Finally got to lesson 7 and learnt how to say where I wanna eat.

[Michael] Hello. How are you?

[M] Shalom. Ma shlomeh?

[Rachel] Hey. I am fine. How are you?

[R] Shalom. Ani beseder. Ma shlomha?

[M] Ok, thanks. What do you wanna do? Do you want to eat something with me?

[M] Beseder, toda. Ma-at rotsa laasot? At rotsa leehol mashehun iti?

[R] Yes, I want to eat something with you, but I also want to drink something.

[R] Kin, ani rotsa leehol mashehun ithra, aval ani rotsa lishtot mashehun.

[M] I also want to eat with you. Where do you want to eat?

[M] Gam-ani rotse leehol itah. Eifo at rotsa leehol?

[R] Not here. At a restaurant at the hotel Hilton on Rabin street. There.

[R] Lo po. Ba-misada be-malon Hilton, be-rehov Rabin. Sham.

[M] I also want to drink something, some wine, or some beer. When? What hour do you want to eat at?

[M] Ani gam-rotse lishtot mashehu, ctsat yayn, o ctsat bira. Matai? B-eize sha-a at rotsa leehol?

[R] Be-sha-a ahat or be-sha-a shtey. Beseder? Ata rotse leehol aruha tsororaim?

[M] No, it’s not ok. I want to buy something now, here. I want to eat later, at 8 or 9 o’clock. Is it ok for you?

[M] Lo, lo-beseder. Ani rotse liknot mashehu ahshav, po. Ani rotse leehol euter meuha, be-sha-a shmone or be-sha-a tesha. Beseder?

26-27 Martie – Final Frontier. Muzeul Taranului Roman, Sala Oaspeti Şoseaua Kiseleff 3, Bucureşti

M-a dus azi tiranul. Nici nu stiam de eveniment, desi a fost organizat de sotia unui prieten. Multe carti SF, am vazut multe editii Dune, unele mai noi, altele mai vechi, nelipsitul Orson si multe-multe altele. Standuri de BoardGames si blogbooks. Maestri Jedi si Dark Vader costumati umbland pe-acolo.

Si cireasa de pe tort: RoboFun robots sumo fight contest. Au fost vreo 16 roboti participanti (daca tin eu bine minte) si s-au luptat pe ring. Nu mai stiu cine a castigat, ca tot concursul a durat 2 ore si am plecat dupa vreo ora sa mananc ceva de pranz/dimineata. Mi-a placut sa-i revad pe amicii mei si ma bucur sa stiu oameni din astia super activi si pasionati. Sper sa ne intalnim la un boardgame curand.

Ah, deznodamantul meu: 105 ron : 2 carti (din care pe una deja am citit-o pe nerasuflate) si un joc.

The House on the Borderland – de William Hope Hodgson – pe care nu am putut-o lasa din mana pana la final – geniala!

O colectie de istorii de H.P.Lovecraft, printre care si The Call of Cthulhu.

Si Black Stories de Holger Bosch, pe care sper sa-l joc cat mai curand cu prietenii.

Me happy!

2011-05-01 Bucharest Arenele Romane Romania
Address: Parcul Carol.

high-school old times, songs that I grew up with 🙂

Tomorrow will take us away
Far from home
No one will ever know our names
But the bards’ songs will remain
Tomorrow will take it away
The fear of today
It will be gone
Due to our magic songs

 

Helloooo, agaaainnn!!! Long time no see, 4G

Let’s have a short (very short) talk about this DAF thinggie. DAF stands for Dual Address Bearer and it is a flag only set in the Create Session Request message, sent from the MME to the SGW, over the S11 interface. Details about this funky flag are in TS 23.401 (Section 5.3.2.1 E-UTRAN Initial Attach and Section 5.3.1 IP Address Allocation) and in TS 29.274 (Table 7.2.1-1 Information Elements in Create Session Request) and…might be in other TSs also, but I have no idea about those 😛

So, when and why we do use this flag? Mwell, TS 29.284 says the following:

DAF – Conditional :  Dual Address Bearer Flag: This flag shall be set to 1 when the UE requests a PDN type IPv4v6 and all SGSNs which the UE may be handed over to support dual addressing. This shall be determined based on node pre-configuration by the operator.

So, this flag is an indication sent from the MME to the SGW, telling the SGW at the moment of the Initial Attach procedure: Hey! you know what? My mobile device supports dual-stack. You can assign it at once, on the same bearer, both an IPv4 and an IPv6.

Also, if the UE moves from a 3G coverage to a 4G coverage (the definition above says the other way around, but logic tells me that the MME actually sends a Create Session Request when it is a _target_ MME, therefore when the UE moves from a 3G to a 4G network), doing an MME relocation, SGW relocation handover procedure, our MME would says the following to its fellow SGW: Dear SGW, my mobile device has just arrived here from a 3G network, more specifically from an SGSN that supports dual addressing. So don’t worry that I am asking for both an IPv4 and IPv6 addresses for the same bearer for this UE.

Now, there are several rules when using or not this DAF. The general rule is to set it, which seems to be the default rule in the 4G network context.

The only case when, in a 4G context we do NOT set this flag is when the interface between the SGW and the PGW (the S5/S8 interface) runs PMIP, and not GTPv2 (as S11 does).

So, usually, in this most common case, the UE that supports dual-stack will ask for a single default bearer, having an IPv4v6 dual-stack type of address. If the MME is running in a full 4G environment or it is aware that all SGSNs to which the user may handover to also support dual-stack and the MME is aware that the S5/S8 interface runs GTPv2, then the MME will set the DAF flag and hopefully the PGW also supports dual-stack, our dear UE will get an IPv4v6 address, actually meaning that it will get 2 IP addresses (one IPv4 and one IPv6) for the same, single, default bearer to this  APN.

But, even if the UE says it supports dual-stack, but the MME considers, for some reasons it has (it is aware of non-compatible SGSN, or it knows about S5/S8 running PMIP or whatever), not to set the DAF flag, then the UE’s type of address remains to be decided by the PGW….as it follows:

The PDN GW takes into account the received PDN type, the Dual Address Bearer Flag and the policies of operator when the PDN GW selects the PDN type to be used as follows. If the received PDN type is IPv4v6 and both IPv4 and IPv6 addressing is possible in the PDN but the Dual Address Bearer Flag is not set, or only single IP version addressing for this APN is possible in the PDN, the PDN GW selects a single IP version (either IPv4 or IPv6). If the received PDN type is IPv4 or IPv6, the PDN GW uses the received PDN type if it is supported in the PDN, otherwise an appropriate error cause will be returned. The PDN GW allocates a PDN Address according to the selected PDN type. If the PDN GW has selected a PDN type different from the received PDN Type, the PDN GW indicates together with the PDN type IE a reason cause to the UE why the PDN type has been modified.

What about the UE. What should it do after getting an IP?

After the Attach Accept message and once the UE has obtained a PDN Address, the UE can then send uplink packets towards the eNodeB which will then be tunnelled to the Serving GW and PDN GW. If the UE requested for a dual address PDN type (IPv4v6) to a given APN and was granted a single address PDN type (IPv4 or IPv6) by the network with a reason cause indicating that only single IP version per PDN connection is allowed sent together with the PDN type, the UE may request for the activation of a parallel PDN connection to the same APN with a single address PDN type (IPv4 or IPv6) other than the one already activated. If the UE receives no reason cause in step 18 in response to an IPv4v6 PDN type and it receives an IPv6 Interface Identifier apart from the IPv4 address or 0.0.0.0 in the PDN Address field, it considers that the request for a dual address PDN was successful. It can wait for the Router Advertisement from the network with the IPv6 prefix information or it may send Router Solicitation if necessary.

Now, the applications on the UE must know which type of socket to create. They can either create an IPv4 or an IPv6 socket and choose among the available IP addresses.

I’ve just finished the first 6 lessons. Now let’s try to imagine a conversation that I would have, in order to practice my newly learned words…or at least some of them. The conversation is a bit weird, but at least it contains the words I should have learned.

Also, don’t be scared about the writing – speech transcription 😦 I wish I start to learn writing soon!!!

Michael and Rachel are 2 good friends. They meet and talk:

[M] Hello, Rachel! How are you?

[M] Shalom, Rahel. Ma shlomeh?

[R] Hey, Michael. I’m fine, thanks, and how are you?

[R] Shalom, Mihael. Tov, toda, ve-ma shlomha?

[M] Not so good.

[M] Lo kolkah-tov.

[R] Do you know where Isaia street is?

[R] Ata iodeea eifo rehov Ieshaiau?

[M] Yes, it is there.

[M] Kin, ze sham.

[R] Do you know where Rabin square is? Is it not here.

[R] Ata iodeea eifo kikal Rabin? Ze lo po.

[M] I don’t know. It is not there.

[M] Ani lo iodeea. Ze lo sham.

[R] I want to eat something. Do you want to eat something also?

[R] Ani rotsa leehol mashehu. Ata rotse gam leehol mashehu?

[M] I don’t want to eat. But I want to drink something. Where do you want to eat?

[M] Ani lo rotse leehol. Aval-ani rotse lishtot mashehu. Eifo at rotsa leehol?

[R] At my place.

[R] Ets-li.

[M] At your place? I don’t want to.

[M] Ets-leh? Ani lo rotse.

[R] Where do you want to drink? At your place?

[R] Eifo ata rotse lishtot? Ets-ha?

[M] I want to eat at my place. When do you want to eat?

[M] Ani rotse leehol etsi. Matai at rotsa leehol?

[R] Not now. Later. I also want to drink something, please.

[R] Lo ahshav. Ioter meuha. Ani rotse gam lishtot mashehu, bevacasha.

[M] Yes. Me too.

[M] Kin, gam-ani.

…..

[R] Goodbye. See you.

[R] Shalom. Lehit-raot.

[M] Goodbye. See you.

[M] Shalom. Lehit-raot.

That was it 😛 At least now I can ask for directions and food and drink. Of course, I’ll have to be careful on WHERE I am going to eat and drink 😀

Nu pentru vreo ocazie, ci pentru ca nu ma pot abtine 😀

Mi-a luat azi tiranul El Emperador, Chile, alb. La pretul la care este, cred ca e cel mai bun vin pe care l-am baut in Romania (unde singurul termen de comparatie la capitolul vinuri demi-seci, albe, usor de tot acidulate si cu aroma potrivita e un Pinot Gris care se face in Alsacia-Haut-Koenigsbourg, si pe care am avut ocazia sa-l incerc acum vreo 5 ani, prin amabilitatea directorului muzeului de transporturi si telecomunicatii de acolo – Alsace Tradition – Pinot Gris – cred ca asta e … ). Nici prea acidulat, si aromat, demi-sec, dar nu iti ramane gura uscata dupa ce bei.

believe there’s morality above any law, which must stand watchdog on all attempts as unchanging regulation.

Democracy is susceptible to being led astray by having scapegoats paraded in front of the electorate. Get the rich, the greedy, the criminals, the stupid leader and so on ad nauseam.

Power corrupts, absolute power corrupts absolutely. But: power attracts the corruptible.

Face your fears or they will climb over your back.

Ani mevina Hivrit == I understand Hebrew – a woman saying that

Ani mevin Anglit == I understand English – a man saying that

At mevina Hivrit? == Do you understand Hebrew? – addressing to a woman

Ata lo mevin Anglit == You do not understand English. – addressing to a man

I can hardly wait to learn how to _write_ these 😀

Sliha  == Excuse me.

Bent double, like old beggars under sacks,
Knock-kneed, coughing like hags, we cursed through sludge,
Till on the haunting flares we turned our backs,
And towards our distant rest began to trudge.
Men marched asleep. Many had lost their boots,
But limped on, blood-shod. All went lame, all blind;
Drunk with fatigue; deaf even to the hoots
Of gas-shells dropping softly behind.

Gas! GAS! Quick, boys! — An ecstasy of fumbling
Fitting the clumsy helmets just in time,
But someone still was yelling out and stumbling
And flound’ring like a man in fire or lime.—
Dim through the misty panes and thick green light,
As under a green sea, I saw him drowning.
In all my dreams before my helpless sight
He plunges at me, guttering, choking, drowning.

If in some smothering dreams, you too could pace
Behind the wagon that we flung him in,
And watch the white eyes writhing in his face,
His hanging face, like a devil’s sick of sin,
If you could hear, at every jolt, the blood
Come gargling from the froth-corrupted lungs
Bitter as the cud
Of vile, incurable sores on innocent tongues, —
My friend, you would not tell with such high zest
To children ardent for some desperate glory,
The old Lie: Dulce et decorum est
Pro patria mori.

Am terminat primele 5 carti.

Bureaucracy destroys initiative. There is little that bureaucrats hate more than innovation, especially innovation that produces better results than the old routines. Improvements always make those at the top of the heap look inept. Who enjoys appearing inept? — A Guide to Trial and Error in Government, Bene Gesserit Archives

Good government never depends upon laws, but upon the personal qualities of those who govern. The machinery of government is always subordinate to the will of those who administer that machinery. The most important element of government, therefore, is the method of choosing leaders. — Law and Governance, The Spacing Guild Manual

Bene Gesserit were old. Even though they appeared young, they were the oldest being still alive. Mii de vieti intr-una singura, una dupa alta, transmise in alt corp, adunate una peste alta, un pachet de cunostinte disponibil unei singure persoane. Cunostintele si experienta a mii de oameni, conducatori bine alesi de-a lungul miilor de ani. Cum e sa arati tanar si sa iti urmezi viata in ritm cu a celor din jur, dar pe dinauntru sa fii batran, de mii de ani, sa privesti de multe ori lumea ca prin deja-vu, sa stii aceleasi pattern-uri batatorite de oamenii din jurul tau. Nu e nimic nou, totul e plictisitor si previzibil. Ai face orice sa dai de ceva _nou_. Nu era superioritate, ci doar stagnare.

Much that was called religion has carried an unconscious attitude of hostility toward life. True religion must teach that life is filled with joys pleasing to the eye of God, that knowledge without action is empty. All men must see that the teaching of religion by rules and rote is largely a hoax. The proper teaching is recognized with ease. You can know it without fail because it awakens within you that sensation which tells you this is something you’ve always known.

Paradox is a pointer telling you to look beyond it. If paradoxes bother you, that betrays your deep desire for absolutes. The relativist treats a paradox merely as interesting, perhaps amusing or even, dreadful thought, educational.

Once men turned their thinking over to machines in the hope that this would set them free. But that only permitted other men with machines to enslave them.
