Ask Slashdot: What Are the Strangest Features of Various Programming Languages?

hedley OPS5 (728 comments)

A rule based language. 1000's of productions can be waiting to fire by querying a database (lhs waits, fires, triggers rhs updates). In my mind, its a bit like a seeing a VHDL language meet a database wrt the parallelism that comes out from it.

Programs written in it don't look at all like programs you normally would write in the life of a typical coder.

It's Time For the Descent Games Return

hedley Descent + SpaceOrb 360 (251 comments)

Sadly, the SpaceOrb never really caught on (too hard for many to use so I heard, or at the other end of the spectrum purists preferred mouse and kbd). I have about 4 of them, they are old school RS232 9600 baud, far behind the curve for plugging into the HID USB world we live in now.

Winklevoss twins.

I you believe their comments here, @120$ in the article, they feel it has 100x to go... that would be... $12000? Still a ways to go yet if their
prediction is right.

20-Somethings Think It's OK To Text and Answer Calls In Business Meetings

hedley Re:Wtf? (453 comments)

Take the call. The world revolves around *you*. A sense of entitlement surrounds *you*. Ideally the call should be in a disparate language to the general meeting group. Lets assume English for the meeting, then the call would be in Hebrew, French, Farsi, Cantonese etc (esp languages where speakers naturally raise their tone when in heated conversation). Don't forget to speak loudly and quickly!, cell phones have notorious connection issues, make sure the other party hears *you*!. You are *important* your ideas and thoughts have a lot of merit that need to be conveyed one-way over the handset, everyone in the room realizes that and will make allowance for *you* because of the stature you present.

Imagination Tech Announces MIPS-based 'Warrior P-Class' CPU Core

hedley Re:32 bit? (122 comments)

I think it stems from the initial directions each co took.

MIPS started from a 32bit Stanford grad project (MIPS-X) spun out to become the R2000 workstation class CPU. No hint of embedded arch at all at that time.
They steamed on finally hitting 64bit archs relatively quickly. Once they got to the R4K32 series and upon adding MIPS-16, they had a small footprint embedded soln but...

ARM started from basically a hobbyist computer, already with some small footprint pedigree built in. Very quickly Thumb was adopted, arch just as a translator initially but subsequently with on chip native decode. Now they have a 64bit arch, but because of their small footprint roots and aggressive licensing, they
really caught the lions share of sockets. They can now come to capture a 64bit space that was MIPS's to own years ago by osmosis of the socket market.

ARM had a first mover advantage in embedded and they executed well and did not allow competition to unseat them. It could have been different, they could have mucked up a design and lost share, but that did not happen.

Both companies have first rate tool chains also (that can be a deal killer). Thus its a wash for softies when HW pitches a design, if the license is favorable, and the die area+power draw meets managements expectations, then that vendor will get the nod for new IP. ARM has been fortunate in that there is also a bit of industry simpatico wrt ARM adoption... others are using it, so why not us?

Nest Protect: Trojan Horse For 'The Internet of Things'?

hedley The Internet of Disposable Things (177 comments)

1) When the CO sensor exceeds 5yrs. Replace: cost $129
2) CO sensor on the ceiling. Not where CO collects
3) For the A/C model, just 2 wires, not the red 9v interconnect protocol (Firex, Kidde). Thus all alarms (n * $129) need to be installed. This cannot coexist with a legacy detector system and provide the interconnected alarm.

Pretty enclosure though and the alerts are cool (verbal and web).

I just installed 7 A/C ionization alarms @9$ each. Good for 10years all interconnected.

Walking Distance from Wired: Kevin Kelly Surveys the Tech Scene

hedley slashdot via wired 13years ago... (27 comments)

The bubble has formed obviously. A new crop of 20 somethings are at the helm, the prior 20 somethings flushed so that the new ones can stake 'first mover advantage'. With a bubble cycle of 10+ years, its essential to keep employing 20 somethings or the employees will have actual memory or working in the bubble economy. (not to mention a) most likely single b) low wages). But... its not a Ponzi scheme right? (if we could just get some more eyeballs)...

Then I read the Grove in SF on Chestnut is folding under the crippling 20k/mo rent (50% rent increase). Somethings driving up prices... wonder what? ;)

Turning the Belkin WeMo Into a Deathtrap

hedley On a server with an HD? (146 comments)

There I was, deep in dreamland one night when, from my server room I heard a faint beeping noise at regular intervals... Groggy, I wake up, totter over to the 'server room' door (spare bedroom) and have a gander. In a groggy state it took me a moment in the dark to perceive what was going on, the APC UPS was power cycling the server and other ancillary items at a regular interval, turns out, when the battery goes south, the UPC just crowbars the AC and reboots (repeat...). Now, HD's were connected to the server and each one was cycling up for a few seconds, then spun down only momentarily etc. Terrible on spinning media. Luckily all was well in the end but its important to understand the failure modes on UPCs for your application esp if spinning media is connected.

50 Million Potentially Vulnerable To UPnP Flaws

hedley V1.0? (138 comments)

How many vendors are going to patch some obsolete hw to get the lib updated? I would be surprised if they can build images for some of those old products. That said, it seems a bit of an uphill crack, you have to know the target CPU, the lib version, and prepare a useful injection rather than just a denial of service. Still, it is interesting that people are still acting as documented on data coming over the wire, sprintfs into buffers with %s was an eye opener to me. These days for web stuff I use the c++ string class, fixed c buffers look weak to me with unvalidated socket input.

ClearDale Mental Health Facility 2033

hedley hedley writes  |  about 11 years ago

Doctor Erdans notes Jul 8th 2033

Patient Darl McBride is a 70 year old paranoid delusional disorder subject that we have been treating since his arrival at the facility.
He is beset by frequent rambling tirades. Most of these episodes are flashbacks to some period in his life where he felt he owned something or was entitled to something that was plainly not his. This behavior has persisted on throughout his life and even today we have had numerous incidents with him claiming ownership of items that are unquestionably not his. To wit, yesterday he removed the batteries from the TV remote in the recreation room and was seen jumping on the chairs with the batteries clenched in his fist as he wildly was yelling that the TV was his and that all the patients owed him money for each hour they were watching it. Nurse Williams assisted by Nurse Walters restrained him and placed him back in his room on an increased Thorazine drip.
He freqeuntly threatens other residents telling them that he is going to examine their things. Most of his tirades center on this theme that other residents have taken things from him and are hiding these items in their rooms.
He is abusive to staff who often try to compromise with him and go with him to see what things he has claimed are "stolen". He never agrees to this and instead just claims items he finds and begins a new tirade waving the newly grabbed item claiming it "matches" something of his.

Unusual behaviour and amusing for what it is to a point but I am concerned for the safety of the residents here. He is prone to these outbursts and I do believe he may become violent.

Recommendation is to maintain the increased Thorazine dose until I see some improvement in his overall comportment.


SCO ShakeDown

hedley hedley writes  |  more than 11 years ago

So what happens when the ShakeDown goes international? I.e. if they start sweeping the IP space for Linux TCP/IP fingerprints, whois'ing them and, if available, a contact, start emailing the contacts (or ISP's) indicating that a 'scofflaw' exists at that IP and a tithe is needed?

They really could get a fantastic revenue stream out of this. Would you pay a shakedown fee or represent yourself to maintain that your kernel was clean? Would you submit to a review of the code on your box at that IP addr? Do you have the time and funds to resist this discovery?

What a royal pain! I don't expect to have to pledge an oath of fealty in this day and age!



Cheap 64bit computing

hedley hedley writes  |  more than 11 years ago

Today it costs >100k$ for a large Sun machine with 64bit addressing and the ability to load 12Gb of physical ram. Next year, AMD and Intel will be introducing 64 bit server chips. The AMD offering (Sledgehammer, Opteron) will be the least pain in my opinion to get software going on it. Once that time comes, jobs that once used to be the domain of Sun/Solaris machines will become the work of cheaper farms of AMD/Intel based cpu's. The effect of this will be pronounced since companies that depend on simulations (IC companies for example) can afford to have more of what is usually a fairly tight resource. Sun will still enjoy it's large processor #, large memory capable machines but many tasks that once required that large iron will get migrated to these cheaper alternatives.


In the limit

hedley hedley writes  |  more than 11 years ago

As the telecom space continues to melt down and as the good engineers at these places go on the dole or find work in other non-telecom fields, who is going to make these switches hubs and routers when, in the limit, those legacy ports start going dark? Technology is momemtum based, left unattended, it will slip back into the primordial ooze and we will be reinventing the vacuum tube. Hmmm an edge router made from vacuum tubes...
