Are shift and goto moves for all LR parsers ( LR(0), SLR(1),CLR(1),LALR(1) ) same?

I understand the difference in the parsing tables of the above 4 parsers. I understand that CLR>LALR>SLR>LR(0) in terms of power.

Are shift and goto moves for all LR parsers ( LR(0), SLR(1),CLR(1),LALR(1) ) same?. I think goto should vary as reduce moves vary? Also, if a grammar is accepted by CLR(1) parser, for which parser it would have highest and lowest no. of reduce moves or would it be the same? Please explain

COMMAND or SHIFT key modifiers always activated

Regularly, when I am using Photoshop CC 2018 (mostly) suddently I got a modifier key who stay always activated sometime it is the COMMAND key, or sometimes the SHIFT key which make impossible to work with these kind of applications using intensly the modifiers keys for almost anything…

The only way is to reboot, but even so, I suspect that when I have rebooted and relaunched Adobe Photoshop, the mean bad appends very quickly, so very hard / almost impossible to work

Here is my setting : MacPro 4,1 (Nehalem) with Mac OS X 10.11.6 El Capitan and the Adobe CC 2018 suite///

also, I have a WACOM INTUOS 4 Tablet, (actually with driver 6.3.32-4) BUT I got the bug since several previous version of the wacom tablet driver and (suprise) a mouse and a keyboard. worth mentionning : the keyboard is actually a window keyboard. but it didn’t need any driver to install. I just got few key not related to mac function, but even the F1 to F15 key function work as intended by apple when using it with the FN key (SOUND UP/ DOWN / MUTE and misssion control etc…)

Please is anybody can help me plizzz ?!

Thanks very much in very advance ! Tell me if you need a EtreCheck Report, (?) if so I can quickly post a link of my current report.


shift sin(2^x) to the left

I’m needing to be able to shift this equation to the left or right, but can’t figure out how. It’s for a programming project that I’m working on, and I need to model a wave that slowly progresses from short bursts into long big bursts.

Can a genie use its Plane Shift ability on unwilling creatures?

A Genie has the SP ability of a limited plane shift.

A genie can enter any of the elemental planes, the Astral Plane, or the Material Plane. This ability transports the genie and up to eight other creatures, provided they all link hands with the genie. It is otherwise similar to the spell of the same name (caster level 13th).

The Plane Shift spell has two versions.

One targets a creature touched, the other several hand-held, willing creatures.

Can the Genie use its Plane Shift on an unwilling creature, or is it limited to the willing version (seeing as it mentions ‘itself and others’, per the willing-group version)?

Does shift consequence allow damage to be transferred to beings or only to objects?

Does shift consequence allow damage to be transferred to beings or only to objects?

The wording is a bit… complicated, as such I’m a bit unsure if damage can only be transferred onto objects or also onto other beings:

The demon shifts the consequence to another eligible target. If the consequence is damage, the demon can change it to an inanimate object

Shift + Tab key combo no longer works

The Shift + Tab key combo used to:

  1. Navigate back in browsers

  2. Un-indent text in my text editor

no longer works. It appears the functionality to this key-mapping has completely disappeared and I am at a loss as to how to regain it.

Does anyone have any suggestions on how to reimplement it?

I am using a Late 2012 Mac mini running macOS Mojave 10.14.4.

Fractional integration in term of shift operator

I am trying to understand the fractional derivation and fractional integration. I found a representation of the fractional derivation operator in term of shift operator that is:

$ D^n=(1-S)^n = \sum_{k=0}^{+\infty}\frac{\Gamma(k-n)S^k}{\Gamma(-k)\Gamma(n+1)}$

If I define the integration as the inverse of derivation, I must have

$ I\cdot D = 1$

where I define $ I$ as the integration operator.

So, my question is can I have a representation of the fractional integration in terms of operator $ S$ as

$ I^n\cdot D^n = D^{-n}\cdot D^n = 1$


$ I^n = \sum_{k=0}^{+\infty}\frac{\Gamma(k+n)S^k}{\Gamma(-k)\Gamma(-n+1)}$ ?

What explains the current shift from glossy UIs to matte UIs?

I’ve noticed an interesting phenomenon in the user interfaces of many famous applications, they’re moving away from the glossy complex to a more dull and bare minimum design.

Why the sudden change? It also appears that most of these companies have adopted this design around the same time, was that linked to some new study?


Examples of icons that have changed from a glossy look to a flatter one, including Lync, Skype, Photoshop,, Chrome and others
