Decoliner: The $500,000 Double-Decker Motorhome | RIDICULOUS RIDES
A RENOWNED automotive artist has built a $500,000 motorhome that you can drive from the roof. Randy Grubb, from Oregon, is well-known for building beautiful and unique chrome vehicles. Some of his masterpieces include the Blastolene Indy Special, Jay Leno Tank Car, Decoson and the $500,000 motorhome – the Decoliner. Inspired by the 1980s sci-fi space traveller Flash Gordon, Randy spent over $100,000 in parts and 6,000 hours in manpower on the stylised mobile home. Using the chassis of a 1973 GMC motorhome which sports a front-wheel drive, it allows the frame of the Decoliner to be very low to the ground, around 14 inches. This means that Randy had enough space to stack the vehicle as a double decker and for an additional driving position on the roof low enough to fit under most bridges and overpasses. Randy and his wife drove the Decoliner all over America, putting over 15,000 miles on the camper without being stopped for the unusual driving position. Randy told Barcroft TV: “I always get asked ‘is that legal?’ Well, it’s not illegal.” Recently, Randy was invited to the Frankenmuth Auto-Fest in Michigan to show off the 26ft aluminium Decoliner. Joining Randy was the new owner of motorhome, Mike Jahns, who first saw the mobile home on TV and fell in love with the art-deco design of the vehicle. “It’s an amazing vehicle to be involved with because everybody smiles profusely at it, it just brings a lot of joy to people,” Mike said.

#! code: Drupal 9: Loading Configuration Entities Using Entity Query
Whilst working on a module I found that I needed to do something that was difficult to find information for. I think part of that is because the solution is simpler than I was thinking, but it did cause me to get lost in source code and internet issues for a while.
What I needed to do was to load in a list of configuration entities that matched certain parameters. The configuration entity I was dealing with was used to manipulate the output of a form, but only if certain conditions were met first. I thought that this information might be useful to others who are looking to load configuration entities.
In this article I will show how to search for configuration entities and how to load those entities once found. I’ll be using blocks for the examples here, but the same rules will apply to any configuration entities you want to load.
Loading The Entity Query Service
What we need to do first is get the entity query service. In case it wasn’t obvious (and it wasn’t to me) you can search for configuration entities in the same way as you would any other sort of entity. If you have used entity query to find users or pages of content then this is the same mechanism. There are, however, a couple of ways to go about doing this.
The first (and simplest) way of loading entity query is to just grab the object for the configuration entity we want to load.
$entityQuery = Drupal::entityQuery('block');
Whilst using this method does allow us to search for configuration entities, it doesn’t allow us to load those entities. To do that we need to use entity_type.manager service to find the storage for the configuration entity we want to load.
BIOS Memory Map for vmd(8) Rewrite in Progress
A rewritten version of vmd(8)‘s BIOS memory map handling could soon be appearing in -current.
In a recent post to tech@ and supplemented by an accompanying post to ports@ since the changes touch on SeaBIOS, Dave Voutila (dv@) describes the changes and the motiviation for changing them, ie
In short, this nukes some old hacks we've been carrying to communicate things like >4GB of memory to SeaBIOS via CMOS. It assumes vmd(8) properly builds and conveys a bios e820 memory map via the fw_cfg api.
Follow the links to the messages for the full story, test the patches if you feel up to it. While the ETA of the upcoming commit is not yet certain, expect to see this change go in soon.
Andy Wingo: we iterate so that you can recurse
Sometimes when you see an elegant algorithm, you think “looks great, I
just need it to also do X”. Perhaps you are able to build X directly
out of what the algorithm gives you; fantastic. Or, perhaps you can
alter the algorithm a bit, and it works just as well while also doing X.
Sometimes, though, you alter the algorithm and things go pear-shaped.
Tonight’s little note builds on yesterday’s semi-space collector
article
and discusses an worse alternative to the Cheney scanning algorithm.
To recall, we had this visit_field function that takes a edge in the
object graph, as the address of a field in memory containing a struct gc_obj*. If the edge points to an object that was already copied,
visit_field updates it to the forwarded address. Otherwise it copies the object,
thus computing the new address, and then updates the field.
struct gc_obj* copy(struct gc_heap *heap, struct gc_obj *obj) {
size_t size = heap_object_size(obj);
struct gc_obj *new_obj = (struct gc_obj*)heap->hp;
memcpy(new_obj, obj, size);
forward(obj, new_obj);
heap->hp += align_size(size);
return new_obj;
}
void visit_field(struct gc_obj **field, struct gc_heap *heap) {
struct gc_obj *from = *field;
struct gc_obj *to =
is_forwarded(from) ? forwarded(from) : copy(heap, from);
*field = to;
}
Although a newly copied object is in tospace, all of its fields
still point to fromspace. The Cheney scan algorithm later visits the
fields in the newly copied object with visit_field, which both
discovers new objects and updates the fields to point to tospace.
One disadvantage of this approach is that the order in which the objects
are copied is a bit random. Given a hierarchical memory system, it’s
better if objects that are accessed together in time are close together
in space. This is an impossible task without instrumenting the actual
data access in a program and then assuming future accesses will be like the
past. Instead, the generally-accepted solution is to ensure that
objects that are allocated close together in time be adjacent in
space. The bump-pointer allocator in a semi-space collector provides
this property, but the evacuation algorithm above does not: it would
need to preserve allocation order, but instead its order is driven by
graph connectivity.
I say that the copying algorithm above is random but really it favors a
breadth-first traversal; if you have a binary tree, first you will copy
the left and the right nodes of the root, then the left and right
children of the left, then the left and right children of the right,
then grandchildren, and so on. Maybe it would be better to keep parent
and child nodes together? After all they are probably allocated that
way.
So, what if we change the algorithm:
struct gc_obj* copy(struct gc_heap *heap, struct gc_obj *obj) {
size_t size = heap_object_size(obj);
struct gc_obj *new_obj = (struct gc_obj*)heap->hp;
memcpy(new_obj, obj, size);
forward(obj, new_obj);
heap->hp += align_size(size);
trace_heap_object(new_obj, heap, visit_field); // *
return new_obj;
}
void visit_field(struct gc_obj **field, struct gc_heap *heap) {
struct gc_obj *from = *field;
struct gc_obj *to =
is_forwarded(from) ? forwarded(from) : copy(heap, from);
*field = to;
}
Here we favor a depth-first traversal: we eagerly call
trace_heap_object within copy. No need for the Cheney scan
algorithm; tracing does it all.
void collect(struct gc_heap *heap) {
flip(heap);
uintptr_t scan = heap->hp;
trace_roots(heap, visit_field);
}
The thing is, this works! It might even have better performance for
some workloads, depending on access patterns. And yet, nobody does
this. Why?
Well, consider a linked list with a million nodes; you’ll end up with a
million recursive calls to copy, as visiting each link eagerly
traverses the next. While I am all about unbounded
recursion, an
infinitely extensible stack is something that a language runtime has to
provide to a user, and here we’re deep into
implementing-the-language-runtime territory. At some point a user’s
deep heap graph is going to cause a gnarly system failure via stack
overflow.
Ultimately stack space needed by a GC algorithm counts towards collector
memory overhead. In the case of a semi-space collector you already need
twice the amount memory as your live object graph, and if you recursed
instead of iterated this might balloon to 3x or more, depending on the
heap graph shape.
Hey that’s my note! All this has been context for some future article,
so this will be on the final exam. Until then!
The mass extinction of UNIX workstations
Back in the ’90s and very early 2000s, a whole market segment of computers existed that we don’t really talk about anymore today: the UNIX workstation. They were non-x86 machines running one of the many commercial UNIX variants, and were used for the very high end of computing. They were expensive, unique, different, and quite often incredibly overengineered. Countless companies made and sold these UNIX workstation. SGI was a big player in this market, with their fancy, colourful machines with MIPS processors running IRIX. There was also Sun Microsystems (and Oracle in the tail end), selling ever more powerful UltraSPARC workstations running Solaris. Industry legend DEC sold Alpha machines running Digital UNIX (later renamed to Tru64 UNIX when DEC was acquired by Compaq in 1998). IBM of course also sold UNIX workstations, powered by their PowerPC architecture and AIX operating system. As x86 became ever more powerful and versatile, and with the rise of Linux as a capable UNIX replacement and the adoption of the NT-based versions of Windows, the days of the UNIX workstations were numbered. A few years into the new millennium, virtually all traditional UNIX vendors had ended production of their workstations and in some cases even their associated architectures, with a lacklustre collective effort to move over to Intel’s Itanium – which didn’t exactly go anywhere and is now nothing more than a sour footnote in computing history. Approaching roughly 2010, all the UNIX workstations had disappeared. Development of MIPS, UltraSPARC (for workstations), Alpha, and others had all been wound down, and with a few exceptions, the various commercial UNIX variants started to languish in extended support purgatory, and by now, they’re all pretty much dead (save for Solaris). Users and industries moved on to x86 on the hardware side, and Linux, Windows, and in some cases, Mac OS X on the software side. I’ve always been fascinated by these UNIX workstations. They were this mysterious, unique computers running software that was entirely alien to me, and they were impossibly expensive. Over the years, I’ve owned exactly one of these machines – a Sun Ultra 5 running Solaris 9 – and I remember enjoying that little machine greatly. I was a student living in a tiny apartment with not much money to spare, but back in those days, you couldn’t load a single page on an online auction website without stumbling over piles of Ultra 5s and other UNIX workstations, so they were cheap and plentiful. Even as my financial situation improved and money wasn’t short anymore, my apartment was still far too small to buy even more computers, especially since UNIX workstations tended to be big and noisy. Fast forward to the 2020s, however, and everything’s changed. My house has plenty of space, and I even have my own dedicated office for work and computer nonsense, so I’ve got more than enough room to indulge and buy UNIX workstations. It was time to get back in the saddle. But soon I realised times had changed. Over the past few years, I have come to learn that If you want to get into buying, using, and learning from UNIX workstations today, you’ll run into various problems which can roughly be filed into three main categories: hardware availability, operating system availability, and third party software availability. I’ll walk through all three of these and give some examples that I’ve encountered, most of them based on the purchase of a UNIX workstation from a vendor I haven’t mentioned yet: Hewlett Packard. Hardware availability: a tulip for a house The first place most people would go to in order to buy a classic UNIX workstation is eBay. Everyone’s favourite auction site and online marketplace is filled with all kinds of UNIX workstations, from the ’80s all the way up to the final machines from the early 2000s. You’ll soon notice, however, that pricing seems to have gone absolutely – pardon my Gaelic – absolutely batshit insane. Are you interested in a Sun Ultra 45, from 2005, without any warranty and excluding shipping? That’ll be anywhere from €1500 to €2500. Or are you more into SGI, and looking to buy a a 175 Mhz Indigo 2 from the mid-’90s? Better pony up at least €1250. Something as underpowered as a Sun Ultra 10 from 1998 will run for anything between €700 and €1300. Getting something more powerful like an SGI Fuel? Forget about it. Going to refurbishers won’t help you much either. Just these past few days I was in contact with a refurbisher here in Sweden who is charging over €4000 for a Sun Ultra 45. For a US perspective, a refurbisher like UNIX HQ, for instance, has quite a decent selection of machines, but be ready to shell out $2000 for an IBM IntelliStation POWER 285 running AIX, $1300 for a Sun Blade 2500, or $2000-$2500 for an SGI Fuel, to list just a few. Of course, these prices are without shipping or possible customs fees. It will come as no surprise that shipping these machines is expensive. Shipping a UNIX workstation from the US – where supply is relatively ample – to Europe often costs more than the computer itself, easily doubling your total costs. On top of that, there’s the crapshoot lottery of customs fees, which, depending on the customs official’s mood, can really be just about anything. I honestly have no idea why pricing has skyrockted as much as it has. Machines like these were far, far cheaper only 5-10 years ago, but it seems something happened that pushed them up – quite a few of them are definitely not rare, so I doubt rarity is the cause. Demand can’t exactly be high either, so I doubt there’s so many people buying these that they’re forcing the price to go up. I do have a few theories, such as some machines being absolutely required in some specific niche somewhere and sellers just sitting on them until one breaks and must be replaced, whatever the cost,
