Microsoft vrea sa disponibilizeze 5000 angajati. Intre timp mai are o problema: i-a platit prea mult pe unii (eroare de sistem - cel mai probabil windows) si acum ar fi dorit banii inapoi de la acestia. Normal, banii au ramas la angajati. Acum ei sunt tinuti pentru a repara sistemul.

Nokia vrea sa reduca numarul angajatilor. Chiar ofera pachete avantajoase primilor 1000 de voluntari care vor sa paraseasca compania.

Si in Japonia sunt probleme. Deja se retrag de pe piata memoriilor si se reduce numarul companiilor de pe piata semiconductoarelor.

Se asteapta ca veniturile in industria semiconductoarelor vor scadea cu 24% in 2009. Se preconizeaza totusi si o crestere cu 7.5% in 2010. Desi in 2001, cand a avut loc o scadere record de 32%, a durat 4 ani pentru ca industria sa-si revina la incasarile din 2000.

Perioada de criza este una foarte buna pentru achizitionari. Asta si-a spus si Analog Devices care a achizitionat tehnologia pentru comunicatii PowerBUS RHINO impreuna cu toate patentele aferente. Analog Devices urmareste astfel adaugarea la portofoliul sau a produselor avansate de masurare a energiei.

Primul display touchscreen flexibil a fost prezentat de catre Arizona State University's Flexible Display Center. Acesta este rezultatul unui proiect dezvoltat in cooperare cu armata SUA, cea care va fi si prima care va folosi tehnologia. Dupa cum stim, armata este pionul principal in dezvoltarea tehnologica.

AMD va livra primele procesoare pe tehnologie de 32nm incepand din ultimul semestru 2010. Tot in urma Intel raman (ei incep productia in ultimul trimestru din acest an).

Lattice Semiconductor lanseaza primele sale FPGA-uri fabricate intr-un proces de 65nm. Tinta lor este segmentul mediu, segment in care concureaza cu Actel, Altera si Xilinx.

Incasarile la scara mondiala in industria circuitelor intgrate se estimeaza a scadea cu aproape 20% in 2009 pana la 199.2 miliarde$. Industria isi poate reveni la cifrele inregistrate in 2007 abia in 2012.

MOSAID Technologies, una din principalele companii detinatoare de licente pe piata semiconductoarelor si comunicatiilor, a anuntat ca a achizitionat un portofoliu de 300 de patente de la SercoNet Ltd. Acestea acopera in principal domeniul comunicatiilor.

Intel da in judecata Nvidia pentru a-i impiedica sa dezvolte chipset-uri pentru placile de baza care sa suporte noua clasa de procesoare Nehalem dezvoltata de Intel.

LG Electronics si Intel au anuntat ca vor colabora pentru a dezvolta dispozitive mobile pretabile la internet de mare viteza bazate pe noua generatie de platforme hardware furnizata de Intel

Cercetatorii de la Universitatea Rutgers au prezentat ceea ce pare a fi prima dioda reversibila compusa din materiale feroelectrice.

Producatorul de memorii Micron Technology Inc a anuntat ca va disponibiliza 2000 angajati pana la finele lunii august si va inchide productia de plachete de 200mm de la fab-ul din Boise, Idaho.

Tehnologie chinezeasca

Termenul de chinezarie este echivalent cu copie ieftina. Cu asta ne-am obisnuit din partea lor (a chinezilor). Se ia un produs occidental, se copiaza la diferenta milimetrica si se comercializeaza la kil. Exemple sunt multiple: telefoane cu cele mai neinchipuite functii, totul all-in-one, masini care seamana leit cu cele europene, jucarii, etc.

Chinezii sunt insa si foarte inovativi. Si descurcareti. In meseria mea ma tot mir cateodata cum de nu iese masuratoarea asa cum as vrea io. Tot o intorc, tot o sucesc si-o invartesc, da' nu iese. Zic ca oi fi gresit eu cu ceva setup-ul sau chiar design-ul produsului. Dar iata si o mostra de tehnologie de inalta clasa chinezeasca primita pe mail:

capacitor chinese style
Pai sa nu-ti dai palme peste cap? Te chinui ore-ntregi cu o masuratoare si descoperi o manarie de genul asteia. Deci asa se face capacitorul de 6800uF. Se incapsuleaza ala de 2200uF. Poate nu se prinde consumatorul. Doar-doar sa nu-i pice vreun circuit. E mare diferenta intre 2200uF si 6800uF. E ca si cand ai vrea sa scoti vreo 5V dintr-o baterie de 1.5V.

Una din marile mele enigme ramane: cum de merg circuitele cand stiu bine ce fel de erori apar in proiectare si testare?

Inginerii in actiune

Azi cica e una din cele mai deprimante zile din istorie. Deci nu din luna, nici macar din an. Din istorie. Asa au calculat oameniii de stiinta in lipsa de alta ocupatie (unii din ei cel putin). Sursele sunt multiple: criza mondiala, mijlocul lunii ianuarie ceea ce inseamna ca banii sunt pe duca, vremea rece si mai e destul pana la salariu si zi de luni.

Pentru a trec peste aceasta zi de maxima incrancenare m-am gandit sa ma mai destin putin si am cautat niste glume de domeniul meu. Asa ca iata niste bancuri cu ingineri (english version).

A group of Sales and Marketing experts were given the assignment of measuring the height of a flagpole. Wearing suits and ties, they marched out to the flagpole with their ladders and tape measures, falling all over themselves to get an accurate reading.

An Engineer comes along and sees what they're trying to do. He walks over, pulls the flagpole out of the ground, lays it flat on the ground, measures it from end to end, gives the measurement to one of the so-called experts, puts the pole back vertically into its slot in the ground and walks away.

After the Engineer has gone, the sales guy turns to a marketing guy and laughs. "Isn't that just like an Engineer?" he says. "We're looking for the height, and he gives us the length!

A priest, a doctor, and an engineer were waiting one morning for a particularly slow group of golfers.

Engineer: What's with these guys? We must have been waiting for 15 minutes!

Doctor: I don't know but I've never seen such ineptitude!

Priest: Hey, here comes the greenskeeper. Let's have a word with him.

Priest: Hi, George. Say, George, what's with that group ahead of us? They're rather slow aren't they?

George: Oh yes. That's a group of blind firefighters. They lost their sight while saving our club house last year. So we let them play here anytime free of charge!

(silence)

Priest: That's so sad. I think I will say a special prayer for them tonight.

Doctor: Good idea. And I'm going to contact my ophthalmologist buddy and see if there's anything he can do for them.

Engineer: Why can't these guys play at night?

A MBA and an Engineer go on a camping trip, set up their tent, and fall asleep. Some hours later, the Engineer wakes his MBA friend: "Look up at the sky and tell me what you see The MBA replies, "I see millions of stars."

The Engineer asks "What does that tell you?"

The MBA ponders for a minute: "Astronomically speaking, it tells me that there are millions of galaxies and potentially billions of planets. Astrologically, it tells me that Saturn is in Leo. Time wise, it appears to be approximately a quarter past three. Theologically, it's evident the Lord is all-powerful and we are small and insignificant. Meteorologically, it seems we will have a beautiful day tomorrow. What does it tell you?"

The Engineer friend is silent for a moment, and then speaks: "Practically...Someone has stolen our tent".

Three engineers and three accountants are traveling by train to a conference. At the station, the three accountants each buy a ticket and watch as the three engineers only buy one ticket.

"How are three people going to travel on only one ticket?" asks an accountant.

"Watch and you'll see," answered an engineer.

They all board the train. The accountants take their respective seats but all three engineers cram into a rest room and close the door behind them.

Shortly after the train has departed, the conductor comes around collecting tickets. He knocks on the restroom door and says, "Tickets, please!" The door opens just a crack and a single arm emerges with a ticket in hand. The conductor takes it and moves on.

The accountants see this and agree it is a clever idea. So after the conference, the accountants decide to copy the engineers on the return trip and save some money.

When they get to the station, they buy one ticket for the return trip. To their astonishment, the engineers don't buy a ticket at all.

"How are you going to travel without a ticket?" says one perplexed accountant.

"Watch and you'll see," answered an engineer.

When they board the train all three accountants cram into a restroom and the three engineers cram into another one nearby. The train departs.

Shortly afterward, one of the engineers leaves his restroom and walks over to the restroom where the accountants are hiding. He knocks on the door and says, "Tickets, please!"

Three engineers were in the bathroom standing at the urinals. The first engineer finished and walked over to the sink to wash his hands. He then proceeded to dry his hands very carefully. He used paper towel after paper towel and ensured that every single spot of water on his hands was dried. Turning to the other two engineers, he said, "At Dandish, we are trained to be extremely thorough."

The second engineer finished his task at the urinal and he proceeded to wash his hands. He used a single paper towel and made sure that he dried his hands using every available portion of the paper towel. He turned and said, "At McsWorld, not only are we trained to be extremely thorough, but we are also trained to be extremely efficient."

The third engineer finished and walked straight for the door, shouting over his shoulder, "At Infosys we don't pee on our hands."

Once upon a time there lived three men: a doctor, a chemist, and an engineer. For some reason all three offended the king and were sentenced to die on the same day.

The day of the execution arrived, and the doctor was led up to the guillotine. As he strapped the doctor to the guillotine, the executioner asked, 'Head up or head down?'. 'Head up,' said the doctor. 'Blindfold or no blindfold?' 'No blindfold.' So the executioner raised the axe, and z-z-z-z-ing! Down came the blade and stopped barely an inch above the doctor's neck.

Well, the law stated that if an execution didn't succeed the first time the prisoner had to be released, so the doctor was set free.

Then the chemist was led up to the guillotine. 'Head up or head down?' said the executioner. 'Head up.' 'Blindfold or no blindfold?' 'No blindfold.' So the executioner raised his axe, and z-z-z-z-ing! Down came the blade and stopped an inch above the chemist's neck.

Well, the law stated that if the execution didn't succeed the first time the prisoner had to be released, so the chemist was set free.

Finally the engineer was led up to the guillotine. 'Head up or head down?' 'Head up.' 'Blindfold or no blindfold?' 'No blindfold.' So the executioner raised his axe, but before he could cut the rope, the engineer yelled out: 'WAIT! I see what the problem is!'

Perspective bune pentru electronica in Romania

Se pare ca Romania va ajunge unul din cele mai mari centre de proiectare a circuitelor integrate din Europa. Asta conform unui studiu al analistului Harrish Natesan de la Frost & Sullivan.

"Romania devine unul din cele mai ieftine centre de proiectare din Europa avand in vedere ca cererea pentru locatii de acest gen e in crestere"

Motivele pentru care Romania este atat de favorizata le reprezinta localizarea geografica, politicile fiscale ale guvernului si costurile mici cu forta de munca (adica suntem ieftini la leafa, ne pot plati ca pe sclavi comparativ cu salariile din vest sau America).

Deci e de bine in domeniu. Se pare ca o sa am de munca din plin si in anii care vor veni p-aci pe plaiurile mioritice.

Viata sexuala a unui electron (EN)

Pentru binedispunere va propun un banc de electronisti. Daca este apreciat voi reveni cu mai mult umor electronist.

"One night when his charge was pretty high Micor Farad decided to get a cute little coil to help him discharge. He picked up Millie Amp and took her for a ride on his megacycle. They rode across Wheatstone Bridge, around by the sine wave, and stopped in a magnetic field by a flowing current.

Micor Farad, attracted by Millie Amp's characteristic curve, soon began to lower her resistance to minimum and his field was fully excited. He laid her on the ground potential, raised her frequency, lowered her capacitance, and plugged in his high voltage probe. He inserted it into her socket, connected them in parallel, and began to short circuit her shunt. Fully excited Millie cried "ohm, ohm, ohm".

With his tube operating at a maximum peak, and her coil vibrating from current flow, she soon reached her maximum peak. The excess current flow had gotten her hot and Micro Farad was rapidly discharging having drained off every electron.

They fluxed all night trying different connections and sockets until his bar magnet had lost all its field strength. Afterwords, Millie Amp tried self-induction and damaged her solenoid. With his battery fully discharged, Micro Farad was unable to excite her generator. So they ended up by reversing polarity and blowing each other's fuses"
