Let them cars share traffic information.

Introduction

Business to business (B2B) and Business to Customer (B2C) principles are well known. This article will investigate some aspects of a car-to-car network connecting wirelessly to enable car computer users to share timely traffic related information.

Background

The evolution of Global Positioning Systems (GPS) communities created repositories of tracks, routes and points of interest. These are mainly to date static in nature.

One such repository is of traffic cameras, others for business and resources like fuel stations and places to eat. Many a category exists.

Dynamic categories to date have not been deemed feasible due to the time dependence or duration of the event. Categories that are identified as dynamic may include the following:

• Vehicle accidents
• Mobile speed traps
• Broken traffic lights
• Traffic congestion
• Road blocks
• Fire
• Natural disasters

These categories are location dependant and therefore needs to have a GPS location associated with it.

Approach

Benefits of having real-time data during navigation allow the driver to evaluate alternative routes during periods of transport. Radio stations broadcasting traffic reports over the air undoubting may use the information as well.

To a lesser degree emergency services may verify calls for assistance, while tow trucks may benefit more from the real-time information of accidents available.

Hardware

In its simplest form a PC104 form factor with rechargeable battery pack and a GPS/Wifi module would suite the minimum requirements. A touch screen to view, mark and cancel traffic related events is needed.

In the near future a cellphone will have the required hardware for this system.

Software

Navigational software would be required to display information received from other cars, and an interface to mark traffic events as they are identified by the user, or as they are cleared.

Architecture

Firstly a open ad hoc network configuration is needed. Additionally to that a predefined port, and a protocol for communicating propagated and locally identified traffic data. A simplified Peer to peer (P2P) file sharing methodology can be used to transfer information.

Functionality to upload dynamic traffic data to a community website would enable users contribute and increase to the overall usability of the system. The duration of events can be used for statistical purposes on a national level.

The System can be extended to propagate other categories of information than dynamic traffic events, and display that information on navigational software.

Legal

The system will have the ability to propagate police activity such as roadblocks. This would be detrimental to the efforts of crime prevention.

The theoretical use of data injection to decrease the integrity of the system is possible. For example as a roadblock is identified and marked, an official at the roadblock can cancel the event on the network by merely connecting to it and canceling the event. This can be done programmatically and would allow for the success of the roadblock.

On the other hand verification, fuzzy logic or other algorithms can be used to determine the integrity of data in the event of inaccurate data injection, spamming or attempts to overload the system.

Conclusion

The ability to share non-static points of interest is plausible and achievable. In certain situations the real-time propagation of information may have a negative effect on crime prevention. Extension of the system to allow for other categories is a reality.

Unlike regular glow poi, these shine a beam of  light.  Performed by Laura Ernst.  Built by me.

It is easy to apply conditional formatting for the excel generated through POI tool. The only trick is in the third line of code – to get a sheet specific for conditional formatting

final HSSFWorkbook workbook = new HSSFWorkbook();

final HSSFSheet sheet = workbook.createSheet(“sheeName”);

HSSFSheetConditionalFormatting conditionSheet = sheet
.getSheetConditionalFormatting();

// condition is only comparision operator, so second formula will be null

HSSFConditionalFormattingRule rule1 = conditionSheet
.createConditionalFormattingRule(ComparisonOperator.GT,
“25000″, null );

HSSFConditionalFormattingRule rule2 = conditionSheet
.createConditionalFormattingRule(ComparisonOperator.BETWEEN,
“0″, “25000″ );

HSSFConditionalFormattingRule[] rules = { rule1, rule2, rule3 };

// Create pattern with red background
HSSFPatternFormatting pattern1 = rule1.createPatternFormatting();
pattern1.setFillBackgroundColor(HSSFColor.RED.index);

// Create pattern with yellow background
HSSFPatternFormatting pattern2 = rule2.createPatternFormatting();
pattern2.setFillBackgroundColor(HSSFColor.LIGHT_YELLOW.index);

This is a form of advertising I have seen mostly in California.

Svaret på alle vores spørgsmål og trængsler omkring lokalhistorisk mobilformidling kunne meget vel ligge lige her!

Her er en ny applikation som både fungerer på Google Android og nu senest også på Iphone. De applikationer der hidtil har set lovende ud, har oftest kun fungeret under Iphone. Her er en løsning til flere platforme og flere brugere.

Hvordan fungerer det så?
Telefonen kender selvfølgelig din egen position vha. den indbyggede gps-enhed. Den sammenholder din position med alle optegnelser i en wiki. I www.wikitude.me er alle artikler geotagget, altså tilføjet en geografisk position. Når du holder din telefon op og drejer 360 rundt om dig selv, kan telefonen vha. af det indbyggede kompas se hvad vej du peger telef0nen. Udfra disse to oplysninger – din position og det verdenshjørne du nu vender imod - kan den let give dig afstanden til et POI/en wikiartikel i den retning du kigger lige nu. Dette punkt kan ligge på den anden side af gaden eller det kan være 117 km. væk.

Men kig selv på denne video, som på 1:19 demonstrerer applikationen.

I dette tænkte eksempel vil du, når du står på Torvet i Køge og kigger rundt, i princippet kunne få informationer om alle husene der omkranser Torvet. Det er selvfølgelig forudsat at der er nogle der har lagt informationerne ind i systemet. I skrivende stund ligger der to tyske tekster om Køge, samt een (min) om Køge Byhistoriske Arkiv.

Ulempen – for sådan een er der jo altid – er, at der kun kan være 255 tegn i brødteksten om hvert POI. Og så kommer man til at slås om opmærksomhed med andre POI i nærheden. Brugeren vil både kunne se mere om de historiske guldkorn og de lokale cafeer, benzinstationer osv. – hvis de har lagt informationer ind. Men lige nu er der som sagt ikke trængsel om POIs i Køge.
Nå ja, så er der jo heller ikke så mange Iphones derude endnu…

Men virker det nu også ordentligt?
Ja, det ved jeg da virkelig ikke, for jeg har ikke haft lejlighed til at teste det endnu. Jeg kunne bare ikke vente med at dele dette link med Jer :-) Alt i alt er det bestemt værd at bruge lidt tid på at fifle med dette nye legetøj. Så nu mangler du (jeg) kun en Iphone, men heldigvis er julen jo lige om hjørnet!

Invece basta un esamino, un’analisi semplice semplice, un prelievo di buonsenso: come certi bambini coraggiosi ma segretamente gracili manchiamo di calcio, e anche un po’ di fosforo.

Un peccato, perché i metatarsi raffinati, quelli di Wilkinson, di Carter, di Steyn, nel rugby di oggi contano ormai quanto i polpastrelli.Gli Springboks, i campioni del mondo, quelli degli uomini macigno in mischia e dell’uomo ghepardo, Bryan Habana, all’ala, siamo riusciti a reggerli fisicamente, a pressarli per tutta la seconda metà del primo tempo, e all’inizio del secondo, prima che la folata di du Preez e la terza delle quattro mete sudafricane ci tagliasse le gambe.

Nell’economia dei se e dei ma fanno 12 punti in meno, da sommare all’insufficienza nei calci di spostamento.Nel bilancio ci sta un’Italia che si è confermata d’acciaio in mischia e che ha mostrato (finalmente!) qualche lampo in attacco.

In quei 20 splendidi minuti finali del primo tempo Zanni è arrivato a un metro dalla meta, e poco dopo oltre la linea si è tuffato Garcia, liberato in un delizioso incrocio da Gower, uno che viene dal rugby a 13: la fotocopia del giochetto che contro gli All Blacks aveva quasi mandato in meta Canale.

la Bialetti passa a Jesi, dove la Fileni cade per la seconda volta in sette giorni (ed è già la terza sconfitta in casa, prima con Reggio Emilia e poi Rimini e soprattutto è la terza sconfitta consecutiva), e finalmente si schioda dalla scomoda quota zero.

In una partita dai mille volti, prima la grande partenza della Bialetti salita anche a +14, poi il recupero Fileni, la nuova fuga di Scafati, il contro sorpasso di Jesi, e poi il finale all’ultimo respiro, è il bomber nato a Washington che ha in mano il pallone decisivo a 4″ sul 74-73 e lo usa come un killer del parquet.

Altra squadra che conferma il trend positivo la Prima Veroli, giunta alla quarta vittoria in fila, travolgendo nel secondo tempo (99-82) una Aget Imola handiccapata dai ko di Amoroso e Bolzonella, ma Veroli adesso gioca in stato di grazia e fermarla è dura per chiunque, in particlare quando ha il trio delle meraviglie scatenato: il nuovo azzeccatissimo innesto di Draper (25p., 6/8, 3/7,, 4/4 ai liberi, 5 recuperi, 3 assist), Nissim che segna da cecchino ( 21p., 5/8, 3/4) e Hines che è una cassaforte (18p., 6/6, 1/2, 9 rimb.).

Nel prossimo turno, tanta carne al fuoco: si comincia sabato con l’anticipo di Rai Sport più AB Latina-Miro Radici, una partita chiave per la lotta salvezza, e si prosegue con un interessantissimo Trenkwlader-Umana, ed anche Bialetti-Prima, Banco Sardegna-Fastweb, Enel-Snaidero, ma anche Aget-Fileni e la capolista Rimini che attende la matricola guastafeste Ucc.

Il giorno dopo l’1-1 con la Francia, costato l’eliminazione dal prossimo Mondiale all’Irlanda di Giovanni di Trapattoni, esplode la rabbia degli irlandesi per il clamoroso fallo di mano di Thierry Henry, ribattezzato ironicamente ‘Handy’ (‘manina’, ndr).

“L’eroica prestazione dell’Irlanda di Trapattoni è stata crudelmente annullata dal doppio fallo di mano di Henry”, accusa l”Irish Times.”Il gol di Thierry Henry -prosegue il quotidiano irlandese- è stato ciò che ha separato i due lati dello Stade de France, dopo una notte che rimarrà a lungo nella memoria di migliaia di persone stipate nel magnifico stadio fino al mattino presto.

L’Equipe condanna Domenech’La mano di Dio’, questo il titolo del quotidiano sportivo francese L’Equipe dopo la qualificazione ottenuta in extremis dalla Francia ai danni dell’Irlanda di Trapattoni grazie a “un enorme fallo di mano di Thierry Henry”, come lo definisce il giornale.

La federcalcio irlandese (Fai) ha chiesto la ripetizione dello spareggio mondiale contro la Francia per l’irregolarità del gol di Gallas, preceduto da un fallo di mano

Taro grows in our front yard pond along with iris, wiry rush, water hyacinth, and penny royal.

I’m working on a new pond for our backyard, a small in-ground water garden. One of the plants that I will grow in the pond will be taro or elephant ear (Colocasia esculenta). I have plenty of it growing in my larger front yard pond, and it will be a simple matter to transplant a few small corms.

Taro leaves at Plant Delight Nursery in Raleigh, NC

Taro was one of the earliest plants put into cultivation as humans began developing farming practices and domesticating plants. Thought to have been first cultivated in Malaysia and wet tropical India about 7,000 years ago, taro spread throughout the Pacific Basin to China, Indonesia, Egypt, tropical Africa, and eventually the New World in the West Indies where it was grown as food for slaves.

The Maoris took taro to New Zealand, and Indonesians carried it with them to Hawaii, where it is still cooked today into poi. The leaf of the taro, called a luau in Hawaiian, is used as a plate and gives us our name for a Hawaiian-style feast. The young leaves are also edible after 45 minutes of boiling.

This is a corm from a young taro plant. They are generally harvested at eight months for eating.

The most often used edible part of the plant is the starchy corm, which is peeled and pounded on a board with a stone until it forms a thick paste. The paste is dried, then mixed with water, kneaded and cooked into poi, a thick gelatinous paste.

Taro may be roasted, baked, or boiled, but I haven’t tried cooking it. Cooking taro is essential as the raw corms contain needle-like crystals of calcium oxalate. Cooking destroys this poisonous skin irritant.

If you’ve cooked taro, I’d like to hear about your experience, how you cooked it and what it tasted like.  Hey, if 100 million people on this planet eat it every day, and 600 million use it as a food staple, it can’t be too bad.

The women of Palau (and many other Pacific Islands) grow taro as a food staple. You can read more about how they cultivate taro at this website. http://www.pacificworlds.com/palau/land/planting.cfm

Idag saknar jag eld.

Det är bra synd att jag inte har någon fakirbild. Har lampolja hemma så får gå ut och leka lite någon dag och be Robin ta lite kort, har ju en ny fakirfackla att gosa med! Sen har jag ju ett par oanvända firefans också som ska provas, men det får bli i Jönköping för det är snäppet för kallt här uppe nu.

Pyy, saknar så många från Eldsjäl. Saknar att se er elda. Saknar att hänga i stora gympasalar med er och att hänga i skogen med er. Jag tänker inte så väldigt ofta på det, mest för att jag är här uppe och majoriteten nere i söderland, men det händer. Typ idag. Skulle kunna rabbla minnen här hur länge som helst som ingen annan än precis ni skulle förstå.

Snart ses vi folks

Back in my student days, my friend Liz introduced some of our Assent cell to the wonderousness of poi. Raz got addicted, I got addicted, and by the time Imagine rolled round one of my fave people from City Church, Kath had her own set of flag poi. I got a set in Australia and since then have taken poi to Imagine which has been a great tool to reach out to some of the youth on the fringes of the event.

I took it to Cornwall, onto the beach after the surfer’s blessing and the next thing you know this is going on…isn’t it good that the BrunetteKoala paparazzi was on hand again? Tee hee hee!

Baby T found the Daddies poi display mucho amusing…

As did me and their significant others – bring on the joy and ‘Lucy’ (Mrs Rev gor renamed when the girls informed her that she was their big sister)…and a couple from the Rev’s church who we met later that day and shared these pics from.

Who knew The State That I Am In or The Rev were closet happy clappy charismatics?!! Grace and peace to you brothers…grace and peace…because you knew this post was coming….

I’ve gone to Spin Jam a couple times, and really liked it.  (The only reason I don’t go more often is I can’t stay up that late.)

A few minutes is taken to unwind, let the day go, and just connect.  Then one room is for drumming, and another is for poi.  The poi room has a DJ.  The people are friendly.  There is lots of energy.  It is for adults only.

Da mais recente actualização da Aplicação PosiTreX – Sistema GPS de Localização de Viaturas destacamos hoje uma nova funcionalidade:

POI-Ponto de Interesse

Para definir um POI, basta posicionar o botão esquerdo do rato no local que se pretende e em simultâneo premir a letra p do teclado.
Abre-se automaticamente uma nova janela, já com as coordenadas inseridas. Finalmente, introduz-se a legenda (nome do POI) e define-se o raio de abrangência.

Associada a esta funcionalidade está a possibilidade de definir Categorias de POIs.
Podem definir-se Categorias, ie. Clientes/Obras/Localidades e associar cada POI à respectiva Categoria.
Assim, pode pesquisar-se, por exemplo, todos os POI clientes dentro da Categoria Clientes.

Para já, só funciona correctamente no Internet Explorer.

Riflescopes are mechanical contraptions. One of the sad realities about precision shooting is that, sooner or later, you will experience a scope failure. If you’re lucky it won’t happen in the middle of a National-level competition. And hopefully the failure will be dramatic and unmistakable so you won’t spend months trying to isolate the issue. Unfortunately, scope problems can be erratic or hard to diagnose. You may find yourself with unexplained flyers or a slight degradation of accuracy and you won’t know how to diagnose the problem. And when a 1/8th-MOA-click scope starts failing, it may be hard to recognize the fault immediately, because the POI change may be slight.

When An Expensive Scope Goes Bad
Recently, this editor had a major-brand 8-25×50mm scope go bad. How did I know I had a problem? Well the first sign was a wild “drop-down” flyer at a 600-yard match. After shooting a two-target relay, I took a look at my targets. My first 5-shot group had five shots, fairly well centered, in about 2.2″. Pretty good. Everything was operating fine. Then I looked at the second target. My eye was drawn to four shots, all centered in the 10 Ring, measuring about 2.4″. But then I saw the fifth shot. It was a good 18″ low, straight down from the X. And I really mean straight down — if you drew a plumb line down from the center of the X, it would pass almost through the fifth shot.

That was disconcerting, but since I had never had any trouble with this scope before, I assumed it was a load problem (too little powder?), or simple driver error (maybe I flinched or yanked the trigger?). Accordingly, I didn’t do anything about the scope, figuring the problem was me or the load.

But, at the next range session, things went downhill fast. In three shots, I did manage to get on steel at 600, with my normal come-up for that distance. Everything seemed fine. So then I switched to paper. We had a buddy in the pits with a walkie-talkie and he radioed that he couldn’t see any bullet holes in the paper after five shots. My spotter said he thought the bullets were impacting in the dirt, just below the paper. OK, I thought, we’ll add 3 MOA up (12 clicks), and that should raise POI 18″ and I should be on paper, near center. That didn’t work — now the bullets were impacting in the berm ABOVE the target frame. The POI had changed over 48″ (8 MOA). (And no I didn’t click too far — I clicked slowly, counting each click out loud as I adjusted the elevation.) OK, to compensate now I took off 8 clicks which should be 2 MOA or 12″. No joy. The POI dropped about 24″ (4 MOA) and the POI also moved moved 18″ right, to the edge of the target.

For the next 20 shots, we kept “chasing center” trying to get the gun zeroed at 600 yards. We never did. After burning a lot of ammo, we gave up. Before stowing the gun for the trip home, I dialed back to my 100-yard zero, which is my normal practice (it’s 47 clicks down from 600-yard zero). I immediately noticed that the “feel” of the elevation knob didn’t seem right. Even though I was pretty much in the center of my elevation (I have a +20 MOA scope mount), the clicks felt really tight — as they do when you’re at the very limit of travel. There was a lot of resistance in the clicks and they didn’t seem to move the right amount. And it seemed that I’d have four or five clicks that were “bunched up” with a lot of resistance, and then the next click would have almost no resistance and seem to jump. It’s hard to describe, but it was like winding a spring that erratically moved from tight to very loose.

At this point I announced to my shooting buddies: “I think the scope has taken a dump.” I let one buddy work the elevation knob a bit. “That feels weird,” he said: “the clicks aren’t consistent… first it doesn’t want to move, then the clicks jump too easily.”

Convinced that I had a real problem, the scope was packed up and shipped to the manufacturer. So, was I hallucinating? Was my problem really just driver error? I’ve heard plenty of stories about guys who sent scopes in for repair, only to receive their optics back with a terse note saying: “Scope passed inspection and function test 100%. No repairs needed”. So, was my scope really FUBAR? You bet it was. When the scope came back from the factory, the Repair Record stated that nearly all the internal mechanicals had been replaced or fixed: “Replaced Adjustment Elevation; Replaced Adjustment Windage; Reworked Erector System; Reworked Selector; Reworked Parallax Control.”

How to Diagnose Scope Problems
When you see your groups open up, there’s a very good chance this is due to poor wind-reading, or other “driver error”. But my experience showed me that sometimes scopes do go bad. When your accuracy degrades without any other reasonable explanation, the cause of the problem may well be your optics. Here are some of the “symptoms” of scope troubles:

1. Large shot-to-shot variance in Point of Impact with known accurate loads.
2. Uneven tracking (either vertical or horizontal).
3. Change of Point of Impact does not correspond to click inputs.
4. Inability to zero in reasonable number of shots.
5. Unexpected changes in needed click values (compared to previous come-ups).
6. Visible shift in reticle from center of view.
7. Changed “feel” or resistance when clicking; or uneven click-to-click “feel”.
8. Inability to set parallax to achieve sharpness.
9. Turrets or other controls feel wobbly or loose.
10. Internal scope components rattle when gun is moved.

Source of Problem Unknown, but I Have a Theory
Although my scope came with a slightly canted reticle from the factory, it had otherwise functioned without a hitch for many years. I was able to go back and forth between 100-yard zero and 600-yard zero with perfect repeatability for over five years. I had confidence in that scope. Why did it fail when it did? My theory is side-loading on the turrets. I used to carry the gun in a thick soft case. I recently switched to an aluminum-sided hard case that has pretty dense egg-crate foam inside. I noticed it took some effort to close the case, though it was more than big enough, width-wise, to hold the gun. My thinking is that the foam wasn’t compressing enough, resulting in a side-load on the windage turret when the case was clamped shut. This is just my best guess; it may not be the real source of the problem. Remember, as I explained in the beginning of this story, sometimes scopes — just like any mechanical system — simply stop working for no apparent reason.

Probabil sunt destui cei care nu contribuie la OSM nu din lipsă de timp cu pur și simplu pentru că modul de editare al hărții li se pare prea dificil. Pentru aceștia am să încerc să prezint aplicații care fac contribuția la OSM cât mai ușoară.

Prima modalitate necesită un iPhone. Aplicația Mapzen POI Collector realizată de Cloudmade va fi disponibilă în curând și va oferi posibilitatea de a adăuga puncte de interes în peste 150 de categorii. Așadar indiferent că mergeți seara în baruri cu prietenii, sau poate la un bowling, sau pe munte cu gașca, veți putea contribui la OpenStreetMap.

Viitorul sună bine!

The Apache POI team is doing an amazing job at making Microsoft Office file formats more accessible to the open source Java world. One of the projects that benefits from their work is Apache Tika that uses POI to extract text content and metadata from all sorts of Office documents.

However, there’s one problem with POI that I’d like to see fixed: It’s too big.

More specifically, the ooxml-schemas jar used by POI for the pre-generated XMLBeans bindings for the Office Open XML schemas is taking up over 50% of the 25MB size of the current Tika application. The pie chart below illustrates the relative sizes of the different parser library dependencies of Tika:

Both PDF and the Microsoft Office formats are pretty big and complex, so one can expect the relevant parser libraries to be large. But the 14MB size of the ooxml-schemas jar seems excessive, especially since the standard OOXML schema package from which the ooxml-schemas jar is built is only 220KB in size.

Does anyone have good ideas on how to best trim down this OOXML dependency?
