Printer issue - WSD port

At some point in life in the past several weeks something happened to my printer and it started having issues printing. The printer is an HP Deskjet 2600 series. The issue was print jobs would get jammed in the queue and I was unable to delete them. The process was:

ZombieLoad - A new but not so new threat

The latest threat to computers is the Zombieload vulnerability.

So many of the known threats to computer devices are because of how the software or hardware was created. The exploits and vulnerabilities we discover are flaws in how the system or code was constructed. Is it possible that we just didn’t have the tools we needed to test for security flaws?

Karen Carrier, one of Memphis' most prolific restaurateurs, considers Jamaica something of a second home. She said she's been traveling there for about 17 years, and it serves as an inspiration of her latest ventures Back Dō/Mi Yard, which opens this week.

The Watchmen TV series has finally landed on our screens – the first episode of it, at least. And if you’ve skimmed through our Watchmen beginner’s guide, you’ll have a decent understanding of how the original Watchmen comics have cast a shadow over the action.

But the best TV shows are never easy, and you might be wondering what to make of Watchmen episode one – or if there’s something you missed while texting, blinking, or chatting about the show in your living room.

This page will guide you through the key questions you may have about Watchmen episode one – obviously with some spoilers - or discover how to catch up with our guide on how to watch Watchmen online

1. What's all this about the Seventh Cavalry?

The story kicks off 30 years after the events of the graphic novel, which is taken as canon for the events happening onscreen. In an alternate timeline to our own, masked vigilantes not only exist, but are treated as outlaws. At the same time, state police officers resort to donning masks themselves to protect their own identities in the fight against a band of white supremacists, the Seventh Cavalry – who, much like show creator Damon Lindelof, have riffed on their source material, taking the writings of the deceased character Rorscach as gospel for their racist ideology.

We’ve seen at least one police officer killed by the group, and the police force has been granted access to more firepower to meet this threat. 

2. What were the Tulsa race riots?

The historical flashback that the show opened with was the Tulsa race riots of 1921, a real-life event where swarms of white American citizens descended on the population of Tulsa, Oklahoma – trashing businesses and killing hundreds of black residents. It has been called “the single worst incident of racial violence in American history.”

A young boy caught up in the violence is shown wandering away from the wreckage of a carriage shot from behind – and seems to be the same person found with the body of police chief Judd Crawford (more on that later).

The brief mention of “Redfordations” in the classroom appears to be a system of reparations granted under Robert Redford’s presidency, allowing descendents of those affected by the riot some kind of financial support – and it’s clearly a sensitive subject within the TV show.

3. What is American Hero Story?

American Hero Story would be a somewhat clumsy name for a TV show, if it wasn’t such a clear play on words around the American Horror Story anthology series. You’ll catch sight of the title on various vehicles – and a blimp – in the first episode, with an audio announcement stating that “tomorrow night, the countdown ends. American Hero Story: The Minutemen.”

It seems that the history of the comics is being adapted for TV in HBO’s TV adaptation too – though how they’re represented, and how it matches up with reality, may well be explored in later episodes.


Regina King as Sister Knight.

4. What was White Night?

The chillingly named White Night sounds like a classic Christmas horror movie, and its use in Watchmen episode one isn’t far off. It marks the Christmas eve when members of the white supremacist group Seventh Cavalry attacked the homes and families of Tulsa’s police force, leaving many dead and others injured – and sparking the use of masks for police offers wishing to keep their identities safe.

5. Where is Nite Owl? Have we seen him yet?

While there’s no explicit mention of Nite Owl, the owl-themed vigilante from the Watchmen comics, there’s plenty to suggest his presence in the story. Regina King’s character is seen holding an owl-shaped mug in the police chief’s office, while Nite Owl’s flying contraption (“Archie”, as its known in the comics) is seen flying, diving, and crashing while under the command of the same police chief.

The Nite Owl persona was passed down to Daniel Dreiberg in the comics (as seen in the 2009 film), so it’s possible we’ll see a brand new character who’s taken on the mantle – or an old character returning to do so.

6. Did squid really rain from the sky?


It’s likely a reference to the giant squid that demolished Manhattan in the comics – which was the original endgame threat that brought humanity back from the brink of annihilation, though it’s unclear whether Adrian Veidt’s hoax was ever revealed as such to the American public. And if the original squid was a fake, we’re unsure where these squid rainstorms may have come from.

Literally squid on a windshield.

7. What's in the pod?

Tim Blake Nelson takes on a curious role as the police interrogator, though it’s not the vein you usually see in American crime dramas. Nelson’s character – Looking Glass – wears a reflective mask and asks a suspect leading questions in some kind of interrogation chamber filled with flashing images, seemingly to confuse or disorientate those brought in. While not a mind-reading superpower, it’s a good example of the enhanced, trained abilities of the heroes in Watchmen, as well as harking back to the psychological examinations Rorschach went through in the comics.

8. Who killed Judd Crawford?

Chief Judd Crawford is found hanged at the end of the episode, but the circumstances around it aren’t exactly clear. While the Seventh Cavalry seems the obvious choice, the mysterious wheelchair user seen earlier in the episode is the only one nearby, and seems to be the one who summoned Sister Knight to the spot. His prior lines also asked whether he “he could lift 200 pounds”, which could have been foreshadowing to him lifting the police chief’s body.

The blood-spattered badge has more than a passing resemblance to the smiley pin worn by The Comedian in the comics.

9. What is Jeremy Irons even doing?

Hard to answer this one. The Tony, Emmy, and Oscar-winning actor is clearly up to something as billionaire Adrian Veidt, though how his time spent in the countryside with a number of servants – with terrible table manners, apparently – is yet to be revealed. But the use of a horseshoe for a knife, and seemingly lacking mental faculties of Veidt's butlers, suggests something is amiss – and we wouldn't rule different dimensions out.

Jeremy Irons is chilling in the countryside, apparently.

10. When's the next episode out?

You can look forward to more confusion – maybe with some answers – next week at the same time. Head to our how to watch Watchmen online piece for more details.

With the launch of the Pixel 4 and Pixel 4 XL, fans were somewhat disappointed to hear they’d lose the long-standing offer of unlimited, free, original quality uploads to Google Photos – an offer that had been present across all three of the previous Pixel phone generations.

To add insult to injury, a Redditor (/u/stephenvsawyer) revealed that iPhone users do currently get unlimited Photos storage, but as Android Police discovered, this is about to change. 

Free ride

While it's free for Google Photos users to have as many 'high quality' images as they want, if you don't pay for a premium account, any image stored in 'original quality' counts towards the account's total maximum 15GB storage limit, which also includes other services such as Drive, Docs and more.

Since iOS 11, iPhones have been using the HEIC file format to take photos and store them locally on the device. One of the main benefits of such a format is that it compresses the image more than the JPEG format does and thus takes up less storage space.

Because the premium subscription for Google Photos measures its ‘original quality’ uploads by its file size, users uploading anything in the HEIC format would technically still fall under the limit (16MB), while also being able to store and retain the photo’s original resolution.

Bug fix?

Android Police reached out to Google about this quirk, and the software giant responded by stating that it was aware of the workaround and would be fixing the ‘bug’.

No details were revealed on how Google intended to ‘fix’ this issue, however. Some such possibilities include lowering the file size threshold for HEIC images to be considered ‘original quality, compressing them into even smaller HEIC files, or forcibly converting them to JPEG images once uploaded.

None of these options are overly ideal for the consumer, but Google will need to do something so as not to disadvantage its own customers while giving users of competing products a free ride. We’ll keep you updated on how Google decides to best resolve this issue.

With Nikon introducing a brand new APS-C (DX format) Z series camera into the mix, it begs the question: do you need to buy the more expensive full-frame Z6 mirrorless camera?

Both are designed to be great all-rounders, but that extra real estate for the Z6 image sensor sees an asking price of more than double that of the Z50’s. If you’re a travel photographer, there’s also the fact that the Z6 is bigger, heavier and bulkier too. 

In this comparison we’ll discover the key differences between the two cameras to help you decide whether you should splash the cash or save the pennies. 

Nikon Z50 vs Nikon Z6: Sensor and resolution 

Of course, the biggest difference between these two cameras is the sensor size. The Z6 totes a 24.5 megapixel full-frame (what Nikon calls FX format), while the Z50 has a smaller APS-C (DX format) 20.9 megapixel sensor. Despite it being the same resolution as the Nikon D500 sensor, Nikon claims the Z50 is not the mirrorless equivalent of the DSLR. 

A full-frame sensor is generally better in low light, while the higher resolution should mean it’s also better suited to capturing fine details as well. Whether you need the larger sensor very much depends on what you like to shoot. If you’re consistently shooting in gloomy conditions, the Z6 will undoubtedly perform better but if, on the whole, you’re shooting in favorable conditions (such as while traveling), then the Z50 should be more than adequate.

The Z50 has a smaller sensor than the Z6

Nikon Z50 vs Nikon Z6: Lenses

Both the Nikon Z50 and the Z6 use the same Z lens mount. That means that all of the existing Z mount lenses available for the Z6 and the Z7 can be used with the Z50. As the sensor is smaller, you’ll need to take into account the crop factor – so the 35mm f/1.8 S series lens would offer an equivalent focal length of around 52mm. 

Additionally, two new Z mount lenses have been announced for pairing with the Z50, specifically designed for use with the smaller sensor. These are a 16-50mm f/3.5-6.3 kit lens, and a 50-250mm f/4.5-6.3 telephoto zoom. The former is designed to keep the overall system as compact as possible and, again, is great for those looking for a travel-friendly snapper.

Nikon published a lens road map recently which showed that there will be more lenses announced throughout 2020 and 2021 designed for both its mirrorless systems.

Nikon Z50 vs Nikon Z6: LCD screen

Here’s a good example of another reasonably big difference between the two models. 

While both have a 3.2-inch LCD screen, the Z6 has a higher, 2100K-dot resolution display as compared to the 1040K-dot resolution on the Z50. Used in isolation you may not realize what you’re missing out on, though. 

The Z50 also has an extra trick up its sleeve – it can tilt to face all the way forwards, which is great for selfies and for recording vlogs to camera. The Z6’s screen can tilt, but only downwards and slightly upwards. 

Nikon Z50 vs Nikon Z6: EVF

Both cameras have electronic viewfinders, but the EVF on the Z6 – which is the more expensive of the two shooters – is both higher in resolution and size. 

The Z50’s EVF is a 2360k-dot, 0.39-inch device, compared to the Z6’s 3690k-dot 0.5-inch option. Again, it’s likely that if you only ever use the smaller, lower resolution EVF of the Z50 you won’t know what you’re missing out on. 

Nikon Z50 vs Nikon Z6: Burst shooting

Here’s another point where the Z6 and Z50 are reasonably similar: the Z6 offers 12fps shooting, while the Z50 sits only slightly behind at 11fps, with both speeds sufficient for shooting sports and action. In fact, you might argue that with the crop sensor, and the longer lens available for it (for now), the Z50 is the best option out of the two. 

Nikon Z50 vs Nikon Z6: Memory card 

The Z6 uses a single XQD card, while the Z50 has a single SD card slot. Although XQD cards are faster and more robust, they’re also significantly more expensive and less easy to find than SD cards. 

If you’re already shooting with another camera, you might already have an existing supply of SD cards available to shoot with. As the physical size of an SD card is also smaller, it helps to keep the overall size of the Z50 to a minimum. 

Nikon Z50 vs Nikon Z6: Battery life 

Another specification which helps to save space – the Z50 uses a much smaller battery than the Z6. 

The official CIPA rating for the new EN-EL25 Z50 battery has yet to be announced, but it’s bound to be less than the Z6. That said, with a lower resolution sensor, plus a lower resolution screen and viewfinder, overall power consumption is likely to be lower.

As for the Z6, its EN-EL15b battery life is officially rated at a meager-sounding 310 shots – but in real-world usage you can usually get much more from it, typically lasting at least a whole day for the average user.

Nikon Z50 vs Nikon Z6: Dimensions and weight

Here’s where the Z50 has a trump card if your ultimate concern is portability. 

Weighing in at just 450g (including battery and memory card), it’s over 200g lighter than the 675g Z6. On top of that, the 24-70mm f/4 lens for the Z6 will add another 500g to your kit bag, while the 16-50mm f/3.5-6.3 kit lens for the Z50 is only 135g. 

As for dimensions, the Z50 is essentially a miniaturized Z6. It retains a deep grip and decent handling while only being 126.5 x 93.5 x 60mm, as compared to the Z6’s dimensions of 134 x 100.5 x 67.5mm. 

It could be that you prefer the beefier, bulkier Z6 in terms of handling, but it’s hard to deny the Z50’s appeal as a travel-friendly camera.

Nikon Z50 vs Nikon Z6: Price

So here’s the big one – price. Both are excellent cameras, but if you’re on a tight budget, the Z50 offers fantastic value for money. 

At the time of writing, it retails for around $856 / £849  body only (you'll only get the kit bundles in Australia), or $996 / £989 / AU$1,799 with the 16-50mm kit lens. You’ll need to double your investment if you’re keen on the Z6, which will set you back around $1,996 / £1,699 / AU$2,999 body only, or $2,596 / £2,249 / AU$3,999 with the 24-70mm f/4 lens.

Nikon Z50 vs Nikon Z6: Conclusion

There’s a lot to like about both the Z6 and the Z50. We’re yet to fully test the Z50, but our initial impressions are very good. By now, the Z6 is more of a known quantity, and we’ve been very pleased with how it performs. 

We’d happily recommend the Z6 as a travel-friendly camera – it is still small when compared to equivalent DSLRs. If you want the best image quality, then it makes more sense to go for the full-frame option and, of course, it’s cheaper than it’s higher resolution Z7 sibling. 

However, if your key desire is to have something small, lightweight and a fantastic all-rounder, the Z50 probably makes more sense, especially if you’ll mainly be shooting in good light.
