Why Redis Labs made a huge mistake when it changed its open source licensing strategy

No, Redis is not proprietary after Redis Labs introduced a tweak to its licensing strategy. Yes, some modules from Redis Labs will now be under a weird new license hack that says, in essence, Clouds, youre not allowed to make money from this code unless you pay us money. And yes, this hack was completely unnecessary in terms of open source evolution.

You see, we already have ways to accomplish this. Not everyone likes strategies like Open Core, but theyre well-established, well-understood, and could have saved Redis Labs some headaches.

SEE: Software licensing policy (Tech Pro Research)

Money for nothing

Lets be clear: Redis Labs desire is rational and common to open source vendors. While Redis Labs didnt touch the license for Redis Core (it remains under the highly permissive BSD), the company has slapped a Commons Clause onto otherwise open source software to make itnot open source. The rationale? Stop free riding, at least in part, as mentioned in the companys explanation:

[T]odays cloud providers have repeatedly violated this [open source contribution] ethos by taking advantage of successful open source projects and repackaging them into competitive, proprietary service offerings. Cloud providers contribute very little (if anything) to those open source projects. Instead, they use their monopolistic nature to derive hundreds of millions dollars in revenues from them.
Redis is an example of this paradigm. Today, most cloud providers offer Redis as a managed service over their infrastructure and enjoy huge income from software that was not developed by them. Redis permissive BSD open source license allows them to do so legally, but this must be changed. Redis Labs is leading and financing the development of open source Redis and deserves to enjoy the fruits of these efforts. Consequently, we decided to add Commons Clause to certain components of open source Redis. Cloud providers will no longer be able to use these components as part of their Redis-as-a-Service offerings, but all other users will be unaffected by this change.

This all makes sense. While people can disagree over whether free riding in open source is good or bad, Redis Labs policy change is a rational response to the stripmining that cloud providers do. We can argue over whether it will workI think the likelihood of an Amazon Web Services (AWS) or Microsoft Azure paying for the rights to build services based on these Common Cause/proprietary modules is less than zero, though arguably companies that might have preferred to buy those modules through a cloud will now be forced to buy them from Redis Labsbut what isnt really in doubt is that the approach is clumsy and unnecessary. (Not evil, as some seem to suggest.)

Established paths

You see, we already have well-established open source licensing strategies for inhibiting free-riding from the cloud vendors (or others). The most well-worn path is through the AGPL, sometimes referred to as the AWS GPL. The AGPL closes the GPLs famous network exception. Whereas its possible to run GPL code to provide a service over a network, the AGPL insists on code contributions back in this event.

Which, of course, is what Redis Labs is steering at with its Commons Clause, but in clunkier fashion.

Other companies like Cloudera, MongoDB, DataStax, and many others use an Open Core model, whereby they keep the core of their code open source but then license complementary modules or tooling under a proprietary license. Again, this is similar to what Redis Labs is doing, but rather than call an Open Core spade a spade, they do weird things like piggyback the Commons Clause on an otherwise BSD license, thereby making any software under this new licensenon-open source by definition.

SEE: How to become a developer: A cheat sheet (TechRepublic)

Why not just license these bits under an openly proprietary license? Why bother with the licensing gymnastics? If the company hopes to encourage contributions (Anyone can contribute to any of these projects (including those licensed with Commons Clause)), it wont work. Its very rare for developers to contribute to proprietary projects. It happens, but its the exception, not the rule.

Open source: Must-read coverage

This storm will pass, though my former MongoDB colleague Jared Rosoff is probably correct in suggesting on Twitter that: Even if the result of the change isnt controversial, its hard to trust a platform that can change on a whim.

Brian Leroux went further: They should be focusing on integration and multi-cloud. This wont solve anything other than alienating their base audience and top of funnel.

Redis Labs, in an attempt to buy itself some revenue, may have cost itself some credibility. Or not.

As unnecessarily complicated as Redis Labs approach was, its doubtful that it will seriously injure the companys prospects long-term. No, the real question is whether the company will benefit from the weird approach. In my experience, the answer is no, but maybe theyll break new ground.

Block Head Lab

Block head Lab or blockhead Labrador is a term used to describe English or show type Labs with broad, square heads and a distinctively chunky look. Well look at why this is significant to Labrador breeding, and how you can ensure your Lab has the block head look, if thats whats you want.

The blockhead Labrador Retriever is not without controversy, and well explain why people care so much. And well look at the risks of focussing too much on just one feature of a dogs appearance too.

What Is A Block Head Lab?

Its usually English Labradors that are referred to as block head Labs. In this context English Lab is a type of Labrador, not a description of where they come from! English Labs are also known as conformation Labs, show Labs, and bench Labs. They are bred to meet the physical ideal described in the Labrador breed standard. The best examples even compete in conformation competitions like the Westminster Dog Show or Crufts.

Blockhead Or Box Head Lab?

Both terms describe a distinctive physical feature of Labradors from English breeding lines. Anyone who knows their Labs will grasp your meaning from either. But, block head is the more commonly used term.

Types of Labrador: Which Labs Have Block Heads?

The Labrador breed is broadly divided into two different types. But several different names are used interchangeably to describe each type. Which can make matters confusing to the uninitiated. Heres how block head Labs fit in:

Labradors bred for their working ability and prowess in field and gundog trials are known as American, working, or field Labs. However, theyre not restricted to America they are popular all over the world. They tend to be slim and relatively lightly built. Their heads are also a relatively streamlined interpretation of the description given in the Labrador breed standard.

On the other hand, English Labradors are bred to match the physical description in the breed standard as closely as possible. This has resulted in several notable physical differences with the American variety, including broader heads.

So conformation-type English Labs have block heads, and working type American Labs usually do not. But it doesnt seem like head shape should be connected to working ability at all!

Types of Labrador Heads Recognizing A Block Head Lab

The Labrador Retriever breed standard says that Labs heads should be:

Clean-cut with broad back skull and moderate stop; powerful jaws; and kind friendly eyes, expressing character, intelligence and good temperament.

Its easy to see how words like broad and powerful have resulted in dogs with blockier heads winning more conformation show titles. Besides having broad skulls, they also tend to have slightly shorter muzzles than working dogs, and a more pronounced stop (the angle where the muzzle meets the forehead).

Other features of block head Labrador Retrievers

English Labs arent only recognizable by their heads though! Other signs that youre looking at an English Lab are:

They tend to be shorter and stockier than their American counterparts.
Their coat is often a little longer and thicker.
They are more likely to still have an otter tail, which starts off thick at the root and tapers towards the tip. The otter tail is though to act as a rudder and help them swim, but its increasingly missing from American Labs.

Blockhead Labrador Retriever Colors

Labradors of all types are accepted by the AKC in three standard colors:

Black Labs are the color most closely associated with the working gundog tradition, and thats true of the blockhead black Lab too. But besides a blockhead English black Lab you can also get a blockhead chocolate Lab, and a blockhead yellow Lab.

How heavy can a blockhead lab be?

Its important to acknowledge that the American Kennel Club doesnt officially distinguish between the two types of Labrador. And they dont have different size ranges for English and American Labradors either.

A typical female Labrador weighs between 55 and 70lbs, whilst most male Labradors weigh between 65 and 80lbs. These ranges cover both types of Lab, but an English Labradors weight is more likely to be near the top end of either scale. English Labradors tend to be an inch or two shorter than American Labradors as well, so that the way they carry their weight makes them look more heavily built.

As in any population, some individuals may be natural outliers. Or in other words be heavier than 80lbs. Puppies from big parents are more likely to grow up to be big themselves.

Why Dont American Labs Have Block Heads?

The differences between the two types of Lab exist due to generations of breeders making breeding choices based on slightly different priorities. English Lab breeders look for sires and dams with perfect looks and conformation show titles to continue their breeding lines. American Lab breeders look for dogs with lots of field trial champions in their pedigree.

Because they prioritise working success over perfect resemblance to the breed standard, American Lab appearance has gradually diverged from English Lab appearance over time. One such change is a shift towards more slimline faces with longer, more slender muzzles and a less prominent brow. But both types are still instantly recognizable and equally acceptable as pedigree Labs!

English Blockhead Lab Temperament

Obviously there is more to a box head Labrador than just their head shape! English Labs are often said to be more calm and placid than American Labs. This is because they dont need the same degree of energy and stamina that working dogs need to fulfil their purpose. Successful show quality English Labs also need to be rather good at sitting around and waiting patiently for the next thing to happen. And they need to be unfazed by lights, noise, handling and large crowds of people and dogs.

However, the differences between English and American Labs are also, to an extent, just generalizations. Both types belong to the same active, energetic breed, and English Labs should still be capable, competent working dogs. So a blockhead Labrador Retriever can still be bouncy, high-spirited, tireless, and need several hours of exercise a day to wear out! Labradors of both types should be friendly, devoted, and people-focused.

Is An English Blockhead Lab Right For You?

Some people are drawn to a blockhead Lab vs regular (American) Lab because they think they are more impressive to look at. Whilst other people have heard that an English blockhead chocolate Lab will be calmer and more chilled out than a chocolate Lab from working lines, and like the idea of the dog who requires less effort to look after.

English Labradors still need at least two hours of exercise a day, and lots of interaction and mental stimulation. They are best suited to households which have plenty of time for walking, training, and playing games. Adult blockhead Labs are usually described as being patient and affectionate with children, but they can be boisterous and bitey as puppies. All types of Labrador are playful, especially as puppies, so if you have enthusiastic teenagers it can really help with sharing the task of occupying them.

Finding Block Head Labs For Sale

To find big head Labrador dogs for sale, look for breeders who advertise English Labrador or conformation Labrador puppies for sale. The pedigree for each parent may also show several conformation champions. Show champions are identified by the prefix CH before their registered name. The prefix GCH means grand champion!

Beware of breeders who specifically advertise block head Labs for sale rather than English or conformation Labs. This reveals a lack of understanding and knowledge about the breed. It also suggests a preoccupation with breeding exaggerated big head Labrador dogs. In fact, the Labrador breed standard specifically penalizes dogs with overly large heads. It says:

(paid link)

The skull should be well developed but without exaggeration. A wedge-shape head is incorrect, as are massive, cheeky heads.

The risks of breeding for a single feature

Placing too much emphasis on achieving a block head can also have dangerous repercussions for a dogs overall health. For example, a naive or unscrupulous breeder who wants to produce puppies with very boxy heads may choose sires and dams based purely on the shape of their head. They might even forego health testing, or ignore poor health test results. They might also choose dogs with poor temperaments. Their puppies might end up looking the way they want, but they could end up with heart breaking or expensive health problems. Or behavioral problems which are difficult to overcome.

Block Head Lab

Block head Lab is a description applied to Labradors from conformation or show type breeding lines. They are also known as English Labs, although they dont have to come from England. Block head Labs have broader heads than dogs from working lines, with a shorter muzzle and more pronounced brow bone. Overall, their entire body is broader and stockier too. Block head Labs may be more laid back than working Labs with more streamlined faces, but this is a generalisation which doesnt always hold true. If youre looking for a Labrador puppy at the moment, look for breeders who make the health and temperament of the puppies top priority. Walk away from breeders who compromise these things to achieve a particular look instead.
