Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

1. On-demand self-service: every consumer will be able to unilaterally provision multiple computing capabilities like server time, storage, bandwidth, dedicated RAM or CPU without requiring any sort of human interaction from their respective Cloud providers.
2. Rapid elasticity and scalability: all the computing capabilities outlined above can be elastically provisioned and released depending on how much demand my company will have in a specific period of time. Suppose the X company is launching a new product today and it expects a very large number of customers. The X company will add more resources to their Cloud for the very first days (where they suppose the load to be very high) and then it ll scale the resources back as they were before. Elasticity and scalability permit the X company to improve and enhance their infrastructure when they need it with an huge saving in monetary terms.
3. Broad network access: capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations).
4. Measured service: Cloud systems allow maximum transparency between the provider and the consumer, the usage of all the resources is monitored, controlled, and reported. The consumer knows how much will spend, when and in how long.
5. Resource pooling: each provider s computing resources are pooled to serve multiple consumers at the same time. The consumer has no control or knownledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
6. Resources price: when buying a Cloud service make sure the cost for two units of RAM, storage, CPU, bandwidth, server time is exactly the double of the price of one unit of the same capability. An example, if a provider offers you one hour of bandwitdh for 1 Euro, the price of two hours will have to be 2 Euros.

1. It is sad when a good person decides to commit suicide
2. It is even sadder anyone writing on a subject like this MUST add this kind of disclaimers in the hope the message of the writing isn't distorted because we are unable to listen to each other without suspecting/blaming the other of pure evilness/lack of compassion.

Why is the shift on perturb done after its first use? In my experiments (using 32-bit width everywhere), for the pathological case of an 8-element (i = 3) table with three entries 0, 0x40000000 and 0x800000000, the second round yields 1 for all three, so it cannot have to do with the upper bits. My lookup looks like:

	mask = 2  - 1;
	j = perturb = hash(key);
	goto find_first_slot;
	 find_next_slot:
	j = (j << 2) + j + perturb + 1;
	perturb >>= PERTURB_SHIFT;
	/* FALLTHROUGH */
	 find_first_slot:
	entry = table[j & mask];
	if (!match(entry)) goto find_next_empty_slot;
 

This means that my first check is always the bare hash (so only do it if needed is no reason) and, since I m using gotos, I could just move the perturb >>= PERTURB_SHIFT; line before the line recalculating the next j to use. This seems to make more sense, even in the face of Python. (I actually looked at the Python file s comments again today because I thought to use a different resolution, but they have a good rationale for using the multiplication by 5.) Why can t we just use i as the PERTURB_SHIFT? Sure, this changes a shift-right by a constant, which can possibly be encoded as immediate value in assembly (unless you re on a pre-80186, which can only do SHR AX,1 and SHR AX,CL but not SHR AX,4, but that s outside of mksh s scope) into a right-shift by a variable, but i is already known, and I think the behaviour is better (it wouldn t eat any bits; assume the same 8-entry hashtable and pathologic keys 0, 8 and 16). Again: who do I think I am to go against the wisdom of the Python people, who seem to have shed more thought on this than everyone else I saw, asked, read about (including Spammipedia). That s why I m asking here. On that reference: I don t support spammers or people nagging for donations or premium accounts, like Xing and Groundspeak/Geocaching.COM, at all. In fact, I urge others to do the same, so it really hurts them; it may be their business model, but not if they spam me. Besides, OpenCaching.DE exists. Another thing is: to avoid CVE-2011-4815, I m randomising the hash used, with one seed value per hashtable, changed before a resize operation. I originally thought to seed it with nonzero, but then I have to rehash on hashtable resize, so I ll be XORing the final hash value instead (thanks ciruZ for the idea). I m thinking of omitting that for indexed arrays, as an attacker almost certainly cannot determine the keys there. (To directly use the indexed array keys, which are already uint32_t, as hashes makes using i from even more important.) The hash I m using is a modified Jenkins one-at-a-time called NZAAT: it s my new generic standard n n-cryptographic hash, and the changes are thus: while adding a byte, another increment of the hash is done (so NUL counts), and the finaliser got prefixed with the shift-left-add+shift-right-xor sequence of the adder (but not adding any value or the +1), to get best avalanche for all bytes. I actually compiled several versions of Hash.cs on a Windows VM at work to analyse the original one-at-a-time and all of my modifications; these turned out to be the simplest ones (I originally had added 0x100 instead of 1, but the effect was the same, and +1 is usually cheaper on most CPUs). Also, to avoid people being able to get to the seed, a user will always get only a sorted list of hashtable keys (numeric for indexed arrays, ASCIIbetically otherwise; see also my thoughts on JSON from the previous wlog entry). What algorithm do I use? For strings, comparisons are much more expensive, so I d like to keep them low. Memory use is also a factor; allocating one large(r) block is better than many small ones due to the pool allocator overhead and due to portability to ancient Unic s (which is another reason for me to use a hashtable which is a small struct plus an array of pointers, and then pass the list of keys as array of string pointers, instead of a tree). For both reasons, I m thinking a relatively simple MergeSort: I need to allocate the result array anyway, so I can just get two and free the one that isn t the end result, and it s AFAICT the cheapest on comparisons other than Tree Sort (which nobody really seems to use, and which would effect to using a balanced binary tree again). Since keys are unique, stability and duplicate handling is never an issue. I d like to use only one algorithm and one data structure, not a combination, as compactness is a design goal. Please drop your thoughts on Freenode, e.g. by /msg MemoServ send mirabilos your text here or per eMail to the domains debian, freewrt or mirbsd, which are organisations, with the localpart tg. Or just contact me as usual, if you re already acquainted. Or lookup 0xE99007E0. Thanks in advance! (Especially, Python Developers thoughts are welcome.)

• I gave them a full explanation on how they could manually check this using openssl. I showed them the canonical versions of all the XML parts, and how to check that it's valid. I showed the fingerprint of my certificate and how that was the same as on the website.
• They replied saying that I either didn't upload a certificate or that it was expired, or that I did something else weird I didn't even understand.
• I found that the ideal standard says there is a limit of 5 years for certificates while their documentation says to generate one for 10 years. So I uploaded a new certificate but that didn't help, and said so.
• They replied back that my self-signed signature should have been one using sha256 and not sha1. This makes little sense for a self-signed certificate. The iDEAL standard does say that the signature needs to use at least sha256 in case you don't use a self-signed certificate though.
• So I mailed them back saying I created a new certificate with a sha256WithRSAEncryption signature algorithm, but that I still have the same problem.
• They mail me back saying I have an invalid certificate and that I should read the manual and they can't help me. They give no indication on exactly was is invalid about the certificate, just that it's invalid.
• So I say that I follow all requirements of the standard and used the commands they provided.
• They reply back that they checked the logs and that we're using the old version and that we should switch to the new version of iDEAL. Of course I'm using the new version and am sending this to the correct URL.
• They provide software (no license mentioned) in php, java and .NET. But that's of course is not integrated in anything, it's just the library to do the calls. So I tried the php version and send a request using the same certificate and actually do get a reply back now. Both my version and the php generated version properly verify.
