intel’s latest 10nm Lakefield system-on-a-chip and could support either LTE or 5G connectivity. 

Centaurus won’t run the same Windows you’ve known and tolerated on touchscreen devices in the past. Centaurus will allegedly run Microsoft’s new Windows Core OS (WCOS), a slimmer version of Windows for Chromebook-like laptops and tablets. WCOS will serve as the base for Windows across various devices, but it will lack aging technology like Win32 apps and legacy shell interfaces. One thing Centaurus will apparently offer is Android app support. 

Microsoft has struggled to get developers to use its Universal Windows Platform, in large part because these apps only run on Windows 10. A developer who wants to support the greatest number of users would just write a traditional Win32 app instead. Centaurus could potentially sidestep that problem by adopting Android app support. 

There are two issues with supporting Android apps, though. For one, Microsoft would basically have to admit that Universal Windows Platform apps are dead. Developers simply won’t have any reason to work with UWP anymore. The other issue is that Microsoft would have to convince Android developers to port content to Centaurus. It wouldn’t be nearly as much work as building an app from scratch, but it would still take some effort. The apps would need to be freed of Google dependencies and probably uploaded to a new store for easy access on the Centaurus.

The Microsoft Courier concept from 2009.

It’s hard not to compare this upcoming device with the long lost Microsoft Courier, a dual-screen tablet that only existed in a riveting concept video from 2009. It had a “journal-like” interface with unique multitasking features that made use of the “spine” in the middle of the two screens. Microsoft eventually confirmed the Courier existed in an early phase of development, but it ended the project before it could get very far. Now, Centaurus could fulfill the promise of that leaked video from a decade ago. 

IHS Markit cites supply chain data suggesting Centaurus could launch in the first half of 2020, possibly even the first quarter.

The Better Way To Browse The Web 25 Jun 2019, 3:27 pm

Over the weekend I read an article with a good premise that was just totally wrong about the conclusion, even though it was about a Mac application I know and love and use.

Use Pocket? If you read something online, Pocket is a wonderful way to ensure that whatever you capture online can be read on any device wherever you are and at any time. Pocket is free so what’s not to like?

Browse vs. Capture

Hayden Nanders, writing in Nylon, lamented the passing of Google Reader a few years ago because that’s the application he used to read everything online. Google killed Reader but Hayden could not find peace in any of the alternatives (some of which are better than the original; more on that in a moment).

Reader had a good run but Pocket is not a good replacement bit is a good add-on. Here’s why.

Pocket, previously known as Read It Later, is an application and service for managing a reading list of articles from the Internet… The application allows the user to save an article or web page to remote servers for later reading. The article is then sent to the user’s Pocket list (synced to all of their devices) for offline reading. Pocket removes clutter from articles and allows the user to adjust text settings for easier reading.

That description explains why Pocket is popular and why I use Pocket, too. What pocket does not do is what Google Reader did and what many other RSS news readers do better– find articles worthy of reading.

Here’s an example.

On iPhone and iPad I use Apple’s own News app and Flipboard app because both aggregate news articles from many sources, and while I can influence those sources I cannot easily control them. In iOS the Share button allows me to save an article in News or Flipboard (or websites and other applications) into Pocket. Good, right? And it couldn’t be much easier. Tap the Share button, select Pocket, and it gets saved into Pocket, then synchronized to Pocket on other devices.

What’s missing is the ability to grab news from sources that I want to gather articles. That’s where an RSS news reader comes in and why it can be as valuable, more valuable, and yet integrate with Pocket. What I use to aggregate my specific sources of information online is News Explorer; available on Mac, iPhone, iPad, Watch, and Apple TV.

Look familiar?

News Explorer for Mac

Unlike Pocket, which only captures news articles from sources you’re already reading, News Explorer allows you to capture and create those sources. Nearly every website these days has an RSS subscription feed which News Explorer uses to download to your Mac (or, iPhone, iPad, Apple TV) to review at your leisure. How it works is drop dead simple.

Go to a website you like and use News Explorer to grab the RSS URL. From then on News Explorer downloads recent articles; headlines and summary. That efficiency means you can browse through hundreds of articles in minutes, from dozens of websites that you choose. They can be categorized and organized to your liking, too.

Cool, right? Check this:

News Explorer

News Explorer gives you the same Sharing options in macOS and iOS. Find an article you want to save to read later, click the Share button, select how to save it– Pocket shows up if you have Pocket on your Mac or iPhone or iPad– and the article is saved and available to be read later. News Explorer also has options to save to Safari’s Reading List, Instapaper, and other options.

You can also use News Explorer to sync your RSS subscription list between devices. Pocket is great. Instapaper is great. Even Reading List in Safari is great. But all require you to find the articles you want to save for later and nothing does that better than an RSS news reader, of which News Explorer is tops on my list.

How to Fix iPad Stuck on Apple Logo Screen 25 Jun 2019, 3:26 pm

Rarely, an iPad may get stuck on an Apple logo screen when the device is booting or restarting. Getting stuck on the Apple logo usually happens during a failed software update, whether it was interrupted or incomplete, but it can sometimes happen during restores and during other operations as well.

If an iPad, iPad Pro, iPad Air, or iPad mini is stuck on an Apple logo screen, you can use the tips below to troubleshoot the problem and resolve the issue.

How to Fix an iPad, iPad Pro, iPad Air, iPad Mini Stuck on Apple Logo

This guide will aim to review troubleshooting solutions to resolve an iPad, iPad Pro, iPad Air, or iPad mini that is stuck on a black Apple logo screen. Follow in the order presented, and be sure to use the advice specific to the iPad model, as the troubleshooting steps differ between iPad with Face ID and iPad with Home buttons.

0: Wait! Does the Apple logo screen on iPad have a progress bar?

If the Apple logo screen has a progress bar underneath the Apple logo, then that likely means the device is installing a system software update, or is being restored. In that situation, you will not want to interrupt the system software update process.

If you see the Apple logo screen on an iPad and it has a progress bar underneath the Apple logo, let it sit for a while with the device plugged into a power source.

iPad with Apple Logo screen and progress bar

If a software update is being applied, the iPad will complete the installation and restart itself normally when it has finished.

You may pick up an iPad and notice it’s on the Apple logo screen seemingly out of nowhere if you have automatic iOS / iPadOS software updates enabled on the iPad. Just let the update complete, do not interrupt it.

If the iPad remains unresponsive and stuck on the black Apple logo screen for an extended amount of time, say after an hour or so, it may be stuck and need further troubleshooting. When the iPad is truly stuck on the Apple logo screen, use the troubleshooting tricks below to resolve the issue.

1: Force Restart the iPad

Sometimes simply forcibly restarting the iPad will resolve being stuck on an Apple logo screen. Forcibly rebooting an iPad varies on the iPad model and the iPad model year, use the instructions below depending on the specific iPad, iPad Air, iPad mini, or iPad Pro.

Force Restart iPad Pro 11″ and iPad Pro 12.9″ (2018 and newer)

You can force restart iPad Pro with Face ID (2018 and newer) including the iPad Pro 11″ and iPad Pro 12.9″ models, with the following instructions:

  • Press and release Volume Up, press and release Volume Down, press and hold Power button until the iPad Pro restarts

Force Restart iPad, iPad Air, iPad mini, and older iPad Pro

You can force restart an iPad with a clickable Home button, including iPad, iPad Air, iPad mini, and older iPad Pro models, with the following instructions:

  • Hold the HOME button and POWER button concurrently until the device screen turns off to black and back on to an Apple logo screen appears

Occasionally, force rebooting works and the iPad returns to the lock screen or home screen as usual. If not, carry on for more troubleshooting.

2: Update iPad with Recovery Mode (or Restore)

The next troubleshooting trick is to update the iPad using Recovery Mode. Using Recovery Mode requires the use of a computer (Mac or Windows PC) with a modern version of iTunes, and you will need a USB cable to connect the iPad to the computer. Much like force rebooting, entering Recovery Mode varies per iPad model.

Update iPad Pro with Face ID via Recovery Mode

If the iPad has Face ID and no Home button, you can enter Recovery Mode on iPad Pro (2018 and newer) with the following instructions:

  • Open iTunes on the computer (or Finder if Mac is running Catalina)
  • Press and hold the Power button and Volume Up button until the “Slide to Power Off” screen appears, then drag that slider to turn OFF the iPad Pro
  • Next, hold down the POWER button and connect the iPad Pro to a computer with a USB cable. Continue holding the POWER button until iPad is in Recovery Mode
  • Choose “Update” when the alert message appears on screen

Updating the iPad in Recovery Mode may take a while so be patient and let 20 minutes or so pass. If this is successful, the iPad Pro will update the system software and then reboot itself eventually back and work as normal.

If this fails, you will need to repeat the steps above, but at step 4 choose to “Restore” the iPad instead of ‘update’ (Important note: by restoring the iPad it will reset it as new and erase all data on the iPad, however if you have a backup you can restore from that backup when complete).

Update any iPad with Home button via Recovery Mode

If the iPad has a Home button, you can enter Recovery Mode on iPad, iPad Air, iPad mini, and older iPad Pro with the following instructions:

  • Open iTunes on the computer (or Finder if Mac is running Catalina)
  • Press and hold the Power button until the “Slide to Power Off” screen appears, then slide to turn OFF the iPad
  • Hold down the HOME button while connecting the iPad to a computer using a USB cable
  • Continue holding the HOME button until the iPad is in Recovery Mode and detected by the computer
  • Choose “Update” when the alert message appears on screen

Updating the iPad can take a while, give it at least 20 minutes to see if this works. If updating is successful, the iPad will reboot and become usable as usual.

If this fails, you will need to repeat the steps above, but at step 5 choose to “Restore” the iPad rather than update. (Important note: restoring the iPad will erase all data on the iPad and set it up as new, however if you have a backup you can restore from that backup during the setup after restore).

3: Erase & Restore iPad with DFU Mode

If the above Recovery Mode methods fail to resolve the issue, you can try to use DFU mode to restore the iPad or iPad Pro instead. DFU mode is a lower restore method that may work when Recovery Mode fails. Using DFU mode will erase the iPad completely, meaning all data on the iPad will be lost. If you have a backup of the iPad, you can restore the iPad backup to the iPad when DFU restore has finished.

Restoring iPad, iPad Air, iPad mini, older iPad Pro with DFU Mode

You can enter DFU mode on any iPad with a Home button with these instructions:

  • Connect iPad to a computer (Mac or PC) and launch iTunes (or Finder if Mac is running Catalina)
  • Hold down the POWER button and the HOME button at the same time, and continue holding both of those buttons for 10 seconds
  • After 10 seconds, release the POWER Button but continue to hold the HOME button for another 5 seconds
  • Choose to Restore the iPad with iTunes, this will erase all data on iPad and set it up as new

Restoring iPad Pro (2018 and newer) with DFU Mode

Entering DFU mode on iPad Pro with Face ID (2018 and newer) is achieved through the following steps:

    • Connect iPad Pro to a computer and launch iTunes (or Finder if Mac is running Catalina)
    • Press and release Volume UP, then press and release Volume DOWN, then press and hold the POWER button for 10 seconds
    • While still holding the Power button, also press and hold Volume DOWN button for another 5 seconds
    • Release the Power button but continue to hold Volume DOWN for another 10 seconds
    • When you see an alert on the computer that a device has been detected in recovery mode, choose to Restore to erase the iPad and set it up as new

When the iPad Pro has successfully restored you can either set it up as new or then restore it from an available backup during the setup.

Fortunately getting stuck on a black Apple logo screen is a pretty rare occurrence for iPad, and while the same thing can happen on an iPhone it’s also not particularly common to run into with that device either. Usually the troubleshooting steps outlined above will resolve the issue. Let us know in the comments below what worked to resolve your problem.

Tried all of the above and still stuck on an Apple logo screen? Something else may be going on, so the next best option is to contact official Apple Support or an Apple Authorized Repair Center for further assistance in repairing the iPad, iPad Air, iPad mini, or iPad Pro.

An important part of being a good beta tester is filing bug reports, so be sure to use the Feedback Assistant application to report every bug you encounter. The Feedback Assistant app sends filed reports directly to Apple.

Feedback in iOS

You can even use Feedback Assistant to request feature changes or report other issues.

Your feedback could help to patch bugs, or even help mold features in iOS 13!

Updating Future iOS 13 Public Beta Builds

Future updates to the iOS 13 public beta will arrive through the Settings app Software Update section as usual.

iOS settings icon

For example, when iOS 13 public beta 2, 3, or 4 is out, you’ll find them available in the Software Update area of Settings app.

Don’t forget to regularly update the public beta system software, as each new beta build will resolve bugs and issues found in prior beta builds.

How do I revert from iOS 13 beta back to iOS 12?

If you discover that iOS 13 public beta is not suitable for your usage or purposes, you can downgrade from iOS 13 beta and revert back to iOS 12 stable build assuming you made a backup in iTunes (or Mac with Catalina) earlier as described. If you did not make a backup, then you would either have to erase the device to restore to iOS 12, or simply stay on the iOS 13 public beta and continue to update as new versions are released periodically by Apple.

Apple has said that the final version of iOS 13 will be released in the fall of 2019, alongside iPadOS 13 and MacOS Catalina 10.15.

Hands On With DJI’s New RoboMaster S1 Battling Robot 25 Jun 2019, 3:25 pm

If you have a teenage family member or friend, you may be familiar with FIRST Robotics, but maybe not with DJI’s RoboMaster competition: Imagine FIRST times 10. RoboMaster pits teams of University students against each other, each fielding six custom robots designed and built according to certain specs and rules. DJI’s S1 is a simplified, scaled-down, version of one of the “standard” robots that you might see in RoboMaster.

Unboxing a DJI RoboMaster S1

The S1 comes in a few dozen pieces, with a graphical set of instructions for assembly. I’d place the difficulty as being a little harder than putting a LEGO robot together, and less stressful than assembling an Ikea desk. Once you have the S1 built and its battery charged (also the optional Gamepad if you’re using one), the next step is to install the app and log in to a DJI account. It seems a bit excessive to have to create or log in to an account just to play with a toy robot, but if you’re ever going to want to participate in a multi-player scenario it makes some sense. Weirdly, the mobile version of the app asks for permission to make and manage phone calls. Fortunately saying no doesn’t seem to hurt anything.

Here are the components for building a RoboMaster S1

Here are the components for building a RoboMaster S1.

Connecting the S1SEEAMAZON_ET_135 See Amazon ET commerce over Wi-Fi to your router uses a clever but sort-of-annoying approach of having you tell the app your SSID and password to generate a QR code you scan with the S1’s camera. It’s not a big deal to do once, but it appears to have to be repeated any time you want to connect the S1 to a different device. That makes it painful to (for example) use a PC for programming and a phone in the Gamepad for battle. You can also use WiFi direct or a USB cable to connect to the S1, so I suspect a good solution might be to use a USB-C cable connected to a PC for programming and then Wi-Fi with a phone for operating the S1.

If you

If you’re organized and use a nice desk as your workbench, this is what assembling an S1 looks like.

You can drive the S1 right away from the app, using the touchscreen on a phone or tablet, or keyboard and mouse on a PC. The Windows version is in beta, which may explain why it didn’t work on my laptop. You can also load your phone into the (optional) Gamepad-style controller, and rely on the controller’s joystick for movement and command buttons for operations like firing. I’m not sure why there isn’t a second joystick on the Gamepad for turning, but instead, you need to use your phone’s touchscreen (or change the settings so that the S1 rotates to follow whatever you do with the Gamepad). The real fun comes in when you start to program the S1 — either using some of the provided pre-built code or by learning to program it on your own.

The Mecanum wheels are a favorite of robot competitors everywhere, as they allow full freedom of motion.The S1 can either fire infrared beams or gel capsules (similar to the ammunition used in the RoboMaster competition — just make sure and soak them for a few hours, per the incredibly-small-print instructions on the bottle). The capsules are non-toxic and disintegrate into dust that can be vacuumed up. An LED can provide visual feedback on where the S1’s gun is aimed, as long as your surroundings aren’t too bright, but primary manual targeting is with the FPV camera that showcases a gunsight in the middle.

Of course, you can also program the robot to aim and fire. Six targets on the sides, front, and rear of the bot respond to infrared or physical impacts. The targets aren’t very large, so close range shooting is helpful. There is a 1080p FPV camera aligned with the gun, that you can livestream in the app. FPV mode helps you target, of course, but also limits your ability to see anywhere except where the gun is pointed.

For safety, by default, the S1 won’t let you fire beads when your barrel is raised more than 10 degrees above level, so its effective range is limited to a few meters. However, if you turn the safety off and raise the barrel, the gun does an impressive job of hitting targets as far as 15 yards away, as you can see from the below video. Of course, DJI encourages you to wear safety glasses and not aim at any people or animals! That said, even at 3 feet the capsules weren’t able to punch through the paper air gun targets I used to test it (but they could clearly cause damage to an eye, for example).

Programming the S1 in Scratch or Python

Scratch is a graphical, block-based, programming environment created by MIT Media Lab as an educational tool. It is similar to LEGO’s EV3 programming system but more extensive. For those who are already comfortable with programming, Python is provided as an alternative, and you can always see the Python code generated by a Scratch program in case you want to migrate.

If what you’re hoping to do is program a battle robot, then the provided set of blocks for Scratch is extensive and well thought out. You can start at the lowest level, directly programming the gimbal, the gun, and how the S1 responds to hits on its armor. Or you can mix and match some of the existing modules and build on them. At the most sophisticated level, there are subroutines for tracking a person, and for line following.

The programming module has a basic debugging interface, where you can run the program while looking at what the robot is seeing. Once you have a program working, you can run it manually, as a custom skill when doing Battle, or set it load when you put the robot in Autonomous mode. DJI promises a library of programming videos, but so far it looks like there is part of one is available. It covers interacting with the robots PIDs (Proportional-Integral-Derivative Controllers), but seems to skip the portion where actually programming the PIDs is explained).

Speaking of PIDs, by allowing direct control of them, the S1 programming environment provides some differentiation from many less-expensive alternatives. For those who are used to simple “tell the robot where you want it to aim” programming, under the surface, there is almost certainly an algorithm that relies on a feedback loop with a PID to actually turn to the target expeditiously while minimizing overshoot. With the S1 you can tweak the algorithms that drive the PID for yourself, to hopefully create a better targeting system than your competition.

A Little About the RoboMaster Competition

RoboMaster’s big event is head-to-head between two teams of college students. Until recently they were almost all from China, but in 2018 there were teams from a number of countries, including the USA and Japan. The bots weigh up to 80 pounds and are all custom built by the team. The compete on a complicated battlescape, with the drivers facing away from the action, and relying on a mini-map to see where all the other bots are on the field. Almost all of the action revolves around shooting. Bots load up with ammunition from supply depots and go to work. Each team can field a Hero robot, a Sentry robot, and some Infantry robots, and potentially even a drone. Teams get points for both inflicting and avoiding damage, with the higher-scoring at the end of the timed match winning.

Most coverage of RoboMaster is in Chinese, but if you’re curious about the inspiration for the S1, here is coverage of the first day of the 2018 competition.

Not the Best Robot for Other Applications

If you don’t want to fight, the S1 may not be the best robot for you. While the S1 has plenty of interesting AI-powered features and a solid programming environment, DJI’s choice of hardware is definitely battle-focused. For example, there are hit detectors on every side of the robot, but no Ultrasonic distance sensors that would be very helpful for autonomous navigation or SLAM applications. Similarly, you’re paying for a sophisticated gimballed gun that could be omitted or replaced by more cameras or other sensors for other applications. Or you could buy a Jetson Nano and build yourself a JetBot, for example. Speaking of which I now have a review JetBot in house, so we’ll be doing a hands-on article on it soon as well.

Great for Programming and Fighting

The S1 isn’t the best platform for hardware hacking. You can add on to it, but the basic robot only goes together one way. However, it has plenty of software flexibility, so if you want to get going with a battling robot without having to solder or source parts from all over, it’s a great option. Of course, you need $500 and some friends with a similar desire and budget to make the most of it. If you do want to have fun programming a battling robot and have the cash, the S1 is great.

How to override content type with Nginx web server 25 Jun 2019, 3:24 pm

I configured Nginx server. However, it is sending the wrong content type. I need to force Nginx to send specific “Content-Type: text/xml; charset=UTF-8“. How do I configure Nginx to override content type for given URL location?

Introduction – MIME is an acronym for Multipurpose Internet Mail Extensions (MIME). It is a standard that indicates the nature and format of a document, file, or assortment of bytes. All web browsers use the MIME type to determine how to process a URL. Hence, it is essential that Nginx send the correct MIME type in the response’s Content-Type header.

It is hard to keep the site running and producing new content when so many people block ads. Please consider donating money to the nixCraft via PayPal/Bitcoin, or become a supporter using Patreon.


How to see Content-Type header

Use the following curl command:
curl -I url
curl -I curl -I

Sample outputs:

HTTP/2 200 
date: Mon, 21 Jan 2019 12:07:22 GMT
content-type: image/gif
content-length: 377
cache-control: max-age=315360000

The content-type: image/gif indicates that image and subtype is gif image.

How to find out default mine types in Nginx

Look for config file named mime.types inside nginx config directory:
# find /etc/nginx -name mime.types
Use cat command or vi command to view mime.types file:
vi /etc/nginx/mime.types
View and force nginx to send specific Content-Type

Override content type with Nginx web server

Say when I request atom.xml file, there is
content-type: text/xml
And I want it to be correct one as follows:
Content-Type: content-type: text/html; charset=UTF-8
Again, I used curl command:
curl -I
How to override content type with Nginx on Linux
To fix this update your mime.types file:
# vi /etc/nginx/mime.types
And make sure following config exists:
application/atom+xml atom;
Save and close the file. Reload/restart the Nginx service. For example, GNU/Linux user can run:
# systemctl reload nginx

How to force Nginx to send specific Content-Type

Another option is to add the following directly to config file:

types {
    application/atom+xml    atom xml;

types {
application/atom+xml atom xml;

Nginx override content type for URL

It is also possible to override content type for given URL pattern. For example, I edited /etc/nginx/domains/ and added the following in server context:

    ### force utf-8 and content type, good bots for SEO ##
    location = /atom/atom.xml {
        ## override content-type ##
        types { } default_type "application/atom+xml; charset=utf-8";
        ## override header (more like send custom header using nginx) #
        add_header x-robots-tag "noindex, follow";

### force utf-8 and content type, good bots for SEO ##
location = /atom/atom.xml {
## override content-type ##
types { } default_type “application/atom+xml; charset=utf-8”; ## override header (more like send custom header using nginx) #
add_header x-robots-tag “noindex, follow”;

Save and close the file. Restart or reload nginx server:
# service nginx reload
Test it:
curl -I
nginx overwrite header and content-type

Ubuntu will support some 32-bit software confirms Canonical 25 Jun 2019, 3:15 pm

Ubuntu 32-bit

It seems that Canonical the development team responsible for the Linux Ubuntu operating system has backtracked a little on support for 32-bit software in future versions. Canonical has now announced to “change our plan and build selected 32-bit i386 packages.”

“Thanks to the huge amount of feedback this weekend from gamers, Ubuntu Studio, and the WINE community, we will change our plan and build selected 32-bit i386 packages for Ubuntu 19.10 and 20.04 LTS. We will put in place a community process to determine which 32-bit packages are needed to support legacy software, and can add to that list post-release if we miss something that is needed. Community discussions can sometimes take unexpected turns, and this is one of those.”

“We will also work with the WINE, Ubuntu Studio and gaming communities to use container technology to address the ultimate end of life of 32-bit libraries; it should stay possible to run old applications on newer versions of Ubuntu. Snaps and LXD enable us both to have complete 32-bit environments, and bundled libraries, to solve these issues in the long term.”

For the full statement on Ubuntu supporting 32-bit games and applications jump over to the official Ubuntu blog by following the link below.
