| Mr Flibble <flibbleREMOVETHISBIT@i42.co.uk>: May 04 03:48PM +0100 Hi! Yesterday a significant milestone was reached in neoGFX's implementation: rendering frames at a rate of 450 FPS; this is confirmation that the design of neoGFX's architecture is sound.

In one way this is good, in the sense that a game app's available time won't be used up in rendering, or (hopefully) shuffling data to GPU. However, do you actually have a monitor with 450 Hz or better refresh rate? I find the movie refresh rates of 23.something to be generally somewhat jerky, and /very/ jerky, annoyingly and possibly physically dangerously jerky, for sideways panning, unless that panning is ultra slow. Based on the generally only slight jerkiness of 23.something I gather that for most people 70Hz should yield mostly smooth "moving pictures". The refresh rate of my old Asus MX270 monitor is 59p Hz. I don't know what the "p" signifies, there's also 59 iHz. But I guess it means 59. But 450Hz would be overkill, unless one plans for the future of robots and enhanced humans? - Alf |

By itself it's meaningless, as it depends on the complexity of the scene being rendered. From what I can see of the screenshot, it doesn't look very complex - a few hundred triangles possibly, assuming the background is animated and not just a static texture. |

That 59 Hz is perhaps measured somehow to be such that most people do not notice any jerkiness. From scientific papers I have read that calm humans can recognize images seen for ~13 milliseconds, (so 70 Hz). When nervous and alert it can reduce to ~8 milliseconds (so 120 Hz). So maybe some very passionate gamers can benefit from 120 Hz display and up from there we have to upgrade our species somehow. |

In TVs the P would be progressive scan - the electron beam tracks down the pictures once for each frame (59 times a second in this case) I is for interlaced - the beam does half the lines, then goes back and does the other half. This was especially good for European PAL and SECAM TV which ran at 25Hz, interlaced - so there was actually half a frame at a time, but the halves came out at 50Hz. Less jerky. (US NTSC was 30Hz, interlaced) Andy |

Well, I guess that's in the same category as why can't they make higher resolution scroll wheels on mouses, or why are they still putting auto-repeat before buffering on all keyboards, and why caps lock, and. And WHY only 23.x FPS?!?

This is still correct for video modes today in camcorders and streaming formats; see e.g. https://en.wikipedia.org/wiki/1080p https://en.wikipedia.org/wiki/1080i for Full HD video. Digital image chips also need readout and if they don't have the so called "global shutter mode", the lines are read in sequence - leading special motion blur artifacts for fast horizontal motion.

| rick.c.hodgin@gmail.com: May 03 06:27PM -0700 There's a day coming when the rapture will take place. Those who have acknowledged their sin, repented, asked forgiveness from Jesus Christ, will LEAVE THE WORLD at that time. They will shed this flesh- based existence and begin, in Heaven, their time in eternity in while a 7-year period of time called The Great Tribulation takes place on Earth. What will those seven years be like? Most will die. It will be like no other time in history in terms of devastation and disaster. It is the time of "Jacob's Trouble" where God puts His attention back on the Jews and pours out His wrath upon the wickedness and sin in the world. 144,000 "new Christians" (who are Jews today) will be engaged after the rapture. They will go forth and teach the message having signs and wonders during that time. For those wondering the full extent of what's coming, and why these warnings go forth today, that you should come out from the evil and wicked ways of this world and ask Jesus to forgive YOU and YOUR SIN TODAY, and thereby escape the coming wrath, watch these videos. It's a 20-part series. He's only published 19 parts as of the time of this writing. Part 20 will be posted soon. Revelation https://www.youtube.com/watch?v=dafLJ90zCyI&list=PLSP1IO9h3J7tcJ6JfNFkYUi1AM6UcXfvC You are loved. You have an eternal purpose. God will forgive your sin today, and save you from the coming wrath. Ask Him to forgive your sin today and enter in to eternal life. Time is short. The time to ask forgiveness is now. We are not promised tomorrow. -- Rick C. Hodgin PS -- If you would like prayer, please email me. My family and I will add you to our prayer list. |

| rick.c.hodgin@gmail.com: May 03 06:55PM -0700 You know the most compelling reason to believe the rapture will take place very soon (days, weeks, months, years, but not more than a few years) is that the technology needed to fulfill every aspect of the requirements of the one-world government, the mark system, the one-world economy, is here today, and it wasn't here five to ten years ago. AND... the Bible DOES NOT describe greater technology. I think we'd all admit that in five to ten years we'd have greater technology. Watch the videos, my friends. They teach you the truth about what's coming, and what I pray you'll escape. -- Rick C. Hodgin PS - God is calling people to repentance now. Those who are wise will heed the call. The video series explains why. |

We did not do any refactoring, just switched to the newer compiler, set up the command-line options and started using C++11 features. As the programmers became better familiar with C++11 features they would sometimes replace a piece of the old code when there was a need to fix a bug or change or add a feature with the code using C++11 features. I think our approach was close to optimal: where we did not need to change code for a business reason or to fix a bug, maybe it was better to not touch it at all (based on the principle to not touch what's either working or useless). Otherwise, we had a chance to incrementally change it later wherever it was most beneficial. -Pavel |

The same cannot be said about compiler versions, in general one can expect more porting problems when upgrading compiler versions. So take care to not use an old compiler version for you C++03. Use the latest available compiler in C++03 mode, at least on some platform. If you have to use an old compiler on the other platform(s), then expect some porting efforts between the platforms. |

That's good advice; our embedded product uses gcc for the target but clang and VS2017 for development and test builds. One other useful thing that I have done (and currently do!) is use the latest supported standard for unit tests to familiarise myself and the other team members with the latest and greatest features. This is a great way to engage people in writing unit tests! -- Ian. |

Steinbach wrote: > invoke the for-collections overload of `<<`. > Simply, explicit = good, implicit = not so good, in general. > - Alf Sorry, I left then without seeing your answer. I think your answer and mine are equally patchy but both solve the original problem .. almost (see below). My code (here and below I mean OP's issue only) explicitly use value_type and both mine and your code implicitly use const_iterator; each would make Collection deducible by expressing only one of the container requirements in the additional template parameter and neither would express all restrictions. To put container subject to bed, if we believe a collection is a container, we could just use both mine and yours parameters and by that become more accurate but still inexact as containers have other requirements. I have never intended to express all restrictions though, just to solve the issue. What is more interesting to me, however, is the vague definition of "collection" in the OP post. Seems both of us have read that as "container". I am now having a second thought because a better (more general and suitable to OP code) definition for "collection" would be a range-expression usable in range-based "for" statement -- because it is its only property that the OP code actually depends on (other than being able to insert the element to stream; but that the requirement on element rather than collection type). Unfortunately, neither mine nor your code works on something like "int a[] = {5,6,7};" I actually tried to get it working by changing the second template parameter to "typename T = decltype(*std::begin(Collection()))"; that works for list and vector but produces wrong result for int[] (due to automatic conversion to int*, I believe). I may return to this later unless solved by you or someone else. The current plan is to define some "range_expression_traits" class template that would cover all cases of range expressions usable in range-based "for" (again, I don't see it useful to try to cover all restrictions but rather to make all interesting usages work although in this case the restrictions are minimal so they might as well get all covered automatically). I wonder though if some for-range-expression check or trait already exists so I will be re-inventing the wheel. On a side note, I would not want to require client code specify wrapper or otherwise be anyhow changed; to me the challenge is to make the code that seemingly should work out-of-box work out-of-box if at all possible. -Pavel |
