Some time in the last few months, I remember reading something of a rant about how difficult it was to add features to Oracle - something about having tests run for hours to days, hundreds of feature flags, causing completely random things to break, having to add hundreds of your own tests, and having to wait weeks for management approval after additional testing.
However, I can't seem to find it anymore. The only other clue I have is that I got to it through a link from the "Daily News" email.
I tried searching on the site, but I can't seem to find it.
It doesn't sound familiar to me; I'm guessing it came somewhere other than the insider news.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I’ve replaced spinning hard drives (HDD) for SSDs in several computers recently and the difference is amazing. An SSD on a SATA interface is about 10 times faster than a 7200rpm HDD and about 13 times faster than a 5400rpm drive. On my wife’s 2012 laptop (Intel i3-2350M CPU running at 2.3 GHz with 4GB of DDR3-1333), I replaced the original 5400rpm HDD with an SSD and the computer is around 10 times faster. It boots in seconds rather than minutes (Windows 10 Home) and there’s no waiting for web pages to load, no pauses in videos, and so on. I’ve now done the same thing for three of her friends. Prices on good SSDs are incredibly low on Amazon right now. I’ve been using Samsung 860 EVO or SanDisk Extreme Pro SSDs.
To make the swap, you typically need just three things. The new SSD, a USB 3.0 external disk enclosure and disk cloning software. USB 3.0 enclosures from Sabrent or Inaco are in the $10 range. I’ve used the free versions of EaseUs Todo Backup or Aomei Backupper or Acronis TrueImage to do the cloning. Put the new SSD in the enclosure, clone your existing drive to the SSD and swap out the HDD. A serendipitous advantage is that, after the swap, you can put the old hard drive in the enclosure and use it for backups. Total cost can easily be under $100 depending on the size SSD you need.
With GHz CPUs and memory, if you're still running off a HDD, you're probably losing 75% or more of your computer's potential.
Note: I just refurbished by own desktop computer with an Intel H270 chipset motherboard and an M.2 SSD with a PCIe x4 interface (Samsung 960 EVO). The configuration is 3 times faster than hooking an SSD up to SATA, but you need a compatible motherboard and SSD, obviously.
2 things are dead now. ICE cars and mechanical drives. More so mechanical drives but yeah, it is truly beyond anything else, the #1 speed up shop in the arm you can do for your pc today.
The greater question is this today: With laptop manufactures falling all over themselves with hybrid drives, optane memory cache, and split ssd/mechanical drive setups all because windows 10 is soo doggy slow about starting up, what the heck is windows 10 doing? Where is the outrage?
first thing to do on windows is disable superfetch service, especially if you have SSD, but even on spinners it would be no longer useful [even if it did work properly].
- at startup it's supposed to load up as many of your "often used apps" into memory as can fit, problem is it's nearly always loading up important windows appsreally stupid crap such as wordpad (which for me I might use once every 2 years or less) Of course it kicks out that crap when you use something like visual studio starts up, but guess what happens when you exit vs...
- theory is sound, saves loading the apps later [when used] from slow hard disks, but today, even if you are on spinners which in this case are too way fast enough, it's irrelevant
- yet MS still includes and enables it even on win 10, even if you have SSD.
- It's useless, it actually slows you down!
something else I noticed:
* windows: when I left my PC on doing nothing (say a lunch break) the hdd light would regularly flicker, every few seconds briefly and about once a minute longer for a second or more (also network activity at about the same rate)
... what is it doing??
- not saying it's all spying (this was in win 7 too), but there is that
- yes background maintenance, but why does it reload it and [re]perform the checks every time?
* linux: leave it alone and it barely ever flickers, and way less net traffic. [smart enough to leave it loaded if nothing else requires the mem, smart enough to leave it's last-run data loaded.]
short explanation: windows inner core design and yes: even a lot of it's actual kernel code, is still based on hardware from the 1970's, windows 10 is NOT a new OS, it's crap on top of an old one (that relies almost exclusively on new hardware base speed (not code) to be "better than before.")
Summary: don't blame windows for being bad, instead blame it for being VERY outdated.
for those that want something to picture:
steam engines built 100+ years ago still work fine, doesn't mean they should be [given a fresh coat of paint and] used for hauling cross continental passengers and freight though does it?
... this is exactly what you have with windows.
I wonder: How can you see that wordpad, which you might use once every 2 years, is prefetched?
I wonder: How will the computer be slowed down when overwriting pages and page table entries referring to some other application (such as wordpad) as compared to overwriting zeored entries?
I wonder: Which hardware from the 1970's affects the Windows design? And in which ways? It can well be argued that the Windows 3.x software memory management was very strongly influenced by the 386 hardware MMS, and at lest on the design level could have been put onto the 386 more or less directly. But at that time, MS was striving to make Windows available on all sorts of processors, so they abandoned essential parts of the 386 MMS in favor of a single, flat memory model that was generally available on all relevant CPUs.
What is true is that MS has taken backwards compatibility to extremes (in my opinion): Read Raymond Chen's selections of blogposts from The New Old Thing[^] - quite a few of the (sometimes rather funny) stories he tells have to do with backwards comptatibilty. In contrast to people writing open software in their spare time, MS has to support their existing customer base. As a programmer, I wished that 32 bit Windows would have a thoroughy cleaned-up API (from the 16 bit version), since it couldn't be 100% compatible anyway. We didn't get that - but we got thousands of Windows applications ported from 16 to 32 bits in a few months, because MS decided to bring the API changes to a minimum, to simplify porting. From a marketing point of view (and even more the wiew of independent software vendors making Windows apps, rather than MS itself), I can fully defend that decision. What goes on under the hood is a completely different matter.
wonder: How can you see that wordpad, which you might use once every 2 years, is prefetched?
well, look in \windows\prefetch, and there it is. I even see sidebar - which I never used and in fact disabled years ago. I'm really glad ms has my best intentions in mind loading those important apps.

Umm, it's slowed down because it's loading that say wordpad from the disk into memory, and when I exit visual studio, it loads it back again
and hence, superfetch is useless. even if you have spinners it really should be disabled. If you have SSD it's almost important to disable it. (and despite some claims it does not auto disable if it sees SSD - that's just another myth.)

glad you agree with me: "a single, flat memory model ... all relevant CPU's" which includes the 186, 286, 386..., and are they not from the 70's? so yes, it's [your words] using a single model that supports all architectures thus including 70's and thus not able to make use of optimizations of later CPU's.
yes, sure, it's for backwards compatibility, and yes for backward compat, but really what's the point? there's features of w7 and beyond the 80286 will not handle, so why leave an outdated major core function that by design of other parts of the system is actually irrelevant?? (and how can ms claim w10 is an entirely new OS when it's core is that old?).
anyway just glad we and agree and your input to further detail it for others.
